Problems solved by technology

[0010] Still another object of the present invention is to provide a kind of antifreeze agent for wheat in the application of foliage spraying at the seedling stage and booting stage of winter wheat. Through the verification of field plot experiments, it solves the problem of leaf damage and nutrient loss caused by low temperature in the seedling stage of wheat. Problems such as insufficient absorption, stunted growth, weak seedlings, diseased seedlings and other technical problems have greatly improved the yield of wheat

Embodiment 1

[0042] 1, a kind of antifreeze agent that is suitable for wheat, it is made by the mass concentration of following raw material:

[0043]

[0044] A preparation method suitable for wheat antifreeze, the steps are:

[0045] A, first utilize ethanol to dissolve brassin;

[0046] B, ammonium sulfate, EDTA-Zn, chitosan and proline are dissolved in 400mL water;

[0047] C, potassium dihydrogen phosphate, potassium sulfate and glycerin are dissolved in 400mL water again;

[0048] D. Finally, mix the mixture in the steps ABC, mix evenly, and set the volume to 1 L to obtain the wheat antifreeze.

[0049] According to the production volume, it can be multiplied by the multiple of the raw materials used.

[0050] The preparation method is simple; the nutrient distribution ratio of the raw materials is reasonable, and the properties among the components are stable; the environment is friendly, the ecology is safe, and there is no environmental pollution problem; and it is easy to p...

Embodiment 9

[0057] A kind of antifreeze suitable for wheat is applied in foliage spraying at the booting stage. In April 2018, a plot test was carried out in the field. The application process is as follows:

[0058] At the beginning of April 2018, the Meteorological Department issued a cold wave warning, and sprayed antifreeze on April 6, 2018. The wheat damage was investigated on the second and seventh days after application, and the yield was harvested at the mature stage.

[0059] The survey found that there was no significant difference between the treatments on the second day after spraying, and the wheat growth was basically normal; the survey on the seventh day found that the top and middle edges of wheat leaves without antifreeze were dry and curled, showing obvious symptoms of frost damage, while the leaves sprayed The urea treatment was more severe, and the wheat growth was normal in the spraying antifreeze treatment, and only the top of the leaves had symptoms of freezing damag...

Abstract

The invention discloses antifreeze suitable for wheat and application thereof the antifreeze. The antifreeze is prepared from a certain proportion of ammonium sulfate, potassium dihydrogen phosphate,potassium sulfate, EDTA-Zn, chitosan oligosaccharide, proline, brassin and glycerol and prepared through the steps: A, the brassinrutin is dissolved through ethanol firstly; B, the ammonium sulfate, the EDTA-Zn, the chitosan oligosaccharide and the proline are dissolved in 400 mL of of water; and C, then the potassium dihydrogen phosphate, the potassium sulfate and the glycerol are dissolved into400 mL of of water, finally the three kinds of dissolved matter are mixed, the constant volume is 1 L, and thus the antifreeze suitable for the wheat is obtained. A formula is reasonable, using is convenienteasy, the physical and chemical properties of raw materials are utilized, the nutrient formula is reasonable, and the zinc element is added; the raw materials are safe and nontoxic, so that food safety risks are avoided, the cold resistance of the winter wheat in North China can be effectively improved through product application, and the nutrient needs of the wheat in the critical period can be met; and through field verification, the cold resistance of the wheat is improved by leaf fertilizer, the uniformity of wheat grains can be further improved, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of foliar fertilizer, and more specifically relates to an antifreeze agent suitable for wheat, a preparation method of the wheat antifreeze agent, and an application of the wheat antifreeze agent on wheat. Background technique [0002] China is the world's largest producer and consumer of wheat, and its annual output accounts for about 17% of the world's total output. Therefore, the continuous development of wheat production is not only of great significance to ensuring the safety of domestic rations, but also affects international food prices to a certain extent. Please See: He Zhonghu, Zhuang Qiaosheng, Cheng Shunhe, etc. China's wheat industry development and technological progress [J]. Journal of Agricultural Sciences, 2018, 8(1): 99-106. [0003] The North China Plain is an important wheat production area in my country. In recent years, the extreme low temperature in early April and the continuous high ...
