Water spinach, also known as Ipomoea aquatica, water spinach, rattan vegetable, etc., is an annual herb of the family Ipomoea batatas. It is commonly cultivated in central and southern provinces of our country. It can be used medicinally except for vegetables, and it can be used internally to solve dietary poisoning. External application to treat fractures, ascites and nameless swelling poison is also a better feed. Let's take a look at the seed price and planting method of spinach.

How much is the asparagus seed?

The price of asparagus seeds is about 20 to 30 yuan per jin, but the price varies greatly among varieties, producing areas and quality. Rabdosia angustifolia is a kind of amphibious plant which can live in both dry land and paddy field, but it still grows vigorously when there is more water, so it is most suitable to be planted in the fields with frequent defecation water near the fertilizer paddy field or livestock house, and can also be planted in the fatter dry land. and planting in dry land can promote it to bear more seeds, so it can be cultivated in dry land when keeping seeds.

Cultivated varieties of asparagus

1. Thai hollow cabbage: Thai hollow cabbage is heat-resistant and waterlogging-resistant, with exuberant growth at high temperature and humidity in summer, not cold-resistant, and suitable for high-density cultivation. Cultivated in the open field in Yichun and summer in the north, twigs can be harvested for 2-3 months, with crisp texture, strong taste and good quality. yield 3000 kg per mu.

2. White stem: the stem of white stem is thick, yellow and white, with strong growth, few branches, good quality, high yield, fertilizer tolerance, suitable for sewage fertilizer paddy field cultivation, dry land cultivation should be watered frequently, sowing to the beginning of harvest for 60 to 70 days, and the yield per mu is 5000 kg.

3. Ji'an water spinach: Ji'an water spinach is a local variety in Jiangxi, with semi-erect plant, luxuriant stems and leaves, long growth period, 50 days from sowing to the beginning of harvest, 70 days of harvest and a yield of 3000kg to 3500kg per mu.

4. Green stem water spinach: green stem water spinach is a local variety in Hunan Province. The plant is semi-erect and precocious. It can be harvested 50 days after sowing. The growth period is 210 days, and the yield is 2500-3000 kg per mu.

5. Fine-leaf water spinach: the plant of fine-leaf water spinach is short, strong stress resistance, cold resistance, heat resistance, wind and rain resistance, crisp, strong taste, good quality, but the yield is slightly lower, from sowing to the beginning of harvest for 60-70 days, the continuous harvest can reach more than 180 days, and the yield per mu is about 2500 kg.

Sowing method of asparagus

1. Nursery bed preparation: 20 kg of sifted farm manure and 50 g of phosphoric acid are applied to the seedling bed of hollow cabbage per square meter, turn it over shallowly, hold it flat, and pour enough bottom water.

2. Sowing time: the sowing time of early spring in solar greenhouse in North China is mid-February, direct sowing in open field in late March, sowing in autumn greenhouse from late May to early June, and sowing in high-efficiency and energy-saving solar greenhouse is generally in the first and middle of September.

3. Seed soaking and sprouting: soak the seeds in about 30 ℃ warm water for 12 hours, remove and drain the excess water, mix the seeds with 35% metalaxyl wettable powder, accelerate germination in 30 ℃ environment, Amoy the seeds with 25: 30 ℃ warm water once a day, sprout in 2 days and sprout in 3 days.

4. Sowing method: 3-5 seeds per hole and 2.5-3.0 kg per mu during direct seeding. Seedling bed sowing and seedling thinning method is adopted in seedling transplanting. After sowing, the seed is covered with 1 cm of soil, the seedling bed area is 50,60 square meters per mu of planting field, and the seed amount is about 2.0 kg.

5. Post-sowing management: strengthen fertilizer and water management when asparagus seedlings are 3 cm high, avoid drought. Seedlings with 2 leaves and 1 heart, the distance between seedlings is about 6 cm. During the growth period, 20 mg / L gibberellin solution can be sprayed once every 10 days, twice in a row. Seedlings with 4 leaves and 5 leaves were transplanted into the field.

Planting method of asparagus

1. Fertilization and soil preparation: asparagus has strong adaptability to soil, not only fertilizer tolerance, but also waterlogging tolerance, but also has a certain resistance to barren, per mu of mature organic fertilizer about 3 tons, diammonium phosphate 50 kg, ploughing and raking fine to make beds, the width of the border is 1.0-1.2 meters.

2. Planting method: about 30 days after sowing, the seedling height was 17 cm and 20 cm according to the row spacing of 30x35 cm, with 3 plants per hole, or 2 plants per hole according to the row spacing of 18x35 cm. The seedlings should be irrigated first and then planted with soil to slow down the seedlings.

3. Fertilizer and water management: after planting, it is necessary to strengthen fertilizer and water management, apply about 10 kg of available nitrogen fertilizer per mu, the amount of topdressing should not be large, and keep the soil moist during plant growth. Topdressing fertilizer is required for each harvest, and the standard is 10-15 kg of urea per mu.

4. Intermediate ploughing and weeding: in order to prevent border hardening and weeds and affect the growth of plants, puccinellia oleifera can be used to promote the development of roots and create a favorable environment for the robust growth of plants.

5. Temperature management: the planting of asparagus should keep the temperature as high as possible, the temperature should not exceed 35 ℃, and the lowest temperature at night should be kept above 15 ℃. In order to promote the growth of asparagus during the period of low temperature, a small arch shed can be added to increase the temperature in the solar greenhouse.

6. pest control: the main diseases and insect pests of asparagus are white rust, wheel spot, aphids, Plutella xylostella and curly worms, etc., which should be strictly "prevention-oriented" in production, and pesticide application should be prohibited during harvest.

7. Timely harvest: when the plant is more than 30 cm, leave the lower part 9 cm 12 cm to harvest the upper shoot, and start the second harvest when the new shoot growing from the axil of the leaf is 15 cm long, but 2 leaves should be left in the lower part. Only 1 leaf is left under each new shoot after the third harvest.
