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) .
[0051] Cauliflower frost damage survey results table
[0052]
[0053]
[0054] Investigation results show: the freezing damage index of the crop antifreeze disclosed by the present invention (crop antifreeze 1, crop antifreeze 2 and crop antifreeze 3) is all<20%, compared with Bihu (20.28%), amino acid foliage...
