The latest culture methods and matters needing attention of Taxus mairei

The yew does not look very beautiful, but it does release oxygen and purify the air indoors. It is a necessary flower plant at home. What is the breeding method of the yew? What problems should be paid attention to in yew culture? Below, the editor of Guizhou Agricultural Network will introduce the breeding methods and matters needing attention of Taxus mairei.

Culture methods of Taxus mairei

1. Aquaculture climate: the most important thing is to adapt to the climate. Taxus grows in subtropics and tropics, and the climate should be humid and rainy all the year round. Of course, it has something to do with the variety, except for the northeast yew.

2. Daily care

① watering: like to be wet and not resistant to waterlogging, often spray foliar water, pan soil is not dry and not watered, watering should be thoroughly

② fertilization: the growth period of Taxus mairei is from March to October and dormancy period from November to February every year. The rapeseed cake is nitrogen fertilizer at the beginning of March to April, and then diluted and retted rapeseed cake liquid is applied every 20 days or so to meet the needs of the growing period.

③ pruning: pruning begins in February every year, and it is best not to move during the growing period.

3. The yew at the seedling stage is the shade plant (all the three years after germination are at the seedling stage). After three years, the yew is not a shade plant. It is necessary to see the sun gradually, and the adulthood is direct all-day light, otherwise it will be finished. Many families put them at home after three years and they will lack light and grow poorly until they die.

4, insect pests, are common management and other flowers, spray several times before the rainy season diluted Bordeaux liquid, there are insects to dilute dimethoate.

Maintenance of bonsai of Taxus chinensis

1. Try not to spray fertilizer on the leaves of the newly purchased yew bonsai just sprouting, because at this time the yew bonsai has not really survived or the leaves are too tender, if fertilization will make the leaves or buds shrink and curl. Thus affect the normal germination of new roots, foliar spraying water is not too much, to the foliar surface can see the spray of water but not dripping down for the degree. Spray two hours before dark in the afternoon, do not leave water droplets in the evening (especially when there is a large amount of water), otherwise it will affect the normal growth of tender leaves or the leaves will turn yellow, affecting the healthy growth of plants. The reverse side of the leaf can be sprayed more than the front, because there is a waxy protective film on the front of the leaf, which will hinder the absorption of nutrients and water, while the back of the leaf has no waxy layer, has more stomata and has a strong ability to absorb water and fertilizer. So the back absorbs faster and more than the leaf surface. Depending on the situation and the temperature, once a day or two or three times a day. Note that the room should be ventilated regularly.

2. For the newly purchased yew bonsai, due to the damage to part of the root system when transplanting from the planting base to the flowerpot, the nutrient supply between the root and the branches and leaves is out of balance, especially for the bonsai with luxuriant branches and leaves. the evaporation of the leaf surface is greater than that of the root system, and the top leaf curls and dries when the potted soil remains moist, so it is best to prune the branches and leaves properly in order to reduce the moisture of the branches and leaves. Excessive consumption of nutrients should restore root growth as soon as possible, and at the same time, watering should be controlled to keep the basin soil slightly dry, so as to facilitate root growth as soon as possible and speed up the restoration of normal nutrient supply. At the same time, Taxus has strong sprouting ability, especially the new branch growth ability is strong and resistant to pruning, and it will sprout new branches and leaves soon after survival. When necessary, plant rooting or rooting enhancers can be used to irrigate the basin soil every seven days or so, and continuously irrigate three or four times (using good quality products and not too much water) so that the roots can grow quickly and healthily. Restore the supply balance between roots and leaves as soon as possible, and make the yew grow well.

3. As the yew bonsai has limited nutrients planted in the flowerpot, it can only provide about half a year for growth, or now the plant shape is larger and the nutrient consumption is very large, so consumers are advised to replace the original pot as soon as possible after purchase. Because our company for bonsai for more than a month of re-bonsai, and stored in the distribution company for a period of time, plus yew like rich and loose soil. It is best to change the basin as soon as possible, when changing the pot to calculate the inner diameter of the flowerpot, the inner diameter of the new pot should be at least five centimeters larger. Before the new buds germinate in February and March every year, pour out the tree and the pot soil together when the basin soil is not dry or wet. Try not to break the original soil ball, if you find that there are too many roots after survival, you can properly cut off the bad roots, put the tree in a new basin, fill it with nutritious soil and press it gently, and only close the soil and roots in the basin can you improve the survival rate. otherwise, the plant is not easy to survive or does not grow vigorously. However, the soil should not be pressed too firmly, if the air cannot be breathed from the roots, the roots will rot and the plants will die. Water thoroughly immediately after planting. And leave the basin in the shade for a few days. After watering, the basin soil can no longer be turned over and pressed, otherwise the basin soil is easy to consolidate, or the soil is too solid and breathable and easy to cause rotten roots.

4. Fertilization methods of yew bonsai: nitrogen, phosphorus and potassium fertilizer can promote the growth of flowers and plants, phosphorus fertilizer can promote the formation of flowers and fruits, and potassium fertilizer can promote the growth of stems and roots. Because the bonsai is in a limited bowl space. Limited cultivation soil, organic matter is broken down into inorganic salts by bacteria and absorbed by roots. With the consumption of Taxus growth, the nutrients in the basin soil are gradually lacking, resulting in insufficient demand for growth. Although the prepared nutritious soil is used in the bonsai, do not apply fertilizer within three months after buying it back. As long as every seven to ten days, pour about 1000 times of potassium dihydrogen phosphate solution or foliar spray in the evening. Control the amount of water and don't water too much. Only when the leaf color becomes pale, the plant is thin, the leaf is yellowish white, the leaf tip appears "dry burning edge", and the leaf senescence occurs prematurely, apply 1000 times liquid urea and potassium sulfate 800x instant high quality compound fertilizer solution to remove sediment and then irrigate the basin soil. once every other month or so, it is best to use fully mature light bean cake fertilizer water (about 10% 15%) to avoid the tree trunk and apply along the basin wall as far as possible. Apply once a month. Pour clean water again the next day after fertilization, in case the fertilizer is too thick and dilute, the above two fertilizers can be used alternately, or you can dig two small pits in each basin and put five or six grains of urea and seven or eight grains of high-quality compound fertilizer in it. Then cover the soil and water it to dissolve the fertilizer. Taxus bonsai is not allowed to apply raw fertilizer and thick fertilizer. Topdressing should be based on nitrogen and phosphorus fertilizer, not too thick.

5. the watering method of bonsai: the principle is "no dry, no watering, watering thoroughly".

Water is an important part of flowers and trees, all life activities of flowers and trees should be carried out with the participation of water, whether photosynthesis or transpiration, can not be separated from water, water can maintain the swelling and pressure of cells and make branches and leaves straight. But beyond the limit, the plant growth is thin and weak, such as long-term basin soil too much water, it will cause leaves yellowing, deciduous leaves, rotten roots, and even death.

① saw that the surface color of the basin soil became slightly lighter and the leaves slightly curled, and pressed the basin soil with his fingers to feel a little soft. when the sound from tapping the middle and upper part of the basin body with finger joints was relatively dull, the basin soil did not need to be watered, as long as the leaves were sprayed to supplement the moisture of the leaves. When the surface of the soil is white, press with your fingers and feel that the soil is hard, and there is a circle of cracks between the basin and the soil, when tapping the middle and upper part of the basin with finger joints gives a clear sound of "bang bang", when the young leaves of the new shoots are withered, the basin soil should be watered. The cracks between the soil and the basin should be compacted with hard objects before watering, and then poured with a large spoon. When pouring water, the spoon should be close to the edge of the basin, and the spoon should be poured in all at once, so that the basin soil can absorb enough water. If you pour a small amount of water into the basin for a while, you can see that the water flows out quickly from the bottom of the basin, indicating that the soil and the basin are not completely compacted. The gap between the basin wall and the soil is pressed and then poured by the application object. When the basin soil structure is normal, it is better for water to seep out slowly from the bottom of the basin for about 40 seconds to one minute after watering. The water temperature must be close to or consistent with the air temperature at that time. When using tap water, you should first put the water in the sun for about three hours before watering, because the light helps to decompose the oxides in the tap water and increase the water temperature. You can also put the water in the big basin for half a day or one night and then water it. If there are many bonsai, you'd better put the water in the big tank to make the water temperature as close as possible to the air temperature and soil temperature. Especially in the hot season, in addition to watering the basin soil, it is also necessary to spray water spray on the leaves to keep them moist for growth. When the basin soil can be kept a little dry and not too wet, each basin must be checked in the light of the actual situation, and be careful not to water too much.

The leaves of ② yew are evergreen all the year round and are suitable for indoor display. However, the yew bonsai is not easy to be placed in the air outlet of the air conditioner, otherwise it will increase the water evaporation of the yew leaves, easily cause the branches and leaves of the yew to dehydrate quickly, and cause the leaves to curl and dry up. If you turn on the air conditioner in the air conditioner room every day, you should spray the foliar surface every day to maintain the foliar humidity and put a basin of water indoors. In the room with heating in winter in the north, the heat sink should be dispersed far away, and a basin of water should be put on the radiator to increase the indoor air humidity. Summer and autumn temperature more than 30 degrees Celsius should strengthen shading and cooling work, can be moved to the north ventilated room. Spray water to cool down when necessary to create a cool, moist environment to facilitate the growth of the yew. And avoid the western sun shining directly on the room on the yew bonsai. The watering amount of bonsai should be controlled in winter to avoid long-term over-wetness of potted soil, because the plant growth is not exuberant in winter, the volatile water of leaves is less, if the potted soil is too wet for a long time, the surface of potted soil will be hardened and impervious, and it is easy to cause rotten roots. The yew must pay attention to the indoor ventilation when raising the yew indoors.

③ yew planting soil should be loose, rich in humus, fertile, slightly acidic soil (between PH=5.5~7), yew bonsai can not pour tea water, if often pour the rest of the tea water, because the tea water contains theophylline, and other alkaloids. If the pH of the soil is changed for a while, it will also destroy the organic matter nutrients in the soil. It can inhibit the growth of Taxus and cause excessive soil moisture, hinder the ventilation of basin soil, and cause root rot and stem rot. When there are conditions for a week or so, moving the yew bonsai to the balcony in the evening to receive dew and exposing it to the sun for about one or two hours in the morning (before 10:00 in the morning) is beneficial to the growth of the yew and improve its disease resistance. In summer and autumn, it is necessary to prevent the western sun from shining directly on the yew through the window, so as to prevent the high temperature burning leaves from affecting the ornamental value.

Matters needing attention in the culture of Taxus mairei

1. The yew should pay attention to the adjustment of light because the tree is small, so it needs light, but it can not be placed in the strong light for too long. Generally, it can be basked in about two hours before ten o'clock in the morning or after five o'clock every day in summer and autumn. Usually accept more scattered sunlight. Otherwise, the leaf tip will be scorched yellow due to strong light burns, and the indoor ventilation will be maintained, so that the indoor air will not be withered, sagging and other bad growth phenomena.

2. If the young leaves of the new bonsai appear dark yellow and dull, the withering phenomenon of the top of the new shoot is generally caused by overwatering too much soil and impermeable so that part of the roots rot and absorb water. When the ability to absorb fertilizer is weakened, the amount of water should be controlled if the symptoms are mild, and the basin surface soil should be gently loosened with hard and blunt objects to make the basin soil breathable, move to a place that can accept dew every night, and move to a shady place at eight or nine o'clock in the morning, which is conducive to the healthy growth of the root system. If the leaves are yellowed and curled in a short period of time, it means that the root rot is serious, because immediately turn the basin to check the root rot condition, (the normal fibrous root shows a full white shape), if more than half, generally save not alive.

3. Yellow leaves occur in the old leaves from the bottom up, but the new leaves generally grow normally, which is generally caused by the lack of water in the roots and the lack of water in the roots. Sometimes the top leaves dry and curl, touch the dry leaves fall, but the old leaves grow normally, generally caused by the lack of water in the roots, should be watered thoroughly at one time. When watering, the cracks on the edge of the basin must be compacted with objects to prevent the water from quickly leaking from the cracks. To create the illusion of being thoroughly watered, the roots will die due to lack of water over a long time. Move outdoors at night to accept more rain and dew, and receive two hours of sunshine in the morning and evening to restore the growth of the yew.

4. Taxus is suitable for weakly acidic soil. If it is irrigated with alkaline water for a long time, it will cause leaves to change from green to yellow, or even leaves to fall off, due to the addition of acidic nutrients or spraying leaves or watering basin soil with 2/1000 ferrous sulfate solution, once every ten days, three times in a row. It can make the leaves turn green due to alkali yellow.

5. In March and April every year, the yew will sprout a large number of buds and consume a lot of nutrients. At this time, the buds growing toward the inside can be removed to prevent the leaves from yellowing or falling off because the branches are too dense and unventilated. For cross branches, inward branches grow and cut sparsely, which can improve ventilation. Transparent light, and can save the excessive consumption of water and nutrients, it is best not to spray liquid fertilizer on the leaf surface at the beginning of bud germination, or to pour thick fertilizer on the root.

6. if the normal amount of fertilizer is applied with urea alone, the concentration of nitrogen fertilizer is generally 1/1000, and if potassium dihydrogen phosphate is used alone, the concentration of phosphate fertilizer is 1/1000 to 2/1000, with an interval of seven to ten days.
