Description

Technical field:

[0002] In order to increase the yield and appearance of vegetables, vegetable farmers often use chemical agents and fertilizers. Long-term use of chemical agents and fertilizers will destroy soil structure, reduce soil fertility, increase the residual harmful substances, and cause harm to human health. With the improvement of public health awareness and environmental awareness, people's demand for vegetables that are free of chemical pollution and sustainable production is growing. Vegetable interseeding refers to the process of vegetable production, through the reasonable planning of planting spacing to achieve mutual symbiosis between crops, reduce the use of chemical fertilizers and pesticides, so as to achieve the purpose of improving soil fertility and optimizing the crop growth environment. For example, the special fragrance secreted by aromatic vegetables and some onion and garlic vegetables can repel pests, and onion and garlic vegetables can also secrete some sulfides, which can not only inhibit soil damage, but also provide rich organic matter for the soil to achieve biological control. In addition, vegetable interseeding can also improve soil structure and water retention capacity, improve soil resistance, reduce soil erosion, promote the activity of beneficial microorganisms, reduce fertilizer application and management costs, and increase yields.
