| 摘 要： | 研究了固定道龙作条件下,不同生育时期内春小麦土壤水分变化及其产量.结果表明:不同栽培措施下,0～30 cm土层,固定道垄作在拔节前土壤含水量较高;30～60 cm土层,其在整个生育期内土壤含水量下降8.55%,下降幅度最大,表现了良好的供水性;60～90 cm和90～120 cm土层,固定道垄作在全生育期内均保持较低的土壤含水量.其产量较传统提高11.25%,水分利用效率达15.59 kg/(mm·hm~2).

| Abstract: | The field experiment was carried out to study changes in soil moisture and production in spring wheat under permanent raised bed (PRB). Results showed that soil moisture under PRB was higher in 0 -30 cm layer ;in 30 -60 cm layer,soil moisture decresed noticeably under PRB during the whole stage,declined 8.55% and showed a good supplication of water;in 60 -90 cm and 90 -120 cm layer,soil moisture under PRB was lower. It's production compares the tradition to enhance 11.25% ,the water using efficiency reaches to 15.59 kg/(mm·ha) |
