1) hay covered
干草覆盖
1.
The results show that: in the whole evaporation process,soil evaporation of 100% hay covered is the smallest.
通过在希拉穆仁草原典型地带进行不同干草覆盖下的土壤蒸发实验,结果表明:在蒸发过程中,覆盖干草阻止了水分的垂直蒸发,提高了土壤湿度,降低了土壤的蒸发速度,延长了有限土壤水的持续期,且土壤蒸发量随着覆盖度的增加而减小,盖度为100%的土壤试样蒸发量最小。
2) rice straw covering
稻草覆盖
1.
The results showed that for all treatments,the emergence rate of conventional model was the highest,the total yield and yield of per plant of micro-tillage with 8 cm-thick of rice straw covering was the highest,and the commodity rate of potato for no-tillage with 8 cm-thick of rice straw covering was the highest.

干草
hay
gonC00干草(hay)含水量在17%以下的牧草通称干草。生产中，为防止霉变，干草宜在水分低于巧%下贮存。历史上干草生产的意义在于解决草食家畜冬季饲料不足问题，现代畜牧业生产条件下，干草及其加工产品已经作为包括猪、禽在内的舍饲家畜全年需要的饲料之一。 依据干燥过程特点，干草分为天然干草与人工干草。天然干燥的干草常可以干草捆方式收贮，用于草食家畜生产。人工干草依干燥过程使用温度不同分为常温通风干燥(鼓风机常温鼓风干燥)、低温烘干(干燥温度50~70℃)、高温快速干燥(进风口温度9以)~1 100℃)3类，依形态特征而有青干草、草粉、草颗粒、草饼、草块之分。 决定干草品质的重要因素包括成熟度、牧草种类、化学组成、茎叶比例、物理形态、异物、收贮期间干草损坏变质状况、有毒有害成分的存在与否。 发达国家干草生产总量趋于稳定或有所下降，远东地区、特别是东南亚地区对于草产品的需求则趋于扩大。中国干一巍 大型垛草机(王培摄)草生产体系尚处于建设阶段，在满足国内需求和出口创汇方面前景广阔。
