摘要：【中文】本发明公开了一种直播甜菜田除草方法，其包括苗前除草和苗后除草。本发明的优点在于，打破了二甲戊灵禁用于甜菜田的局限，将其用于直播甜菜田苗前封闭除草，不仅不会造成甜菜药害的问题发生，而且提高了直播甜菜田苗前封闭除草的效果，对于禾本科杂草防效达100％，对于双子叶杂草防效达95％以上，对多种单子叶杂草、一年生莎草及部分一年生双子叶杂草有较高防效。在有效的苗前封闭除草的基础上，在苗后杂草出现时，利用苗后除草剂进行化学除草，有效控制禾本科杂草、双子叶杂草以及4叶以上杂草，提高直播甜菜田杂草防效；除草方法简单、便捷、易操作，无需采用不同的除草剂反复进行除草操作，亦可达到较为理想的杂草防治效果。 【EN】The invention discloses a weeding method for a direct seeding beet field, which comprises pre-emergence weeding and post-emergence weeding. The invention has the advantages that the limitation that pendimethalin is forbidden in a beet field is broken, the pendimethalin is used for closed weeding before seedlings in a direct seeding beet field, the problem of beet phytotoxicity is not caused, the closed weeding effect before seedlings in the direct seeding beet field is improved, the control effect on gramineous weeds is 100 percent, the control effect on dicotyledonous weeds is more than 95 percent, and the pendimethalin has higher control effect on various monocotyledonous weeds, annual sedge and part of annual dicotyledonous weeds. On the basis of effective pre-emergence closed weeding, when the post-emergence weeds appear, the post-emergence herbicide is used for carrying out chemical weeding, gramineous weeds, dicotyledonous weeds and weeds with more than 4 leaves are effectively controlled, and the weed control effect of the direct seeding beet field is improved; the weeding method is simple, convenient and easy to operate, and can achieve ideal weed control effect without adopting different herbicides to carry out weeding repeatedly.

摘要：【中文】本发明公开了一种直播甜菜田土壤封闭用除草剂及使用方法，除草剂包括如下质量百分比的组分：96％金都尔乳油70‑72％，33％二甲戊灵乳油28‑30％；使用方法包括S1.配制除草剂、S2.除草剂稀释、S3.除草剂喷洒。本发明的优点在于，打破了二甲戊灵禁用于甜菜田的局限，提高了直播甜菜田土壤封闭除草效果，对于禾本科杂草防效达100％，对于双子叶杂草防效达95％以上，对多种单子叶杂草、一年生双子叶杂草有较高防效。使用方法简单、便捷、易操作，无需反复进行除草操作，亦可达到较为理想的杂草防治效果。 【EN】The invention discloses a herbicide for closing soil in a direct-seeding beet field and a use method thereof, wherein the herbicide comprises the following components in percentage by mass: 70-72% of 96% of golden Du missible oil and 28-30% of 33% of pendimethalin missible oil; the using method comprises S1, herbicide preparation, S2, herbicide dilution and S3, herbicide spraying. The invention has the advantages of breaking the limitation that pendimethalin is forbidden in a beet field, improving the soil closed weeding effect of a direct seeding beet field, having the control effect on gramineous weeds of 100 percent and dicotyledonous weeds of more than 95 percent, and having higher control effect on various monocotyledonous weeds and annual dicotyledonous weeds. The application method is simple, convenient and easy to operate, repeated weeding operation is not needed, and a relatively ideal weed control effect can be achieved.
