Problems solved by technology

Antifreeze has the effect of delaying the germination of flower buds and leaf buds of walnut trees, but the antifreeze effect on other fruit trees is limited, and once the concentration is not accurately grasped, plant germination may be strongly inhibited, and in severe cases, it may even lead to reduced production and disordered plant growth and development

Embodiment 1

[0038] 1. Preparation of nano liposome-like solution of plant cell resurrection agent:

[0039] 1) After dissolving 0.8 g of soy lecithin and 0.06 g of β-sitosterol with chloroform ultrasonically, they are de-dissolved under reduced pressure at 20-30℃ to obtain a smooth phospholipid film;

[0040] 2) Add 20 mg of seaweed polysaccharides, 20 mg of soybean peptides, and 10 mg of surfactant PVP-K15 to the phospholipid film, then add 20 ml of pH 7.0 phosphate buffer, and diffuse under ultrasonic conditions in a water bath. After ultrasonic diffusion, place it in a cell ultrafine pulverizer. Crush (working 2 s / gap 2 s, power 350 W, 20 min), then centrifuge the resulting product (5°C, 6000 r / min, 10 min) to remove the lower layer of impurities, and finally filter with 0.22 microporous membrane to obtain The filtrate is the nano liposome-like solution of plant cell resurrection agent.

[0041] 2. Preparation of the nano-capsule dispersion of calcium cyclamate:

[0042] 1) 1.0g of calcium he...

Embodiment 2

[0054] The antifreeze performance test was carried out on the environment-friendly antifreeze emulsions for fruit trees prepared in Example 1 and Comparative Examples 1 and 2. The red Fuji apple tree (tree age 8 years) in Zhaoyuan, Yantai was used as the test phase. Mid-to-late month) Weather forecast There will be frost forecast in the early morning of April 26 (only on the same day). The environment-friendly antifreeze emulsion for fruit trees prepared in Example 1, Comparative Examples 1 and 2 (15-20kg per 20g with water) is in April Spray the whole apple tree canopy around noon on the 25th (one antifreeze is used for every 100 trees); the lowest temperature from the night of April 25th to the morning of the 26th is -3.2℃. At noon on April 28th, every tree canopy and middle A total of 90 unfolded petals adjacent to the bottom, all flowers whose floral organs turn light brown or brown are injured flowers (if among 90, the injured flower ≤ 1 is regarded as unfrozen, 2 ≤ the inj...

Embodiment 3

[0060] The antifreeze performance test of the environmentally friendly antifreeze agent emulsion for fruit trees prepared in Example 1 and Comparative Examples 1 and 2 was carried out with pear trees (6 years old) in Laiyang, Yantai as the test phase. During the pear blossom period, the weather forecast 2015 There was a cooling forecast in the early morning of March 09, 2010. The environment-friendly antifreeze emulsion for fruit trees prepared in Example 1, Comparative Examples 1 and 2 (15-20 kg per 20g of water) was used to perform the whole pear tree around noon on March 03 Spraying (one type of antifreeze is used for every 100 trees); the lowest temperature from the night of March 08 to the morning of March 09 is -3.6°C, at noon on March 10, a total of 90 pear flowers adjacent to the top, middle and bottom of each tree , The flowers whose floral organs turn black or brown are injured flowers (if among 90 flowers, the injured flower ≤ 1 is regarded as unfrozen; 2 ≤ injured fl...

Abstract

The invention belongs to the technical field of antifreezing agents for fruit trees and specifically relates to an environment-friendly antifreezing agent for the fruit trees and a preparation methodof the antifreezing agent. The invention provides the environment-friendly antifreezing agent for the fruit trees and the preparation method thereof, aiming to overcome defects in the prior art. According to the preparation method, algal polysaccharides and plant-sourced small-molecule polypeptide are prepared into a nano-like lipidosome solution, prohexadione calcium is prepared into nano microcapsule dispersion liquid, and he environment-friendly anti-freezing agent for the fruit trees is formed through the nano-like lipidosome solution, the nano microcapsule dispersion liquid, glycerinum, vitamin E, sodium alginate, 50 wt% aqueous polyethyleneimine (PEI) solution and mannitol. The prepared antifreezing agent can achieve quick-acting and long-acting antifreezing effects, is applicable tomultiple economic crops, such as apple trees, tea, mulberries, strawberries, grapes and various flower and fruit seedlings, and has the antifreezing effect especially for flower buds, sprouts and leaves of the apple trees and the like.

Description

Technical field [0001] The invention belongs to the technical field of antifreeze agents for fruit trees, and specifically relates to an environment-friendly antifreeze agent for fruit trees and a preparation method thereof. Background technique [0002] North my country often encounters erratic temperature changes in the early spring, late autumn and early winter. Crops often suffer severe freezing damage due to sudden changes in weather and sharp drops in temperature, resulting in damage to the leaves and flowers of cash crops such as fruits and vegetables. At present, in agricultural production practice, in order to prevent plants from freezing damage, smoking or mulching is often used, but the smoking method produces a large amount of carbon monoxide and carbon dioxide, and the effect is very small; the mulching method is to cover crops such as hay, straw, and wheat straw. It has limitations and is limited to small-scale pastoral areas, and the cover needs to be removed later...
