Ginseng fruit cultivation techniques:
Site preparation, fertilization and planting : It is convenient to irrigate, ventilated and light, and the soil is loose and fertile in neutral soil. The ginseng fruit is a perennial herb, which should be applied to the base fertilizer, 4000-5000 kg of farmyard manure, 50-70 kg of N, P, K ternary compound fertilizer, 40-70 cm of plant spacing, 20-30 cm deep, and then flattened. The land is 70 cm wide and 10 cm wide. The surface is 10 cm above the ground.
The selection is about 15 cm high, with many branches, thick branches, flourishing leaves, strong seedlings without pests and diseases, planted in 50 cm Ã— 50 cm, generally set to plant tonight, 2000-3000 acres. After planting, water the roots.
Fertilizer management : In addition to applying the base fertilizer, it should also be topdressed twice: once when the fruit seedling grows to about 30 cm; another time when the fruit seedling is close to flowering, apply 3 kg of N, P, and K fertilizer per acre, leaving the root of the seedling. Watering 10 cm away. During the flowering period, appropriate trace elements such as boron fertilizer or Baofengsu No. 2 should be added.
A small amount of N, P, K compound fertilizer, and pay attention to cultivating weeding, generally 10 days to apply a fertilizer, more potassium fertilizer after flowering. March-June and September-November are the periods in which the growth and development of ginseng fruit and the flowering result require the most water, and should be watered in time.
Pruning : The ginseng fruit has strong germination ability. It should be pruned in time. From the 15-20 cm part of the plant, choose 3-5 strong and evenly distributed branches as the main branch, and the rest are cut off. There are 2-3 inflorescences on each side branch, 2-3 fruits per inflorescence, and the rest of the inflorescences and small fruits are all removed. Each plant only has a maximum of 30 fruits. Since the stem of the ginseng fruit is soft, it is necessary to use a bamboo pole or a plastic rope to prevent the lodging from falling.
Pest control : The main diseases of ginseng fruit are Phytophthora and Botrytis cinerea, 110-150 g of chlorothalonil can be used for 400-800 times of water per acre, 600-800 times of solution of gray mold, carbendazim and methyl ketone Bujin 1000 times liquid; the main pests are aphids and red spiders, which can be used alternately with 1500 times of liquid triclosan, 1500 times of liquid pyridazinone and chlorpyrifos. It should be noted that ginseng fruit is very sensitive to omethoate or dichlorvos and should be banned.
Timely harvesting : When the appearance of the fruit appears clear purple stripes, or no streaks, but the appearance of the fruit is bright and smooth, it can be harvested. If it needs to be stored, it can be harvested at the ripening of seven or eight, and stored at room temperature for 40-60 days. The fruit can be listed in the off-season of the fruit before the New Year's Day to the Spring Festival.
