Method for improving soil nutrition of organic orchard

Abstract

The invention discloses a method for improving the soil nutrition of an organic orchard, belonging to the field of soil improvement of the orchard. The method comprises the steps: in the organic orchard of which the soil needs to be improved, taking maidenhair and spearmint as two aromatic plants to be planted; in March each year, sowing seeds of the two aromatic plants between the lines of fruit trees, i.e., mixedly intercropping the two aromatic plants in an alternate line planting method, and covering with a white plastic thin film after planting; when the height of seedlings of the two aromatic plants is 8cm to 12cm, carrying out thinning and transplanting, and keeping the spacing in the rows and spacing between rows 0.2*0.4m; in the early growth stage of the aromatic plants, watering every ten days, weeding, maintaining no weeds in the planting area, naturally growing the aromatic plants maidenhair and spearmint in the middle and later periods, mowing the aromatic plants in the last ten-day period of July and October, and naturally decomposing remains after mowing between the lines of the fruit trees. By planting the aromatic plants maidenhair and spearmint in the mixed way, the contents of total nitrogen, total phosphorus and total potassium in the 0-20cm and 20-40cm soil layers in the orchard soil are effectively improved, nutrients of the orchard soil are enriched, and the requirements of the organic orchard are met.

Description

technical field [0001] The invention relates to the field of orchard soil improvement treatment, in particular to a method for improving organic orchard soil nutrition. 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.
