摘要
山西大同地区从5月下旬到6月下旬均可播种苦荞,但不同播期对苦荞籽实产量影响较大。适时早播可有效利用当地的水、热、光等自然资源,提高苦荞单位面积产量,促进当地苦荞生产。推迟播期,生育期明显缩短,籽实产量显著减少,主要经济性状也随着播期的推迟而减少。
Datong region from late May to late June buckwheat can be planted, but the different sowing dates on seed yield of buckwheat larger. Timely and effectively take advantage of early sowing of water, heat, light and other natural resources, increasing yield per unit area buckwheat, buckwheat and promote local production. Delayed sowing, growth period was shortened, seed yield was significantly reduced. With the major economic traits also reduced the delayed sowing.
