摘要

应用土壤养分状况系统研究法．1996-2002年在新疆4个主要棉区，采集21个点的主要类型耕层土壤．通过土壤分析、吸附试验和盆栽试验。系统地研究新疆主要棉区土壤的养分状况、土壤对主要养分的吸附固定能力和生物有效性，结果表明：各营养元素的缺乏顺序．和田灌淤土为N＞P＞Zn＞K＞Cu＞S，阿克苏潮土和灌淤土为N＞P＞Zn＞K＞Mn＞Fe＞Cu。喀什潮土为N＞P＞Zn＞Cu＞Fe．石河子灰漠土是N＞P＞Zn＞S＞Fe＞Cu＞Mn。

Abstract

Cultivated layer soil samples were collected in 21 plots from main soil types in 4 cotton production areas in Xinjiang province and the soil analysis

soil adsorbing trials and pot experiments were conducted in 1996~2002 to study soil nutrient element status

the adsorbing ability of soil to nutrient elements and the bio-availability of nutrient elements by systematic approach systematically in main cotton soil types

the main results are as follows:the order of nutrient elements deficiency was N>P>Zn>K>Cu>S in Irrigated soil in Hetian area

N>P>Zn>K>Mn>Fe>Cu in Damp soil and Irrigated soil in Akesu area

N>P>Zn>Cu>Fe in Damp soil in Kashi area and N>P>Zn>S>Fe>Cu>Mn in irrigated gray desert soil in Shihezi area.
