The problem of weeding in Chengdu landscaping projects often focuses on the growth period of ground cover plants. Once the maintenance is not in place, weeds are prone to disaster, because the ground cover plants in the green space often make ribbons or even reading glasses for plant varieties of different families and genera, and the cost of manual weeding is often too high, so many chemical herbicides should be used with caution.
What does "three plants" mean? Spraying the closed herbicide "Henaisi" one week before planting after the micro-topography of the green land is formed can generally successfully solve the problem of overgrowth of weeds in the slow seedling stage of ground cover seedlings, and generally prevent weeds such as most grasses from breeding.
What is "seven-point maintenance"? Sharp-leaved weeds are also the most troublesome weeds in the greening and maintenance period. Manual weeding is often incomplete, and weeds need to be weeded every month during the growth and reproduction period, which is costly, while conventional chemical reagents are generally easy to damage or even die seedlings. After many years of practical operation, it has been proved that spraying clear water on seedling plants immediately after spraying a green land with "Maocaojing" can effectively solve the problem of weeds in 3-7 tip leaves. Prevention is the main way of green space conservation, and the combination of prevention and control is often ideal. We can try to sprinkle closed herbicides on the green space where the seedlings have been planted with colored blocks. In practical application, the ideal application effect is to spray wet fine sand with "spreading ice" and spread weeds directly by hand, which can generally propagate through seeds for 2-3 months.
