High-yield cultivation method for Chinese wildrye

Abstract

The invention discloses a high-yield cultivation method for Chinese wildrye. The method comprises the first step of seed cleaning; the second step of land selection and soil preparation; the third step of timely planting; the fourth step of the proper seeding rate; the fifth step of the planting mode; the sixth step of soil moisture content guaranteeing, wherein the technical measures of moisture improving through irrigation before planting or moisture preservation through irrigation after planting are adopted, and it is guaranteed that the seedlings of the Chinese wildrye emerge and the Chinese wildrye grows; the seventh step of scientific fertilization; the eighth step of field management; the ninth step of defoliation modulation; the tenth step of timely harvesting. The method is tested and studied in Litong District, Wuzhong City, Ningxia Hui Autonomous Region, the high yield level that 500 kilograms of Chinese wildrye hay are produced averagely per mu and the highest yield per mu is 550 kilograms is obtained through cultivation, a high-yield cultivation and management matching technology is solved, the technicality is reliable, and as is proved by practice, the method can be popularized and applied to the field of agricultural technology in a large area mode.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a high-yield cultivation method of Leymus chinensis. Background technique [0002] Leymus chinensis is a perennial gramineous forage grass with many leaves, rich nutrition and good palatability. All kinds of livestock like to eat it all year round. It is an excellent forage grass. Leymus chinensis is distributed in the Songnen Plain in Northeast my country and eastern Inner Mongolia. It is planted in the provinces (autonomous regions) of Northeast China and North China. The area of ​​Leymus chinensis planted in northern my country is very limited. Leymus chinensis is sown in spring in northern my country, and its growth period is about 150 days. It is a good pasture grass. But at present, due to many reasons such as soil, water resources, climate, heat conditions and planting techniques in Northwest China, the output of Leymus chinensis is unstable and not high. In order to d...
