| 对稻茬烟田杂草定点调查发现，草害参数与烟叶产量损失率呈ｙ＝Ａ＋Ｂｘ直线回归关系，并求出当地生产水平下杂草经济防除阈值模型： |
| 英文摘要: |
| The authors studied bionomics and the yield loss of weeds in tobacco field of rice stubble by placement investigation, The results showed that the relationship between weeds parameter and yield loss of tobacco was the straightline regression: y=A+Bx.Thus a economic threshold model of weeds control based on local production level was established,that was : |
