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, and in particular to a high-yield cultivation technology of hybrid millet on moderately severe coastal saline-alkali land. Background technique

[0002] Millet (Setaria italica (L.) P.Beauv), also known as millet, belongs to the genus Setaria of the Gramineae family. Millet originated in my country and is cultivated in Korea, Japan, India, West Africa, Europe and the United States. In the 1980s and 1990s, the planting area of ​​corn decreased sharply due to the utilization of hybrid advantages. At the beginning of this century, with the rapid promotion of the "Zhangzagu" series of hybrid millet at a rate of 3-5 times per year, its area has recovered.

[0003] Due to market and other factors, the promotion of hybrid millet cannot occupy cultivated land for bulk food crops, but can only target marginal lands such as drought and saline-alkali. Traditionally, millet is believed...
