1991~1996年边续几年采用水稻主要品种在不同气象、不同氮肥条件下的抗病性鉴测试验研究和大田系统调查,整理分析陆良县前24年历史资料,掌握稻瘟病发生规律,成功的组建陆良穗瘟发生趋势预测式:Y1=1.41275+0.6573X1+2.3317(9-X2)-1.5433X3+2.20743X4.1994~1996年连续在3.43×104hm2(次)稻田上进行预报应用,预报精度达76.9%~94.75%.节约用工11.7万个.减轻群众负担90.2万元.挽回稻谷12427t,纯增人民币1147.96万元,取得了显著的经济、社会和生态效益.使预防穗瘟达到新水平,是陆良病虫害预测从经验(定性)预测走向数量化(定量)预测的新开端
From 1991 to 1996, several years later, the main rice varieties under different meteorological conditions and different nitrogen conditions were used to study the disease resistance test and field system investigation. The historical data of the past 24 years in Luliang County were collected and analyzed to determine the occurrence rules of rice blast, The success of the formation of Lulium paniculata trend prediction formula: Y1 = 1.41275 + 0.6573X1 + 2.3317 (9-X2) -1.5433X3 +2.20743X4.1994 ~ 1996 forecast of 3.43 × 104hm2 (paddy field) , Forecast accuracy of 76.9% ~ 94.75%. Saving 117,000 jobs. Reduce the burden on the masses 902,000 yuan. Recover 12427t of paddy, a net increase of 11.4796 million yuan, has made significant economic, social and ecological benefits. The prevention of frostbite to a new level is the new beginning of luliang pest prediction from empirical (qualitative) prediction to quantitative (quantitative) prediction
