Preparation for promoting growth and development of wheat in weak light environment and preparation method thereof

Abstract

The invention relates to a preparation for promoting growth and development of wheat in a weak light environment and a preparation method thereof. The preparation comprises the following components in percentage by weight: 0.00001-0.00005% of brassinolide, 0.0001-0.0005% of 6-benzylaminopurine, 0.0001-0.0002% of manganese sulfate, 0.005-0.01% of boric acid, 0.5-3% of alpha-fatty acid methyl ester sulfonate, 0.05-0.15% of xanthan gum, 0.1-0.8% of fulvic acid, 3.0-5.5% of ethylene glycol, 3-5% of absolute ethanol and the balance of water. The preparation method comprises the following steps: respectively dissolving brassinolide and 6-benzylaminopurine in absolute ethanol, and mixing to obtain a mother solution; diluting the mother solution, adding boric acid and alpha-fatty acid methyl ester sulfonate, and stirring at high speed; adding xanthan gum, and stirring; and finally, adding manganese sulfate, fulvic acid, ethylene glycol and the balance of water, and stirring uniformly. When being used for coating or application in the breeding season, the preparation can obviously enhance the photosynthetic efficiency of wheat, and promote yield increase.

Description

1. Technical field [0001] The invention belongs to the field of plant growth regulators, and in particular relates to a preparation for promoting the growth and development of wheat in a weak light environment and a preparation method thereof. 2. Background technology [0002] Wheat is the most important food crop and has a major impact on food security and poverty eradication in China and the world. Continuously increasing wheat yield per unit area and increasing wheat production is the goal of unremitting pursuit of agricultural science and technology workers. In recent years, scientists have hoped to increase the yield of wheat through various methods, including traditional genetic breeding, molecular breeding methods, optimized cultivation measures, and the application of growth regulators from external sources. The global wheat yield has increased significantly. As far as China is concerned, due to the accelerated process of industrialization and urbanization, the cont...

Problems solved by technology

But the most prominent effect of gibberellin is to accelerate the elongation of cells, the use of small doses will not work, and large doses may cause leggy and lodging

Although gibberellin also has a certain effect of promoting cell division, it also has a physiological effect of inhibiting maturation. It is difficult to achieve the desired effect in terms of improving wheat yield when used under the low light stress of fruit-wheat intercropping
