采用田间取样与试验室分析相结合的方法,调查研究了阿拉尔垦区密植枣园土壤养分状况,选取7个土壤养分指标:碱解氮、速效磷、速效钾、全氮、全磷、全钾、总盐,应用多元统计分析方法,分析了阿拉尔垦区密植枣园土壤养分含量的状况及差异性。结果表明:阿拉尔垦区各团场密植枣园土壤养分中全氮、磷、钾、全氮、全磷、全钾养分含量存在明显的差异,同一团场不同土层的全氮、磷、钾、全氮、全磷、全钾养分含量均呈现逐步递减的趋势。由土壤含盐量看出阿拉尔垦区土壤呈碱性,六团、七团相对其它各团密植枣园土壤中的含盐量较高,建议六团、七团在红枣采摘结束后,入冬前的冬灌水采用漫灌的方式,可压盐使土壤含盐量降低,有利于提高产量。
Using the method of combining field sampling and laboratory analysis, the soil nutrient status of dense planting jujube orchards in Alar reclamation area was investigated. Seven soil nutrient indexes were selected: alkaline hydrolysis nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium , Total salt, the application of multivariate statistical analysis methods, analysis of the Alar land reclamation area close to jujube orchard soil nutrient content of the situation and differences. The results showed that there was a significant difference in the contents of total nitrogen, phosphorus, potassium, total nitrogen, total phosphorus and total potassium in the soil nutrients of the densely-planted jujube orchard in Alar reclamation area. The content of total nitrogen, , Total nitrogen, total phosphorus, total potassium nutrient content showed a gradual decline. Soil salinity from the soil showed Allah reclamation soil alkaline, six groups, seven groups relative to the other groups close planting jujube garden soil salt is higher, it is recommended six groups, seven groups in the red picking after the end of winter The winter irrigation before the use of flood irrigation methods, salt can make the soil salt content is reduced, is conducive to increasing production.
