How to use chemical weeding in rice seedling field? Please introduce chemical weeding in rice seedling field to save labor, labor and good effect. However, in production, if it is not used properly, it will produce drug damage, and in serious cases, it will destroy the seed and rebreed. Therefore, in addition to the seedling field, it is necessary to master the following techniques: different methods of raising seedlings, different herbicides and different methods of use. At present, there are two methods of raising seedlings in production, one is water raising (wet raising), the other is dry raising. Dry cultivation and chemical removal technique: after sowing and covering soil, 42% butachlor was used in every 66.7 rice seedling field. Oxazone 10ml, mixed with water for 4 times, was sprayed on the soil and closed, and then the peritoneum was sprayed. Chemical removal technology of water-raised seedlings: during the chemical removal period, when the seedlings grow to the 2-leaf and 1-heart stage, withdraw from the surface water layer of the field, every 66.7 years of seedling field, with 36% benzyl. 5 grams of dichloride, 4 murals of water and 5 grams of water, spray on the seedling field. Note: ⑴ solution must be sprayed evenly, not re-spraying and leakage spraying; ⑵ dry seedling field herbicide must not be used in water seedling field, otherwise it will cause serious drug damage.
