A method for high-yield and high-quality farmland mycorrhized crops

Abstract

The invention discloses a method for high-yield and high-quality farmland mycorrhizal crops. Firstly, 10-15 parts of culture substrate hot water and 85-90 parts of river sand are prepared; The liquid arbuscular mycorrhizal fungal agent of the spores is placed in the culture medium for cultivation, and the nutrient solution is sprayed once a week; the seeds are transplanted into the farmland after two weeks of seedling cultivation, and the Hoagland nutrient solution 45 is applied every other week ‑55ml of nutrient supplement, applied four times in total; after the crops grow in the farmland for four weeks, the comprehensive inorganic and organic fertilizers will be fertilized, once a week, and applied four times before and after, and the finished product will be obtained after the crops grow for 55‑60 days. The invention improves the rhizosphere infection rate, yield and grain quality by preparing specific culture substrates, nutrient solutions and inorganic-organic compound fertilizers; meanwhile, compared with the prior art, it also reduces the application of nitrogen and phosphorus fertilizers and reduces production costs.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for high-yield and high-quality farmland mycorrhized crops. Background technique [0002] Arbuscular mycorrhizal (AM) fungi are a type of endomycorrhizal fungi that can form a symbiotic relationship with plant roots. Silk (Intramdical Mycelium, IRM) and root mycelium (Extramdical Mycelium, ERM), the root hyphae can absorb the carbohydrates synthesized by plant photosynthesis transported to the root, and synthesize them into lipids, and then transport them to the outside of the root Mycelium is for the growth and reproduction of AM fungi. The mycelium produced by AM fungi can expand the absorption area of ​​the root system, thereby promoting the absorption of water and mineral element nutrients N, P, K, S, etc. by the host plant. Important achievements have been made on the molecular basis and gene regulation of nitrogen and phosphorus uptake in soil by AM fungi. T...

Problems solved by technology

Because AM fungi mycorrhizate corn under different soil conditions, the yield and quality of some corn are even lower than that of ordinary corn
