Anti-drought fertilizer special for wheat and use method thereof

Abstract

The invention relates to the technical field of fertilizers, in particular to an anti-drought fertilizer special for wheat and a use method thereof, and aims to provide a special fertilizer that is specific for dry areas in north China, can improve the drought and lodging resistant capability of wheat, reduce pest and disease damage, and finally ensure wheat yield. Foliar-fertilizers choline chloride and calcium hydrogen superphosphate are sprayed to improve photosynthesis and promote dry matter accumulation, so that distribution of dry matters into sink organ is in a coordinated source-sink relationship, the distribution proportion of a photosynthetic product into a sink organ increases, the retention amount of nonstructural carbohydrate in stems and leaves decreases, thus actively improving the sink capacity and promoting movement of a lot of source leaf photosynthetic products into grains.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special drought-resistant fertilizer for wheat and its application method. Background technique [0002] Wheat is a general term for wheat plants, and it is a gramineous plant widely planted all over the world. It originated in the Fertile Crescent (Levant) region of the Middle East and is one of the earliest cultivated crops in the world. The caryopsis of wheat is the staple food of human beings. One, after being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods; after fermentation, it can be made into beer, alcohol, vodka, or biofuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C, etc. [0003] In most non-irrigated planting areas in the north, winter wheat is the main crop, and its growth stages are divided into sowing, emergence, overwintering, greenin...

AI Technical Summary

Problems solved by technology

[0003] In most non-irrigated planting areas in the north, winter wheat is the main crop, and its growth stages are divided into sowing, emergence, overwintering, greening, jointing, earing, flowering, filling, and milk ripening; sowing begins in October, and wheat enters the field from mid-December to the end of January. During the wintering period, the greens gradually turn in the middle and late February, and the jointing stage gradually enters the first ten days of April. In May, the growth of winter wheat enters the poplar filling period, which requires the most water. However, in most non-irrigated planting areas in the north, the spring rain has passed at this time. The summer rainy season generally occurs from July to August. For winter wheat, the demand for water is high at this time, but the weather is not enough to provide the required water under natural conditions, resulting in reduced production and reduced economic benefits.
