Key points of cultivation

Ginseng fruit is suitable for field cultivation in south subtropical region or protected cultivation in middle subtropical region. The suitable temperature for the growth of ginseng fruit is 25℃, which can tolerate the low temperature of 3~5℃ and freeze to death below 0℃. It can continue to blossom and bear fruit at 15~30℃, with long lasting fruit-bearing time and high fruit-setting rate, and the yield per mu can reach 2000~3000 kg. Its cultivation points are as follows:

Soil preparation, fertilization and planting: Choose neutral soil with convenient irrigation, ventilation and light transmission, and loose and fertile soil for planting. Ginseng fruit is a perennial herb, with sufficient fertilizer, farmyard manure of 4000-5000 kg and ternary compound fertilizer of nitrogen, phosphorus and potassium of 50-70 kg per mu, row spacing of 40-70 cm and deep ploughing of 20-30 cm. Then the land should be leveled and made into a strip border with a width of 70 cm, and the border surface is 65438+ higher than the ground. Select strong seedlings with height of about 15cm, many branches, thick branches, lush leaves and no pests and diseases, and plant them in the shape of 50cm× 50cm. It is generally advisable to plant it tonight, with 2000~3000 plants per mu. After planting, water your feet.

Fertilizer and water management: in addition to applying base fertilizer, topdressing should be done twice: topdressing should be done once when the fruit seedlings grow to about 30 cm; Another time, when the fruit seedlings were close to flowering, 3 kilograms of nitrogen, phosphorus and potassium fertilizer were applied per mu and poured at a distance of 10 cm from the main roots of the seedlings. Boron fertilizer or trace elements such as Su Baofeng No.2 should be properly applied during flowering and fruiting. A small amount of NPK compound fertilizer should be applied frequently, and attention should be paid to intertillage weeding. Generally, apply fertilizer once every 10 day, and apply more potassium fertilizer after flowering. March-June, September-165438+1October are the periods when ginseng fruit needs the most water for growth, flowering and fruiting, so water it in time.

Pruning: ginseng fruit has strong germination ability, so it should be pruned and raked in time. From the part above 15 ~ 20cm, select 3~5 robust and evenly distributed branches as the main branches, and cut off all the others. Leave 2~3 inflorescences on each side branch, 2~3 fruits on each inflorescence, and all the other inflorescences and small fruits are thinned out. Only 30 fruits can be produced per plant at most. Because the stems of ginseng fruit are soft, it is necessary to build a frame with bamboo poles or plastic ropes at the beginning of mushroom production to prevent lodging.

Pest control: The main diseases of ginseng fruit are late blight and botrytis cinerea, and110 ~150g chlorothalonil is 400~800 times of water, 600~800 times of botrytis cinerea, 1000 times of carbendazim and thiophanate methyl can be used per mu; The main pests are aphids and red spiders, which can be used alternately with 1500 times triclosan, 1500 times pyridazinone and metsulfuron. It should be noted that ginseng fruit is very sensitive to omethoate or dichlorvos and should be banned.

Timely harvesting: when the fruit has clear purple stripes on the appearance, or when the peel is bright and smooth without stripes, it can be harvested. If it needs to be stored, it can be harvested at the seventh and eighth maturity. The storage period is 40-60 days at normal temperature, and it can be listed in the off-season from New Year's Day to Spring Festival.
