Abstract
Determined cotton leaf area index and other canopy characteristics in full growing period under mulch drip irrigation of the conventional irrigation fertilization,optimized cotton irrigation,optimized fertilization,and analyzed the dynamics of cotton canopy structure and its relationship with yield.The results showed that: conventional fertilization with N and P in the conventional irrigation could make the cotton LAI(Leaf area index) value and MFIA(Mean foliage inclination angle) value significantly increase,TC(Transmission coefficient for diffuse penetration) value and T(Transmission coefficient for radiation penetration) value significantly reduced,which can make the number of bolls per unit area and boll weight significantly increase,and then led to the seed cotton yield significantly increased;N,P,K balanced fertilizer can make the cotton LAI value and MFIA value slightly decreased,reduce TC value and T value,which can increase boll number and then improve seed cotton yield.In conventional fertilization,reducing water amount,optimizing irrigation frequency and irrigation water of the growth period can increase the cotton LAI value and MFIA value,reduce TC value and T value,which can increase boll weight and then make seed cotton yield significantly increased.
