Problems solved by technology

However, these chemical control substances are not easy to enter the inside of the cell, and surfactants such as Tween-20 are generally added to the solution, which has certain damage to the plant cell membrane system
Some trace elements, such as Cu, Zn, Mn, etc. are also chemical control application substances, but these are generally heavy metal elements, and poor concentration control often has the opposite effect

Embodiment 1

[0019] A chemical preparation and chemical control method for improving the grain filling rate and grain yield of wheat, the specific operations are as follows:

[0020] (1) Wheat planting

[0021] Sowed on October 8, 2015, with a seeding rate of 10kg / 667m 2 . Before planting, spread compound fertilizer on the ground, 667m 2 Shi pure N 7.5kg, K 2 O 9kg, P 2 o 5 9kg, plowing, harrowing, sowing, pressing. In the following year, topdressing urea was applied during the rising period of wheat, 667m 2 Apply 7.5kg of pure N. The rest are the same as conventional management.

[0022] (2) Mother liquor preparation

[0023] Potassium phosphate buffer: weigh K 2 HPO 4 129g, KH 2 PO 4 170g was successively put into about 900ml sterile distilled water, stirred and dissolved, and finally adjusted to 1000ml, pH6.6.

[0024] Weigh GABA 10g, vitamin B 6 3 g, stirred and dissolved in 1000 ml of the above potassium phosphate buffer solution (pH6.6).

[0025] (3) Preparation d...

Embodiment 2

[0037] A chemical preparation and chemical control method for improving the grain filling rate and grain yield of wheat, the specific operations are as follows:

[0038] (1) Wheat planting

[0039] Sowed on October 10, 2016, the seeding rate was 12kg / 667m 2 . Before planting, spread compound fertilizer on the ground, 667m 2 Shi pure N 7kg, K 2 O 10kg, P 2 o 5 9kg, plowing, harrowing, sowing, pressing. In the following year, irrigation and urea topdressing at the initial jointing stage of wheat, 667m 2 Apply pure N 8kg. The rest are the same as conventional management.

[0040] (2) Mother liquor preparation

Abstract

The invention discloses a chemical treatment preparation for improving the yield of wheat and a chemical treatment method. The chemical treatment preparation comprises gamma-aminobutyric acid, vitaminB6 and a potassium phosphate buffer solution with the pH of 6.5-6.7, wherein 5-10 g of gamma-aminobutyric acid and 2-5 g of vitamin B6 are added into each L of the potassium phosphate buffer solution. The chemical treatment preparation is wholly and uniformly sprayed onto wheat canopy 5-9 days after flowering of wheat every 2-3 days for two times. Gamma-aminobutyric acid is utilized to improve the leaf chlorophyll content and the photosynthetic efficiency, so that the thousand seed weight principle of wheat grains is improved; vitamin B6 is utilized to achieve physiological actions of regulating C and N metabolism, maintaining the stability of a membrane system under adversity and removing active oxygen; and potassium phosphate is utilized to achieve the functions of regulating the pH value and serving as a nutritional element. The chemical treatment preparation is simple to prepare and feasible and reliable in method, and therefore, is an environment-friendly chemical treatment preparation.

Description

technical field [0001] The invention belongs to the technical field of regulating the physiological process of cereal crops in the later stage of growth, and in particular relates to a chemical control method for improving the grain filling rate and grain yield of wheat. Background technique [0002] Wheat is the most important food crop in the world. In my country, the status of wheat is second only to rice. Wheat production has continued to increase over the past 50 years. Wheat grain yield is affected by the accumulation of carbohydrates and nitrogenous compounds in the vegetative organs before anthesis, the assimilation products after anthesis, the uptake of nutrients by the root system during the filling period, but more importantly by the nutrient content in the vegetative organs during the filling period. Effects on the efficiency of material transport to the grain. 50–95% of N-containing compounds in grains come from storage in the vegetative organs of wheat befor...
