Planting technique of Radix scrophulariae

Radix scrophulariae is a commonly used traditional Chinese medicine. The planting technology is simple, and the annual income of planting in the same year. The yield of dry products per mu is about 500kg, the market purchase price is 16 yuan per kilogram, the retail price is 25 yuan per kilogram, and the annual output value is 7000-8000 yuan. Radix Ginseng is not strict with the soil, any soil quality, sporadic border land can be planted. In the past, we used to grow with tuber roots. Here are two planting methods that can reproduce without cost:

First, old root planting

When scraping out, cut off the medicinal tuber root and break off the rest of the old root to be planted, and you can also store it when it is planted along with the planing. When it sprouts in the spring next year, the plant spacing is 0.5 feet, the row spacing is 1.5 to 1.8 feet, and the old root is about 400 jin per mu. The yield of Radix Ginseng planted with old root is lower than that planted with tuber root, but it saves cost. The old root comes from the seed body of root tuber after harvest and seed reproduction.

2. Stem and branch propagation

During the mildew and rainy season, plant 2 to 3 inches of cut or side branches into the ground. The plant spacing is 5 cm and the row spacing is 8 cm. Build a shed to shade, spit beard to take root in 4 to 6 days, pay attention to the soil dry humidity, dry survival rate decreased, wet easy to cause rotten roots, about 10 days to decide whether to survive, a month later can take soil transplanting, harvest before freezing. In April, May and June, regardless of the old root planting or the root tuber planting, the top type should be hit and the lateral branches should be cut off, and the cut branches should be used for propagation, which can save the cost of tuber medicinal materials and rapidly expand the planting area. There are also two conventional planting methods.

1. Root propagation

Apply sufficient bottom fertilizer, turn the land about 1 foot deep, level the bed, thaw in spring and thaw to Qingming Festival are planting time, bud head upward, hole depth 2 to 2.5 inches, covering soil 1 to 1.5 inches, plant row distance is the same as above. The temperature is 18-20 degrees Celsius, the seedlings can be collected in 20 days, and 300 jin of roots are needed per mu.

2. Seed propagation

There is no output value in the first year of seed breeding, so we can only breed the seed body, raise seedlings in a sunny bed or hotbed, apply sufficient bottom fertilizer, water once after forming the bed, sow the seeds on the border surface, cover the fine soil strictly, cover the firewood and grass to maintain moisture, after emergence, remove the firewood and grass, and take the root as the seed body after autumn. After ginseng seedlings come out, weeding is carried out, cake fertilizer or urea can be applied after 1 foot high, seedling height is 2 feet high, flower buds are cut off, pesticides are generally not needed. If there is a red spider, spray it with 2000 times dimethoate.

The harvest time of Radix scrophulariae is that Frosts Descent is relatively free for a period of time before sprouting in the coming year, when he does not compete with other crops for farming, cut off the ground part during harvest, and then dig out the root, put it into medicine, and leave the old root for planting in the second half of the year. After the planed root is half-dry, pile it up for 2 to 3 days, blacken inside and continue to dry until dry.
