【摘要】 <正> 小窝密植,是川西丘陵黄壤粘土地区在传统的小麦窝播(穴摇,点播)技术基础上逐步加以改进,于七十年代前期形成的一种播种方式,具有显著优越性。由于过去把这一播种方式仅仅看成是在不便条播的特定土质条件下的一种适宜播种方式,因而未能在土质条件较好的条播麦区加以试验推广。七十年代中期以来,毗邻黄壤粘土区的川西平原,随着生产条件的显著改善,小麦生产上普遍采用的窄行条播,虽然具有土地直更多还原

【Abstract】 The research was conducted in the West Plain of Sichuan Province in 1978—1982. Results showed that the close small hill planting of wheat is a good planting method, which obtained a higher yield of wheat than by the narrow or wide drilling method due to the evenly developing of number and weight of spikes per unit. The main factors affecting the increase of yield by this method were analysed.更多还原
