1 材料与方法供试种子是收获后经种子加工厂烘干使水分降到14%的干燥种子。供试种子机械分级,按种子扁度分为1,2级(即扁1级,扁2级),按园度分为1,2级(即园1,园2),以不分级种子为对照,即混合种子。 2 试验方法 2.1 田间设计。试验采取随机区组法排列,4次重复,行长10米,行距60厘米,穴距40厘米,每小区150株(穴)垧保苗41500株,播种同时施用磷酸二铵,(200公斤/垧),不施有机肥,收获时全区收获,经机械烘干水分降至14%,然后脱粒,称重。 2.2 试验条件。①试验地地势平坦,肥力均匀黑壤土,并旱涝保收,不受外界侵害的地块。②试验地用
1 Materials and methods The tested seeds were dried seeds harvested and dried in a seed processing plant to reduce the water content to 14%. The test seed mechanical grading, according to seed flatness is divided into 1, 2 (ie, flat 1, flat 2), according to the garden is divided into 1, 2 (ie Park 1, Park 2) Control, that is, mixed seeds. 2 test methods 2.1 field design. Randomized block test was used to arrange 4 repetitions with a length of 10 meters, a row spacing of 60 cm, a hole spacing of 40 cm and 150 cells per cave (point) ), No organic fertilizer, harvested when the region harvested, the mechanical drying water down to 14%, and then threshing, weighing. 2.2 Test conditions. ① Test ground flat, fertile black soil evenly, and Hanlaobaoshou, from the outside world of land. ② experimental use
