近年来,我场推广双季连作杂交水稻早造采用温床育秧,获得良好效果。温床育秧可提早播种,全年主动,产量高。在一九七六年倒春寒严重的年份里,我们用温床育秧和大田薄膜育秧,同种在一个土质、肥力、管理相同的槽田中,结果,温床育秧增产 In recent years, our field to promote double cropping continuous hybrid rice as early as the use of hotbed nursery, get good results. Hotbed seedling can be sown early, take the initiative throughout the year, high yield. In the severe winter in late spring in 1976, we nurtured seedlings with hotbed and field film seedlings in the same tillage with the same soil quality, fertility and management. As a result, hotbed nursery plants increased yield
