近年,我县双季晚稻全面推广了“先控后促”育秧法,提高了秧苗素质,解决了晚稻秧田长草和难拔秧的问题。它比旱育、水播水育、夹层秧田先促后控等育秧法出苗快而整齐,播后两天三夜全部出土现青,五天时间秧苗可达一叶一心。具体做法是:秧田施有机肥如青蒿、红萍等,及早水整水做,使泥烂无硬块,以利于做平秧墁,又可起到养草灭草作用。播种前排水澄田,先开好四周围沟,再分墁耥平,待秧墁达到手捺有窝显指纹的硬度即可播种。播前先催芽到破嘴露白即可。边播边塌谷,以谷不见
In recent years, the county double-season late rice comprehensively promoted the “first control and then promote” nursery method to improve the quality of seedlings to solve the late rice seedling long grass and difficult to pull the seedling problems. It is faster than dry nurturing, water sowing and watering, mezzanine seedling first post-emergence control and other nursery seedlings emergence fast and neat, two days and three nights after sowing are all unearthed, five days seedling up to one leaf and one heart. The specific approach is: seedling organic fertilizer such as Artemisia annua, red duckweed, water as early as the water to make the mud rot without lumps, in order to facilitate the flat seedlings, but also play the role of grass weed control. Drainage before sowing Chengtian, first opened a good around the ditch, sub-sub-Huan Ping, until the seedlings Yang hand to hold a nest of significant fingerprints hardness can be planted. Sowing before breaking to reveal the white can be exposed before sowing. Sowing edge of the valley, not seen in the valley
