近年来,随着晚稻面积的扩大,栽插晚稻季节人力、畜力紧张,少数社队采用少耕栽培技术,收到了良好的效果。为此,我们开展了晚稻少耕栽培技术试验和调查研究。试验方法 (一)稻田类型和少耕方式对晚稻产量的影响试验。试验在本所实验场和永川何埂基点进行。同田各处理的品种、播栽期、施肥水平和田间管理一致。小区面积0.1亩(“泸晚4号”为200平方尺),重复3次,随机排列。稻田类型:①紫色冲积田。肥力中上等,前作冬水田栽早稻,泥足8寸左右。②紫泥冲田(大泥田)。肥力中上等,质
In recent years, with the expansion of late rice area, planting man-made late rice season, animal power shortage, a small number of communes to use less tillage cultivation techniques, received good results. To this end, we conducted a trial of late rice cultivation techniques and research. Test methods (A) paddy field types and less tillage methods on the yield of late rice experiments. Experiments in our laboratory and Yongchuan Hoh Chuen base point. The variety, sowing date, fertilization level and field management of each treatment in Tongtian are consistent. Community area of 0.1 acres (“Lu night on the 4th” to 200 square feet), repeated 3 times randomly arranged. Paddy field type: ① purple alluvial field. Fertility in the finest, before the winter paddy field planted early rice, mud foot 8 inches or so. ② purple mud red field (large muddy field). Fertility in the finest, quality
