| 摘 要： | 通过4个沟垄集雨处理对旱地燕麦前期水热状况及发育期的影响进行了试验研究。结果表明,处理T3可以显著的提高作物耕作层的水分,显著高于处理T1。处理T1地温的日变幅最大(8.8℃),处理T3最小(5.8℃)。处理T3与T4的出苗率最高,分别为67.88%和65.85%,显著高于处理T1(49.51%)。处理T3到达苗期的发育期最短(22d),显著小于处理T1(29d)。可见,处理T3可以显著地提高作物生育前期的土壤水温条件,提高出苗率及缩短作物的发育期。 |

| Abstract: | The effects on the water and heat of early stage and the developmental phase in dry land oats were studied with 4 different treatments.The results showed that ①T3 treatment could significantly improve the non-plough layer of crop water,and was higher than the T1 treatment.②The biggest amplitude(8.8 ℃) in each day was appeared in T4 treatment,and T3 treatment was minimum(5.8 ℃).③Germination rates of T3 and T4 treatment were 67.88% and 65.85%,and significantly higher than the T1 treatment of 49.51%.④T3 treatment had the shortest period(22 d) in seedling stage and significantly less than T1(29 d).So,T3 treatment could significantly improve the soil moisture and temperature of crop growth condition,raise seeding rate and shorten the developmental phase of crops. |
