Fruit and vegetable intercropping can improve the orchard's efficiency, but the following relationships must be dealt with: Do not take medicines too close to the fruit trees to prevent them from hurting the trees; do not choose a variety of medicinal herbs with a high degree of lignification. In order to prevent herbs and fruit trees from competing for water and affecting management, it is also necessary to select suitable varieties of medicinal herbs grown locally to prevent climatic conditions from being suitable. We must rely on a flexible information system to select varieties of medicinal materials that have a market demand and a stable price. The varieties of Chinese medicinal herbs planted in fruit trees or in small plots are: Southern Star and Pinellia. Under the condition of direct sunlight, these two herbs will have a phenomenon of suspended animation when the temperature reaches 32°C. When the temperature drops to 28°C, they will re-grow. Therefore, it is more appropriate to make full use of the spacing of the fruit trees and interplanting Nanxing and Pinellia. The planting method is as follows: Southern Star is planted in late March with a spacing of 20 cm X 20 cm. Before sowing, it is necessary to make a fine soil preparation, apply sufficient basal fertilizer, soak the bulbs with 50% carbendazim 800 times for 12 hours, then dry them and cut them. During the growing season, weeds are cultivated. The harvest period in the beginning of winter - light snow. Pinellia sowing in late March, line spacing 10 cm X10 cm, sowing bulbs, buds horizontally, Pinellia buds up to 2.5 times the bulbs when the birth of new bulbs. During the birth period, the soil should be covered three times, and water should be poured in early June. The temperature should be reduced by 10 cm thick. When the temperature drops, sprouts will be added. Harvest before and after the white dew.
