查询词典 mulch

Effect of water saving was studied under no-tillage with straw mulch, conventional tillage with straw incorporatedand conventional tillage on bare ground. The results showed that NTS increased soil water storage by 30.6 mm and 23.9 mm over CTS and CTB during summer fallow.

对免耕覆盖、秸秆还田和常规耕作在休闲期的节水效果研究表明：在夏季休闲期，免耕覆盖比常规耕作多贮水30.62 mm，比秸秆还田多23.91 mm；在冬季储水灌溉期间，可将储水定额从2 100 m3/hm2减少到600和975 m3/hm2。

Based on the existing work, we give the detailed introduction of factors, such as soil texture, wind velocity, vegetation, crop stubble mulch, soil moisture, terrain, artificial factors and so on. We also elaborate the quantitative relation between all related factors and wind erosion amount. At last, we summarize the exiting wind erosion controlling measures. The main purpose of this paper is to provide some references for experiment studys on wind erosion of soil and putting forward feasible controlling measures.
