Abstract

The invention discloses a cultivation method for improving lodging resistance of oats through mechanical seeding. The cultivation method comprises the following steps that early ploughing and deep ploughing are carried out, specifically, early ploughing and deep ploughing are carried out on soil before planting, and the depth is controlled to be 25-30cm; farmyard manure, urea, calcium superphosphate and potassium sulfate are applied; seeding is carried out, specifically, oat seeds are seeded in a mechanical hole seeding mode, the seeding quantity of the oat seeds is that 6-12 oat seeds are seeded in each hole, the hole spacing is controlled to be 10-14 cm, the line spacing is controlled to be 18-22 cm, the functions of raking, leveling and pressing are achieved after mechanical hole seeding, and the emergence rate is guaranteed; and the oats are cultivated according to conventional pest management until the oats are mature. According to the cultivation method for improving the lodging resistance of the oats through mechanical seeding, the yield of the oats in the arid (slope) land can be increased, the lodging resistance can be enhanced, the concentrated rainfall or strong wind resistance of the oats can be prevented by using the planting method, and the yield and quality of the oats can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a cultivation method for improving oat lodging resistance by mechanical sowing. Background technique [0002] Oat (Avena sativa L.) is an annual crop of the Gramineae genus Avena L., which is both grain and feed. It has excellent characteristics such as strong stress resistance, wide adaptability and high nutritional value. Large-scale planting in the region is one of the indispensable forage crops for winter and spring supplementary feeding of livestock and the development of grass husbandry in the interlaced zone of agriculture and animal husbandry in Northwest my country. major. The central part of Gansu Province is a typical dry oat planting area in the country. Due to the tall and scattered field plants in the later stage of oat growth, the degree of community canopy becomes higher, and the support of stems is weakened, which reduces the carbon assimilation of the canop...
