Cotton and Pinellia ternata interplanting has many advantages.
After our experiment, in the cotton field interplanting Pinellia ternata, there is no "contradiction" between the two, the yield is not reduced, the per mu income of Pinellia ternata dry medicine 80~100 kg, can increase part of the income. The benefits of interplanting Pinellia ternata in cotton fields are mainly manifested in the following aspects:
1. Use time difference skillfully. According to the characteristics of Pinellia ternata, it grows well in the absence of shade from March to June, and Pinellia ternata must grow in the shade from July to September, when cotton enters the rapid growth stage and its branches flourish, creating a good microclimate for the normal growth of Pinellia ternata.
2. Make full use of light energy. Cotton should grow under conditions of sufficient light and good ventilation. Pinellia ternata likes to grow in a shady environment after July. Cotton absorbs strong light and the "afterglow" scattered to the ground is used by Pinellia ternata. The two do not compete for light and are beneficial to the growth of Pinellia ternata.
3. Fertilizer and water are fully utilized. Pinellia is a shallow root plant, its roots are mostly distributed in the soil surface of about 5 cm, while cotton is a deep root plant, so the contradiction between the two competing for fertilizer and water is very small.
4. Smart combination of height and short, sparse and dense. The multiple cropping index of land has been increased. Cotton tall stalk sparse planting, mu seedling 1000-1500. The pinellia ternata plant height is generally less than 10 cm, mu needs to leave seedlings 180,000 dwarf.
5. Save industry and medicine. Pinellia ternata is not afraid of hoeing harrow, can sprout many times a year, do not avoid pinellia ternata when working in cotton field. Common pests of Pinellia ternata include aphids and red spiders, etc., which can be combined with cotton pest control by spraying 90% trichlorfon 800 times solution to kill them. When treating cotton pests and diseases, it also prevents and controls diseases and insect pests of Pinellia ternata, saving labor and medicine.

Cultivation of Pinellia ternata
1. Growth characteristics: Pinellia ternata prefers warm and humid, half-shaded and half-sunny environment, which is suitable for planting on loose and fertile sandy soil with PH 5.6 ℃ 6.4; Pinellia ternata is afraid of hot and cold, and the suitable temperature for growth is 15 ℃ 25 min, falling seedlings over 26 ℃ and withered seedlings below 13 ℃. Pinellia ternata emerged three times a year, the first from late March to early April, the second in the first and middle of June, and the third in the first and middle of September. The initial stage of bud germination is in early April, and the peak is in the mature period of mid-April.

Technology of intercropping Pinellia ternata in woodland
Pinellia ternata, also known as Pinellia ternata and Pinellia ternata, is a perennial root herb of Araceae. It is used in medicine with tubers and has the function of drying dampness and resolving phlegm, reducing adverse events and stopping vomiting. Resistant to shade, cold and afraid of sunlight, seedlings are afraid of heat, suitable for forest intercropping. 1 Propagation technology Pinellia ternata is generally propagated by underground bulbs and bulbs, as well as seeds. 1.1 when Cold Dew dug the bulb before and after the bulb propagation, the smaller one was selected and buried in a cool and ventilated place with wet soil. before and after the Qingming Festival in the second year, it was transferred into the field according to the row spacing of 10 cm × 6 cm.
