Sandy land intercropping method for intercropping forests, grains, grass and vegetables under walnut forests

Abstract

The invention relates to a sandy land intercropping method for intercropping forests, grains, grass and vegetables under walnut forests. According to the method, quinoa is planted in spaces among trees of semi-closed walnut forests, by a good windproof effect of the walnut forests and a humidifying and cooling effect on a small environment and in combination with seeding in a proper period, the emergence and seedling protection rate of the quinoa is greatly improved, diseases, pests and lodging of the quinoa are reduced, the yield and quality of the quinoa are improved, and high economic output under the forests is created; astragalus sinicus is planted in the small environment for shading, cooling and humidifying under the walnut forests, so that the benefit of planting under the forestsis further improved, and a fertile land effect is achieved; and turnip (Brassica campestris) is planted after the harvest of the quinoa to make full use of the light and heat resources after the harvest of quinoa and further improve the economic output of plots.

Description

technical field [0001] The invention relates to an intercropping method suitable for walnut forest, grain, grass and vegetables in sandy land in Hetian area. Background technique [0002] By the end of 2018, the walnut planting area in Hotan, Xinjiang had reached 1,719,400 mu. However, in the five to seven years before the fruit harvest period, the walnut trees are small and have no economic benefits. The development of understory planting is of great significance. Traditional walnut forest planting includes planting wheat, corn, cotton, vegetables, etc. under the forest, and the benefits are relatively low. High-efficiency walnut forest planting projects are urgently needed in production. Quinoa is rich in vitamins, polyphenols, flavonoids, saponins and phytosterols, which have a variety of health effects and are rich in nutrition. It is highly praised by the healthy diet industry. The current market price is generally high, and it has great development potential. As an ex...

Problems solved by technology

Unfavorable conditions for planting quinoa in the Hotan area: Quinoa originally grew in the Andes, likes a cool and cool climate, and is resistant to drought and saline alkali. However, the altitude in the Hotan area is low, the temperature and ground temperature rise rapidly in spring, and the surface of the sandy soil is prone to dehydration. The depth of sowing is shallow, and high temperature will easily cause quinoa seeds to dry out and emerge difficult; high temperature in spring will cause serious pests and diseases at the seedling stage; high temperature and water and fertilizer management in summer will easily cause quinoa to grow excessively, and strong winds in summer will easily cause lodging

Patent application 201811016839.9 describes a method of planting quinoa in the shade of almond trees, but the shading degree of walnut trees is high, and quinoa cannot survive in the shade. Instead, quinoa is planted in the well-lit places between the rows of young walnut trees It works
