研究了小麦干旱寄种技术的可行性与增产效应。结果表明 :萌动发芽的小麦种子在干旱的砂姜黑土内 ,断水 4 0d ,出苗率仍可达到 73.4 %～ 85 .4 %;寄种小麦的增产效果取决于供水时间 ,在断水 4 0d内 ,供水时间愈晚 ,增产效果愈加明显 ,寄种 2 0d ,增产幅度达 6 .8%。
The feasibility and yield increasing effect of wheat drought-inoculation technology were studied. The results showed that germinating germinated wheat seeds could reach the rate of 73.4% ~ 85.4% in 40 days of dry sago soil after the water was cut off, and the increasing yield of the wheat was dependent on the water supply time. Within 40 days of water-cut, The later the water supply, the more obvious the effect of increasing production, send 20d, increase rate of up to 6.8%.
