Abstract

The invention discloses a cultivation method for mechanically sowing and improving lodging resistance of tartary buckwheat. The method comprises the following steps: (1) loosening the soil, adjusting the pH value of the soil to 5.0-6.0, and the contents of various nutrients in the soil; 2 Apply the base fertilizer at a certain amount of fertilizer, and then use a seeder to use 16-50kg / hm 2 Tartary buckwheat seeds are sown at a seeding rate of 2 to 4 cm, and the row spacing is 0.2 to 0.5 m; (3) Cultivate according to conventional pest management until tartary buckwheat matures. The invention can not only improve the cultivation efficiency of crops in hilly areas, but also improve the lodging resistance of crops while ensuring the output of crops.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a cultivation method for mechanically sowing seeds and improving lodging resistance of tartary buckwheat. Background technique [0002] Tartary buckwheat belongs to the Polygonaceae (Polygonaceae) buckwheat (Fagopyrum) plant, which has a long history of cultivation in my country and is one of the oldest cultivated crops in the world. Tartary buckwheat has a short growth period and can adapt to cold climate and poor soil; it is mainly distributed in Yunnan, Guizhou, Sichuan, Chongqing, Tibet and other alpine and hilly mountainous areas in southwest China, and it is also planted on a certain scale in Gansu, Shaanxi, and Shanxi. Tartary buckwheat is rich in nutrition and has medicinal value. It has adjuvant therapeutic effect on patients with diabetes, hypertension, and hyperlipidemia. It is a valuable food and medicine crop. In recent years, tartary buckwheat ...
