Abstract:

The wide and narrow row spacing cultivation of rice improved the field microclimate and the utilization ratio of light energy per unit area, thus achieved the effect of increasing yield. The 2ZG-8 self-propelled high speed rice transplanter, which was developed according to the wide and narrow row spacing cultivation technique of rice, changed the traditional planting mode, improved the microclimate in the field, at the same time increased the planting density reasonably, not only increased the yield, but also improved the quality of rice. It makes the high-efficient agronomic technology become the actual productivity through mechanical materialization, and opens a new era of rice cultivation.

Key words: rice wide and narrow row spacing, field microclimate, yield, high efficiency, productivity, solar energy use efficiency
