Protective agent for relieving freezing damage to pears in flowering season

Abstract

The invention relates to a protective agent for relieving freezing damage to pears in a flowering season. Each part of agent comprises 180-270 thousand units of oxytetracycline or streptomycin, 1.1-1.6 grams of lycine, 0.08-0.12 gram of salicylic acid, 0.8-1.2 grams of borax, 40-60 milligrams of gibberellin, 0.18-0.21 gram of organosilicon, 2.5-3.6 grams of urea and 8-11 grams of white granulated sugar. Through the interaction of the raw materials, pear flowers are prevented from freezing damage. Thus, the protective agent has favorable antifreezing effect and achieves high fruit setting rate.

Description

technical field [0001] The invention relates to a protective agent, in particular to a protective agent for alleviating freezing damage in the flowering stage of pears. Background technique [0002] The planting area of ​​pear trees and pear production both occupy an important share in fruit production. Most of the pear producing areas have a continental monsoon climate. The temperature in spring is unstable, and low temperatures often occur, especially late frost damage is more common. Pear is a perennial plant with a long life cycle. Pear orchard is a complex artificial ecosystem, which is easily affected by natural soil fertility, ecological environment and climatic conditions. The low temperature in spring mainly includes disastrous weather such as frost, cold wave, and frost damage. The impact of spring frost on fruit trees is mainly late frost, also called spring frost, which is very harmful to pear tree flowering and fruit setting. The cold wave habit is called cold...

Problems solved by technology

In recent years, the climate has changed a lot, and natural disasters such as frost, cold wave, hail, rain, blizzard, strong wind, drought, and freezing damage often occur, which have a great impact on the production of pear trees. Therefore, the protective agent used to reduce the freezing damage of pears is An important forestry product, preventing pear blossoms from being frostbitten is an important link to ensure the production of pear trees. The existing methods for preventing pear blossoms from being frostbitten often adopt the following measures: reasonably build gardens and cultivate frost-resistant varieties; Decrease and delay the flowering period of fruit trees; smoke method, heating method, covering method, irrigation method, water spraying method, air mixing method, spray nutrient solution or chemical agents to prevent frost, delay flowering period; scientific management, strengthen tree vigor, reasonable water and fertilizer Management, etc., the above methods are labor-intensive, and some effects are unstable
