How to grow alfalfa

Abstract

The invention discloses an alfalfa cultivation method which includes the steps: turning soil for the first time in late autumn and turning the soil for the second time in early spring; selecting proper autumn dormancy level seeds by the aid of repeated tests; applying biological organic fertilizers; seeding; draining water; returning the soil. The longitude of a local area is a 120.86-degree east longitude, the latitude of the local area is a 32.01-degree north latitude, the climate of the local area belongs to monsoon climates of subtropical zones and warm temperate zones and is gentle, the local area has four distinctive seasons, annual sun exposure is available for 2100-2200 hours, annual total radiation is 110-117 kilocalories per square centimeters, the annual average temperature is 14.6-15.1 DEG C, rainfall precipitation is 1000-1060 millimeters, the PH (potential of hydrogen) value of the soil is 6.5-6.8, about 3kg of seeds are sowed per mu for 5cm depth, and each line spacing is 10-20cm. The alfalfa cultivation method has the advantages of high yield per mu, fine grass quality, safety and no pollution.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating alfalfa. Background technique [0002] Medicago sativa, formerly known as: Medicago sativa, also known as: alfalfa, Rosacea, leguminous, alfalfa is a perennial herb, with strong roots, deep into the soil, and well-developed root necks. The stems are erect, clustered or even recumbent, quadrangular, glabrous or slightly pilose, with lush branches and leaves. It is cultivated all over the country or in a semi-wild state. It grows in fields, roadsides, wilderness, grasslands, river banks, and valleys. Alfalfa seeds are small, young shoots are thin and weak, and the top soil strength is poor. Soil preparation must be fine and the ground is flat. , the soil clods are finely broken, no weeds, and the moisture content is good; alfalfa has a well-developed root system and penetrates deep into the soil, and the sowing land must be plowed deeply to make the ...

AI Technical Summary

Problems solved by technology

The traditional planting areas of alfalfa are in the Northwest and Northeast. The disadvantages are that the land conditions are relatively poor, the management is relatively loose, and the extreme low temperature weather lasts for a long time, which is not conducive to the growth of alfalfa, so the annual output is low. In addition, the traditional planting areas are mostly arid areas. , less precipitation, not conducive to high yield
