新疆绿洲土壤中的水溶态硼和硼肥效应探讨
摘要
前言微量元素硼
主要浓集在硅酸盐中
地壳的所有岩石中都含有硼
在地壳中其丰度为10ppm。世界各地由于生物气候、化学地理条件的不同
土壤中硼含量的差异较大。新疆是全国最干旱的省区
其中少数地区又属世界极端干旱区。新疆各地几乎全是地球同纬度上降水量最少的地方。这种干旱的气候条件
必然对新疆土壤中一些元素的累积迁移产生独特影响。
Abstract
The water-soluble boron eontents in oasis of soil of Xinjiang range from 0.17 to 75 ppm and the mean is 2.56 ppm. The contents of water-soluble boron are as follow: south of Xinjiang>east of Xinjiang>north of Xinjiang. The level of water-soluble boron in the topsoil is higher than the subsurfure soil. The content of water-soluble boron in the soil group of dilfferent soil geograhical condition are as follow: Yermosols>Xerosols>Castanozems。
