第二次土壤普查后,我县开始应用垄畦栽培技术改良冷水烂浸中低产田,至1992年全县推广面积达2万多亩,水稻增产显著。近年来,因种粮比较效益差,农民种粮积极性下降,我县垄畦栽培技术应用面积逐年减少。1997年,在垄畦栽培技术基础上,试验研究垄畦稻沟坑鱼技
After the second soil census, the county began to apply ridge cultivation techniques to improve the low-temperature and low-yielding cold-paddy fields. By 1992, the popularization area of the county reached more than 20,000 mu and the yield of rice increased significantly. In recent years, due to the relatively poor efficiency of grain cultivation, farmers’ enthusiasm for grain cultivation decreased, and the area of ridge ridge cultivation technology in our county decreased year by year. In 1997, based on the cultivation techniques of ridge cultivation, the experiment was conducted to study the technique of ridge ditch pit ditch
