【摘要】 为评价有机无机复混液体肥对棉花产量与品质的影响，研究有机无机复混液体肥与化肥对棉花产量与部分纤维品质的影响。统计试验田（施用有机无机复混液体肥）与对比田（施用化肥）棉花产量，并测定其品质。在产量方面，试验田棉花产量低于对比田，但差异不显著(P>0.05)；在品质方面，试验田棉花纤维长度、衣分均高于对比田，较对比田棉纤维和衣分平均增加5.03%、1.19%，试验田与对比田的棉花马克隆值无统计学差异(P>0.05)。2种肥料在不同示范区对棉花马克隆值和公制支数的差异不同，在新湖县和106团，施用复混肥棉纤维马克隆值低于常规施肥，而在乌苏县高于常规施肥；马克隆值与公制支数呈负相关关系，影响与马克隆值相反。有机无机复混液体肥能满足棉花生产需要，相比常规施肥籽棉产量略低，但可以增加衣分，对皮棉产量的影响小；其次可适当增加棉纤维长度，提高棉纤维品质。更多还原

【Abstract】 To evaluate the effects of organic-inorganic compound liquid fertilizer on cotton yield and quality,we studied the effects of organic-inorganic compound liquid fertilizer and chemical fertilizer on cotton yield and some fiber quality. We compared the cotton yield in the test plot(application of organic-inorganic compound liquid fertilizer) and the control plot(application of chemical fertilizer) and tested cotton quality.The results showed that: the lint yield of the test plot was lower than that of the control plot with no significant difference(P>0.05). In terms of quality, the cotton fiber length and lint in the test plot were higher than those of the control plot, and increased by 5.03% and 1.19%, respectively. The micronaire value of cotton in the test plot and the control plot had no statistical difference(P>0.05). The micronaire value and metric count of cotton were different under the application of the two fertilizers in different demonstration areas. In Xinhu County and Regiment 106, the micronaire value of cotton fiber under the application of compound fertilizer was lower than that under conventional fertilization, but it was the opposite in Wusu County. The micronaire value had a negative correlation with the metric count, and the effect of fertilizer on metric count was opposite to that on micronaire value. Compared with conventional fertilization, the organic-inorganic compound liquid fertilizer application had a slightly lower seed cotton yield, but it increased the lint content and had little impact on the lint yield. In addition, the organic-inorganic compound liquid fertilizer could appropriately increase the length of cotton fibers, improve the quality of cotton fibers, and meet the needs of cotton production.更多还原
