Prunus armeniaca sibirica late frost-avoiding method, late frost-avoiding solution and preparation method thereof

Abstract

The invention discloses a prunus armeniaca sibirica late frost-avoiding method, a late frost-avoiding solution and a preparation method thereof. The late frost-avoiding solution, on the basis of 1000 ml, includes 0.5-3 g of daminozide, 20-25 ml of glycerol, 20-30 ml of sorbic enol and 5-10 ml of a polyvinyl alcohol solution, wherein mass percentage of polyvinyl alcohol in the polyvinyl alcohol solution is 5-15 wt%, the polyvinyl alcohol is PVA 17-88 or PVA 17-92. In the invention, by means of large quantity of the prunus armeniaca sibirica treated by different growth regulators, different concentrations and different time, influence on blossom delaying of the prunus armeniaca sibirica due to the prepared solution is researched, thereby providing a solution for avoiding the late frost in the prunus armeniaca sibirica, wherein the solution is applied in late frost avoiding of the prunus armeniaca sibirica and provides excellent basis on high-yield cultivation technology of the prunus armeniaca sibirica. By means of the solution, the blossom time of the prunus armeniaca sibiric is delayed by 15 days at most.

Description

technical field [0001] The invention relates to the technical field of using apricot trees for kernels to avoid night frost. More specifically, it relates to a method of apricot night cream for kernels, a night cream solution and a preparation method thereof. Background technique [0002] Apricot for kernels (Prunusarmeniaca×sibirica) is a deciduous tree of Rosaceae, which is an interspecific hybrid between Siberian apricot (P.sibiricaLinn.) and apricot (P.armeniacaLinn.), and is divided into sweet almond and bitter almond. Apricot is one of the six largest dried fruits in the world, and it is also an important woody oil tree species. Apricot for kernels has strong adaptability, strong drought resistance, cold resistance, and wind and sand resistance, can significantly improve the ecological environment, and has remarkable ecological benefits. It is the main tree species in the "Three North" shelterbelts. Almond has high food value and medicinal value. Sweet almond has a b...

AI Technical Summary

Problems solved by technology

Many scholars at home and abroad have done a lot of research on the cultivation techniques of kernel apricots to avoid late frost by delaying flowering, such as irrigation, water spraying, whitewashing, lime spraying, sunshade net coverage, etc., but due to the above conventional Cultivation technical measures, delayed flowering time is short (about 3d), and time-consuming, laborious, difficult to promote in production, so there is no effective cultivation measure to solve the hazard of late frost in kernel apricot
