Method for raising yield of alfalfa and improving quality of alfalfa

Abstract

The invention discloses a method for raising the yield of alfalfa and / or improving quality of alfalfa. The method for raising the yield of alfalfa and / or improving quality of alfalfa includes the following two steps that 1, soil in which the alfalfa is planted is ploughed, and the ploughing depth is 10-14 cm; 2, fertilizer application is conducted on the soil in which the alfalfa is planted. A fertilizer special for the alfalfa is applied to the alfalfa and is prepared from, by mass, 5000 parts of superphosphate, 4.7-9.4 parts of ammonium molybdate and 0.88-1.50 parts of sodium nitroprusside. It is proved by experiments that by means of the method, the yield of the alfalfa can be remarkably raised, the quality of the alfalfa can be remarkably enhanced, and high economic value is achieved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for increasing the yield of alfalfa and improving the quality of alfalfa. Background technique [0002] Alfalfa is an important perennial leguminous forage widely planted all over the world. It has the characteristics of high yield, excellent quality and long service life, and is known as the "king of forage". In my country, alfalfa planting is mainly distributed in Inner Mongolia, Heilongjiang, Xinjiang, Gansu and other areas, where the climate is dry, the land is barren, the temperature in winter is low, and the frost-free period is short. As a perennial crop, with the increase of planting years, the regeneration ability of alfalfa itself weakens, which affects its absorption and utilization of water and nutrients, resulting in a downward trend in its yield and quality in the late planting period, reducing the productivity of alfalfa artificial grassland. become the limit...

AI Technical Summary

Problems solved by technology

As a perennial crop, with the increase of planting years, the regeneration ability of alfalfa itself weakens, which affects its absorption and utilization of water and nutrients, resulting in a downward trend in its yield and quality in the late planting period, reducing the productivity of alfalfa artificial grassland. become the limiting factor for alfalfa production

At present, reseeding alfalfa is usually used to solve this problem in production, but the cost of reseeding is high, and the sown alfalfa grows slowly in that year, and there is basically no income
