| Abstract: | This paper reviewed the key diagnostic index and optimized regulating route of high yield population quality about mulch drip irrigation cotton. The diagnostic indices are as follows: the great ability of crop apparent photosynthesis(CAP) and proper leaf area index(LAI), high accumulation and distribution of dry matter, high total boll numbers per area, high ratio of boll numbers to leaf area under reasonable LAI, et al. It is very important that regulating techniques of water fertilizer and chemistry hormone have already been used to mulch drip irrigation cotton. |
