Do you need to fertilize the longan after picking it First, can you fertilize the longan when it blo

Lychee is planted and survives until it bears fruit, and it is a young tree. At this time, the main goal of management is to rapidly expand the canopy and lay the foundation for early fruiting and good yields. Therefore, in terms of management measures, it is necessary to strengthen soil management, cultivate a well-developed root system, and promote a large number of branches to grow and form a high-yield tree.

However, due to the young root system, it is very sensitive to fertilizers. Therefore, fertilization should grasp the principle of small, frequent, timely and frequent application, thin application, fertilizer and water application. Lychee seedlings are generally plucked 4-5 times, and each time before the shoots, it is the rooting period.

When the roots are rooted, there are many fine roots and the fertilizer is absorbed quickly, so it is the best time to apply fertilizer before each shoot. 3 years after planting, fertilize more than 6 times a year; After 3 years, as the root system and canopy expand, the fertilizer can be gradually thickened, and the frequency can be reduced year by year. Fertilization is better to open a 20-25 cm deep annular furrow.

The furrow should be 15 cm away from the fibrous roots, this fertilization method can induce the root system to expand outward, and can continuously renew and germinate new roots. The amount of EV bio-organic fertilizer applied to each plant is 2-3 kg.

Lychee enters the full fruiting period 20-30 years after planting. During this period, the root expansion gradually reaches its maximum, the nutrient level increases, and the yield also increases year by year, thus depleting a large amount of nutrients. Improper management of soil, fertilizer and water during such periods not only tends to produce large and small annual fruiting, but also accelerates the aging of trees due to the decrease in nutrient accumulation levels and reduced vegetative growth.

The fruiting mother branch of lychee is mainly autumn shoots, such as autumn shoots are many and strong, which is the key to overcoming the phenomenon of lychee size and ensuring the annual yield, so it is necessary to apply heavy fertilizer once after fruit picking, and appropriate irrigation, so that the plant can quickly recover the tree potential, and strive for the new shoots to be extracted in August and September, so as to provide more fruiting mother branches for the second year's bumper yield, which can promote the differentiation of flower buds, which is the key measure to ensure a bumper harvest every year. The specific method is to loosen the soil 10 cm deep around the roots of the tree, apply 5-10 kg of Tianwu EV bio-organic fertilizer to the plant, and cover it with a thin layer of soil after application.

Longan flowering can be right or wrong, and during the flowering period of longan, foliar fertilizer can be sprayed on the leaves to supplement nutrients, so as to improve the fruit setting rate of longan. In the flowering period of longan, it is necessary to do a good job of thinning flowers and buds to improve the quality of longan. In addition, a colony of bees can be cultivated around the flowers during the longan flowering period to improve the speed and quality of pollination.

Longan flowering can be fertilized, longan needs sufficient nutrients during the flowering period, you can spray leaf fertilizer on the longan leaves to supplement nutrients, so that the leaves become more dense green, so as to better carry out photosynthesis and improve the fruit setting rate. And it can also be sprayed with potassium dihydrogen phosphate solution for 3 or 4 times in a row for longan trees to supplement nutrition.

After the flowering of longan, it is necessary to strengthen the pollination work, if the flowers are in rainy weather during the full flowering period, it is not conducive to pollination, and it needs to be supplemented by shaking the flowers to assist the plants for pollination. A colony of bees can also be raised around the longan tree to assist in differential pollination to improve the speed and quality of pollination.

In the flowering period of longan, it is also necessary to do a good job of thinning flowers and buds, which can reduce the number of flowers, thereby improving the quality of flowering. When the flower spike is too long, the excessively long part needs to be truncated. The tip of the nose also needs to prune off the overly dense flowers, residual flowers, and weak flowers in a false state, and only the full flowers should be retained.

Note that it is not advisable to spray pesticides during the flowering period of longan, otherwise it will cause insect pests such as beetles. It is recommended to spray insect mite ba emulsifiable concentrate with water 2000 times in time to reduce the breeding of pests and diseases, so as to improve the yield of longan.

Longan can not be fertilized when flowering, at this time to supplement nutrients, will affect the quality of flowers, reduce the fruiting rate, can be before flowering, apply a fertilizer to protect flowers and fruits, to promote the opening of flowers, in addition to the longan tree after flowering, to shake the branches, let the flowers complete the pollination work, and to cut off the branches and leaves that are weak and dense flowers, so that the longan Yunshen tree grows healthily.

If you want to apply fertilizer to the plant, you can choose to do it during the flowering period or after fruiting, too much fertilizer during the flowering period will cause the longan tree to grow poorly.

After the longan tree blooms, it needs to help it complete the pollination work, and shake the branches vigorously to let the pollen in the stamens fall off, and pollination is best done quietly in the sunny afternoon, if the weather is rainy, it will cause the dragon to lose the eye tree to bloom.

After the longan tree blooms, it is necessary to use scissors to cut off the thick, thin and diseased branches and flowers on the plant to provide ventilation and light transmission between the branches and keep the longan tree in a healthy growth state.

During the flowering period of the longan tree, it is necessary to ensure sufficient sunlight, the more sufficient the light, the better the growth of the flowers, which is conducive to improving the fruit yield, but when the noon light is too strong, it is necessary to use a parasol to prevent the longan tree from being burned.

When fertilizing longan trees, it is necessary to pay attention to the time of fertilization, the type of fertilizer, the principle of fertilization and the sequence of water and fertilizer. Fertilization 4-5 times a year, selected in the month, mainly compound fertilizer and organic fertilizer, adhering to the principle of thin fertilizer diligent application of appropriate amount, first fertilization and then watering to promote absorption.

1. Fertilization time

Longan seedlings are generally fertilized 4-5 times a year, the first time is fertilized in February to increase the differentiation of flower spikes, the second time is carried out in April to reduce the flower drop rate, the third time is carried out in June to promote the development of young fruits, the fourth time is in August, and the fifth time is in October, all in order to supplement nutrition.

2. Types of fertilizers

When fertilizing the longan tree, the fertilizer generally used is mainly chemical fertilizer and organic fertilizer, in the early stage, it is necessary to use cake fertilizer to break it and mix it into the soil as a base fertilizer, and use nitrogen fertilizer and organic fertilizer in the juvenile stage, and replace it with phosphorus and potassium compound fertilizer in the flowering and fruiting stage to promote flowers and fruits.

3. The principle of fertilization

Longan tree is a kind of plant that is not particularly strict in the demand for fertilizer, normal fertilization can meet the needs of its growth and development, fertilization should uphold the principle of thin fertilizer diligently, a small amount of many times to apply, and ensure that no raw fertilizer or thick fertilizer is used, so as not to cause fertilizer damage, and do not use spoilage fertilizer.

4. Water and fertilizer sequence

In the sequence of watering and fertilization, there is also a certain principle, watering should be after fertilization, because when fertilizing, there will be a part of the fertilizer splashed up or failed to penetrate into the soil layer, staying on the surface of the plant or the surface of the soil, resulting in salinization, so watering again can wash away these inorganic salts.

Summary. Kiss, longan fruiting trees are generally fertilized 4 5 times a year.

The first application was applied in February, mainly to increase the differentiation of flower spikes and increase the heading rate. The second application was applied in April, which was mainly to reduce flower drop, improve the fruiting rate of young fruits and promote the extraction of summer shoots. The third application was applied in late June to promote the development of young fruits, the enrichment of summer shoots, and the continued germination of new summer shoots. The fourth application is from the end of July to the beginning of August, which promotes the expansion, fullness and fullness of the young fruits, and the new summer shoots continue to be strong; The fifth application is applied in September and October, so that the tree body after fruit picking can be nourished and restored, so that the autumn shoots can grow healthily.

As a result, the longan tree needs to be fertilized several times.

Kiss, longan fruiting trees are generally fertilized 4 5 times a year. The first application was applied in February, mainly to increase the differentiation of flower spikes and increase the heading rate. The second application was applied in April, mainly to reduce flower fall, improve the fruiting rate of young fruits, and also have a certain effect on promoting the sale of silver in summer shoots. The third application was applied in late June to promote the development of young fruits, the enrichment of summer shoots, and the continued germination of new summer shoots. The fourth time was applied from the end of July to the beginning of August, to promote the expansion of young fruits at the banquet to be large, full and full, and the new summer shoots to continue to be strong; The fifth application is applied in September and October, so that the tree body after fruit picking can be nourished and restored, so that the autumn shoots can grow healthily.

Summary. Hello, you can't fertilize longan when it blooms!

Hello, you can't fertilize longan when it blooms!

Hello, fertilizing longan at the time of flowering will shorten the flowering period and affect the fruit. Longan is generally fertilized 3 times, the first time in the early stage of flowering, can promote the differentiation of flower buds, the development of flower spikes, reduce the fall of flowers and the fall of the grinding and burying fruits. The second application at the young fruit stage can promote fruit growth and reduce physiological fruit drop.

The third application of ear manure before and after fruit picking can restore the vitality of the tree.

Hello dear, I am glad that your question is good Yes, longan trees can be fertilized. Liquid organic fertilizers, such as liquid compost liquid, organic herbicides, etc., can be applied before flowering, and the abundance of nutrients can promote flowering. In addition, after flowering, nitrogen, phosphorus, potassium and other compound fertilizers can be applied regularly, and the core banquet finch can prolong the early flowering and make the flower color more vivid.

Longan can not be fertilized when flowering, at this time to supplement nutrients to attack the hand, will affect the quality of flowers, reduce the fruiting rate, can be before flowering, apply a fertilizer to protect flowers and fruits, promote the opening of flowers, in addition to the longan tree after flowering, to shake the branches, so that the flowers are finished into pollination work, and to cut off the branches and leaves that are weak and dense with flowers, so that the longan tree grows healthily.
