AMF复合菌剂对寒地水稻光合作用和生长效应的影响

AMF Complex Fungicides: Effects on Photosynthesis and Growth of Rice in Cold Region

研究AMF复合菌剂对水稻生长及产量的促进效果,旨在为绿色高产水稻的种植提供技术基础。本试验以水稻(Oryza sativa L.)为研究对象,测定大田条件下水稻植株的光合作用参数、总生物量和水稻产量及其构成因素。AMF复合菌剂能显著提高内生真菌在水稻根部的侵染率,AMF+PI+AR处理的侵染率高达86.7%,能与水稻根系建立良好的共生关系。施加AMF复合菌剂能提高水稻叶片的光合作用强度和水稻总生物量,与PI、AR、AMF、FP、CK相比水稻的总生物量分别提高了25.9%、31.7%、24.4%、17.2%、38.1%。AMF复合菌剂种植与常规农作物施肥种植相比产量提高了6.9%。AMF复合菌剂能够有效促进水稻生长并提高产量,相比较常规农作物施肥有着零施肥、低成本、高产量的优势,可实现水稻清洁生产并解决稻田面源污染问题。

This study investigated the promoting effect of AMF complex fungicides on the growth and yield of rice, aiming to provide a technological basis for the cultivation of green and high-yielding rice. This experiment was conducted on rice(Oryza sativa L.) to determine photosynthetic parameters, total biomass,yield and yield constituent factors of rice plants under field condition. AMF complex fungicides significantly increased the infestation rate of endophytic fungi in rice roots, and the colonization rate of AMF + PI + AR treatment was as high as 86.7%, which established a good symbiotic relationship with rice roots. The application of the AMF complex fungicides increased the photosynthetic intensity of rice leaves and total rice biomass, and the total rice biomass increased by 25.9%, 31.7%, 24.4%, 17.2% and 38.1% compared with that of PI, AR, AMF, FP and CK, respectively. AMF complex fungicides planting increased the rice yield by 6.9%compared with the conventional crop fertilization planting. AMF complex fungicides can effectively promote the growth and improve the yield of rice. Compared with traditional crop fertilization, AMF complex fungicides have the advantages of zero fertilization, low cost and high yield, and can enable clean rice production and solve the problem of non-point source pollution in rice fields.
