High-yield planting method of coix lacryma-jobi as forage

Abstract

The invention relates to a high-yield planting method of coix lacryma-jobi as forage. The high-yield planting method of the coix lacryma-jobi as the forage comprises the following steps: (1) selecting land, weeding, applying base fertilizer, turning over, and carrying out soil preparation; (2) selecting seeds, drying the seeds in the sun, and intermittently soaking the seeds or carrying out seed dressing; (3) sowing, after seedlings emerge, weeding, thinning, thinning again, weeding, weeding again, and carrying out topdressing; (4) carrying out water and fertilizer management and pest control; and (5) cutting green plants, carrying out topdressing, irrigating, and covering stumps with straws after the last green plant cutting is finished, so that heat preservation is carried out, and early germination the next year is promoted. The high-yield planting method of the coix lacryma-jobi as the forage can be used for solving the technical problems that seasonal supply and demand of over-year living forage is unbalanced, summer forage is not resistant to waterlogging and slowly grows at high temperature and environmental requirement is high; biological yield of the coix lacryma-jobi is improved, yield per mu of fresh grasses reaches about 27 tons, on a land mass with fertility of the same class, the yield is increased by more than or equal to 130% compared with the summer forage zea mexicana, annual fresh grass production time is prolonged for more than or equal to 30 days compared with the zea mexicana, and the forage can be harvested for multiple years after sowing once; and the planted coix lacryma-jobi forage is high in yield and wide in application range.

Description

technical field

[0001] The invention relates to a high-yield cultivation method of coix coix, in particular to a high-yield cultivation method of coix coix as pasture. Background technique

[0002] With the development of my country's animal husbandry industry and the need for environmental friendliness, the existing forage crop varieties can no longer meet the needs of my country's current animal husbandry industry. At present, the forage grass that is mainly promoted in production, such as ryegrass, Mexican corn, etc., has low grass yield, is not resistant to high temperature, is not resistant to water stains, has poor disease resistance, and has relatively high environmental requirements. Ryegrass has poor cold resistance and heat resistance, and is a cold-season pasture. Generally, it is only used as perennial pasture in China, and there is a seasonal imbalance in supply and demand. In summer, pastures are not resistant to frost and waterlogging, and grow slowly at high...
