地膜一段育“三苗”与我省近年推广的地膜两段育秧相比,具有节省劳动力、简化育秧工序、降低育秧成本等优点。而且还可将栽秧期提早,延长本田营养生长期和促进分蘖早生快发,提高水稻单位面积产量。据我所多年试验和示范资料,地膜一段育秧比地膜两段育秧每亩平均增产稻谷20.8公斤,增3.71%。因此,逐步改地膜两段育秧为地膜一段育秧,实行三秧三田配套。即一般水源条件较好的膀田,浅脚冬水田

Plastic film a period of “three Miao” and the province in recent years to promote the two sections of film mulching, compared with the saving of labor, simplify the nursery, reduce the cost of raising seedlings and so on. But also the planting seedling earlier, to extend the vegetative growth of Honda and promote early tillering faster, improve rice yield per unit area. According to my many years of experiments and demonstration data, a section of plastic film seedling growing more than plastic film mulching two acres of rice average yield of 20.8 kilograms of rice, an increase of 3.71%. Therefore, the gradual change of filming two sections of seedlings for plastic filming seedlings, the implementation of three seedlings supporting Mita. That is, the general conditions of the best water fields, shallow winter paddy fields
