Herbicidal ether: Jiangtian weeding is more used, commonly used 25% herbicide ether wettable powder, mainly by spray method or toxic soil method for soil treatment. The spray method uses about 1 kg of herbicide ether per acre, and is added into 100 kg of clear water to prepare a liquid. After the ginger is sown, the soil is moistened and the liquid is evenly sprayed on the ginger ditch and the surrounding ground. Pay attention to the reverse operation when spraying, and keep the ground moist after spraying. The toxic soil method is fully mixed with 1 kg of herbicidal ether and 15-20 kg of wet non-sticky soil per acre, and stacked with plastic film for 10-14 hours to allow the medicament to be fully absorbed by the soil. Spread the poisonous soil evenly on the ginger ditch and the surrounding ground. The operation should be reversed.
Weeding pass: use 33% of weeding emulsifiable concentrate 150-180 ml per acre, add 60 liters of water, spray on the ginger before sowing. Sand land use needs to be reduced.
As the growth of the ginger plants is getting better and better, the weeds are getting more and more prosperous. It is not suitable to use a chemical herbicide at this time. In the case where the ginger plant has grown, there is no corresponding selective herbicide registered on the ginger, so the artificial method can only be used for weeding. If it is necessary to weed with chemical agents, the use of glyphosate and other directional sprays to prevent weeds around the ginger, although it has a certain effect, it is very easy to damage the ginger plants (must use a protective cover to prevent the liquid from splashing onto the ginger leaves), At the same time, repeated application of glyphosate is effective, so it is generally not recommended to use chemical agents to weed after the growth of ginger.
