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
The small densely populated forest is gradually improved on the basis of the traditional wheat planting (hole shaking, on-demand) technology in the yellow soil clay area of the western Sichuan hills. A sowing method formed in the early 1970s has obvious advantages. In the past, this method of seeding was only considered as a suitable sowing method under certain soil conditions which were inconvenient to sow. Therefore, it failed to be popularized in experimental areas with better soil conditions. Since the mid-1970s, in the western Sichuan plain adjoining the yellow clay region, with the significant improvement in production conditions, the widespread use of narrow row strips in wheat production has been achieved,
