The Effects of Soil Difference on Fiber Quality of Midlle-longstaple Cotton

The fiber quality influenced by soil fertility were studied in two experimental fields during two years.The results showed that: The effects of different soil fertility on strength and length of cotton fiber is difference in different cultivar;and on elongation or micronaire is more stability than strength and length;the more responsibility between heredity genes and meteorological conditions,and more difference effects of different soil fertility on fiber quality components,especially on strength and length.
