Mixed sowing method and mowing device of ryegrass and white clover in karst area

Abstract

The invention discloses a mixed sowing method of ryegrass and white clover and a mowing device in a karst area. The method comprises the steps of: plowing the land with a thickness of 20-30 cm, removing weeds; applying 30-40 kg of calcium magnesium phosphate fertilizer or 1000kg of farmyard manure; ryegrass and white clover are sown at a ratio of 3:1, the ryegrass strip sowing spacing is 20-30cm, and the white clover is sown among them; water after covering the soil, and weeds are removed in time during the seedling period; mowing: 38-42 days for the first mowing, the stubble height is not less than 2cm, and 5kg / mu of nitrogen fertilizer is added after 2-3 days, and then harvested every 20-30 days. The mixed sowing of ryegrass and white clover in the present invention can make full use of the planting land, and the mixed sowing according to the set ratio can greatly increase the yield. After the mixed sowing, the yield per mu can be increased by more than 300kg. Great improvement, one-time mixed harvesting, reducing the process of feeding cattle and sheep, greatly improving the freshness of tender grass, greatly improving the meat quality and nutrition of cattle and sheep, and the benefits of increasing farmers' income are obvious.

Description

technical field [0001] The invention belongs to the technical field of mixed sowing of ryegrass and white clover in karst areas, and relates to a mixed sowing method and mowing device of ryegrass and white clover in karst areas. Background technique [0002] The southwest karst area is located in the subtropical monsoon climate zone, with good rain and heat conditions. The special "dual" structure of karst geology is not suitable for traditional agricultural planting, but suitable for the development of grassland vegetation. Grass is the fastest and most effective method to increase surface vegetation coverage and reduce soil erosion in the short term. Grass mixed sowing is currently an internationally recognized grassland planting model. It is an effective way to increase vegetation coverage, reduce soil erosion and increase farmers' income in the short term. [0003] At present, the mixed planting methods of ryegrass and white clover in karst rocky desertification areas h...

AI Technical Summary

Problems solved by technology

Karst areas are suitable for growing white clover and ryegrass, which are important forages for feeding cattle and sheep in this area. It is beneficial to maintain the freshness of the tender grass, which is not conducive to the growth of cattle and sheep, and the pasture is harvested at one time. During the growth process, the pasture is blocked by each other, resulting in poor sunlight and ventilation effects, which is not convenient for the rapid growth of the pasture, and it is easy to cause the pasture to grow. The quality deteriorates during the process, which is not conducive to the growth of cattle and sheep, and affects the quality of beef and sheep meat
