Is Hezhou, Guangxi suitable for planting ginseng fruit?
Ginseng fruit is suitable for field planting in south subtropical region and northwest region, or protected cultivation in middle subtropical region and greenhouse planting in north 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 blossom and bear fruit continuously at 15-30℃, with long continuous fruiting time and high fruit setting rate, and the yield per mu can reach 2000-3000 kg. Its cultivation points are as follows:
Fertilizer and water management
In addition to applying base fertilizer, topdressing should be done twice: topdressing once when the 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.
prune
Ginseng fruit has strong germination ability, so it is necessary to trim the bifurcation in time. From the part above 0/5-20 cm of the plant/kloc-3-5 robust and evenly distributed branches are selected as the main branches, and the rest are cut off. Leave 2-3 inflorescences on each side branch, 2-3 fruits on each inflorescence, and all 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.
control of insect
The main diseases of ginseng fruit are late blight and gray mold, and chlorothalonil 1 10- 150g, gray mold 600-800 times, carbendazim 1000 times 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 harvest
When the fruit has clear purple stripes on its appearance, or when the fruit has no stripes but the skin is bright and smooth, 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 room temperature, and it can be listed in the off-season from New Year's Day to Spring Festival.
