Description

Method for intercropping walnut trees, grains, grass and vegetables in sandy soil land

Technical Field

The invention relates to a method for interplanting walnut trees in sandy soil under forest, grains, grass and vegetables, which is suitable for the farmland area.

Background

By the end of 2018, the walnut planting area in the Xinjiang Hetian area reaches 171.94 ten thousand mu, but the walnut trees are small in 5 to 7 years before the full bearing period, no economic benefit exists, and the significance of developing planting under forests is great. Traditional walnut understory planting comprises understory planting of wheat, corn, cotton, vegetables and the like, the benefit is low, and an efficient walnut understory planting project is urgently needed in production. The quinoa is rich in vitamins, polyphenols, flavonoids, saponins and phytosterols, has various health effects, is rich in nutrition, is highly advocated by the healthy diet industry, has generally higher current market price and has great development potential. The milk vetch is used as an excellent green manure and pasture dual-purpose crop, has good palatability and rich nutrition, and can be used as a high-quality feed and a protein supplementing feed. The forage grass in the Hetian area is quite lack, the price is generally higher, and the shade-resistant characteristic of the milk vetch is quite suitable for planting under the forest. The Qamgur is an alkali-rich plant eaten by Uygur people in Xinjiang for more than 2000 years, is also a stock food on a dining table in Xinjiang, and is a necessary food for the local elderly with long life. The pharmaceutical name of the Brassica rapa is turnip, which is a two-year cruciferous herbaceous plant and is rich in various organic nutrient substances such as organic active alkali and the like. The research and development of a 'forest-grain-grass-vegetable' intercropping technical mode taking quinoa introduction and planting as a core provides new technical reserve and support for poverty removal work in the Hetian area.

The problems of intercropping of grains, grass and forests in the traditional forests are mainly reflected in that the yield is low and the quality is poor due to low price and shading of crops, and particularly, the planting benefit under the forests continuously declines along with the increase of the age of walnut trees and the increase of the canopy density. The method is characterized in that the high-value chenopodium quinoa is planted in the vacant land with good illumination conditions among 1-4-year-old young walnut trees to improve the economic output of planting under the whole forest; leguminous forage astragalus sinicus is planted at the shading position under the walnut tree, so that the under-forest planting benefit is further improved, and the effect of soil fertility is achieved; after the chenopodium quinoa is harvested, turnip (Brassica rapa) is planted to fully utilize photo-thermal resources of the harvested chenopodium quinoa and further improve the economic output of the land parcel.

The beneficial conditions for growing the quinoa in the Hetian region are mainly shown in that the Hetian region is close to the Kunlun mountain, the altitude is 1250-1450 m, the frost-free period is as long as 170-201 days, the photo-thermal resources are rich, the accumulated temperature is 4200 ℃ at the temperature of more than or equal to 10 ℃, the temperature difference between day and night is large, and the rainfall is rare. Adverse conditions for growing chenopodium quinoa in the Hetian area: chenopodium quinoa grows in the Andes mountain, likes cold and cool climate, is drought-resistant and saline-alkali-resistant, has low altitude in Hetian area, and has rapid rise of temperature and ground temperature in spring, the surface layer of sandy soil is easy to lose water, and Chenopodium quinoa seeds are sowed deeply and shallowly, and the Chenopodium quinoa seeds are easy to fall dry and grow seedlings at high temperature; the high temperature causes serious plant diseases and insect pests in the seedling stage in spring; high temperature and water and fertilizer management in summer easily cause vain growth, and strong wind in summer easily causes lodging. Patent application 201811016839.9 describes a method for growing quinoa under the shade of apricot forest, but the shade of walnut tree is high, quinoa planted under the shade can not survive, and quinoa planting in the place with good illumination between young walnut forest rows is feasible. The adverse conditions for planting the milk vetch in the Hetian are mainly as follows: in spring and summer, the temperature and the light are strong, the rain is less, the dryness is more than 20, and the milk vetch is shady and can grow well under the shade of the walnut tree.
