A kind of cultivation method of intercropping alfalfa and wheat under apricot and plum forest in oasis-desert transition zone

Abstract

The invention relates to a cultivation method for intercropping alfalfa and wheat under an apricot and plum forest in an oasis-desert transition zone. Cultivation methods include: soil preparation, apricot and plum gardening, alfalfa and wheat sowing field water and fertilizer management, alfalfa and wheat harvesting, alfalfa pest control. The cultivation method can prevent wind and fix sand, improve soil nutrition, and increase soil water retention capacity, thereby improving the planting environment, increasing the emergence rate of direct-seeded peaches, and the grafting survival rate of apricots and plums in the later stage, and can shorten the period of fruit-bearing of apricots and plums to see benefits by 2 In addition, it can also improve the utilization rate of cultivated land. While harvesting apricots and plums in one year, you can also harvest three seasons of alfalfa, and the yield is about 15% higher than that of growing alfalfa alone. Provide a large amount of forage for cattle and sheep in the area to reduce the ecological pressure on the grassland. The economic benefit and ecological benefit are remarkable, and it has broad application prospects.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a cultivation method for intercropping alfalfa and wheat under an apricot and plum grove in an oasis-desert transition zone. Background technique [0002] The ecological environment in the oasis-desert transition zone is relatively harsh, with strong wind and sand, mostly sandy soil, poor water retention, low organic matter content, and high soil salt content. It needs to drip water again in 1 to 2 days, resulting in extremely low emergence rate and graft survival rate. [0003] Therefore, in the face of this situation, further research and improvement are needed. Contents of the invention [0004] In order to solve the problems in the prior art, the invention provides a cultivation method for intercropping alfalfa and wheat under apricot and plum forests in an oasis-desert transition zone. The cultivation method can improve the utilization rate of arable land. While apric...

Problems solved by technology

[0005] The idea of ​​the present invention is: alfalfa has strong adaptability, has the characteristics of cold resistance, drought resistance, salt and alkali resistance, and deep root penetration into the soil, which plays a very important role in improving soil, preventing wind and sand, and improving the ecological environment; Uneven sowing by machine can easily lead to lack of large seedlings, and in the oasis-desert transition zone with poor soil water retention capacity, water absorption is less after watering, and it is easy to cause no germination due to insufficient water, or lack of water after germination leads to death of young shoots
