| 摘 要： | 在分析植棉紫色土养分对棉花营养影响的基础上,讨论了土壤养分对棉花纤维品质的作用.比强度、2.5％跨距长度、伸长度、麦克隆值和整齐度五个纤维品质指标中,前三者与土壤养分显著相关.土壤养分中对纤维品质影响较大的是微量元素硼、铜及大量元素磷、钾,其中以硼和铜与棉花纤维品质的关系最为密切.

| Abstract: | The pot-culture experiments were conducted under coditions of natural soil fertility for successive 3 years with several types of cotton-planting purple soils in Sichuan Province taken as experiment materials. The effects of the soil nutrients on cotton fibre quality were discussed on the basis of analysing the influence of the soil nutrients on cotton nutrition. Among 5 fibre quality indices including Strength,Length,Elong,Mike and Uniformity,the 3 former were affected by the soil nutrients. The effect of the soil nutrients is characterized by the following: 1. The microelements played an important role in affecting cotton fibre quality. 2. The macronutrients gave rise to certain effect on cotton fibre quality but the effect was in the minor place . 3. Of the microelements, B and Cu of the soil were the most important factors affecting cotton fibre quality. The results further showed that Cu and K of the soil exerted a positive influence on cotton fibre quality, whereas B of the soil presented a negative effect. The reason for this kind of B behavior was possibly that B of the soil brought about antagonistic effect on such elements as Mo and N. |
