Problems solved by technology

[0003] The nutrient demand of macadamia nuts is very high. In order to increase the yield of macadamia nuts and reduce diseases, it is usually necessary to use a large amount of pesticides and chemical fertilizers. While promoting the increase in production of high macadamia nuts, part of the fertilizers are lost, which pollutes the environment; not only leads to a large number of The waste of nitrogen and phosphorus resources also causes problems such as high nutrition of water bodies and soil compaction.
Problems such as soil compaction will lead to a single soil microbiota, and a single microbiota will lead to a decrease in soil fertility, which will lead to a reduction in macadamia nut production; how to increase the total amount of soil microorganisms in the root system of macadamia nuts has become an urgent problem to be solved

Abstract

The invention discloses a method for improving macadimia nut root system soil microorganisms. The method comprises the following steps of (1) interplanting of soybeans; (2) multiple cropping of oilseed rape; and (3) strengthening of field management. The soybeans are interplanted in April to May every year, the oilseed rape is subjected to multiple cropping in September to October every year, and a microbial proliferation agent is sprayed properly, so that the soil microbial diversity can be remarkably improved, and the soil quality is improved; in the flower bud differentiation period of the soybeans, plant ash is added for topdressing, and in the budding and bolting period of the oilseed rape, decomposed chicken manure is added for topdressing, so that the soil microbial diversity can be remarkably improved, and the soil quality is improved; and the microorganism proliferation agent contains glucose, bacillus cereus, bacillus subtilis and water-soluble starch, so that the diversity of the soil microorganisms is further improved, and the soil quality is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for improving soil microorganisms in macadamia nut roots. Background technique [0002] Macadamia nut alias: Queensland chestnut, macadamia walnut, macadamia nut, Queensland fruit, is a tree nut native to Australia. Macadamia nuts are evergreen trees and dicotyledonous plants. The crown is tall, with 3 to 4 leaves in whorls, lanceolate, leathery, smooth, with spiny serrations on the edges. Racemes axillary, beige flowers, spherical fruit, leathery, hard endocarp, beige to light brown kernels. It is suitable for growing in mild, humid and windy areas. Among the many dried fruits in the world, macadamia nuts have the highest economic value and have always enjoyed the reputation of "the king of dried fruits". The kernel of macadamia nuts is rich in nutrition (milky white), the exocarp is turquoise, the endocarp is hard and brown, the weight of a single fru...
