Problems solved by technology

[0003] Wheat is the second largest grain crop in China. It has a long growth period. It is sown in autumn, winter and spring, and harvested in summer. The growth period spans 2 years, including four seasons of spring, summer, autumn and winter. After experiencing low temperature stress such as cold current and late spring, and almost all winter wheat planting areas have chilling injury and freezing injury, which greatly affects the quality and yield stability of wheat production, and seriously threatens food security. At present, low temperature freezing injury has become the largest natural problem in China's wheat production. One of the disasters; therefore, enhancing the ability of wheat to resist low temperature and freezing damage has important practical significance and applica

Embodiment 1

[0011] In this embodiment, the low-molecular weight enteromorpha polysaccharide with a molecular weight of 1k-50kDa is dissolved in distilled water, so that the concentration of enteromorpha polysaccharide is 100-1000mg / L, and the anti-low temperature regulator A is obtained; or in the anti-low temperature regulator A, add Any one or more of salicylic acid, brassinolide, betaine and / or spermidine, the specific concentration is salicylic acid 0mg / L or 100-200mg / L, brassinolide 0mg / L or 0.01- 0.1mg / L, betaine 0mg / L or 100-1000mg / L, spermidine 0mg / L or 10-100mg / L, make anti-low temperature regulator B; or to anti-low temperature regulator A or anti-low temperature regulation Surfactant is added respectively in agent B, and surfactant is selected the mixture of one or more in Tween series, Span series, OP series and / or NP series, makes surfactant concentration be 1-20g / L, The anti-low temperature regulator C is obtained; the above-mentioned anti-low temperature regulator A, anti-l...

Embodiment 2

[0013] In this example, 100 mg of Enteromorpha polysaccharide with a molecular weight of 5 kDa was weighed and dissolved in 800 ml of distilled water, then 1000 mg of Tween-20 was added and stirred evenly, and finally the volume was adjusted to 1 L with distilled water, and the wheat cold resistance regulator was obtained after stirring evenly .

Embodiment 3

[0015] In this embodiment, first weigh 100 mg of Enteromorpha polysaccharide with a molecular weight of 5 kDa and dissolve it in 800 ml of distilled water to obtain an Enteromorpha polysaccharide solution, then weigh 100 mg of salicylic acid and dissolve it in the above-mentioned Enteromorpha polysaccharide solution, and then add 1000 mg of Tween-20 and stir evenly, and finally make the volume to 1L with distilled water, and stir well to prepare the wheat cold resistance modifier.

Abstract

The invention belongs to the technical field of plant growth regulators, and relates to a wheat cold resistance regulating agent. The wheat cold resistance regulating agent comprises the specific components of 100-1000 mg/L of enteromorpha polysaccharide, 0 mg/L or 100-200 mg/L of ortho-hydroxybenzoic acid, 0 mg/L or 0.01-0.1 mg/L of brassinolide, 0 mg/L or 100-1000 mg/L of glycine betaine, 0 mg/L or 10-100 mg/L of spermidine, 0 mg/L or 1000-20000 mg/L of surfactant and water as a solvent, wherein the enteromorpha polysaccharide is low-molecule weight enteromorpha polysaccharide with a molecule weight of 1 k-50 kDa; and the related surfactant is one or a mixture of Tween series, Span series, OP series and/or NP series. A use method of the wheat cold resistance regulating agent comprises the step of spraying/irrigating a wheat seedling, or planting after soaking a wheat seed for 6-12 h. The wheat cold resistance regulating agent is simple in components, easily available in raw materials, low in cost, remarkable in effect and environmentally friendly.

Description

Technical field: [0001] The invention belongs to the technical field of plant growth regulators, and relates to a wheat cold-resistant regulator. One or more compound preparations can effectively improve the cold resistance of wheat. Background technique: [0002] Enteromorpha is a large-scale economical green algae belonging to the genus Enteromorpha genus Ulvaceae of Chlorophyta Ulvaceae. The algae are grass green and mainly grow in the intertidal zone. It can grow every year, and there are a large number of distributions along the coast of my country; however, in recent years, large-scale sudden green tides of Enteromorpha have continuously broken out in my country's coastal waters, causing great pollution to the sea environment. Most of the common methods of using Enteromorpha at present are Burying retting or drying and crushing into feed has low technical content and low utilization efficiency, resulting in serious waste of resources. Therefore, it is necessary to devel...
