How about weeding in ginger field?

How about ginger field weeding? Please give guidance to the growth of ginger, there are a large number of weeds and ginger seedlings for fertilizer, water, sunlight, so that ginger seedlings do not get normal nutrition and poor growth, resulting in yield reduction. Therefore, in the seedling stage, timely weeding is an important management measure, but manual weeding, labor intensity and more labor, in recent years with chemical herbicides to eliminate weeds, has been more and more widely used in production. Chemical weeding, good effect of weeding, simple and easy, not only can reduce labor intensity, but also save labor, but also can keep the countryside clean, reduce the occurrence of pests. At present, herbicide ether is widely used in ginger field, mainly spraying method or poisonous soil method for soil treatment. Spraying method is: 0.75~ 1kg herbicide ether per mu, first add a small amount of water to mix evenly, then add water to dilute to sufficient amount, generally add about 100 liters of water per mu, prepare liquid medicine, after ginger sowing, take advantage of the wet soil, spray the liquid medicine evenly on the beautiful ditch and the surrounding ground, pay attention to backward operation when spraying, prevent stepping on the ground to destroy the soil surface medicine film, affect the weeding effect. After spraying, it should be kept fully moist, and the weed control effect can generally reach more than 85%, which is safe and harmless to ginger seedlings. Poison soil method: 0.75~ 1 kg herbicide per mu, first sprinkle the pesticide on a small amount (2~25 dry grams) of fine soil, so that the soil and medicine are fully mixed, or first dissolve herbicide in a small amount of water, and then spray the liquid medicine on a small amount of fine soil, mix evenly, and then expand the amount of soil, usually 15~25 kg of pre-screened semi-dry and semi-wet fine soil per mu, fully mixed, stacked for 10~14 hours, so that the pesticide is fully absorbed by the soil. After planting ginger, the poison is evenly sprinkled on the ginger ditch and the surrounding ground. In the process of application, the poison soil should also be applied backwards to prevent damage to the drug film. Benifenin has killing effect on all kinds of annual weeds in vegetable field. Within 5 days after application, the killing effect on weeds was the strongest, and after 5 days, the killing effect gradually decreased, and the efficacy generally lasted for 30~40 days. In order to keep the United States and Japan clean, after the first application, apply herbicide once every 35 days or so according to the above method, which can basically control the occurrence of weeds in the seedling stage. After ginger enters vigorous growth period, the plant has been closed ridge, weed occurrence gradually reduced. Herbicidal effect of herbicide ether is closely related to environmental conditions such as temperature, soil moisture and illumination.① Generally, when the temperature is above 20℃, the weeding effect is good, and when the temperature is lower, the weeding effect is poor. Therefore, the dosage of herbicide should be different according to the temperature, in warm weather, 0.75 grams per mu can be used, in mild weather, 1 kg per mu can obtain better control effect. (2) Light conditions also have an effect on the weeding effect. In general, the stronger the light, the better the weeding effect. For example, under dark conditions, herbicide has almost no weeding effect. Soil moisture conditions are often critical to the success or failure of herbicide use. The soil surface is wet, and the weeding effect is good. If the soil is dry, the weeding effect will be greatly reduced. Therefore, after applying herbicide, it is necessary to keep the soil surface wet frequently to improve the weeding effect.
