Is there any way to weed permanently?

Except that the land is not used for planting (for example, cement laying, salinization), there is no permanent method of weeding. The commonly used artificial, mechanical, chemical and other weeding methods can only remove weeds for a while, not permanently. When weeding, pay attention to the following points:

1. Pull weeds by hand and use simple farm tools to weed. The utility model has the advantages of high energy consumption and low work efficiency, so it can not be prevented in time in a large area. Now it is used as an auxiliary means to remove local residual weeds after weeding with other measures.

two。 Weeding machines and tools driven by animal power or mechanical power. Generally, mechanical ploughing, harrowing and soil mulching are carried out before sowing, before sowing or at seedling stage, so as to control the occurrence and harm of weeds in farmland. High work efficiency and low labor intensity. The disadvantage is that it is difficult to remove weeds between seedlings, not suitable for intercropping or close planting conditions, and frequent use can also cause soil consolidation in the plough layer.

3. The use of water, light, heat and other physical factors to weed. For example, the method of prairie fire is used to reclaim wasteland and weed, the method of flooding is used to control xerophytic weeds, and dark plastic film is used to cover the soil surface to block the light, so as to increase the temperature for weeding.

When using herbicides to control weeds, we should pay attention to the safety of the operators and strictly follow the instructions to avoid drug damage.
