Problems solved by technology

[0004] 1. The soil in the sandstorm area is relatively sandy, and the water retention, fertilizer retention, and heat preservation performance are poor. In spring, the land is severely eroded by wind, and it is difficult to guarantee the emergence rate and overwintering rate.
[0005] 2. There is no scientific basis for irrigation, and freshwater resources in northern my country are in short supply. How to maximize the efficiency of water resource utilization is the main challenge for local alfalfa production
[0006] 3. There is no scientific basis for fertilization, serious nutrient loss and waste, and increased economic costs
[0007] 4. The quality of alfalfa is affected due to the uncertain harvest time, which in turn affects the safe overwintering and greening of alfalfa in the second year

Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and taking the Yulin area as an example, which is an explanation of the present invention rather than a limitation.

[0051] A planting method for improving the yield and quality of alfalfa in a sandstorm area, comprising the following steps:

[0052] Step 1, select the planting variety of alfalfa.

[0053] Specifically, alfalfa varieties with strong stress resistance in northern China, foreign alfalfa varieties with a cold resistance index of 1 to 1.5 or fall dormancy grades of 1 to 3 are selected.

[0054]Preferably, Zhongmi No. 3, Gannong No. 3 or WL323.

[0055] Step 2, leveling the land in the planting area.

[0056] Specifically, remove rocks, tree stumps, and unreserved trees and shrubs on the surface of the soil at a depth of about 50cm, cut hillocks and fill depressions, eliminate unevenness, and make the deviation of the flatness of the land not exce...

Abstract

The invention discloses a planting method for improving the yield and quality of alfalfa in windy and sandy areas. Through the protective interplanting of wheat or oats and alfalfa, it can prevent the shallowly sown alfalfa seeds from being blown away by sandstorms in spring, which is conducive to early sowing of alfalfa to take root and preserve moisture, and promote The growth of alfalfa seedlings is beneficial to the growth of alfalfa seedlings; secondly, according to the law of water demand of alfalfa in windy and sandy areas, a scientific irrigation technology model has been established to solve the problems of ineffective evaporation and ineffective irrigation, and achieve water saving of more than 30%; in addition, through the determination of soil elements, The establishment of alfalfa soil nutrient abundance and deficiency index fertilization system in the sandstorm area has solved the problems of excessive fertilization and serious nutrient loss, realized fertilizer saving of more than 30%, increased production by 10% to 20%, achieved cost savings, increased income, and improved fertilizer utilization. The effect of reducing environmental pollution; finally, the harvesting period of the alfalfa is determined in this method, the quality of the alfalfa is improved, and the protein content is maximized.

Description

technical field [0001] The invention relates to the technical field of plant planting methods, in particular to a planting method for improving the yield and quality of alfalfa in sandstorm areas. Background technique [0002] Alfalfa is an important high-quality forage grass for herbivores such as dairy cows. It is known as the "king of grass". Its root system is strong, and rhizobia can fix free nitrogen in the air. use. In recent years, the national policy has vigorously supported the development of the grass industry, which is an important way to promote the economic development of the agro-pastoral ecotone. The development of my country's alfalfa industry is showing an upward trend year by year. Yulin in northern Shaanxi is a strategic layout area for the national grass industry. It is a sandy area in Yulin in northern Shaanxi on the southern edge of the Mu Us Sandy Land in the semi-arid agricultural and animal husbandry transition zone along the Great Wall in northern...
