沙壤土条件下土壤含盐量对棉花生物学特性和产量的影响

摘要

The variation of cotton growth under the condition of drop irrigation between low-salinization sandy soils and salin-ization sandy soils was mainly studied through comparison on the number of leaves, plant height, numbers of fruit spur and bolls numbers of cotton. The preliminary results showed that the biological characteristics of cotton in low-salinization sandy soils were better than that in salinization sandy soils; and the yield in low-salinization sandy soils was relatively higher.%为研究新疆棉田膜下滴灌棉花在低盐碱沙壤土(对照田)和盐碱沙壤土(试验田)两种情况下棉花生长发育的变化,对叶片数、株高、果枝层数、始果节高度及结铃数的变化进行了分析比对,初步得出低盐碱沙壤土上的棉花各生物学特性较盐碱沙壤土上的优良,最终产量也更高.
