【摘要】 微孔膜小麦在冬前、拔节期有较好的生物学效应 ;在小麦全生育期有较好的温度效应 ;有效抑制了土壤水分的无效蒸发 ,较好地满足了小麦主要生育阶段水分需求 ,水分生产效率 (1 0 4 1kg/mm)较对照提高 39 5% ,产量达 4 4 6 1kg/hm2 。更多还原

【Abstract】 Dibbled wheat in microporous film had better biological effects before winter and at shooting stage compared with the control. It showed better temperature effects in the whole growing season as well. This technique effectively prohibits soil water evaporation and meets water requirements of wheat growth and development in a more effective way. Water use efficiency of this technique reaches up to 1.041 kg/mm, 39.5% higher than the control. The yield reaches up to 4 461 kg/ha.更多还原
