一九六一年,我们对棉花不同密度及其打顶早晚等八个试验处理,按照夏尔达可夫所介绍的小液流法,进行了细胞吸水力的测定。一、从第一次测定(在早打顶后第六天,晚打顶前五天)中可以看出:1.不论密度大小,凡是未打顶的细胞吸水力都比早打顶的细胞吸水力大;2.密度相同,末打顶的强胞吸水力均大于早打顶的细胞吸水力; In 1961, we tested the cell’s water uptake by eight test treatments, including different densities of cotton and the sooner or later topping, according to the small flow method described by Shaldakov. First, from the first test (in the morning after the first six days, late top five days) can be seen: 1. Regardless of the density of the size, those who did not hit the top of the cell water than the early topping cells Water absorption; 2. The same density, end topping of the strong cell water absorption were greater than the early topping cell absorption;
