Cold-proof agent for wheat late spring coldness

Abstract

The invention provides a cold-proof agent for wheat late spring coldness. The cold-proof agent comprises cane sugar and organic silicon. The cold-proof agent provided by the invention not only is simple in preparation method, but also is low in cost, and more importantly, the cold-proof effect of the cold-proof agent is equivalent to that of a relatively expensive cold-proof agent on the current market.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cold-proof agent for wheat in late spring. Background technique [0002] During the jointing stage of wheat, if the temperature suddenly drops to 0°C or below (commonly known as "cold in late spring"), it will cause great harm to wheat production. "Late spring cold" has become the main factor limiting the high and stable yield of winter wheat in Huanghuai region of my country. At present, there are many measures to deal with the "cold late spring", such as selecting varieties with strong stress resistance, staggering sowing according to the characteristics of different varieties, or applying some chemical control agents. Among them, spraying a certain concentration of antifreeze agent before / after the occurrence of chilling injury is an effective remedial measure, which can avoid the yield loss caused by low temperature to a certain extent.
