Abstract: Micro area locating method was used in this test in order to study the effect of different no-till straw mulch amount on soil moisture in no-till soybean field. The results indicated that: As the straw mulch amount increased, the changes of soil moisture also increased in different soil layers treatments during different growth stages. The average soil moistures in different no-till straw mulch amount treatment of 0%, 30%, 60% and 100% are all higher than the conventional ridge culture treatment. The average increase range was from 0.99% to 3.77%. The 100% straw mulch treatment had the best water conservation effect in all the treatments; After straw mulch, the surface soil of no-till soybean in the early growth stage had significant water inrichment phenomenon. Compared to the conventional ridge treatment, the soil moisture of 5cm soil layer increased in different no-till straw mulch treatments by 4.81% to 9.43%.
