Is it okay to plant Panax notoginseng at an altitude of 800 to 990 meters in Wenshan?

Wenshan Panax notoginseng can be planted at an altitude of 800 to 990 meters, depending on whether the growth environment is suitable.

Growing habits:

Aspect: sunny slope of 5-20. ?

Soil quality: well-drained soil, pesticide residues and heavy metals are qualified. ?

Soil microflora: not polluted by the dangerous pathogen of Panax notoginseng. ?

Previous works: non-notoginseng and vegetables. ?

Water and transportation: due consideration.

Distribution range:

Location: Wenshan, Yanshan, Maguan, Xichou, Guangnan, Malipo, Funing, Qiubei, etc.

Tian Yang, Jingxi, Tiandong and Debao are also planted.

Training points:

First, land preparation?

Turn over the ground and dry the ridges before September, and complete 2 plows and 2 harrows 165438+ in mid-June, level and straighten the garden according to the gardening standards, and divide the farming areas. ?

When ploughing the land for the last time, apply decomposed farmyard manure 1 1,000 kg and microbial nitrogen-fixing, phosphorus-dissolving and potassium-dissolving bacteria 1 kg per mu, mix them evenly and sow them, so as to improve soil fertility. ?

Second, gardening?

According to the routine requirements of Sanqi safety production, we will build a high-quality seven-garden with uniform light transmission and flat car surface. ?

Before planting, after gardening, stir it evenly with drugs, then spread it and mix it evenly with the topsoil of 10 cm, and then sow red seeds or planting strips. ?

Third, seedling raising?

Nursery and planting area are arranged according to 1: 6. ?

Seed selection: seed selection in a disease-free seed orchard. After peeling and washing, spread it into a thin layer in the sun and dry it for 2-3 hours. After the water film is dried, air separation is selected and screened with a sieve with a pore size of 5 mm?

Seed disinfection: according to the detection results of the bacteria-carrying situation of seeds and the climatic conditions where the seedbed is located, the main disease types are determined, and the corresponding fungicides and amino oligosaccharides are selected for compound seed soaking treatment. ?

Seed dressing: Before sowing, 20g of microbial soil inoculant is mixed with 100 kg of organic fertilizer per 1 00 kg of red seeds, and then fully mixed with the seeds. ?

Sowing: Sowing at a spacing of 5*4 cm, with about 200,000 pieces per mu. The coverage depth is about 1 cm. The thickness of grass cover is about 1 cm. Water it in time. ?

Prevent pond rot and cultivate healthy seedlings: when the emergence rate reaches 50%, add 75 ml of 2% amino oligosaccharide per mu of leaf synergist, and then spray it once a month in the same way.

Look at the fertilization of seedlings to ensure the balance of three elements. After the seedlings have fully spread their leaves, apply plant ash once every other month, with a dosage of 50 kg per mu. Conventional spraying insists on using pollution-free pesticides. ?

Fourth, transplanting and planting?

The time starts at the end of 1 1 and ends at the end of the following year 1.

Try to choose sunny days to start raising seedlings. Delete diseased seedlings, weak seedlings and non-sprouted seedlings: select high-quality subbands with no diseased spots, good sprouting roots and large size (1000 plant weight 1.65kg or more) and plant them in compartments or gardens.

60 kg per mu (including seedlings).

The rows of plants depend on the level of subbands.

Strive to put it neatly, in the same direction, and the loam is uniform.

Cover the mat grass in time and water it properly. ?

Fifth, topdressing?

We should give priority to farmyard manure and attach importance to the use of microbial fertilizers to maintain the phase balance of soil microbial communities.

Do not use or use less chemical nitrogen fertilizer.

Farmhouse manure that can be used includes manure, compost, drying oil, bone meal, filter mud from sugar factory, leftover from tobacco factory, green manure, plant ash, fireclay, etc. ?

Sixth, adjust the ceiling?

In the growing season of Panax notoginseng, the canopy light transmittance in the middle altitude area was adjusted to 9%- 15%.

Adjust it to 15%-20% at high altitude.

The weather is clear before the rainy season, and the ceiling should be dense: after entering the rainy season, the light transmittance should be appropriately increased. ?

Seven, pest control?

The success or failure of planting Panax notoginseng mainly depends on the prevention and control of pests and diseases in the cultivation process. The green ecological production of Panax notoginseng requires not only controlling the loss of pests and diseases, but also ensuring that the pest control measures do not destroy the ecological environment.

The key measures of pest control include applying resistance inducer to improve the stress resistance of Panax notoginseng plants and weakening the survival and reproduction ability of pests by changing the ecological environment. ?
