Problems solved by technology

The shortcoming of above-mentioned measure is: measure (1), needs long-term comprehensive cultivation management, and cycle is long, and the influence factor that is subjected to in the fruit tree growth process is many; Measure (2) mainly is to increase soil water content, and it is slower to influence aboveground part; Measure (3) is a passive measure, with a large amount of labor, difficult operation and polluting the environment; measure (4) requires too high cost of film covering
Hormone antifreeze (such as "Bihu" of Agfrey Agriculture and Forestry Environmental Biotechnology Co., Ltd., Germany) is a growth promoter, and its main components include natural gibberellin, indole acetic acid, brassinolide and other plant hormones , through systemic induction, multiple activities of plants can be activated, so that the plants will flourish, the roots will develop, and the stress resistance of the plants will be significantly improved. Leggy growth (i.e. the excessive growth of stems and leaves produced by crops), leggy growth will cause excessive vegetative growth of crops, decreased resistance, and poor flower and fruit setting; 2. Tests have shown that after spraying hormone antifreeze, plants can resist temperatures of -2~-1℃, the antifreeze effect is average
The main components of foliar fertilizers are phosphorus and potassium fertilizers and amino acid leaf fertilizers. The antifreeze mechanism is to promote the growth of crop leaves, rely on photosynthesis of leaves to produce sugars, increase the concentration of cell fluid, prevent cell dehydration, and improve plant frost resistance. Its disadvantages The reason is that the antifreeze mechanism is relatively simple, and the antifreeze effect is unstable. After spraying the foliar fertilizer antifreeze, the plants can resist the temperature of 0°C, and the effect is not good.

Embodiment 1

[0024] Embodiment 1: Tomato freezing injury test

[0025] 1. Experimental design: Select an experimental field, plant tomatoes in the experimental field, and spray the tomatoes with six kinds of reagents. The six reagents are crop antifreeze agent 1, crop antifreeze agent 2, crop antifreeze agent 3, Bihuo ("bihuo" produced by Germany Agfly Agriculture and Forestry Environmental Biotechnology Co., Ltd.), amino acid foliar fertilizer (chosen Shandong Tianda Biopharmaceutical Co., Ltd. "Tianda-2116"), clear water, and the specific components of each reagent are as follows:

[0026] Antifreeze agent for crops 1: Take 18 parts of polyethylene glycol, 15 parts of N,O-carboxymethyl chitosan, 2 parts of soybean hydrolyzed amino acid, 2 parts of calcium lactate, 2 parts of potassium dihydrogen phosphate, 6-benzylaminoadenine 0.02 parts, 0.35 parts of brassinolide, 0.04 parts of diethyl hexanoate, and 0.01 parts of abscisic acid were dissolved in 1000 parts of distilled water. The mas...

Embodiment 2

[0044] Embodiment 2: sweet pepper freezing injury test

[0045] Adopt and embodiment 1 same test design, test process, test reagent to process sweet pepper test field (promptly change sweet pepper from tomato into, all the other test steps are identical), on January 28, 2016, carry out to each processing All individual plants were field surveyed. For the survey indicators, please refer to the "Crop Freezing Injury Grade Index Table". ).

[0046] Bell Pepper Frozen Injury Investigation Result Table

[0047]

[0048] Investigation result shows: the freezing injury index of the crop antifreeze disclosed by the present invention (crop antifreeze 1, crop antifreeze 2 and crop antifreeze 3) is all<50%, compared with Bihu (56.17%), amino acid foliar fertilizer (64.08 %), the freezing damage index of the antifreeze agent for crops of the present invention is significantly lower.

Embodiment 3

[0049] Embodiment 3: Cauliflower frost damage test

[0050] Adopt and embodiment 1 same test design, test process, test reagent to process sweet pepper test field (promptly change cauliflower into cauliflower by tomato, all the other test steps are exactly the same), on January 28, 2016, carry out all to each processing Single plant field investigation. Survey index "Crop Freezing Injury Grade Index Table", freezing injury index = ∑ [number of individual plants at all levels × corresponding series] × / (total number of surveyed plants × highest grading series), the survey results are shown in the table below (Cauliflower Freeze Injury Survey Results Table) .

Abstract

The invention belongs to the technical field of crop anti-freezing, and discloses an anti-freezing agent for crops.The anti-freezing agent is prepared from, by mass, 15-20 parts of polyethylene glycol, 10-15 parts of N,O-carboxymethyl chitosan, 1-2 parts of soybean hydrolyzed amino acid, 1-3 parts of calcium lactate, 1-3 parts of monopotassium phosphate, 0.01-0.03 part of 6-benzylamino adenine, 0.2-0.4 part of brassin, 0.02-0.04 part of diethyl aminoethyl hexanoate, 0.01-0.03 part of abscisic acid and 1000 parts of distilled water.The anti-freezing agent is good in anti-freezing effect and cannot cause excessive growth of plants.

Description

technical field [0001] The invention belongs to the technical field of plant antifreeze. Background technique [0002] Autumn and winter crops in the south (especially autumn and winter vegetables) are the main source of market supply in the north in winter and spring, and the price of autumn and winter crops is higher, which promotes the economic development of "agriculture, rural areas and farmers" in the south. [0003] Most of the dominant varieties of crops planted in autumn and winter in the south are warm-loving, but autumn and winter in the south (December to January of the next year) are low-temperature weather, and the average low temperature in the south is about -3°C, which makes it very easy for crops to suffer from freezing damage (such as Solanaceous vegetables will experience low temperature barriers if they are lower than 5°C for a long time, and they will suffer from freezing damage if they are lower than 1°C), which will seriously reduce the yield of crops...
