Antifreeze for Prunus armeniaca L flowers and fruits

Abstract

The invention discloses a flower and fruit anti-freezing agent of kernel apricot, the flower and fruit anti-freezing agent of the kernel apricot is mixed by abscisic acid, brassinolide, cerous nitrate and water, wherein, the concentration of abscisic acid is 10 mg / L, the concentration of brassinolide is 1.6mg / L, and the concentration of cerous nitrate is 0.8mg / L. The invention has advantages of reasonable medicament compatibility, high medicament utilization rate, obviously reduced percentage of frosted flower and increased percentage of fertile fruit of almond-apricot. The plant using the medicament has the reduced percentage of frosted flower by 38 percent-66 percent compare with clear water and has the increased percentage of fertile fruit by 103.8 percent compare with clear water. The materials used by the invention has advantages of high permeability, internal absorption, high efficiency, broad spectrum, low toxicity and safety, low making cost and convenient use. The invention is suitable for various kernel apricots, and other fruit trees can also take the invention for reference.

Description

technical field [0001] The invention belongs to the technical field of antifreeze agents for fruit trees, and relates to an antifreeze agent for flowers and fruits, in particular to an antifreeze agent for apricot trees used for kernels, which is suitable for preventing freezing damage in the flower and fruit stage and improving the fruit setting rate of apricots used for kernels. Background technique [0002] Apricot tree for benevolence is an ideal tree species for mountain greening and increasing people's income, and has good economic, social and ecological benefits. Therefore, in the project of returning farmland to forests implemented by the state in recent years, apricots for kernels have been planted in a large area in northern my country, and large-scale production bases have been built in many areas. More than 10,000 mu. However, due to the early flowering of apricot for kernels, the late frost damage during the flowering period is serious, and the annual yield loss...

AI Technical Summary

Problems solved by technology

However, due to the early flowering of apricot for kernels, the late frost damage during the flowering period is serious, and the annual yield loss due to freezing damage in the flowering and fruiting period is about 30%-40%, which has become a limiting factor restricting the development of the apricot industry for kernels

[0003] In the known technology, the existing medicaments for preventing freezing damage in the flowering and fruiting stages of kernel apricots include Bishi and Tianda-2116, but Bishi and Tianda-2116 have unstable effects on the cold resistance of apricots for kernels, and another On the one hand, due to the unique biological characteristics of apricot trees that bloom first and then grow leaves, these drugs are applied by crown spraying in the early flowering stage. Due to the poor ability of the tree to absorb the drugs at this stage, the loss of the drugs and Reduced antifreeze effect
