新疆阿拉尔垦区密植枣园土壤养分含量调查与分析
Survey and Analysis of the Soil Nutrient in Close Planting Jujube Gardens in Alar Area
摘要
Abstract
The soil nutrient status of close planting jujube for the Alar area was investigated in this paper with the method of field sam -pling and laboratory analysis .Seven indicators of soil nutrient including Alkali Solution Nitrogen ( ASN ) , Available Phosphorus (APH), Available Potassium (AP), Total Nitrogen (TN), Total Phosphorus (TPH), Total Potassium (TP), and Total Salt (TS) were analyzed with Multivariate statistical analysis .And the result shows that there were significant differences for TN , ASN, APH, AP, TPH, and TP in all the jujube close planting gardens across all the regiments of the Alar area , and showed a gradual decreasing trend in different layers at the same garden .The content of Salt shows that the soil in Alar is alkaline , and the TS of jujube close plant gardens are higher in 6th and 7th regiments than the others .So it is recommended that flood irrigation as the winter irrigation before the winter in the 6th and 7th regiments should be taken to reduce the salt contents and increase jujube yields .关键词
