| 摘 要： | 通过对夏玉米在露天和干旱棚控水2种土壤水分状况下生长状况的观测,发现秸秆覆盖夏玉米有明显增产效应,作物水分利用效率均得到了不同程度提高。通过对0、3000、6000、9000、12000 kg/hm2五种处理下玉米状况的对比,得出6000 kg/hm2为渭河平原地区最适宜夏玉米田秸秆覆盖量。在6000 kg/hm2覆盖量下,露天小区夏玉米可增产5.61%。试验证明,渭河平原地区秸秆覆盖夏玉米,增产潜力大,是一种值得推广的玉米增产措施。

| Abstract: | Through conversation of the maize growth under the rain-shelter and open space,it can be concluded that maize yield can be increased obviously and the water use efficiency of crop can also be improved.It is found that 6000 kg/hm2 is the best covering amount for the maize in Weihe plain through the comparison of the summer maize under the 0、3000、6000、9000、12000 kg/hm2 straw mulch covering,The maize yield can be increased by 5.61% and the water use efficiency can be increased by 4.39% respectively under the 6000 kg/hm2 covering.So it can be concluded that the straw mulch covering to summer maize can increase yield and it is a way that worth expanding. |
