以晋麦43号为材料,对3种覆膜条件下,旱地冬小麦产量及光合特性的研究表明:不同覆膜方式下其产量为地膜穴播>条播盖苗>膜侧条播>露地条播(对照)。覆膜处理的净光合速率及气孔导度高峰期比对照提前,地膜穴播和膜侧条播小麦增产潜力大,灌浆期的净光合速率下降慢,蒸腾速率、气孔导度、灌浆速度等生理指标都显著高于条播盖苗和对照。
Taking Jinmai 43 as material, the yield and photosynthetic characteristics of winter wheat under three kinds of plastic film mulching conditions were studied. The results showed that the yield of plastic film mulching was mulching> mulching mulching> film mulching> . The net photosynthetic rate and stomatal conductance of the plastic film mulching treatments were earlier than that of the control, and the potential of plastic film mulching and film mulching was higher than that of the control, and the net photosynthetic rate decreased slowly at the filling stage. The transpiration rate, stomatal conductance and filling speed Significantly higher than the seedling and seedling control.
