How to weed the film by covering the vegetable fields

In recent years, vegetable mulching cultivation has developed rapidly. The cost is low, the effect is quick, and the effect of increasing production is significant. Because the plastic film has the functions of heat preservation, water conservation, and fertilizer maintenance, the growth rate of weeds in vegetable fields is also faster than that of ordinary open cultivation. The following two measures can be adopted to timely remove weeds: Improve the quality of plastic film coverage. The quality of mulching film is directly related to the effect of increasing production. For the cultivation of crops covered with mulch, early preparation should be made. The soil should be plowed early, organic fertilizer should be applied as base fertilizer, and fine soil preparation should be used to achieve deep ditch sorghum (ditch size at least one foot) for drainage and irrigation. Covering the plastic film must be tightened and flattened to close to the ground. If the cover film is of poor quality, it is not only easy to ventilate and leak air, but also has poor insulation, water retention and fertilizer retention, and it also promotes the growth of weeds. Second, promote the use of herbicides. The transplanted vegetables were sprayed with butachlor Herbicide before filming, which had a good weed removal effect.
