Fruit tree antifreeze blossom-protecting agent

Abstract

The invention discloses an agent for preventing fruit trees from freezing and protecting flowers, wherein the agent comprises the following raw materials (by weight ratio): cane sugar 20-70%, boracic acid 20-70%, table salt 5-40%, and gibberellin 0.5-4%.

Description

technical field [0001] The invention belongs to the technical field of frost prevention in flowering stage of fruit trees of crops, and relates to a frost prevention agent, in particular to an antifreeze flower preservation agent for fruit trees. Background technique [0002] Shaanxi apple production areas are mostly located in Weibei and Yan'an areas, which are located in the Loess Plateau in Northwest my country. The Loess Plateau has a good ecological foundation for the development of the apple industry: the altitude is between 800-1200m; the temperature difference between day and night is large, with a daily temperature difference of 11.8-16.6℃; Strong performance; the climate is dry, the air humidity is low, and the occurrence of diseases and insect pests is light. However, the Loess Plateau has a typical continental climate, with dry air, erratic climate, and frequent cold snaps in early spring. Apples often suffer from low-temperature frost during flowering, which se...

Problems solved by technology

[0013] (3) Comprehensive medicine: the medicine contains multiple effects, such as the domestic "Tianda-2116", which can increase the nutrition of fruit trees and increase the stability of plant cell membranes, but the antifreeze effect is unstable

Due to the lack of systematic research on the prevention of freezing damage during the flowering period, fruit farmers still use the old techniques of fumigation and watering in the 1960s and 1970s, and the results are not satisfactory.
