Culture method of potted lemon

We all know that lemon is a good thing, which is very good for human health. In fact, our family can also grow lemons, so what is the cultivation method of potted lemons? Below, the editor of Boqi Network will sort out some opinions given by experts to give you a reference.

Potted lemon

Lemon pot technology mainly has the following points: raising seedlings and potting. A large amount of cultivation in the south, suitable for grafting propagation; less cultivation in the north, mainly using cutting methods, can also buy grafted seedlings cultivation. The root system of lemon has higher requirements for water, nutrients and soil, and the pot soil should be made into water and air permeability, water and fertilizer conservation, and slightly acidic culture soil. The time of putting on the basin and changing the basin is available after autumn and early spring, and can be flexibly controlled according to the local climate.

Light and temperature

Lemon is a light-loving plant, but if the sun is too strong, it will grow poorly. Generally, at noon, the annual average temperature for plant replacement is more than 15 ℃, and the optimum growth temperature is 23 ℃ to 29 ℃. If the plant stops growing at more than 35 ℃, it will be damaged by freezing at-2 ℃. Lemons generally do not need to cool down in summer, enter the room before Frosts Descent and leave the room after Qingming Festival, which can survive the winter safely.

Watering and fertilization

Lemon needs more water in its growth and development, but it is not easy to rot its roots if it has too much water. Generally speaking, spring is the time for shoots to spread leaves, pregnant buds to blossom, and appropriate watering. The summer light is strong, the temperature is high, needs more water. However, it should be timely and appropriate, otherwise it will cause fruit drop. Autumn is the period of shoot growth and rapid fruit expansion, so there must be sufficient water. Late autumn and winter are the period of flower bud differentiation, while the basin soil is dry. Lemon prefer fertilizer, in addition to the basin, change the basin to apply sufficient base fertilizer, the growth period should adhere to the principle of thin fertilizer and frequent application. The times and amount of fertilization should be determined according to the growth and phenological period. For example, it is better to apply liquid fertilizer to fully fermented cake fertilizer and water, and the ratio of cake to water is 1VR 200. The soil in the north is slightly alkaline, so ferrous sulfate can be added to the fertilizer solution to form a slightly acidic nutrient solution.

Pruning

Pruning is generally divided into winter shears and summer shears. Winter shearing should be based on the principle of "cutting density and keeping thinning, getting rid of weak and strong", cutting off withered branches, cutting weak branches and overgrown branches without the effect of initial space. Summer pruning mainly truncates the overlong branches on the fruitless tree, erases the summer shoots on the fruiting tree, and shortens the declining branches in the middle and upper part of the crown.

Flower promotion and fruit preservation

Lemon is the tree species that blossom and bear fruit in the four seasons, while most of the potted plants in the north blossom and bear fruit in spring. Therefore, it is necessary to control the water after the autumn shoot stops growing. Wait for both sides of the leaves to begin to roll, and then moderate watering to promote flower bud differentiation. Pay attention to fertilization in the basin and foliar spraying to cultivate robust fruiting mother branches.

The main measures to protect fruit are: first, to strengthen the supply of fertilizer and water and accumulate nutrients; second, to carry out artificial pollination; third, to thinning flowers and fruits. Lemon fruit is large and needs more nutrients, with a normal leaf-fruit ratio of 30 to 40:1. According to the principle of removing the weak, staying strong and evenly distributed, first remove too many and too dense buds; then remove part of the fruit when the young fruit is 1cm in size; finally, after the physiological fruit drop, the fruit is determined according to the ratio of leaf to fruit. It can also leave a weak branch and a strong branch with only one fruit.

The cultivation method of potted lemon lemon is a small evergreen tree of the genus Citrus in Rutaceae. Leaf blade small, long oval, leaf margin serrulate. Flowers are solitary, blooming all the year round and full of fragrance. The fruit is oval or ovate and ripens in autumn and winter. The peel is yellow, the pulp is very sour and fragrant, the fruit juice is citric acid, and the peel can extract lemon oil. Lemon pot cultivation techniques are mainly as follows: large amount of seedlings and pot cultivation in the south, suitable for grafting propagation; less cultivation in the north, mainly using cutting methods, and grafting seedlings can also be purchased. The root system of lemon has higher requirements for water, nutrients and soil, and the pot soil should be made into water and air permeability, water and fertilizer conservation, and slightly acidic culture soil.

It can also leave a weak branch and a strong branch with only one fruit. Let potted lemons bear good fruit in order to make potted lemons bear more fruit, we should pay attention to nine links: first, change pots and change soil: potted lemons must turn pots and change soil from March to April in spring. If the flowerpot is too small, you can change the adaptive flowerpot, if the flowerpot is still suitable, the original pot can be replaced with new soil, and the bottom fertilizer should be applied when changing the pot. Second, spring pruning: spring pruning in combination with changing pots in spring, cutting off inner bore branches, withered branches and leaves, roots and leaves of diseases and insect pests, and growing branches, so as to facilitate the plant to hang fruit. Third, rational fertilization: lemon plants should be fertilized many times before flowering and after fruit hanging, multi-element flower fertilizer should be applied once a month, and flower nutrient solution should be sprayed once a month to ensure that the fruit is not easy to fall off. Fourth, prevent fallen leaves: fallen leaves affect the fruit of lemons, in order to avoid falling leaves, in the daily management work, avoid watering too much and less. Fifth, noon shading: after the lemon plant blossoms to before hanging fruit, when the noon temperature exceeds 30 ℃, it should be shaded for about 3 hours, otherwise it will affect the normal shape of flowers and hinder the plant from hanging fruit. 6. Artificial pollination: artificial pollination is an important measure for multi-hanging fruit. Pollination should be carried out in time after the petals grow, and this work should be carried out around 9 o'clock every morning with better results. Seventh, prevention and control of diseases and insect pests: summer and autumn is the season of frequent occurrence of diseases and insect pests, which should be prevented and controlled. Prevention and control of diseases and insect pests should be more important than control, spraying once every semimonthly, spraying time is about 9: 00 in the morning, about 4: 00 in the afternoon, the hot sun should not be sprayed at noon to prevent drug damage. How to grow lemon trees in potted plants? Culture methods of potted lemon trees

Nowadays, more and more people like to plant fruit trees at home. While watching the verdant leaves, they can also harvest fruit and get more with one stone. As one of the favorite fruits, lemon is naturally the first choice of indoor potted fruit trees, which is more ornamental than tall lemon trees. So, how to grow lemon trees in pots? The cultivation methods of potted lemon trees are introduced as follows.

Light and temperature

Lemon is a light-loving plant, but if the sun is too strong, it will grow poorly. Generally, at noon, the annual average temperature for plant replacement is more than 15 ℃, and the optimum growth temperature is 23 ℃ to 29 ℃. If the plant stops growing at more than 35 ℃, it will be damaged by freezing at-2 ℃. Lemons generally do not need to cool down in summer, enter the room before Frosts Descent and leave the room after Qingming Festival, which can survive the winter safely.

2. Reasonable pruning

There are two reasons for potted lemon pruning, one is that the pots are small, the soil is less, and the nutrients provided are limited, which can not meet the needs of lemon growth, and must be pruned; second, through shaping and pruning, the rational distribution of nutrients in the tree is adjusted, so that the limited nutrients are concentrated to supply buds and leaves to form more fruiting branches, so as to achieve full branches of flowers and fruits. Potted lemon must be pruned before spring shoot germination. firstly, withered branches, diseased branches, overgrown branches, introverted branches, cross branches, sprouting branches and so on should be removed. Leave 4 or 5 full buds for strong branches and 2 or 3 buds for weak branches to promote more robust spring shoots on each branch. After the spring shoot grows evenly, in order to control its overgrowth, light cutting can be carried out to cut off 3 or 4 nodes of the shoot. The new shoots will be plucked when there are 6-8 knots, in order to induce more summer shoots.

Third, "buckle water" before flowering

In order to prevent the summer shoot from growing too much, and at the same time accumulate nutrients and promote the formation of flower buds, potted lemons were watered before the End of Heat. The specific approach is that the water supply to potted lemons gradually decreased in the first ten days of the End of Heat; the water supply was stopped in the first five days, and the water in the basin soil evaporated in large quantities and dried in the basin soil; because of the lack of water in the root system, the branches and leaves lost water, and the leaves withered and curled. In order to prevent leaf dehydration, water can be sprayed to the leaf surface in the morning and evening, and a small amount of water can also be sprayed to the basin soil, so that the lemon is under the condition of drought and not dying, its axillary buds are expanding day by day, and the bud color changes from green to white. when most of the axillary buds turn from green to white, the "buckle water" to promote flowers is successful. At this time, it is necessary to restore the water supply to potted lemons in time.

IV. Rational fertilization

Lemon like fertilizer should be more thin fertilizer at ordinary times. The plants were treated with rotten liquid fertilizer before sprouting, and then every 7-10 days with liquid fertilizer dominated by nitrogen fertilizer to promote the growth of branches and leaves and multiple spring shoots. After picking the heart every time, it is necessary to apply fertilizer in time to make the branches mature earlier. Lemon growth period, can sprinkle some cake fertilizer in the basin, so that each watering there are some fertilizer infiltrated into the soil to enhance fertility. After entering autumn, fertilization is reduced to avoid overnutrition of plants, promote autumn shoots, and compete with fruits for nutrients, resulting in fruit drop.

Fifth, turn the basin

Potted lemon due to the lack of potted soil, nutrition supply is very limited, after many years, the lack of soil fertility, lemon will be weak year by year, less blossom, less fruit. In order to keep the lemon blossom and bear fruit year after year, the pot must be turned. The best time to turn the basin is half a month before the lemon sprouts. Before turning the basin, first prepare a basin larger than the original basin, remove the lemon from the basin, do not break the mud mass, cut off the surface soil 1 or 2 cm thick along the mud mass, cut off the withered root and rotten root, and cut off the soil 1 cm thick at the bottom of the mud mass, remove the tiles trapped in the original basin bottom mat in the soil. The drainage hole of the new basin is laid with tiles, first lay a drainage layer of 2 or 3 cm thick, and then lay a layer of nutrient-rich culture soil 4 or 5 cm thick, which is mixed with a small amount of calcium superphosphate. Then put the lemon mud into the basin, fill the culture soil around to the basin mouth, slightly compact the basin soil, pour enough fixed root water, put it in a ventilated and semi-shaded place, and put it back to the same place a week later for daily management.

VI. Change the basin and soil

Potted lemons must be turned over to change soil from March to April in spring. If the flowerpot is too small, you can change the adaptive flowerpot, if the flowerpot is still suitable, the original pot can be replaced with new soil, and the bottom fertilizer should be applied when changing the pot.

[conclusion] pruning, fertilizing and turning pots are indispensable links in the process of potted lemon trees, which directly affect the growth and appreciation of lemon trees. Above, I introduce the cultivation methods of potted lemon trees. I hope it can be helpful to you!
