| 摘 要： | 通过大田试验,研究膜上不同水分亏缺灌溉对制种玉米产量的影响。结果表明,制种玉米在抽穗—灌浆期适度水分亏缺灌溉有利于提高籽粒产量,并能满足制种玉米对水分的需求。膜上适度调亏灌溉有利于增产,提高水分生产效率。

| Abstract: | Irrigation system for corn under the membrane field test data,examined the growth of different levels of soil water deficit on seed yield of maize.The results showed that seed corn in the filling of the water deficit treatment is more conducive to the transfer of photosynthetic to grain and seed corn to meet the demand for water,the higher value,less water consumption per unit of production,irrigation water,better efficiency.Thus,in the film proper irrigation water deficit conditions,but there is increasing effect,as compared with conventional surface irrigation,membrane,water-saving irrigation system for corn to about 20%. |
