Abstract

The invention relates to the technical field of agricultural planting, in particular to a high-yield planting method of alfalfal. The high-yield planting method comprises the steps of soil preparation, seed treatment, sowing, thinning, planting management and harvesting management, wherein the seed treatment comprises the steps of rinsing alfalfal seeds, screening to remove empty seeds, irradiating the alfalfal seeds with rays, conducting freezing, conducting drying, soaking the seeds in a seed agent, spraying a disease-resistant treatment agent on the surfaces, stirring with bacteria, and finally performing coating treatment. According to the method, management, control and improvement are conducted from multiple aspects of planting, planting soil can meet the growth requirement of alfalfa for a long time, the germination potential and the germination rate of the alfalfa seeds can be remarkably increased by treating the seeds, the plant biomass is effectively increased, and the grownalfalfa grows fast, is high in drought resistance, is vigorous in growth force and high in survival rate, and has the practical application value.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield planting method of alfalfa. Background technique [0002] Alfalfa (Medicago sativa) belongs to the Leguminosae genus Medicagospp. It is a perennial herbage, known as the king of herbage because of its good stress resistance, high quality and high yield. Alfalfa can improve the soil through biological nitrogen fixation, which not only has high economic value, but also has great value in the protection and restoration of the ecological environment. It plays an important role and is widely planted in saline-alkali land, tidal flats and soil degraded areas for land improvement and grassland restoration. [0003] In recent years, alfalfa has been developed and planted on a large scale as the main forage, which has led to an increase in the production of alfalfa. But because alfalfa belongs to leguminous crops, its seed hard rate is higher, and when germina...
