在进行水稻高产栽培、新品种选育以及品种特征特性等研究方面,常常需要测量叶面积。但目前还缺乏定型的可供使用的测量仪器,须要采用一些简易有效的测量方法。为此,我们于1977年在调查水稻品种剑叶的同时,对几种简易测量叶面积的方法,作了一些比较研究。我们在测量水稻多品种不同形状叶面积的过程中,选用了不同叶型(包括长短、宽窄各种组合的12个品种,有籼、粳稻,高、矮秆),每个品种随机取剑叶3—4片,采用三种方法分别测量叶面积:(1)
It is often necessary to measure the leaf area for high-yielding cultivation of rice, selection of new varieties and characterization of varieties. However, there is still a lack of stereotypes for the use of measuring instruments, the need to use some simple and effective measurement methods. To this end, in 1977 we investigated the flag leaf of rice varieties at the same time, several simple method of measuring leaf area, made some comparative studies. We used different leaf types (including 12 varieties with various combinations of length, width and width, indica, japonica, high and dwarf) in the measurement of leaf area of different shapes of rice variety. Each variety randomly selected the flag leaf 3-4 tablets, using three methods were measured leaf area: (1)
