[Methods] Such five in-fIuencing factors as Iine spacing, pIanting density, nitrogen （N）, phosphorus （P） and potassium （K） of fodder soybean seeding in autumn idIe Iand were compared using orthogonal experiment method and LSD method of PASW 18 statistics software. [Results] The resuIts showed that density, Iine spacing and K2O had important ef-fects on bioIogical yield of fodder soybean in autumn idIe Iand. Moreover, the opti-mum proposal for high-yield matching cuItivation technique of fodder soybean in au-tumn idIe Iand was determined as foI ows： pIanting density was 75 ＆#215;104 pIants/hm2;300 kg/hm2 N, 112.5 kg/hm2 P2O5 and 375 kg/hm2 K2O were viewed as basic fertiIiz-ers; the seedIing styIe was sowing in driI with the Iine spacing of 50 cm. In the proposal, fresh and hay grass yields were 6 661.67 and 2 723.64 kg/hm2, respec-tiveIy, which increased by 24.17% and 27.63% respectiveIy compared to the second fine combination. [Conclusions] The resuIts provided a theoretical basis and technical support for the production of fodder soybean in autumn idIe Iand.展开更多

From the perspectives of dry matter production, nutrient absorption, sink and source, pho-tosynthesis, graln fiI ing and roots, the eco-physioIogical characteristics and high-yielding cuItivation techniques of super hybrid rice in China were discussed. In addi-tion, the probIems that restricted the high and stabIe yielding of super hybrid rice were analyzed, and the deveIopment directions of high-yielding cuItivation techniques for super hybrid rice were also discussed.展开更多
