    摘要:

    采用盆栽模拟方法,研究残膜对玉米出苗及幼苗根系伸长的影响,结果表明,残膜的存在对玉米出苗率与根系伸长具有一定的抑制作用。土壤中普通地膜的残膜造成玉米出苗率低、出苗慢、根系穿透地膜的几率小,将会影响到玉米植株地上部的生长发育。降解地膜的残膜虽然对玉米出苗率及根系伸长也略有影响,但与普通地膜相比,对玉米出苗及根系伸长危害较小,且随着播种后时间的推移,这种危害逐渐消失。

    Abstract:

    The effects of plastic film residue on emergence and root growth of corn seedlings were studied by pot experiments. The results showed that the plastic film residue had certain inhibitory effect on corn seedling emergence and root growth. Ordinary plastic film residue reduced the rate of maize emergence. The corn seedling germinated slowly. Corn seedling roots could hardly penetrate through the plastic film. Ordinary plastic film residue had effect on the aboveground growth and development of corn. Compared with ordinary film,degradable plastic film residue also had certain inhibitory effect on corn seedling emergence and root growth,but the harm to corn growth was less and disappeared as time passed.
