1. Principles to be followed when interplanting Chinese herbal medicines in orchards: First, according to the biological characteristics of different fruit trees and Chinese herbal medicines, a reasonable field structure should be formed. The selection of Chinese herbal medicine varieties should be based on resistance to negative and shallow roots; secondly, the allocation ratio should be appropriate, adhere to the principles of fruit trees as the main principle, and complement each other; thirdly, local specialties and real estate herbs should be interplanted; Field management, mutual promotion and mutual benefit, control of contradictions to ensure double harvest.
2. The intercropping pattern between young fruit trees and Chinese herbal medicines: After the fruit trees are planted, they usually form crowns 2 to 3 years before they have a certain degree of shade. During this period, reasonably interplanting varieties of Chinese herbal medicines with low stems, thin plant types, and relatively hi Yang can achieve the purpose of reducing soil nutrient loss, inhibiting weed growth, and increasing yield. For the first year to the second year, a small variety of plants such as bellflower, indigo root, dandelion, honeysuckle, and saffron are planted in a 2-meter-wide row; in the third year, as the crown of the fruit tree is increased, it is 2 meters. The more shaded environment that has been formed in the wide row spacing, it is necessary to grow Xiyin herbal medicines, such as dry Pinellia, Bupleurum, Coptis, Arisaema, Rehmannia, Chinese yam, Anemarrhena and so on. It is worth noting that most Chinese herbal medicines are not resistant to continuous cropping. Therefore, they should be changed every year or every other year, and they should be chosen for their suitable growth.
3, mature fruit trees and Chinese herbal medicine Intercropping pattern: 5 years after the growth of fruit trees, spacing has formed a more shady environment, the transmittance of less than 30%, to choose the right variety of intercropping. For example, in the fall or spring planting of Tianma, fruit trees provide a cool, oxygen-rich, and temperature-friendly environment for gastrodia growth. Mature Chinese medicinal materials suitable for interplanting in mature fruit trees include Coptis, Panax notoginseng, Ginseng, Polyporus umbellatus, Ganoderma lucidum, and Safflower. Http://
