草木樨对降雨的利用率相当高,因而使土壤水分消耗较多。生育期内根系在水平方向上的吸水范围达50厘米,在垂直方向上可达100厘米。收籽后,耕层土壤墒情恢复特别快,而底层恢复相当慢。因此,草木樨的后作物应安排需水较少的浅根系作物为宜。
The utilization rate of vegetation is very high, which makes the soil water consume more. During the growth period, the root system has a water absorption range of up to 50 cm in the horizontal direction and up to 100 cm in the vertical direction. After harvesting, top soil moisture regained particularly fast, while the bottom recovery is quite slow. Therefore, it is advisable to arrange shallow plants that require less water after the crop.
