| 摘 要： | 通过对怒江干热河谷区荔枝园内不同耕作模式土壤表层水分含量的动态变化进行比较分析后发现,灌水后1~40 d,树盘未覆盖和行间清耕的土壤表层含水量比树盘覆盖和生草覆盖的土壤含水量下降快,灌水40 d土壤表层水分含量树盘覆盖>生草覆盖>树盘未覆盖>行间清耕。荔枝园的空气温度与湿度成负相关,与4个处理土壤表层含水量成显著负相关;空气湿度与4个处理土壤表层含水量成正相关。

| Abstract: | According to the comparisons and analysis on the surface soil moisture content dynamic variation among the different cultivation modes in litchi garden in dry-hot valley of Nujiang,it’s found out that,after irrigation 1 d to 40 d,the surface soil moisture of no-mulching and clean tillage drop faster than mulching and grass cover.After irrigating 40 d,water content of surface soil under different tillage modes is as following :mulching> grass cover>no-mulching>clean tillage.The air temperature is negative related to air humidity in Litchi garden,and has significant negative correlation with the surface soil moisture of four treatments.The air moisture has positive correlation with the surface soil moisture of four treatments in Litchi garden. |
