本课题是在多年测土配方施肥的基础上,应用回归最优设计对水稻进行有机与无机肥经济最佳配比施用技术研究。试验结果采用微机PC—1501运算,最终得出在不同土壤肥力下的汕优佳33达到的目标产量
This project is based on years of soil testing and fertilizer on the basis of the application of regression optimal design of organic and inorganic fertilizers in rice for the best economic application of technology research. The test results using PC-1501 computing, and ultimately come to different soil fertility Shanyou 33 to achieve the target output
