Polygonum cuspidatum planting, yield per mu, profit, planting technology and economic benefits of Polygonum cuspidatum

The rhizome of Polygonum cuspidatum is very strong and can be used as medicine. Polygonum cuspidatum can be used to treat lung heat cough, and can also be used for injuries, burns, etc. Polygonum cuspidatum also has the effect of promoting blood circulation and dispersing blood stasis. Soaking Polygonum cuspidatum in wine can relieve symptoms such as blood stasis and muscle and bone pain.

How many kilograms can the Japanese knotweed produce per mu?

Under normal planting conditions, the yield per mu of knotweed is about 2000-3000 kg , and the specific yield per mu is related to the planting and management technology. Knotweed is generally harvested in spring and autumn every year. Spring harvesting should be done before the seedlings emerge, and autumn harvesting should be done after the plants wither.

Profit from planting one acre of Japanese knotweed

The economic value of Polygonum cuspidatum is very high. It has the effects of clearing away heat and detoxifying, relieving cough and reducing phlegm, promoting blood circulation and removing blood stasis. The price of Polygonum cuspidatum is about 10-20 yuan per catty , and the profit of planting one acre of Polygonum cuspidatum is more than 8,000 yuan . Polygonum cuspidatum is one of the raw materials of many Chinese patent medicines, and its development prospects in the pharmaceutical market are very considerable.

The planting technology of knotweed

1. Site selection and land preparation

The root system of Japanese knotweed is well developed, and it is cold and drought resistant, and has low requirements for soil. However, it is not suitable for planting in low-lying and waterlogged areas.

After selecting a planting site, first plow the soil 20-25 cm, remove larger stones, break up large clods of soil, and then apply 1500-2000 kg of fully decomposed manure per mu as base fertilizer.

After applying fertilizer, mix it evenly with a 5-10 cm layer of soil, and then make raised ridges. The ridges should be 15-20 cm high and 50-55 cm wide.

2. Breeding method

The general methods of propagation of Polygonum cuspidatum are seeds and rhizomes, but seed propagation takes a long time from sowing to harvesting, and the germination rate of seeds is low and the propagation speed is slow, so rhizomes are mostly used for propagation in production.

3. Field management

After the seedlings emerge from the soil, their growth rate will accelerate as the temperature rises. At this time, weeding should be done well and inter-cultivation should be done in combination with weeding.

When the seedlings grow to a certain size, they must be thinned out and supplemented in time to increase ventilation and light transmission between plants to prevent them from growing too densely, which will affect the growth of the seedlings and easily induce diseases and pests.

Scientific fertilization is the key measure to achieve high yield of Polygonum cuspidatum, so after planting, it is necessary to apply fertilizer in time according to the fertility of the soil. Generally, you can combine tillage and weeding with application of quick-acting fertilizer 1-3 times, and match it with an appropriate amount of trace element fertilizer.

Prospects of Knotweed Planting

The technology of artificial cultivation of Polygonum cuspidatum is mature and the harvest is good. If it is planted using the root division propagation method, Polygonum cuspidatum can be harvested in 2-3 years, with a yield of 2,000-3,000 kilograms per mu.

Based on the current market price of 7-8 yuan per kilogram, the output value of Polygonum cuspidatum per mu is between 14,000 and 24,000 yuan. Excluding the costs of seedlings, fertilizers, pesticides, labor, machinery, etc., the profit per mu of Polygonum cuspidatum planting can reach more than 8,500 yuan, and the economic benefits are still relatively high.

Although the price of artificially cultivated Japanese knotweed is not as high as that of wild ones, the overall market situation is relatively stable and the future prospects are good .
