Embodiment Construction

[0011] A weeding method for millet planting, comprising the following steps: Step 1, select millet seeds, soak the millet seeds with brassinolide aqueous solution (hereinafter referred to as BR) with a concentration of 0.001-1 mg / L for 12 hours, and set aside; Step 2, Sow the millet seeds soaked in step 1 according to the conventional sowing method. When the millet seedlings grow to five leaves, spray the herbicide with a concentration of 7.5 mg / L in the millet field. After 24 hours, spray the herbicide on the leaves with a concentration of 0.0125 Brassinolide aqueous solution of ~0.4mg / L; Described herbicide is the iodosulfuron-methyl sodium salt · metrisulfuron-methyl water-dispersible granule and alkylethylsulfonate in a weight ratio of 9:1 of aqueous solution. In actual implementation, the steps of spraying the herbicide and the brassinosteroid aqueous solution in the aforementioned step 2 can be changed.

Abstract

The invention provides a weeding method for millet planting. The weeding method comprises the following steps: selecting millet seeds and soaking the millet seeds with brassinolide with the concentration of 0.001-1mg / L; spraying a weed killer with the concentration of 7.5mg / L in farms after seeding, and spraying the brassinolide with the concentration of 0.0125-0.4mg / L on foliages after 24 hours, wherein the weed killer is a water solution of iodosulfuron-methyl-sodium.mesosulfuron-methyl water dispersible granules and alkyl ethyl sulfonate at a weight ratio of 9 to 1. According to the weeding method, the seeds are soaked with the brassinolide solution, so that the plant height and biomass of the grown millets can be improved, and the photosynthetic pigment content in seeding leaves of the millets can be reduced to a certain extent. According to the weeding method, the seeds and seedlings of the millets are processed with the brassinolide, so that the resistance of the millets to the weed killer is improved; modernized operation in the millet planting is convenient; the application range of the existing weed killer is expanded.

Description

technical field [0001] The invention relates to the technical field of weeding, in particular to a weeding method for millet planting. Background technique [0002] Millet belongs to the family Gramineae and is one of the main cultivated crops in my country. It is drought-resistant, barren-resistant, strong in stress resistance and wide in adaptability. It is a very good drought-resistant crop. Shanxi is the origin and one of the main production areas of millet, with an annual planting area of ​​about 4 million mu, which is the main miscellaneous grain for the people of Shanxi. Millet is millet after shelling. Millet contains 8 kinds of amino acids needed by the human body. The protein content and fat content are higher than rice. It has high nutritional value and plays an irreplaceable role in people's life. Weeding in millet fields is a labor-intensive operation. The vicious competition of weeds in the field will directly affect the yield and quality of millet. However, t...
