在晚稻两矮病预测模式y=(n·d·p·t)/x应用中,预测因子d值(黑尾叶蝉带毒率)的快速检测是个关键技术问题,在以往实验里我们采用血清学方法得到较好的解决。但在目前农业科技条件下,血清学方法只能由部分科技部门所掌握,县以下广大农业生产部门暂时还不能直接推广应用。因此为使两矮病预测模式能作为党规测报技术在生产
In the application of prediction model d = (n · d · p · t) / x for the two-dwarf disease prediction model for late rice, the rapid detection of the predictor d value (the infection rate of the rice leafhopper) is a key technical issue that we used in previous experiments Serological methods have been better resolved. However, under the current conditions of agricultural science and technology, serological methods can only be mastered by some science and technology departments, and the vast agricultural production departments under the county level can not be promoted and applied directly. Therefore, in order to make the two dwarf prediction models can be used as the party rules and forecasting technology in the production
