Abstract: A large-scale test demonstration of the integrated technology of“synchronized side-deep fertilization technology of machine-transplanted rice + green prevention and control of diseases and insect pests” was carried out in late rice production in Hunan. Compared with the control area of “conventional fertilization + green prevention and control of diseases and insect pests”, the demonstration area achieved higher partial productivity of nitrogen, phosphorus and potassium fertilizers on the basis of reduced fertilizer application by 10.3% and reduced nitrogen fertilizer application (N) by 15.9%. At the same time, the grain yield was increased by 63.7 kg/667 m2, the quality of rice is better, and the income increased by 85.4 yuan/667 m2. The technology of green prevention and control of diseases and insect pests ensured the safety of grain. This technology realized green, high-quality and efficient production of rice.

Key words: rice, synchronized side-deep fertilization technology of machine-transplanting, green prevention and control technology, fertilizer reduction, fertilizer partial productivity, yield
