Recently, some vegetable farmers have reported that soon after the weeds in vegetable fields have been cleared, many weeds grow on the ground. This is very troublesome. In order to save time, many people began to use herbicides to control weeds. However, vegetables are very sensitive to herbicides and care must be taken when applying herbicides.
First, pay attention to the effect of herbicides on squat vegetables
Most of the vegetables are very sensitive to herbicides. Improper application is likely to cause phytotoxicity, especially herbicides with a longer duration, and it is also easy to affect the squat vegetables. Therefore, we must pay attention to the application of herbicides, not only to consider the growth of this vegetable, but also consider whether it will affect the growth of manure, etc., so as not to cause losses.
Second, pay attention to the types of vegetables in the application of selective herbicides
For example, in the control of grassy weeds in broad-leaved vegetable fields such as gourd and cucumber, high-efficiency flupirtine, quizalazine and other broadleaf vegetable herbicides can be used. When herbicides are sprayed, they must be strictly followed according to the instructions for use. For example, when the soil is used by the vegetable farmers, the use of sulfamethoxal is more effective.
Although some herbicides are safer, if applied after the colonization of vegetables, it is best to spray with a directed sprayer to avoid spraying on vegetable plants.
Third, the application of herbicides must be to relieve the characteristics of herbicides
Short-lived, contact-killing herbicides, such as paraquat, can only be absorbed by plant green tissues, causing them to die, and they can quickly combine with the soil and passivate in the soil, without affecting the squat vegetable. Apply before vegetable colonization. However, such herbicides can only kill the aerial parts of the weeds and have no effect on the underground stems and roots of the weeds. Weeding is often incomplete, so weeds are still numerous during planting. Farmers can combine other measures to prevent and control weeds better.
One is weeding and weeding. This is the most beneficial method for weeding crops. By turning the land with a hoe and other tools, it can not only eliminate the roots but also loosen the soil, which is conducive to the rooting of the vegetable roots at the seedling stage and plays an important role in cultivating strong trees.
The second is to cover the black mulch. The main function of the black plastic film is to prevent the grass. Now the temperature in the greenhouse is high, and the weeds reproduce very quickly. After covering the black plastic film, we no longer need to worry about the weeds. The autumn black mulch is a good weeding measure, but it is better not to cover the black mulch when it comes to wintering vegetables. Because the winter season is low, the black mulch is not conducive to the increase of the ground temperature. It is best to cultivator before covering the black mulch to increase the permeability of the soil.
