摘要
新修梯田马铃薯沟种较平作、垄作产量分别提高 11.1%和 15.9% ,产值分别增加 7.9%和 2 3.6% ,追施 N肥可使产量和产值分别增加 2 0 .3%和 15.7% ;追施保水剂可使产量和产值分别增加 31.2 %和 46.8% ;喷施多效唑 (Multiple- effect triazole,MET)可使产量和产值分别增加 2 9.7%和 58.0 %。
The yield of potato with furrow planting could be increased by 11.1% and 15.9%, and the output values increased by 7.9% and 23.6% respectively compared with that by flat and ridge planting in newly built terraced field. With additional fertilizer of nitrogen, the yield and output value of potato increased by 20.3% and 15.7%. The experiment results also showed that additional application of moisture keeper could increase the yield by 31.2% and output value by 46.8% and MET(a plant growth regulator) could increase the yield by 29.7% and output value by 58.0%.
