为研究同一个核桃品种在管理水平基本相同、气候条件一致的情况下,坚果饱满程度差异较大的原因,对阿克苏地区红旗坡农场九分场和二分场核桃园里温185核桃果实成熟过程中土壤性质的变化进行了分析。结果表明:二分场核桃园土壤保水能力较好、水溶性盐分含量较低。九分场核桃园土壤中的水溶性盐分含量较高,6月份土壤电导率为0.60mS·cm-1、8月份为0.55mS·cm-1,比适应范围(0.11~0.24mS·cm-1)高出2~3倍;其它营养元素都在适应范围之内,但是核桃仁不饱满情况较严重,这可能是由于水溶性盐分影响其它物质的吸收引起的。
In order to study the reason why the same walnut varieties have the same management level and the same climatic conditions, Changes in soil properties were analyzed. The results showed that the water retention capacity of walnut in two-stage field was better and the content of water-soluble salt was lower. The water-soluble salt content of soil in Jiufen field was higher, and the soil conductivity in June was 0.60mS · cm-1 and 0.55mS · cm-1, which was higher than the adaptive range (0.11 ~ 0.24mS · cm -1 ) Were 2 ~ 3 times higher than other nutrients were within the scope of adaptation, but walnut incomplete situation is more serious, which may be due to water-soluble salts affect the absorption of other substances caused.
