【Abstract】 Soil and nutrient rapid measurement recommended fertilization technology for irrigated rice is an important integrated management technology measure of modern agricultural rice production, with significant fertilizer-saving, expenditure-saving, yield-increasing, income-increasing, environmental protection and other advantages. In this paper, the technical specification of rapid measurement and recommendation of soil and nutrients for irrigated rice were introduced from the aspects of rapid measurement recommended fertilization technology for irrigated rice, recommended amount of nitrogen, phosphorus and potassium fertilizer and other supporting technologies. This technology can reduce the amount of chemical fertilizer application and improve the utilization rate of chemical fertilizer, which is an effective way to realize the green development of rice in Southwest South China.更多还原
