Abstract

The invention discloses a fertilizing method capable of improving the lodging resistance of alfalfa plants. The fertilizing method comprises the following steps: step one, mixing a first soil layer with the depth of above 15 cm with a first organic fertilizer and vermiculite to obtain first soil before sowing; step two, mixing a second soil layer with the depth of 15 to 30 cm with mixed powder anda second organic fertilizer to obtain second soil; step three, after mixing and stirring a third soil layer with the depth of below 30 cm with a third organic fertilizer uniformly, paving the mixturein a room of 25 to 28 DEG C for 12 to 18 h so as to obtain third soil; and step four, paving liquid storage layers between the third soil and the second soil and between the second soil and the firstsoil respectively so as to obtain an alfalfa planting land. Fertilization is carried out on the soil of the planting land in batches, the fertilizer with the ingredients in proportion is applied at different periods so as to improve the lodging resistance of alfalfa, so that the purpose of improving the alfalfa yield and product quality is reached.

Description

technical field [0001] The invention relates to the field of alfalfa planting. More specifically, the present invention relates to a method for improving lodging resistance of alfalfa by applying different fertilizers to soil layers of different depths and at different stages of alfalfa growth. Background technique [0002] Alfalfa is known as the "King of Forage Grass". It not only has high yield, but also has excellent grass quality, and all kinds of livestock and poultry like to eat it. The current planting area of ​​alfalfa in my country is about 1.33 million hm 2 . With the development of the commodity economy, the scale of alfalfa industrialization has developed rapidly in recent years, and the planting area of ​​alfalfa is expanding. However, in the main producing areas of alfalfa, there is a common problem of uncoordinated vegetative growth and reproductive growth, that is, in humid climates 1. Under good fertility conditions, alfalfa is prone to leggy growth, exc...
