Matters needing attention in the maintenance of Pear trees

In the process of pear tree growth, pruning must be carried out in time, cutting off the overgrown branches and cross branches to promote the lower branches, cultivate compact groups of branches, and at the same time make the bonsai achieve a clear and dense natural and beautiful artistic effect. As the leaves of pear trees are sensitive to water supply, if the water supply is insufficient, the leaves often wilt, and they will dry up and fall off for a long time, so the cultivation should be dry and immediately irrigated to avoid excessive soil drought.

The above is the introduction of the cultivation methods of pear trees. I hope this article can be helpful to you! If you want to know more, please follow the four Seasons Plant Network!

How to cultivate pear bonsai? points for attention in maintenance of pear bonsai

Flower bonsai network guide: today the flower bonsai network editor to share with you is about how to raise pear bonsai, pear bonsai maintenance points for attention of the article, let's take a look.

Pear trees like warm, humid and sunny growing environment, with strong adaptability. If you do a good job in daily maintenance, you will be able to enjoy the beautiful pear bonsai. So, how to raise pear bonsai?

Pear trees like warm, humid and sunny environment, and have strong adaptability to the environment, cold and high temperature-during the growing period, pear trees can be maintained in places with good ventilation and plenty of sunny. if the light is not enough, the branches will not grow fully and the flower buds will not be full. Winter can be placed in the cold indoor or outdoor shelter to the sun to winter, keep the basin soil free of ice to survive the winter safely.

How to raise temperature and light of pear bonsai

Pear trees like warm, humid and sunny growth environment, strong adaptability, cold and high temperature resistance. During the growing period of the pear tree, it is suitable to keep it in a place with good ventilation and plenty of sunshine. If the light is not enough, the growth of the branches will not be full and the flower buds will not be full. In winter, bonsai can be placed in a cool indoor or outdoor sunny place to keep the basin soil free from ice and survive the winter safely.

Moisture content

Pear leaves are sensitive to water, insufficient water supply is easy to cause wilting, a little longer will dry up and fall off, lack of water will directly affect the fruit setting rate and the growth of young fruits. Therefore, watering can be achieved in daily maintenance to avoid excessive dryness of the soil. Especially in the high temperature and dry weather in summer, we should also spray water to the leaves.

Fertilizer

Pear trees need a large amount of fertilizer, in addition to the pot must be fully applied when the base fertilizer, in the growing season of pear trees, generally every 15-20 days need to apply mature organic liquid fertilizer. In addition to normal fertilization, it is necessary to apply more phosphorus and potassium fertilizer in the budding stage, flower bud differentiation stage and fruit expansion stage of pear trees. 0.2-0.3 potassium dihydrogen phosphate solution can be sprayed on the leaves for 2-3 times to meet the nutritional requirements of flowering and fruiting.

Basin soil

The basin turning work is carried out every 1-2 years, which is suitable for spring. The selection of basin soil should be the neutral sandy soil with loose and fertile soil and good drainage, and the ph value is in the range of 5.88.5.

Pruning

Matters needing attention in the maintenance of pear bonsai

Pruning work in time, cutting off long branches, cross branches, overlapping branches, dead branches, cutting short strong branches to promote the lower branches, and cultivate compact fruiting branches. At the same time, it makes the bonsai achieve a clear and dense natural and beautiful artistic effect.

Because the leaves of pear trees are sensitive to water supply, if the water supply is insufficient, the leaves often wilt, and the leaves will wither and fall off for a long time, especially in the pre-flowering stage, post-flowering stage and fast-growing period of fruit, if there is no sufficient water supply, it can directly affect the fruit setting rate, young fruit growth and fruit weight gain in the later stage. Therefore, the management method of pear bonsai should be sprayed to the leaves when the summer high temperature is dry, and the management method of pear bonsai should be considered.

The middle and lower sentence of June is the period of flower bud differentiation, and short-term drought treatment can be carried out to inhibit the growth of new shoots, increase the proportion of medium and short branches and promote flower bud differentiation by wilting-watering-wilting-watering for about 20 days, and the upper and middle sentences in June can also cut or cut the trunk or main branch in order to increase the proportion of medium and short fruit branches. Watering should be properly controlled in autumn, and soil moisture should be checked frequently in winter to replenish water in time to avoid dry-frozen pear bonsai management. the management method of pear bonsai comes from

Pear trees need a large amount of fertilizer, so it is necessary to apply sufficient basic fertilizer when potting, and to apply mature organic liquid fertilizer every 15 to 20 days in the growing season. In the budding stage, flower bud differentiation stage and fruit expansion stage, in addition to normal fertilization, the amount of phosphorus and potassium fertilizer should be increased by spraying 0.2 to 0.3 potassium dihydrogen phosphate solution to the leaves for 2 to 3 times to meet the flowering and nutrition requirements.

After the tree shape is basically stable, attention should be paid to maintaining the vigorous growth of the tree potential to make it bear fruit year after year, combined with pruning and shaping, cutting off overgrown branches, cross branches, overlapping branches and dead branches, cutting short strong and strong branches, and promoting the sprouting of the lower part to develop into branches. to cultivate compact fruiting branches. And make the bonsai level clear, dense and elegant, to achieve the natural and beautiful artistic effect of pear tree bonsai management method flower encyclopedia.

Due to the limited nutrition in the basin, the fruit left should not be too much, generally leaving 1 to 2 fruits per inflorescence, or even the whole inflorescence can be removed. The basin is turned every spring of 1 to 2 years, and the basin soil should be loose, fertile and well-drained neutral sandy soil, with a ph between 5.8 and 8.5.

I. Biological characteristics

The root system of pear is well developed, and it is easy to produce new roots after root cutting, and there are two growth peaks in a year. Pear flower buds are mixed flower buds, the shape is large and full, most of them are terminal. Fruiting branches can be divided into long, medium and short fruiting branches and short fruiting branches according to their length. When making pear bonsai, short fruit branches and short fruit branch groups should be cultivated and utilized as far as possible to make their shape compact and plump.

Pear is a light-loving tree species, when the light is insufficient, the branch growth is not full, the flower bud formation is not full. Pears have strong cold resistance during dormant period, and potted pears can survive the winter when they are placed in the leeward and sunny place in the central part of Hebei Province. Pears like fertilizer, and the cultivated soil should be loose and fertile.

II. Material selection and cultivation

There are many rootstocks suitable for pears, such as mountain pear, du pear, etc., which can not only be propagated, but also easy to be collected in the mountain area. When collecting in the mountain field, the mountain pear is a better pear rootstock, and its growth potential is strong, and its root system is well developed. when it is returned to the nursery or directly installed in the basin after harvest, the survival rate is high. The purpose of rapid growth and prototyping can be achieved by using small trees or large seedlings with lower branching points in the garden, moderately re-cutting their branches and roots, and directly installing pots to protect them.

Third, the process of potting.

(1) nutritious soil

Pears can grow normally in the range of pH 5.8 to 8.5, and adapt to the pH and salt content of basin soil in a wide range.

(2) use the basin

The root system of pear is well developed and the growth potential is strong, so it is appropriate to choose a deeper vegetable pot when planting for the first time. After forming, it is changed into the purple sand basin. The selection of purple sand basin should be determined by the modeling requirements of the tree body, in general, the use of shallow basin should be avoided as far as possible. If the shallow basin must be used, it should be transferred back to the larger basin after the viewing period to meet the nutrient requirements of the tree.

(3) planting

The suitable potting period of pear is before sprouting in spring and after defoliation in autumn. Before potting, the aboveground branches were moderately heavy and truncated according to the modeling requirements, so as to reduce nutrient consumption and improve the survival rate. The treatment of the root system should be based on the principle of retaining the fibrous root as much as possible, and the root with suitable thickness and length can be placed in a basin to lay the foundation for raising the root in the future; when cutting the thicker root, pay attention to the angle of the cutting blade as far as possible, so as not to form a wound exposure when lifting the root later, affecting the ornamental.

(4) styling

Pear bonsai can be modeled in many forms, such as curved dry, curved dry, oblique dry, cliff, jungle, low dry happy, high dry stratified and so on. Because the pear tree has strong growth potential, large annual growth and strong top branches, no matter what shape it is, strong and strong branches should be controlled to form a short, compact, natural and beautiful shape.

Since the 1990s, the author has cultivated more than a thousand pots of pear trees, and most of his successful works come from rootstocks collected in the depths of Taihang Mountains. this kind of rootstocks are more than decades old and are convenient for a variety of shapes. After several years of potting, the trees are full of fruitful fruits, coupled with vigorous and simple stumps, which are easy to form a wonderful ornamental effect. The cultivation of this kind of stump mainly adopts the method of cutting and storing branches, so that new branches are formed on the head of the stump, and then grafted to form a new crown.

Pear fruit shape is larger, in the pear tree bonsai, the fruit is one of the main body of the picture, "no fruit does not make a scene". The number, size and distribution of fruits vary from year to year and even from season to season. Therefore, in the production of this kind of bonsai, we should pay attention to the selection and cultivation of pile shape in the early stage. after entering the fruiting period, we should pay attention to the change of tree crown, fruit cultivation, determine the distribution of fruit, and outline the gorgeous picture of bonsai of fruit trees with distinct seasons and rich changes. Specific methods such as ① bending shaping. Bend the trunk of the bonsai to make it lively and unrestrained, flexible and changeable, just like a swimming dragon, to achieve the effect of being soft and handsome. This method is mostly used for young trees or perennial pots with a diameter of less than 5 cm, smooth trunk without scar and high branching point. ② truncated and stored branches. It is the main method of pear bonsai modeling and training. Pear latent buds have a long life and are easy to branch after stimulation, and they are often sawed for more than ten years, and good branches can still be produced from latent buds at the sawing site. Therefore, on the basis of retaining the pile shape, the pear pile can be boldly cut off its branches, or re-cultivate the branches and crowns, or adjust the direction of the tree shape, so as to increase the proportion of thickness between the top and bottom, and form the style of towering giant trees in a smaller space.

IV. Plastic surgery skills

Before the fruit of pear bonsai, the top advantage of young trees is obvious, the annual growth of branches is larger, and the branches are less. We should adjust the direction of forming branches, increase the number of backbone branches, control strong branches and promote short branches by means of drawing branches, twisting branches, bending, truncation and so on. Cultivate into a robust fruiting branch group to form a shorter crown. In the early fruiting stage, on the basis of continuing the shaping work, the emphasis should be placed on the cultivation of fruiting branches and fruiting branches close to the inner chamber, so that the inside and outside branches and leaves of the potted trees are full, bear fruit year after year, and their growth and development are balanced.

Combined with shaping and pruning, for long branches, strong branches and medium growing branches, those with space were moderately cut short and flattened in the middle and lower parts, which promoted the lower buds to germinate into branches and cultivated into compact fruiting branches. In order to prevent the fruit part from moving outward and the tree shape confused, the weak front branches of the tree are moderately retracted, the overlapping crosses are removed and the tree branches are disturbed, so that the hierarchy is clear, dense and orderly, and the whole is vigorous, tall and straight. through a small part to see the natural and beautiful form of the whole.

V. maintenance and management

(1) fertilization

Pear bonsai requires a large amount of fertilizer, and organic fertilizer is generally applied every 10 to 15 days in the growing season. In the budding stage, flower bud differentiation stage and fruit expansion stage, in addition to 150 times of organic liquid fertilizer, phosphate and potassium fertilizer should also be applied to meet the needs of flowering, fruiting and tree growth.

(2) watering

Pear trees need sufficient water supply in the whole growing period, and the leaves of pear trees are very sensitive to water, wilting if there is a little loss of water, and scorching and shedding after a little longer time. In the growing season, such as early flowering, late flowering and long-term fruit speed, such as insufficient water supply, it can directly affect the fruit setting rate, young fruit growth and fruit weight gain in the later stage. Therefore, the growing season should be watered according to the soil moisture in the basin. When the temperature is high and the air humidity is small, spray water on the leaves at noon or in the afternoon. Pay attention to drainage on continuous rainy days. Early spring according to soil moisture timely watering, to prevent the occurrence of strip phenomenon.

(3) promoting flowers

The short-term drought treatment was carried out in the middle and late June, which could obviously inhibit the growth of new shoots, increase the proportion of middle and short branches and promote the formation of flower buds.

(4) Fruit protection

The seed setting rate of self-pollination of most pear varieties is very low, and artificial pollination is needed when the number of potted plants is small or the varieties are single.

(5) overwintering against cold

The cold resistance of pear is strong. In the central and southern part of North China, we can choose the unsheltered leeward and sunny place in the south to overwinter. However, it is necessary to check the soil moisture frequently and replenish the water in time.

Matters needing attention in culturing pear trees

Pear trees love light very much, and sufficient light is conducive to its photosynthesis and the formation of organic matter, which has a great effect on the growth of all organs of pear trees. If the lack of light will lead to the slow growth of the pear tree, and will make the whole pear tree stunted, but also affect the immunity of the pear tree. The lack of light in the fruiting period of pear trees will also affect the quality of the fruit.

The above is about the pear tree seedling method introduction! Before raising seedlings, the choice of topography is particularly important. Be sure to choose a place with fertile soil and plenty of light for conservation!
