| 摘要: |
| 麦茬直播陆稻田草害的控制,我们自1982年起连续三年进行了生产实践和试验研究,结果初步表明:1.根据麦茬直播陆稻田杂草的生物学和生态学特性,杂草化学防除应立足于芽后土壤兼茎叶处理的策略。2.在壤土,肥水条件和管理水平较高的地区,实行覆盖免耕结合化学和生态等综合防除措施,省工高效,增产增收,一举多得。3.播后芽前土壤处理,只有在整地质量和墒情都好的条件下运用效果好。 |

| A PRELIMINARY WEED CONTROL STRATEGY FOR THE DIRECTLY SEEDED UPLAND RICE AFTER WHEAT |
|
|
|
| Abstract: |
| Practice and experiments in fields have been conducted for three years to study the better weed control strategy for upland rice after wheat.The results are as follows: 1,Weed control should be based upon the strategy of soil with foliar application of herbicides after weeds emerged according to the biological and ecological charactors of weeds in directly seeded upland rice after winter wheat. 2,It is much better when using the no-till mulching with the combination of chemical,ecological,and other integret... |
