Abstract

Abstract:

In order to explore the effects of different mulch types (normal mulch, biodegradable mulch, liquid mulch) and different irrigation amounts (6 000, 4 500, 3 000 m³·hm^-2) on photosynthetic parameters, yield and quality of cotton, a two-factor experiment with randomized block design was carried out. It was shown that the average soil temperature in 0-25 cm layer was significantly (P<0.05) increased with normal mulch and biodegradable mulch, as compared with the treatment without mulch. The photosynthetic capacity, yield and quality of cotton was relatively better with the irrigation amout of 6 000 m³·hm^-2 under all much types. Compared with the treatment without mulch, the cotton yield was significanlty increased by 19.97% and 21.15% with biodegreadable much and normal mulch, respectively. Given the photosynthetic capacity, yield and quality of cotton, the biodegradable mulch showed no signifiant adverse effect compared with the normal mulch. Therefore, the biodegradable mulch was feasible to replace the normal mulch to reduce the white pollution in cotton production. Correaltion analysis and gray correlation analysis results revealed that the SPAD value, transpiration rate, stomatal conductance, net photosynthetic rate were signifiantly positively correlated with the micronaire, fiber length, uniformity index and yield per plant. SPAD value showed the highest gray correlation with micronaire, maturity, lint percentage. Tranpiration rate showed the highest gary correaltion with yield per plant. Stomatal conductance showed the highest gary correaltion with fiber length and uniformity index. Net photosynthetic rate showed relatively higher gray correlation with micronaire, uniformity index and yield per plant. Thus, these four indexes (SPAD value, transpiration rate, stomatal conductance, net photosynthetic rate) could be further used as important indicators to evaluate the effect of mulch type and irrigation amount on cotton yield and quality.

Key words: biodegradable mulch, irrigation amount, photosynthetic physiological parameter, fiber quality
