一、每亩要种多少株木薯原系热带作物,需要充足的阳光才能使薯块长大。将木薯种在荫蔽的地方,就会徒长茎叶,叶序稀疏,节间加长,茎细,薯小。因此,过度密植,将会违反木薯的生理要求,达不到丰产目的,但是,过度稀植,每亩株数过少,不能充分利用地力,同样也达不到丰产目的。

First, how many strains per acre to plant cassava original tropical crops, need plenty of sunshine to make tubers grow up. The cassava species in shade, it will be lengthened stems and leaves, sparse leaf sequences, internodes lengthened, thin stems, small tubers. Therefore, over-planting will violate the physiological requirements of cassava and will not reach the goal of high yield. However, excessive sparse planting, with too few trees per mu, can not make full use of the fertility and also fail to achieve the goal of high yield.
