In garden nursery cultivation, weed control is an irreplaceable and important task. As labor costs become increasingly expensive, power is low, and weed recurrence rates are high, weeding cloth can not only save labor by 60% to 80%, reduce costs by 40% to 80%, but also have high weeding power and a more complete weeding effect, etc. Significant advantages, therefore, plant protection technicians in many regions have begun to continuously discuss and promote forestry and nursery physical weed control since the 1980s. Popularizing the physical weeding skills of garden nurseries, adapting to the needs of urban garden construction and the scientific management of nurseries, has gradually become one of the important skills in the management of garden nurseries.
Advantage:
1.It has a variety of physiological and ecological effects such as breathable and hydrophilic, temperature increase, soil protection, no-tillage, fertilizer increase, avoidance and reduction of pests and diseases, and can improve the survival rate of young fruit trees, accelerate growth, help flowering and fruiting, and improve fruit quality. It also has significant economic functions such as saving water, electricity, labor, fertilizer and disease and insect costs.
2, Press the weeds to grow: cover the black weed cloth, because the weeds can not see light after germination, photosynthesis is pressed, it must die, and it works well.
3. Improved ground temperature: After the weeding cloth is covered on the ground, the mulch film can prevent the soil heat from radiating outward, and can improve the ground temperature by 3 ~ 4 ℃.
4. Keep the soil moist: After the weeding cloth is covered on the ground, it can transpiration according to the moisture content of the loquat and adhere to a certain soil humidity, which can reduce the number of sprinkles.
5, maintain soil looseness: after the surface weeding cloth, watering can be ditched between rows, the water penetrates into the root of the canopy laterally, the soil layer under the weeding cloth always adheres to loose, no compaction.
6, improve soil nutrients: early spring weeding cloth cover can improve ground temperature, stabilize soil humidity, create good conditions for soil microbial activities, thereby accelerating the differentiation of soil organic matter, adding soil nutrient content.
7. Avoid and mitigate the damage of pests and diseases: Covering the weed cloth in early spring can prevent the emergence of many pests that overwinter in the soil under the tree, avoid and mitigate the multiplication and infection of the bacteria that damage the fruit trees in the soil, and thus avoid and reduce the occurrence and development of pests . For example, the peach-eating heartworm, grasshopper, etc. all have underground wintering habits. Covering the weed cloth in early spring can prevent such pests from unearthing damage. In addition, the environmental conditions for the growth of the root system are improved, the tree body is strengthened, and the disease resistance of the tree body can be greatly improved.
8.Extended use time
