Method for planting alfalfa in typical grassland rainfed condition

Abstract

The invention discloses a method for planting alfalfa in the typical grassland rainfed condition. The method comprises selecting grassland NO.2 alfalfa, grassland NO.3 alfalfa or Aohan alfalfa seeds to serve as alfalfa seeds to be sown to be subjected to hull breaking; performing soil preparation and base fertilizer applying on a land block in the typical grassland, and performing mixed sowing on alfalfa seeds and gramineous forage grass seeds in the first or the middle ten days of June, wherein the alfalfa seed sowing rate is 7.88kg / hm<2> to 15 kg / hm<2>, the gramineous forage grass seed sowing rate is 21.43 kg / hm<2> to 24 kg / hm<2>, and the sowing depth is in a range of 1cm to 3cm;compacting the land lock; harrowing the land block before alfalfa seedling emergence after land block caught in the rain; cradling the alfalfa in the last ten days of July from the second year, wherein the cradling stubble height is larger than or equal to 5cm. According to the method, the alfalfa is planted in large area in the typical grassland based on the rainfed condition, and the alfalfa planting cost in the typical grassland is reduced.

Description

technical field [0001] The invention relates to planting technology, in particular to a method for planting alfalfa under rain-fed conditions in a typical grassland area. Background technique [0002] Alfalfa (Medicago sativa L.) is a perennial leguminous herbage from the Near East and Central Asia. It has the characteristics of high grass yield, strong palatability, long lifespan, and rich nutrition. It is known as the "king of grasses". [0003] Alfalfa is the most widely distributed cultivated herbage in the world today. The main production areas in my country are Northwest, North China, Northeast China, and the Jianghuai River Basin. Vigorously promoting the planting of alfalfa can improve the production level of animal husbandry, promote the virtuous cycle of grain, livestock and grass, and is of great significance in promoting agricultural efficiency and increasing agricultural income. Moreover, alfalfa can also effectively prevent soil erosion, has the functions of w...

AI Technical Summary

Problems solved by technology

However, the alfalfa planting method based on irrigation conditions makes the cost of alfalfa plantation (such as the cost of irrigation equipment, the cost of manpower required for irrigation) relatively high, and is not suitable for large-scale promotion in typical grassland areas.
