Want to make litchi fruit thicker, what medicine can be sprayed to achieve this effect?

Litchi grows bigger and bigger, and the effect of yield is difficult to calculate. Small fruit, fruit shape, abortion fruit, all kinds of plantations are very headache.

Do you know how to manage the durability of litchi when planting? How to compare litchi insurance? I want to know about it!

The peak rate of litchi is mainly affected by litchi, climate, flowers, quantity, nutritional level and hormone level, and litchi will have three obvious physiological decorative peaks.

The first physiological decline after breastfeeding Poria cocos is usually 6- 10 days, which usually leads to poor fertilization; The second kind of physiological decoration refers to 15-25 days after Xie Jiehua, because the old organs lead to Cordyceps.

In order to promote the protection of litchi, we must pay attention to the promotion of litchi, improve the fruit setting rate of litchi, put bees in the orchard, improve the fruit setting rate, cut it short, reduce the consumption of seasonings and nutrients, and improve the fruit setting rate.

When litchi blossoms, the rain flows, and it is dry all day, flowering, litchi period, rain and no wind, so flower treatment should be prevented; If you encounter hot and dry weather, spray it for a long time to increase air humidity and prevent high concentration of nectar from interfering with insect powder.

It is also necessary to supplement the nutrients needed for litchi growth. In terms of time, litchi leaves, litchi leaves, the second physiological and determined fruit (soybean size) after node, the second physiological decline, and after the third physiological decline, the leaves were sprayed with Jintai for 2-3 times, with an interval of 7- 10 day.

In the process of litchi cultivation, another difficulty besides flower protection is to prevent the former effect and cracks. Some litchi varieties, such as glutinous rice, are rumored to have a thin, elastic and cushioned skin, which contains a small amount of peeling strength and cannot crack fruit for rapid growth and calendering. Generally, the annual cracking rate reaches 20%-40%, and the rain is unbalanced during the fruit development period, or the cracking rate is as high as 70% in typhoon rainstorm and frequent rainfall, and even as high as 90% in individual plants.

Litchi fruit cracking is closely related to water and fertilizer management, climate conditions, nutrition level, hormone level, fruit development, respiratory metabolism, varieties and so on. Genital features, easy to fracture, eccentric structure, reasonable effect sensitivity.

Peeling is thin, with cracks (between cracks) and thin inside. It is difficult to peel both at home and abroad, which makes peeling elasticity, crack strength and peeling strength low and grows rapidly in fruits without cracks and stones. These characteristic peels are the main reasons for fruit cracking.

In addition, the content of calcium is an important factor affecting the peeling strength. The results of normal pericarp and inspection of nutritional components of pericarp showed that the calcium content in pericarp was significantly lower than that in normal pericarp. Because calcium enhances the strength of cell wall by influencing calcium, thus enhancing the toughness of cell wall, it is closely related to cutting. The existence of boron is beneficial to calcium absorption, calcium movement, calcium movement, calcium movement, calcium movement, calcium movement, calcium movement, sugar and endogenous hormones movement. It can be seen that maintaining high calcium and boron content may help to reduce the premium of litchi.
