摘要
通过理论分析和田间实验研究,推导出三江地区水稻插秧期适时性损失函数,同时获得该地区的最佳插秧时间。为水稻全程机械化实施的插秧机的配备提供了有价值的基础数据,对提高水稻生产机械化的经济效益,有着十分重要的实际意义和应用价值。
The function of rice planting season timeliness in the Sanjiang zone was derived through theory analysis and field test research. In the meantime, coefficient of timeliness loss and optimum time of transplanting rice seedling were obtained. Valuable basic data for the allocating of transplanter, which was done to realize the rice production through mechanization, were given by these results. It has very important practical significance and applied value for improving the economic efficiency of the rice production mechanization?
