提高水稻单位面积产量的方法策略,以前已有许多研究者从各种角度进行了探讨。结果使产量有了显著的增加。但是近年来,单位面积的产量上升的趋势有达到高峰的苗头,继续处于停滞状态。水稻高产的技术因素,据以前所阐明的条件有:适当的栽植时期、培育壮苗、密植、深耕多肥、加入肥的客土、增施堆肥、改进土壤透水性等。但是这些技术及条件,虽在各种土地上获得高产是要的,然未归纳出统一系统的栽培原理。松岛氏将水稻产量分解为穗数、每穗颖花数、结实率及千粒重四个要素,并阐明其形成过程。还
Methods and strategies for increasing yield per unit area of rice have been explored by many researchers from various angles. The result is a significant increase in output. However, in recent years, the trend of the increase in output per unit area has reached a peak, continuing to be at a standstill. The technical factors for high yield of rice, according to the conditions previously clarified: appropriate planting period, nurturing strong seedlings, close planting, deep plowing and more fertilizer, adding fertilizers to the soil, composting, improve soil water permeability and so on. However, although these technologies and conditions are necessary for obtaining high yields on various kinds of land, the principle of cultivation of a unified system has not yet been summarized. Matsushima’s decomposition of rice yield into spikes, spikelets per spike, seed setting rate and grain weight four elements, and clarify the formation process. also
