Where does the snow lotus grow?

Saussurea fruit is a kind of fruit with enough water, which can not only be peeled and eaten directly, but also can be used for cooking, and its nutritional value is high. So, where does the snow lotus grow?

First, where does the snow lotus grow?

Saussurea fruit is native to the central plateau of the Andes in South America from north-central Chile to Peru, Ecuador and Bolivia. New Zealand, Japan, Brazil, South Korea, Europe and other places have been introduced and cultivated. It has also been introduced and cultivated in Yunnan, Fujian, Guizhou, Sichuan, Hunan, Hubei, Shaanxi, Henan, Shandong, Hebei, Taiwan, Hainan, Beijing, Tianjin, Liaoning and Dalian.

2. planting techniques of Saussurea involucrata

1. Land preparation

Select neutral or slightly acidic sandy soil blocks with convenient drainage and irrigation, fertile soil, deep soil layer (more than 50 cm) and organic matter content of more than 15%. During soil preparation, fine, uniform and loose soil conditions are required to create deep and loose soil conditions to improve soil permeability, water storage, fertilizer conservation and drought resistance, which is conducive to the full growth and development of roots and root expansion. In the year before planting, turn about 30 cm deep in winter, sunburn, open deep trenches to make beds, make wide beds in plots with good drainage, and make narrow or high beds in plots with poor drainage (the beds are 35-40 cm high, 100 cm wide and 40 cm wide).

two。 Colonization

The single row planting method is adopted, the row spacing is about 140 cm, the plant spacing is about 50 cm, and the planting density is 900-950 plants / mu. When applying base fertilizer, open a ditch about 20 cm deep in the middle of the border, spread a layer of quicklime evenly in the ditch, and then concentrate on the application of base fertilizer. Base fertilizer 1 kg of commercial organic fertilizer and 0.5 kg of plant ash are used for each hole. After applying a layer of thin soil on the surface of the base fertilizer, transplant the seedlings and pour through the fixed root water.

3. Nurture

Fertilizer and water management: snow lotus fruit needs less water in the early stage of growth, but in the middle and later stage of growth, with the expansion of root tuber, the water demand increases sharply, so it should be irrigated in time. Fertilization is mainly based on base fertilizer and proper topdressing of potash fertilizer. In the tuber root expansion, combined with ploughing and soil cultivation, each plant is applied 50 grams of potassium sulfate, timely ploughing and weeding, and pay attention to soil ridging, do not expose the inflated roots outside the soil surface.

Pruning and coring: when the stem of Saussurea involucrata grows to 1 meter high, there will be some tillering branches, and too many branches should be removed; overgrown plants also need to be coring to control the growth of the aboveground parts and promote the expansion of tuber roots.

4. Harvest

There is no legal ripening standard and harvest time for Saussurea fruit, but in production, the time of harvest is closely related to its yield, storage, seed retention, processing and utilization and rotation. Due to the crisp and tender root juice, early harvest is easy to crack, reduce the quality and increase the rate of split potato, it is appropriate to dig in succession after the soil is slightly dry and the root loses water naturally in early December, which can reduce the rate of split potato; too late harvest is easy to suffer cold damage.

5. Leave a seed

After the snow lotus fruit is dug, cut off the bulb bud, wait for the wound to dry, smear it with 75% potassium permanganate solution, or soak it with 10000 times potassium permanganate solution for 3 minutes, fish it out, bury it in the cellar with wet river sand or indoor fake planting without frost damage, with bud eyes facing up, when the river sand is removed from February to March of the next year, and when the seed bud is about 4 cm long, it can be planted (all places should be determined according to temperature).

Saussurea fruit not only has high nutritional content, but also has medical value, and the yield is also good, which is very suitable for farmers.
