Can the latest planting of heavy buildings make money?

Zhonglou, also known as Dianzhonglou, single-legged lotus, Huazhong Lou, etc., is a perennial herb of the Liliaceae. The rhizome is used in medicine to clear away heat and detoxify, relieve swelling and pain, cool the liver and calm down. It is mainly produced in Yunnan, Guizhou, Sichuan and other provinces. Now it has been cultivated all over the country and has high medicinal value and planting prospects. Let's take a look at whether we can make money by planting Zhonglou.

Can you make money by planting heavy buildings?

The growth cycle of heavy buildings is long, and wild resources are basically on the verge of breaking down. at present, inventory is very weak in the market. at the same time, the cost of planting heavy buildings is high, it takes a long time and can not quench their thirst, coupled with the delisting of fake and inferior goods. therefore, the fundamentals of the contradiction between supply and demand can not be changed in the next few years and will only intensify day by day, so the prices of heavy buildings will continue to operate at high levels in the next few years. From these aspects, the development of heavy building planting is very promising, but measures must be taken in accordance with local conditions, and we must not blindly follow the trend.

The breeding method of Rhizoma Polygoni

1. Rhizome propagation: in autumn and winter, the rhizome is harvested and stored in a cool and dry place without diseases and insect pests. It is taken out in the first and middle April of the following year, cut into small segments according to the characteristics of bud remnants and bud marks, and each section is guaranteed to have a bud mark. After cutting, the grass ash is properly dried and cut in the seedling bed like sowing, and covered with film. After 11 days, the roots are cut off and the roots take root and take root. In early May, it was transplanted to Daejeon according to the live broadcast specification.

2. Seed propagation: direct seeding can be used for seed propagation, but seed seedling and transplanting can also be used for seed saving and high yield.

① seed direct seeding: after soaking rain in the first and middle of January, hit a small shallow pond with a row spacing of 30cm 35cm, a plant spacing of 20cm, a depth of 3cm, a narrow soil moisture of 130cm and a wide soil moisture of 150cm. Sow the seeds coldly for 24 hours before sowing, sow with plant ash, sow 2-3 seeds in each pond, and cover 2-3 cm of fertile soil with half of fine soil. The dry soil should be watered in time and germinate in 7-10 days.

② seedling transplanting: select the seedbed in the dry land or vegetable garden with water pool in early April, disinfect the soil with pentoxynitrobenzene before digging the soil, then flatten the soil moisture surface, open a sowing ditch about 5 cm deep in the soil moisture surface, plant in the ditch according to the plant spacing of 5 cm, then cover the soil with 3 cm, cover fine dung 2 cm, water thoroughly and cover the plastic film, the seedlings can emerge in 1 or 7 days, and the seedlings can be raised in January. Transplant the seedlings to the field according to the live broadcast specifications.

The planting method of heavy buildings

1. Soil selection: heavy buildings do not have strict requirements on climate and soil types, but it is most ideal to choose shaded slow graveyards or flat land with relatively short shade in Rixi, and the night tide land, ash bubble soil and rotten land with loose texture, strong water retention and water retention.

2. Soil preparation and fertilization: the root system of the heavy building is not deep. After general soil preparation, the soil moisture is 120-150 cm wide, and the soil miscellaneous fertilizer or forest humic fertilizer is applied to 3000-5000 kg per mu, and then the ditch is covered with fertilizer and shallow hoe once, so that the fertile soil in the tillage layer is uniform, leveled and fine to be planted.

3. Seedling replenishment: the seedlings were planted in the middle and late May, and the seedlings were filled in the pond at the same time. The seedlings should be watered before the seedlings were watered, and the seedlings should be watered with wooden pry and fixed root water when replenishing the seedlings, so as to make full use of the seedlings to ensure the whole seedling and sufficient density.

4. Intermediate ploughing and weeding: the growth of the aboveground part of the heavy building is weak, and special attention should be paid to loosening the soil and weeding. Generally from late May to early June, there are many torrential rains and the soil is easy to harden, so it is necessary to drain and prevent waterlogging in time, plough the soil frequently, loosen the soil shallowly, and pay attention to the removal of weeds at any time.

5. Timely shading: heavy buildings like shading and fear strong light, and the whole growth period should be 40-50%. Therefore, shading measures should be taken after emergence and transplanting, and shading nets should be used in places where there are conditions, and shading methods can be adopted in places where there are no conditions.

6. Topdressing and cultivating soil: the heavy building has the growth law of flowering above and expanding the tuber below. Generally, it grows fastest from mid-June and late June to August, and topdressing must be applied again in the first ten days of June. 2000kg / mu cattle and sheep stable manure or 20kg / mu manure plus calcium 2030kg.

7. Timely harvest: the heavy building can be harvested before and after falling seedlings in autumn, that is, from November to December to the spring of the following year, and most of the tubers grow in the topsoil layer, which is easy to dig, but we should pay attention to keep the tubers intact, wash them after digging out, open slices fresh and dry them in the sun.
