Method for producing silage raw material by intercropping sweet sorghum and feeding peas

Abstract

The invention discloses a method for producing a silage raw material by intercropping sweet sorghum and feeding peas, which belongs to the field of forage grass planting, and mainly comprises the following steps: sowing the sweet sorghum in drill, intercropping the feeding peas between two rows of the sweet sorghum in drill, and sowing the feeding peas in drill; when the height of the sweet sorghum is 1.2-1.5 m, the sweet sorghum and the feeding peas are cut together, the stubble height is 10-15 cm, cutting is repeated every 40 days, and cutting is conducted 3-5 times a year. The mixed sowing of the sweet sorghum and the forage peas can effectively improve the fresh and dry grass yield of the sweet sorghum, improve the nutritional quality of the mixed forage grass, and increase the economic income. High-yield and high-quality forage grass is produced on limited land in Chengdu plain and middle and low altitude mountainous areas, the problem of insufficient supply of the local forage grass is solved, the breeding cost is reduced, and balanced supply of the forage grass is realized under the condition that the forage grass is tired in winter and spring.

Description

technical field [0001] The invention belongs to the field of forage planting, in particular to a method for producing silage raw materials by intercropping sweet sorghum and forage peas. Background technique [0002] In recent years, my country's grass husbandry has developed rapidly, but the land for planting forage grass is limited. Therefore, improving land utilization and developing efficient planting patterns are the effective guarantees for the development of modern animal husbandry. The animal husbandry industry belt in the Chengdu Plain is one of the four dominant animal husbandry industry belts in Sichuan Province, and there is a greater demand for high-quality forage. However, more high-quality forage is produced on limited land for the Chengdu Plain and low-altitude animal husbandry. key to industry development. [0003] Sweet sorghum is an annual forage plant with the characteristics of high yield, drought resistance and hard work. Feed lentils are leguminous ...

AI Technical Summary

Problems solved by technology

The disadvantages of this technology are: (1) The use of film to cover the land causes white pollution

(2) It needs to consume a lot of human resources when setting seedlings and placing seedlings, increasing the production cost of growers

(3) Interplanting of sorghum and labrador causes dislocation in time and space, resulting in that the nutritional quality of the two forage grasses is not optimal when the forage grass is harvested

(4) This method is suitable for dry farming areas in the north, but not for the southern areas

[0006] The shortcoming in " the influence of different planting densities on the yield of silage corn mixed forage lentils " is: (1) corn is an annual plant, there is no new tiller after cutting, and it cannot grow again, so it can only be cut once, thereby Unable to produce more forage on the limited land in the south

cause a waste of time and space

(2) Forage lentils are forage crops with many winding branches. If the planting density of corn cannot be determined, it will cause yield reduction.
