随着生产条件的改善和产量要求的提高,因地制宜地采用适宜的播种方式,是获得高产的基本措施之一。目前,我省平坝地区多采用窄行条播;丘陵粘土和湿田地区则正大力推广小窝点播。七十年代以来的高产栽培实践指出,窄行条播植株分布比较均匀,有利于分蘖早生快发,但群体不易控制,行间通风透光不好,容易发生倒伏。北方和长江下游麦区的一些高产单位,采取适当放宽行距或采用宽窄行,效果较好,我们这里是否也应如此?丘陵粘土地区采用小窝点播有利于密植匀播,保苗增穗,获得显著增
With the improvement of production conditions and the improvement of yield requirements, proper sowing methods are adopted according to local conditions, which is one of the basic measures for obtaining high yields. At present, Pingba area in our province mostly adopts narrow-strip broadcasting; hilly clay and wet-field areas are promoting small-hole on-demand broadcasting. The practice of high-yield cultivation since the seventies pointed out that narrow-rowed sowing plants are more evenly distributed and are conducive to rapid early tillering, but the population is not easy to control, and the ventilation between the rows is poor and the lodging is prone to occur. Some high-yielding units in the north and the lower reaches of the Yangtze River, using appropriate width spacing or width and width lines, the better, we should also be here? Hilly clay planting area using small on-site planting is conducive to close planting, seedling by ear, significantly increase
