抛秧是一项水稻轻简化栽培技术,有序化栽插是抛秧稻稳定高产和进一步超高产的基础。本试验通过摆栽、点抛、撒抛3种抛栽方式以及新型秧盘培育稻株的光合物质积累特性的比较,旨在研明水稻有序化栽插超高产的光合物质积累特性,并探索水稻超高产新模式。有序摆栽和点抛群体起点质量高,发棵快,各生育时期群体叶面积、粒叶比、光合势、物质生产、积累、后期剑叶光合速率和物质转运均优于撒抛,后期通风透光性好,仍能保持较强的物质生产和抗倒伏能力,最终产量高。二连孔、三连孔栽插较单孔减少1/3~1/2,提高了栽插速度。三连孔稻苗前期活棵较快,二连孔稻株中、后期表现出较强的优势,能保持较强抗倒伏和群体物质生产能力,最终产量表现为二连孔稻株大于三连孔和单孔,三连孔和单孔稻株间差异不显著。有序摆抛栽稻群体起点质量高,活棵快,前期有着适宜的光合物质积累和叶面积,后期保持较强的光合物质生产、积累和转运能力,是实现超级稻稳定超高产的基础,二连孔稻株整个生育时期均表现出较强的物质生产和生长优势,三连孔稻株也具有一定优势,二连孔、三连孔有序摆抛栽是一种水稻省工超高产栽培新模式。
Throwing rice is a simplified light rice cultivation techniques, orderly transplanting throwing rice is the basis of stable high yield and further super high yield. The purpose of this experiment was to compare the characteristics of photosynthetic characteristics of three rice varieties planted by throwing, throwing, throwing and throwing, Exploring a New Model of Super High Yield Rice. The results showed that the population growth rate was higher than that of the control group. The results showed that the population growth rate was higher than that of the control group Good ventilation and ventilation, can still maintain a strong material production and lodging capacity, the final high yield. Erliankan, triple-hole planting than the single-hole reduction of 1/3 to 1/2, increased planting speed. The seedlings of Sanlian-Kong rice seedlings were faster in early prophase, and the plants of Erlian-Kong rice plants showed stronger advantages in the later period, which could maintain strong lodging resistance and material production ability of the population. The final yield was higher than Sanlian There was no significant difference between holes and single hole, triple hole and single hole rice. The orderly rice throwing and planting rice population has high starting point, fast live trees, suitable accumulation of photosynthetic material and leaf area in the early stage, and strong production, accumulation and transport ability of photosynthetic substances in the late stage, which is the basis for achieving super- Erlian hole rice plants throughout the growing period showed a strong material production and growth advantages, three even hole rice plant also has some advantages, Erlian hole, Sanlian Kong ordered pendulum throwing planting is a super-high yield of rice province workers Cultivation of new models.
