控害丰产栽培技术是自然控制病虫害的重要因素。经过6年的试验研究及3000多亩的示范,表明水稻“低群体、早追氮、增磷钾、适施穗肥等”的配套栽培技术,能稳定稻田生态系统在常态下病虫种群较低的密度,减轻病虫发生为害和提高稻谷产量,真正实现预防为主,以农业防治为基础防治水稻病虫害,达得经济、安全、高效的目标。
Control of high yielding cultivation techniques is an important factor in the natural control of pests and diseases. After six years of experimental research and a demonstration of more than 3,000 mu, it shows that the cultivation techniques of rice “low population, early chasing nitrogen, increasing potassium and applying panicle fertilizer, etc.” can stabilize the population of pests and diseases in paddy ecosystem under normal conditions Low density, alleviating the pests and diseases and increasing the output of paddy, truly realizing the prevention and controlling pests and diseases of rice on the basis of agricultural prevention and control, achieving the goal of economy, safety and efficiency.
