Fruit tree evaporation-reducing agent

Abstract

The invention discloses an evaporation reducing agent for fruit trees. The evaporation reducing agent is prepared by 4 to 6 portions of film forming agent, 0.05 to 0.15 portion of anti-freezing agent, and 0.2 to 0.4 portion of liquid film curing agent, can be widely applied to garden plants such as fruit trees and the like to restrain evaporation, water loss and transplant, and has obvious evaporation reducing effect compared with the existing evaporation reducing agent; the evaporation reducing effect can last more than 30 days, and the average evaporation rate can be reduced by 16.98 to 29.74 percent; the evaporation reducing agent does not need to be dissolved by warm water, urea is dissolved in polyvinyl alcohol liquid to form mixed liquid, and then calcium chloride is dissolved in the mixed liquid after dilution during use; the evaporation reducing agent can be sprayed to the fruit trees, has simple and convenient operation, can correspondingly reduce usage time, can lower generation cost greatly, is easily accepted by fruit growers, has long available period, and forms a transparent film after the evaporation reducing agent is used to reduce ineffective water loss of blades;the average stomata conductance can be reduced by 9.96 percent; and the evaporation reducing agent has double evaporation reducing effects, can be directly absorbed by the plant blades after application, can provide nutrient required by growth for the plants, can improve dry substance content of the blades, has no adverse reaction to the plants, and has remarkable social and economic benefits andecological environment benefit.

Description

technical field [0001] The invention relates to an anti-transpiration agent, in particular to an anti-transpiration agent capable of reducing water loss from stems and leaves of fruit trees. Background technique [0002] Inhibiting the transpiration and dehydration of plant leaves is one of the important measures to save water in production. In recent years, many scholars have conducted a lot of research on it and used chemical agents to reduce plant transpiration. Among them, there are many research reports on plant anti-transpiration agents, and some of them have become commercial products and have been applied. Among them, the representative products are: Hanlu Zhibao finished product composed of powder + liquid formulations produced by Beijing Green Singularity Technology Development Co., Ltd. The market price is relatively high at 150 yuan / kg. The water temperature has certain requirements, and the dissolution time is long. In order to prevent the nozzle from clogging,...

Problems solved by technology

Among them, the representative products are: Hanlu Zhibao finished product composed of powder + liquid formulations produced by Beijing Green Singularity Technology Development Co., Ltd. The market price is relatively high, 150 yuan / kg. The water temperature has certain requirements, and the dissolution time is long. In order to prevent clogging of the nozzle, it is necessary to add a filter to filter when spraying; the anti-transpiration protection agent of Beijing Jinyuanyi Ecological Engineering Technology Center has two dosage forms, dry agent and liquid. The liquid dosage form can be used directly after being diluted 15-20 times; the dry dosage form can be used after being diluted 400 times with water and left for 48 hours. Compared with the liquid dosage form, the use cost is higher and the operation is inconvenient;

[0003] In short, there are many related researches at home and abroad, and many are applied to production. They each have certain anti-transpiration and yield-increasing effects, but some of them have few resources or high costs, some have large application amounts or single effects, and some It has an impact on the environment, which hinders large-scale promotion to a certain extent, and its application range is limited to field crops such as winter wheat, corn, rice, sorghum, soybeans, peanuts, cotton, sugar beets, shouji and chingrass, and landscaping Engineering, that is, the anti-transpiration of flowers and seedlings before transplanting, during transportation and after transplanting, and there are generally disadvantages that the anti-transpiration effect is not obvious
