A method for improving the soil of double-cropping orchard by intercropping with limited coverage and positioning

Abstract

The invention relates to a method of improvement of garden soil of continuous cropping by limited coverage and positioning intercropping, by the method, seeds profitable for intercropping are sowed in the garden idle soil after the planting of apple seedlings in the direction of planting line of apple seedlings; after the seeds profitable for intercropping are sowed, weeds from the garden are cleaned up completely, and black sun-shade nets are tile-covered on the soil surface planted with seeds profitable for intercropping; after the garden soil is covered with sun-shade nets, the up-holding of the moisture content in the soil is facilitated, the survival, emergence and growth of the seedling and intercropping are conduced; by the method of improvement of garden soil of continuous cropping by limited coverage and positioning intercropping, the coverage of garden soil is taken into account, intercropping of the same period is guaranteed, the technology of farm field irrigation and management is conduced, by the method of limited coverage and positioning intercropping, various contradictions are balanced, and the operation is simple, the method is easy to generalize, the requirements of soil moisture of the soil remediation of the continuous cropping and the survival of the newly planted sapling are soundly fulfilled, profitable intercropping crops are fully utilized for the improvement of continuous cropping soil.

Description

technical field [0001] The invention relates to a method for improving the soil of a heavy-cropping orchard by intercropping with limited coverage and positioning. According to the characteristics of climate and soil improvement, the improved soil and reasonable intercropping are organically combined to provide a new method for improving the soil of a heavy-cropping orchard, which belongs to fruit tree cultivation technology field. Background technique [0002] In recent years, the fruit tree industry has developed rapidly, the replacement has been accelerated, and the old orchards have been continuously cleared and renewed. However, fruit trees in almost every area are facing the threat of heavy cropping disease, which has caused great economic losses to fruit farmers. Fruit tree replanting disease, also known as replanting disease and continuous cropping obstacle, refers to the phenomenon that the same type of fruit tree is repeatedly planted on the same land, and the grow...

Problems solved by technology

However, the spring drought is severe in my country's fruit tree producing areas, and the wind speed is relatively high. Fruit trees are basically planted in spring. In order to improve the survival rate, it is necessary to use plastic film and ground cloth to cover the ground.

If there is no mulch and intercropping is barely possible, the soil will lose water seriously, and the survival rate of both seedlings and intercropping crops will be low

At the same time, due to the disordered growth of intercropping crops, criss-crossing, blocking water flow, and seriously hindering watering and irrigation
