Construction method of apple tree II ryegrass compound system in sandy land in arid region

Abstract

The invention provides a construction method of an apple tree II ryegrass compound system in an arid region, and belongs to the technical field of agricultural planting. The apple tree II ryegrass compound system is composed of apple trees and ryegrass, and the ryegrass is planted between planting rows of the apple trees. In the apple tree II ryegrass compound system, the ryegrass has the characteristics of reducing soil salinity, increasing soil organic matters, reducing ground temperature and wind speed and increasing yield in one year; and the apple trees have the effects of producing apples and improving the microclimate environment. The apple trees and the ryegrass are combined to form a mutually-promoted benign apple tree II ryegrass composite system, so that considerable economic benefits are created, and meanwhile, the soil quality of the arid region and the ecological protection effect of improving microclimate can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for constructing an apple tree‖ryegrass composite system in sandy land in an arid region. Background technique [0002] Southern Xinjiang has a warm temperate continental arid climate. This region includes the Tarim Basin (including the Taklamakan Desert). Therefore, the Huanta Oasis is dry and rainless all year round, the soil moisture is scarce, and the farmland ecosystem is fragile. Orchards reclaimed on sandy soil have low soil organic matter content and require more fertilizers; the utilization rate of the blank space between the rows of fruit trees is low, and the soil anti-salt is serious due to evaporation between the rows; the dry farmland microclimate of the orchard leads to low fruit quality, so the orchard The overall productivity is not high, which restricts the sustainable development of the fruit industry in Huanta Oasis. [0003...

AI Technical Summary

Problems solved by technology

[0004] If ryegrass is planted between rows of apple trees, it can not only convert the organic matter of ryegrass into soil organic matter, improve the soil fertility of the orchard, and improve the land utilization rate, but also reduce the temperature of the orchard in summer and conserve the soil moisture of the orchard by covering with grass. , inhibit the rise of soil salinity, improve the climate environment of orchard farmland, however, in the prior art, there is no report on the use of apple tree intercropping ryegrass in sandy land in arid areas to improve soil quality, inhibit soil anti-salt, and improve orchard microclimate
