水稻跨熟期栽培技术探讨

Study on Multi-guard Methods of Rice Forwarding Culture Technique

多保护方式跨熟期栽培技术研究试验结果表明，采用双棚旱育苗技术较生产上单棚大棚旱育苗技术可增加有效积温66.78℃，结合适当合理密植、中优施肥及使用促早熟药剂等方法的应用可延长生育期5～6d，对于实现目前特定生态条件下水稻品种的再一次越区种植、进一步提高单产是有效的。

The result of multi-guard methods of rice forwarding culture showed that active temperature of double plastic-house increase 66.78℃ than a single plastic-house,and raise growing period 3-5 d by proper close plants, adequate fertilizer and chemicals of forwarding mature. So it is effective to raise unit yield in a special nature ecological condition again.
