The invention discloses a calcareous purple soil modifier and a preparation method thereof, and belongs to the technical field of soil modifiers, the calcareous purple soil modifier comprises the following components by weight: 15-35 parts of rape straw, 10-30 parts of pleurotus eryngii straw, 10-30 parts of hypsizygus marmoreus residue, 10-25 parts of humic acid, 12-15 parts of activated clay mineral, 5-10 parts of cow dung, 2-4 parts of plant ash, 2-4 parts of tobacco powder, and 1-2 parts of flue ash. 2-3 parts of amino acid powder, 1-2 parts of borax, 1-2 parts of ammonium molybdate, 1-2 parts of zinc sulfate, 1-2 parts of amino acid chelated iron and 2-3 parts of a compound microbial agent. Compared with existing substances, the modifier can delay the degradation rate of organic matters and improve the supplement effect of the organic matters in the soil, the problem of heavy metal enrichment is avoided, and the problems existing in existing modifiers are effectively solved.

The present invention provides a self-generated nitrogen-fixing strain and its application, belonging to the field of microbial technology. The self-generated nitrogen-fixing strain of the present invention is BWLY3X‑6, which belongs to Klebsiellavariicola, and the deposit number is GDMCCNO: 63038. The present invention also provides a self-generated nitrogen-fixing bacterial agent, including a bacterial suspension of the strain BWLY3X‑6. The strain BWLY3X‑6 and its bacterial suspension of the present invention can effectively increase the root length, plant height, fresh weight and total nitrogen content of banana plants, and have a good growth-promoting effect on bananas.

This invention discloses a method for intercropping multiple forage grasses in citrus orchards. Addressing the drawbacks of traditional clean cultivation management and single-grass intercropping in citrus orchards, it employs a mixed sowing of four varieties: ryegrass, white clover, gnaphalium affine, and milkvetch. It includes standardized steps for orchard pretreatment, seed pretreatment, precision sowing, seedling management, growth period management, forage harvesting and returning to the field, and water and fertilizer regulation. Strict control of parameters at each stage is maintained, and a specific ratio of compound bio-fertilizer is selected to optimize the citrus water and fertilizer management scheme. This invention achieves year-round closed coverage of the citrus orchard through the complementary characteristics of the four forage grasses, improving the control rate of noxious weeds, reducing soil erosion, increasing soil organic matter content, and increasing citrus yield per acre. It combines the advantages of improving soil fertility, suppressing weeds and conserving moisture, improving quality and efficiency, and promoting a green and ecological environment, thus constructing a highly efficient and sustainable citrus ecological planting system.
