Method for blending and interplanting plants in organic orchard

Abstract

The invention discloses a method for blending and interplanting plants in an organic orchard and belongs to the field of soil nutrient improvement. The method comprises the steps of taking maidenhair, mint and ageratum conyzoides as three aromatic plants in the organic orchard; sowing seeds of the three aromatic plants among fruit trees in March, blending and interplanting the three aromatic plants in a staggered planting mode, and mulching a white film after planting; after the three aromatic plant seedlings grow to be 8-12cm high, performing thinning and transplanting, and maintaining plant line spacing as 0.2*0.4m; watering every 10 days at the growth primary stage of the three aromatic plants, and intertilling and weeding to ensure that no weeds exist in the blending interplanting planting area, wherein the three aromatic plants grow naturally at the medium and later stages and are cut in the last stage of July and October, and stubbles remain among the fruit trees for natural degradation. By blending and interplanting the maidenhair, mint and ageratum conyzoides, the total N, total P and total K contents in 0-20cm and 20-40cm soil layers of the orchard are effectively improved, the soil nutrition of the orchard is improved and the demands of the organic orchard are met.

Description

technical field [0001] The invention relates to the treatment field of orchard soil improvement, in particular to a method for mixing intercropping plants in an organic orchard. Background technique [0002] In addition to being affected by microbial activities, various biochemical reactions in soil also require the participation of various corresponding enzymes to complete. The research results show that soil enzyme activity is closely related to soil nutrients. It not only participates in the natural material cycle including soil biogeochemical processes, but also serves as an active pool of plant nutrient elements. It is often used to characterize the activity of soil microorganisms, soil fertility and indicator of soil quality. Many studies have shown that grass has a certain activation effect on soil enzymes, and the activation effect on soil surface enzymes is obviously higher than that in deep soil, but the effects on different enzyme activities are different.
