| 摘 要： | 通过室内花盆试验,研究了在相同条件下,小麦粉碎秸秆、MP3005保水剂、扩蓄肥3种水分抑蒸剂施入土壤后,对土壤水分蒸发量的影响.结果表明,3种水分抑蒸剂都能达到抑制土壤水分蒸发、提高水分利用率的目的,且抑蒸效果随用量不同而异.抑蒸效益分析表明,小麦秸秆在抑蒸量为8 000.4 kg/hm~2,MP3005保水剂在抑蒸量为1 600.08 kg/hm~2,扩蓄肥在抑蒸量为4 000.2 kg/hm~2时抑蒸效益最好. |

| Abstract: | In this paper,indoor pot experiments were conducted to study the effects of three evaporation-inhibiting agents,wheat straw smash,MP3005 aquasorb and store-extending material on soil moisture evaporation. The results showed that all these three agents can inhibit soil evaporation and increase water use efficiency,and the effect of soil water-inhibition varied with the amount of evaporation-inhibiting agents applied. The benefit analysis shows that the best efficiency can be achieved when 8 000.4 kg/ha wheat straw smash,1 600.08 kg/ha MP3005,4 000.2 kg/ha store-extending material were applied. |
