How to interplant traditional Chinese medicine in orchards
In recent years, many fruit growers have interplanting traditional Chinese medicine in orchards, and have gained certain experience. The following is summarized for reference.
1、 Principles of Interplanting Chinese herbal medicines in orchards
Years of planting practice has proved that not all kinds of Chinese medicinal materials can be intercropped in the middle of the orchard, but must be based on the actual situation of the medicinal materials and orchards, according to local conditions, reasonable arrangements, otherwise there will be adverse effects. The main considerations are as follows: first, a reasonable field structure should be formed according to the biological characteristics of different fruit trees and Chinese herbal medicines. For example, the selection of Chinese herbal medicine varieties should be based on shade resistance and shallow root; secondly, the allocation ratio should be properly adhered to the principle of fruit trees as the main and complementary advantages; thirdly, local excellent and authentic herbs should be Interplanted; fourthly, field management should be strengthened to promote mutual benefit and control conflicts to ensure double harvest. If there are fruit growers interplanting chrysanthemum, Anemarrhena asphodeloides and Achyranthes bidentata under the apple trees in the orchard, it is a successful example to scientifically utilize the spatial and environmental advantages of fruit forest and carry out three-dimensional development.
2、 Intercropping pattern between young fruit trees and Chinese medicinal materials
Fruit tree planting After that, the canopy will be formed in 2-3 years. During this period, the reasonable interplanting of Chinese herbal medicine varieties with low stalk, thin plant type and Yang preference can reduce soil nutrient loss, inhibit weed growth and increase income. For example, from the first year to the second year, interplanting Platycodon grandiflorum, Isatis indigotica, dandelion, honeysuckle, Crocus sativus and other smaller plant varieties in the row spacing of 2 meters; in the third year, with the increase of fruit tree crown, a shade environment has been formed in the 2-meter-wide row spacing, which requires the cultivation of Yin loving Chinese herbal medicines, such as Pinellia ternata, bupleurum, Coptis, Arisaema, Rehmannia glutinosa, yam, Anemarrhena asphodeloides, etc. It is worth noting that most Chinese herbal medicines are not resistant to continuous cropping. One is that continuous cropping is prone to disease and yield reduction; the other is that continuous cropping of the same kind of Chinese herbal medicine is prone to lack of certain nutrients. Therefore, it is necessary to change stubble every year or every other year, and choose the suitable crop for its growth.
3、 Interplanting mode of mature fruit trees and traditional Chinese Medicine
After 5 years of fruit tree growth, a shade environment has been formed in the row spacing, and the light transmittance is less than 30%. For example, if Gastrodia elata is planted in autumn or spring, fruit trees provide a cool, humid, oxygen rich and suitable temperature environment for the growth of Gastrodia elata. The suitable varieties of traditional Chinese medicine in mature fruit forest include Coptis chinensis, Panax notoginseng, ginseng, Polyporus umbellatus, Ganoderma lucidum, Crocus sativus, etc.
