摘要
针对石灰岩丘陵土层浅薄、干旱缺水的主要问题 ,在坡改梯的基础上 ,测定了不同旱作保水技术措施的土壤含水量、土壤物理性状、土壤水文状况、土壤养分含量、土壤水分特征曲线、土壤导水率和土壤有效水含量等综合指标。结果表明 :其旱作保水效果为覆膜 >保水剂 >覆草 >松土 >对照 ;对寒露蜜桃产量和质量综合评价为覆膜 >覆草 >保水剂 >松土 >
In order to change the situation of lean land and drought in limestone hill,studied and measured some comprehensive indexes under the different dry farming and water retention treatments.The results showed that the sequence of water retention effect of different treatments is: cover with veil>water retention preparation>cover with grass>lossen soil>check;the sequence of the effect to Hanlu honey peach's yield and quality is: cover with veil>cover with grass>water retention preparation>loosen soil>check.
