麦后早稻插秧迟,大田营养生长期短,前作消耗地力颇大。为了争取高产稳产,必须十分注意培育壮秧。为此,采用正交法开展多点试验,探讨秧龄、播种量和起秧方式等因素对产量影响的规律,结果明确:一、麦后早稻选用迟熟品种培育适龄大苗,弥补大田营养生长的不足,是夺取高产的关键之一。据紫泥公社农科站、巧山生产队和南屯大队试验,同日插秧,迟熟品种大苗比早熟品种小苗,每亩增产176～243斤。 Late rice transplanting late rice, malpractice growth period is short, before consuming a lot of ground force. In order to strive for high and stable yield, we must pay great attention to cultivating strong seedlings. Therefore, using orthogonal test to carry out multi-point test to explore the law of seedling age, sowing rate and seedling raising and other factors affecting yield, the results are clear: First, the late rice after maturity selection of late maturing varieties of seedlings to make up for nutritional growth Insufficient, is one of the keys to winning high yield. Purple Farm commune Agricultural Station, Qiaoshan production team and the Nantun brigade test, the same day transplanting, late maturing varieties of seedlings than the precocious seedlings, an increase of 176 to 243 pounds per mu.
