In organic agriculture, weeding is an important task as weeds compete with crops for nutrients, water, and sunlight, thereby affecting crop growth and yield. However, unlike traditional agriculture, organic agriculture cannot use chemical herbicides. So how does organic agriculture weed? Below are several commonly used weed control methods in organic agriculture.
1、Manual weeding
Manual weeding is the most traditional method of weeding and one of the most commonly used methods in organic agriculture. Although this method is time-consuming and laborious, it can effectively control the growth of weeds and avoid the harm caused to the environment and human health by the use of chemical herbicides. When manually weeding, tools such as hoes and shovels can be used to uproot the weeds or manually remove them. It should be noted that when weeding, efforts should be made to avoid damaging the roots of crops.
2、Covering and weeding
Covering and weeding is a method of inhibiting weed growth through the use of coverings. This method can effectively prevent weed seeds from sprouting and growing, while also maintaining soil moisture and temperature stability, which is beneficial for crop growth. Common coverings include plastic film, straw, sawdust, hay, etc.
Traditional ground cloth, however, is prone to weathering and difficult to recycle due to its close contact with soil, which is not breathable and has poor insulation and water retention properties. Its application cost is too high and the covering effect is average.
Farmer’s first grade grass proof cloth – more breathable and permeable
But with the rapid development of agriculture in our country, more and more people are also starting to use grass proof cloth. Grass proof cloth is a safe, long-lasting, economical, and convenient ground laying material that blocks sunlight and prevents weeds from growing. It has a good grass proof effect and eliminates the high cost and trouble of manual weeding.
Watering can be done directly. The surface of Farmer’s First Grade Grass Protection Cloth contains a large number of permeable and breathable holes, and the special bubble pattern design makes the water more evenly permeable.
Good breathability, not stuffy, the roots of fruit trees can breathe naturally, and the soil will not harden. Although traditional plastic woven fabrics are moisturizing, their breathability is indeed low, which can cause certain damage to the soil and fruit trees.
3、 Mechanical weeding
Mechanical weeding is a method of removing weeds through mechanical equipment. This method is suitable for large areas of farmland and can effectively improve weed control efficiency. The commonly used mechanical equipment includes weeding machines and rotary tillers. When using mechanical equipment, pay attention to adjusting the height and depth of the equipment to avoid damaging the roots of crops.
4、 Biological weed control
Biological weed control is a method of using organisms to control weed growth. This method can effectively reduce the number of weeds, while also increasing soil fertility and improving soil structure. Common biological weed control methods include releasing poultry, planting green manure, and utilizing natural enemies. When using biological weed control methods, attention should be paid to selecting appropriate species and quantities of organisms, and planting strong and weak or reasonably dense plants to ensure weed control effectiveness.
There are many weed control methods in organic agriculture, each with its own advantages and disadvantages. When selecting weed control methods, it is important to choose the appropriate method based on the actual situation to ensure weed control effectiveness and crop growth. At the same time, attention should be paid to protecting the environment and human health, and avoiding the harm caused by the use of chemical herbicides to the environment and human health.
