The Report of Technology of Mix-space-transplanting Cultivation of RiceⅠ. Theory of Increasing Yield of Mix-space-transplanting Cultvation of Rice

摘要:

采用不等株行距的宽窄行混合和等穴距错位插秧的混合稀植栽培形式, 研究了边行效应在混合稀植栽培中的作用、混合稀植栽培的产量表现、组成行的产量、边行效应值及增产机理。该栽培技术体系综合了目前普通等株行距稀植和超稀植栽培的优点, 通过边行效应进一步挖掘增产潜力。

Abstract:

This artical reported the style of mix-space-transplanting cultivation, e. g. mix line and hole distance or mix line with staggered transplanting cultivation, mechanism of action of marginal effect in the mix-space-transplanting cultivation, yield of different mix-space-transplanting cultivation forms, the mechanism of increasing yield and marginal effect value of the composition line in the mix-space-transplanting cultivation. This technology system synthesizes the advantage of eqaul line and hole distance space transplanting and extraspace transplanting cultivation and through the using of the system the yield potential could be digged.
