| 摘 要： | 本文分析了地膜覆盖条件下,土壤耕层积温的变化对玉米根系及地上植株生长影响的生理基础.同时对传统的“蹲苗”措施进行了讨论.指出蹲苗是播种后土壤耕层温度持续偏低导致幼苗缓慢生长,不得已而采取的措施.实际上是延迟性冷害的表征.

| Abstract: | The physiological basis in the influence of the cumulative temperature change of plough layer on the corn root system and plant growth in condition of plastic film mulching was analysed in the paper, and the traditional measure to restrain the seeding growth was discussed. Auther indicated that restraining seedling growth is a measure had to be taken when the temperature of plough layer is continuously so low that seedling growsh slowly. Infact, this is a symbol of lasted cool damage. |
