Method for high-yield cultivation of hybrid millet of coastal moderate and severe saline and alkaline land

Abstract

The invention discloses a method for high-yield cultivation of hybrid millet of coastal moderate and severe saline and alkaline land. The method comprises the following steps of: (A), performing saline-alkali-resistant pelleting treatment on millet seeds, namely wrapping a layer of saline-alkali-resistant pelleting agent on the surfaces of the millet seeds to form pelleted seeds with the diameters of 2 to 5mm; (B), performing post-rain shallow seeding, namely performing precision drilling by using seeding machinery when the single rainfall capacity is over 50mm; (C), performing chemical weeding, namely adding 20 to 25kg of water into 100ml of herbicide and 10mg of anti-lodging agent and uniformly spraying on each mu of land at a 3-5 leaf stage of millet; and (D), applying a small amount of fertilizers for multiple times, namely applying 5 to 10kg of diammonium phosphate serving as seed fertilizer to each mu of land, additionally applying 5 to 7.5kg of urea and 7.5 to 10kg of diammonium phosphate to each mu of land at an elongation stage, and additionally applying 15 to 20kg of urea and 5 to 10kg of potassium sulfate to each mu of land at a heading stage. The high-yield cultivationof the hybrid millet in coastal saline and alkaline land is realized by comprehensively applying technologies such as a saline-alkali-resistant pelleting technology, a post-rain shallow seeding technology, a precision drilling technology, a chemical weeding technology and multiple application of a small amount of fertilizers.

Description

technical field [0001] The invention relates to the field of agricultural planting and cultivation, in particular to a high-yield cultivation technology of hybrid millet on coastal medium-severe saline-alkali land. Background technique [0002] Millet (Setaria italica (L.) P.Beauv) is also known as millet, and belongs to the genus Setaria italica of the Poaceae family. Millet originated in my country and is cultivated in Korea, Japan, India, West Africa, Europe and America. In the 1980s and 1990s, due to the utilization of hybrid vigor in maize, its acreage decreased sharply. At the beginning of this century, with the rapid promotion of the "Zhang Zagu" series of hybrid millet at a rate of 3-5 times per year, its area has recovered. [0003] Due to the limitations of factors such as the market, the promotion of hybrid millet cannot occupy the arable land of staple food crops, but can only target marginal land such as drought and salinity. It is traditionally believed that...

Problems solved by technology

[0004] At present, there are few studies on the cultivation of hybrid millet on saline-alkali soil, and the high-yield cultivation technology on medium-severe saline-alkali soil needs to be studied
