The cultivation of Nansha cucumber, the planting method and time of sand cucumber?

1.Introduction to Nansha ginseng

Nansha ginseng is also called sand ginseng, slightly cold, sweet in nature, with the effect of clearing heat and detoxifying, nourishing yin, and relieving cough. Now it is planted in Yunnan, Guangdong, Jiangxi, Hebei, Northeast China, Jiangxi, Guizhou, Anhui, Jiangsu, Zhejiang and other places. So when is the best month to sow Nansha ginseng seeds?

What are the planting techniques? Let's take a closer look at these issues.

2.Nansha ginseng planting method

First of all, it is necessary to select a fertile, sunny and well-drained plot, mix 2,000 to 2,500 grams of circle fertilizer with 2,000 yuan of phosphorus fertilizer per mu, turn it 30 centimeters deep, and make a 1 meter to 1 meter 3 furrow after leveling. Secondly, it is mainly propagated by seeds, which is divided into two periods: autumn sowing and spring sowing. If it is sowing in autumn, it is necessary to choose before the freezing in November, if it is sowing in spring, it is best to choose the first and middle of April, according to the row spacing of 30 to 40 cm, open a shallow ditch of 4 to 6 cm, sow the seeds evenly, cover it with broken soil, compact, water, cover the grass, promote germination and moisturizing, and keep warm.

3.When is the best month to sow Nansha ginseng seeds? What are the planting techniques?

In general, seedlings can grow twenty days after sowing in spring, sowing seeds in autumn, and seedlings will grow in the spring of the following year. When the seedlings grow to three true leaves, they should be thinned in time. When the height of the mu grows to 12 to 15 cm, it is necessary to set the seedlings with a plant spacing of 10 to 15 cm, proper watering, and top dressing.

After the regular period, it is necessary to regularly weed, loosen the soil, top dressing, provide sufficient nutrients for it, avoid soil compaction, and when it rains, it is necessary to discharge the stagnant water in time, otherwise it will cause pests and diseases.

It can be done in the spring months, or in the summer months, or before the winter freezes. Soak the seeds in water for 5-10 minutes, dry them overnight, sow them in the soil and cover them with soil.

Beisha ginseng can be sown in autumn or spring. Autumn sowing is carried out before the autumn freezing, and the seeds can be treated with wet storage, or dry seeds can be used for direct seeding; Spring sowing takes place after thawing in early spring, and the seeds must be frozen in winter. The method of seed treatment is as follows:

The newly harvested seeds of the year are mixed evenly in the ratio of 1 part of seeds and 3 parts of clean fine river sand before winter, packed into wooden boxes and buried in the ground at a depth of 15 to 30 cm for wintering, and taken out for sowing after thawing in the next spring. Choose deep soil, loose and fertile soil, sunny, well-drained sandy loam or silt land, windy sandy land, sprinkle 4000 5000 kg of fine soil miscellaneous fertilizer every 667 meters, add 25 50 kg of soybean cake is better, and also add a certain amount of phosphate fertilizer, diammonium phosphate or compound fertilizer. Turn it deeper than 50 cm, and neat and fine.

The sowing row spacing is 25 cm, the sowing depth is 4 to 5 cm, and the soil is covered immediately after sowing and suppressed.

.Planting time Sand cucumber can be sown in autumn or spring. Autumn sowing time is 9 October, which is carried out before the autumn freeze, and the seeds can be stored wet.

2.Seed treatment The newly harvested seeds of the year are mixed evenly in the ratio of 1 part of seeds and 3 parts of clean fine river sand before winter, and they are packed into wooden boxes and buried.

3.Land preparation and fertilization Choose * deep layer, * loose and fertile, sunny, well-drained sandy loam or silt land, wind-blown sandy land, every 667 meters.

4.Field management S. japonicus seedlings 2 3 true leaf time seedlings, with the seedling leaves not overlapping as the degree, the seedling height is 12 15cm.

The seeds of S. japonica have the characteristics of post-embryonic ripening and dormancy, which can germinate smoothly after low temperature treatment of 0 5 under wet conditions, and the germination rate increases with the extension of low temperature treatment time. Beisha ginseng can be sown in autumn or spring. Autumn sowing is carried out before the autumn freezing, and the seeds can be treated with wet storage, or dry seeds can be used for direct seeding; Spring sowing takes place after thawing in early spring.

Sand cucumber is a perennial herbaceous plant that can grow up to about 40-80 cm. It has carrot-shaped roots, unbranched stems, and some soft hairs on it, some hairless. Its blades are oval, narrowly ovate, and the base part is wedge-shaped or rounded and obtuse.

The tips of the leaves are slightly sharpened, and the edges of the leaves are slightly serrated.

Usually it is cultivated by seeds, but it can be done in April in the spring and before freezing in the winter. Prepare the garden for cultivation, place its seeds in a furrow and cover it with a layer of soil with a thickness of centimeters, press it slightly, and pour the soil with water to moisten it.

After it has grown seedlings, it needs to be weeded and the soil loosened properly. When the seedlings grow to a height of 3 cm, the seedlings need to be thinned, in the process of its growth, it is necessary to apply fertilizer appropriately, which can promote the growth of seedlings more robustly, usually using human and animal manure as fertilizer, but attention should be paid to thin fertilizer and frequent application.

1. Sand cucumber is mostly distributed between 400 and 800 meters above the sea regardless of domestic species or wild, and likes to be born in warmer areas, slightly cold-tolerant, but not high-temperature resistant;

2. In case of high temperature and humidity, it is easy to get sick, especially in the seedling stage, and it is more afraid of strong sunlight;

3. The average annual temperature of Sha Shen is about 16 degrees Celsius, the annual rainfall is about 900 mm, the average relative humidity is about 97 percent, the annual daily skin extinguishing stove shines for 1200 hours, and the frost-free period is about 330 days;

4. The soil is required to be deep, loose, fertile, well-drained oil sand soil or yellow clay with sand is the most suitable;

5. In the heavy clay mud or yellow mud soil, not only the growth is poor, but also inconvenient harvesting;

6. Heavy sandy soil that is too vegetable pine is not suitable for cultivation;

7. The requirements for sand cucumber are not strict before the sale, but avoid continuous cropping, if continuous cropping, pests and diseases are more serious.
