Weeding target One is to kill the axillary bud that has sprouted before the leeches, and float on the surface of the field after the water smashes. The second is to kill the alfalfa seeds that can be quickly germinated on the surface of Honda and in the depth of 1 cm before and after transplanting. These two forms of valerian, competing with the rice seedlings after transplanting the seedlings, are difficult to control by conventional herbicide techniques. Technical points Selection and dosage of pharmaceuticals: 60% despicamine, 60% butachlor, according to the density of grass seeds, the amount of hectares used is between 0.5 and 0.75 kg. Application period and method: When the water is leveled, the water is leveled and evenly applied. Precautions Uniform application: use an empty bottle to divide the medicine according to the area of ​​the Honda pool. After the water is combined with the mechanical water leveling, the application is carried out (the mixed water application is longer than the clear water application). Interval: The interval between the application of the herbicide and the transplanting shall be separated by 3 days after the application, and the transplanting of the seedlings at 4 to 5 days is better. It is necessary to transplant the seedlings while transplanting, how much can be inserted, how much is transplanted, and not sent. If the transplanted Honda lacks water, it can be replenished normally. The interval between seedling quality is determined: the interval between seedlings and health can be shorter, otherwise the interval is extended by 1~2 days. Adaptability of rice varieties: For some new rice varieties, after application, it is suitable for local rice varieties with strong adaptability. Foliar fertilization promotes slow seedling: 1~2 days before sputum, can spray potassium dihydrogen phosphate and nitrogen-containing foliar fertilizer to the seedbed, which is beneficial to slow seedlings. Combined with conventional weeding: After the early closure of the mites, when the transplanting rafts are 5~7 days, the seedlings are slowly removed, and after the new roots are removed, the water can be immersed 3~4 cm deep (inch water layer). Combined with conventional herbicide technology. The use of this closed mites technology, combined with conventional medication, can receive the desired results.
