Banlangen is a commonly used traditional Chinese medicine in China, which is cultivated in many places, and has the functions of clearing heat and detoxification, cooling the blood and improving the pharynx. Based on this, to share with you the planting management points of Panax quinquefolium, I hope it can help those who are engaged in the planting of Panax quinquefolium.
One, the land selection
Blue root is a deep-rooted plants, the length of its main root can reach 40 to 50 centimeters, so the requirement of the underground water table to be low, well-drained, and is loose fertile sandy soil or river alluvial soil for planting, if it is too sandy, too viscous, especially low-lying areas. Its growth and development are not very good, and it is easy to fork. It is a kind of plant that likes big fertilizer and tolerates fertilizer, it is recommended to apply 60,000 kg of rotted stable fertilizer, 750 kg of calcium superphosphate, 450 kg of potassium sulfate, and 300 kg of urea per hectare to make the bottom fertilizer. (1 hectare = 15 mu) to deep turning 30 cm, at the same time to make fine raking to break up the soil, and then made into beds, it is recommended that the northern region into flat beds, the southern region into raised beds, so that is conducive to drainage, beds 1.5 ~ 1.8 meters wide, beds 20 ~ 30 cm high, but also have to work the channel 30 centimeters, pay attention to all around the drainage ditch to do a good job.
Two, seed treatment and sowing method
①Panax quinquefolium is not flowering and fruiting in the first year, in the year of harvesting the root to choose no pests and diseases, thick and strong, do not forked roots to storage, in the spring of the second year in accordance with the row spacing is 50 cm, plant spacing is 20 cm to planting, and in time for the watering, loosening the soil. Watering, loosening the soil, in the flowering of the shoots and then apply a fertilizer, in May when the seeds are ripe, collect and dry to save for the next year's seed.
Before sowing, soak the seeds in warm water at 40℃ for 4 hours, fish them out and then mix them with grass ash.
②Time and method of sowing
Spring and summer sowing can be used, in the northern region or spring sowing is better, spring sowing time is in March to April, summer sowing is in May to June. Selected ridge sowing requires the use of a wide seedling strip sowing, ridge width is recommended to be 60 centimeters, plant spacing is 3 to 4 centimeters, stay into a double row of inflection seedling. In the case of border sowing, the spacing between rows is 20 centimeters, and the recommended seedling holding capacity is 6 to 7.5 million plants per hectare. At the time of sowing digging a 2 cm deep furrow, and then spread the seeds in the furrow, the thickness of mulch is 0.6 ~ 1 cm, to be stepped on a foot, or choose the roller gently pressed again, when the soil moisture reaches the field's maximum holding capacity of 65% ~ 70%, 4 ~ 10 days after sowing the seedling can be out of the seedling. The amount of seed used per hectare is 22.5-30 kilograms.
Three, field management
1, plowing weed, between seedlings, set seedling
After sowing, pay attention to the observation, when the cover of the film has 70% of the emergence of the seedling can be uncovered and shallow hoeing, pay attention to remove the small weeds. When the seedlings of the bluebells have a height of 3 to 5 centimeters, the seedlings and weak seedlings are removed, leaving the strong seedlings, the recommended seedling spacing is 4 to 6 centimeters. The recommended spacing is 4 to 6 centimeters. When the seedlings are 7 to 10 centimeters tall, start to set the seedlings, the recommended spacing is 8 to 10 centimeters. Be careful not to leave seedlings too dense, seedling spacing is too dense when the root is small, the leaves are not fat, when the seedling spacing is too large when the main root is easy to fork, and is more fibrous roots, the strip is not straight, of course, the yield will not be too high.
2, fertilizer, irrigation
After the seedling is set according to the growth condition of the root, you can apply a manure or choose inorganic fertilizer, every harvest of the big green leaves must pay attention to reapplication of manure, which can promote the growth of the root and increase the yield. You can spray foliar fertilizer, preferably choose 0.2% potassium dihydrogen phosphate, sprayed 2 to 3 times in the middle and late growth. Also note that, in the dry weather, pay attention to watering, in order to facilitate the normal growth of the roots, choose to carry out in the morning and evening of every day, not in the sunshine, to the rainy season in time to remove the stagnant water, if the long-term stagnation of water, the roots of the roots of the roots will be easy to rot and cause a reduction in yield.
Blue root can be harvested from the leaves, but also from the roots, need to pay attention to the choice of time. The leaves can be harvested two to three times a year, and it is important to note that the high temperature of the season is not allowed to harvest, so as to avoid the occurrence of disease and death of the plant. The harvesting of the blue root is in October to December after the first frost, when the local parts are withered, you can dig, choose to carry out in continuous sunny days. Don't dig it off to avoid reducing the quality of the root.
