1, ginseng fruit prefers temperature to high temperature, and can grow and develop normally in the range of 10~35℃. The optimum temperature for growth is 20~25℃ during the day, 8~ 15℃ at night, the optimum temperature for fruit setting is about 20℃, and the plants die below 0℃. The suitable ground temperature for root growth is 20℃. If the ground temperature is lower than 10℃, the growth of root hairs will slow down or stop. Ginseng fruit likes sunshine for a long time, especially when it is ripe. If there is not enough sunshine, it will delay maturity. If the light is too strong, accompanied by high temperature and dryness, it is easy to cause the leaves of plants to roll, and the disease is aggravated.
Ginseng fruit has strong adaptability to soil. Planting in loose, fertile and slightly acidic soil has good growth, high yield and good quality. Therefore, it is advisable to choose a field close to the suburbs or with convenient transportation, abundant water, no pollution source, high terrain, flat land, ventilation and light transmission, convenient irrigation and drainage, high organic matter content, deep soil layer, loose and fertile soil, slightly acidic and suitable pH value of 6~7. Avoid planting ginseng fruit in saline-alkali and strongly acidic soil. If it is unavoidable, lime or sulfur powder should be used to adjust its pH value. It should also be noted that it is not suitable to interplant with other crops such as pepper, eggplant, tomato, potato and tobacco. So as to avoid soil-borne diseases and reduce the yield.
