Water dropwort seed planting method and timing, with dryland cultivation techniques

SummarySeedbed: Water dropwort prefers cool shade and needs relatively loose, thick, fertile soil that drains and irrigates easily. Soil preparation: generally about 1 m wide, apply 2 kg of manure fertilizer per mu. Germination: soak the seeds for about 2 days. Sowing: sow in early August to early September for autumn, and in late September to late October for winter. Management: in dry weather, water once in the morning and once in the evening; start topdressing once the seedlings are uniform, and also pay attention to pest control at ordinary times.

Recently the price of water dropwort has not been very low, but because there are many large growers, everyone does not need to worry too much; even if the price is very high, you can choose to grow water dropwort yourself, because the cultivation method of water dropwort is similar to that of ordinary vegetables, only its water requirements are a bit more demanding. So how exactly do you grow water dropwort? Let us take a look together.

Water dropwort seed planting method and timing

1. Water dropwort seed planting method

1. Sowing and raising seedlings: The seed coat of water dropwort is relatively thick, which makes it not easy to germinate, so seedling raising and transplanting are generally used. When sowing in spring, is low-temperature treatment needed? If you choose to sow in autumn, then low-temperature treatment is needed. Generally, before sowing, soak the seeds in clean water for a day and a night, then remove and dry them, wrap them well in gauze, and put them in the refrigerator to force the seedlings, or use the most traditional method of hanging them in a well 40 cm above the water surface for germination. When 50% of the seeds have broken white, they can be sown. You can also use 5 mg/kg gibberellin seed soaking for chemical promotion of seedling emergence.

2. Prepare the seedbed: Apply base fertilizer at the bottom of the soil. Before sowing, the soil needs to be leveled and watered. When the water has seeped through all the soil, sow the seeds, then mix in a little fine sand and cover with 3 to 4 mm of nutrient soil. The soil must not be too thick. Finally, cover with a layer of film, which can play a role in heat preservation and waterproofing.

3. Transplanting seedlings: 6 to 7 days is the seedling-setting period. At this time, fertilizer needs to be applied once a week; per mu, this can be 10 to 15 kg of urea or ammonium sulfate. One day before transplanting, water in advance to make it easier to lift the seedlings, so they can be transplanted together with soil. The time chosen is roughly fine weather, preferably when there is not much sunlight, such as after 4 p.m., which is suitable for transplanting. When transplanting, pay attention to the spacing; it must not be too dense, and the depth should not expose the roots. Finally, water a little.

2. Water dropwort seed planting timing

1. Spring water dropwort seed planting timing

In cold regions, such as the Northeast, seedlings are usually raised from January to March, seedling setting is around March to April, and harvest is from May to July. The most suitable sowing period in the Yangtze River Basin is March. If sown too early, low temperatures are not conducive to growth; if sown too late, it will affect quality and yield.

2. Summer water dropwort seed planting timing

Summer is not suitable for planting water dropwort seeds, because summer weather is relatively hot and rainy, which will affect growth, cause seedling death, and reduce yield.

3. Autumn water dropwort seed planting timing

For autumn planting in the north, seedlings can usually be raised in early June to July, seedling setting is in early August to September, and harvest is from October to November. In the south, sowing is from July to early September, and the harvest time is from October to December. If late sowing is chosen, it can be harvested from March to April the following year. During this period, the south can plant in the open field, while the north needs greenhouse cultivation.

Water dropwort dryland cultivation techniques

1. Sowing and raising seedlings

1. Seedbed selection: Water dropwort likes a cool climate, and the seedbed needs relatively loose and thick soil with a certain fertility, convenient for drainage and irrigation. Per mu, 100 kg of lime can be poured in to turn the soil.

2. Soil preparation and bed making: The width is generally about 1 m. Per mu, 2,000 kg of manure can be applied, then dried, and finally the soil is leveled and broken up. It is also necessary to add 1,000 kg of carbofuran to eliminate earthworms in the soil.

3. Seed soaking and germination: Put the seeds in a cloth bag, hang the cloth bag with a rope, and suspend it in a well to soak for two days and two nights, or hang the seeds 0.5 m above the water surface for germination. Usually they will sprout in 3 to 4 days. If there is no water well, a freezer can be used for germination, that is, soak in clean water for a day and a night, then put it in the refrigerator.

5. Sow at the right time: Sow according to the season. Generally, autumn water dropwort needs to be sown from August to early September, while winter water dropwort is basically sown from September to late October.

6. Seedbed management: In good weather, water once every evening, while in relatively dry weather, water once in the morning and once in the evening. After the seedlings grow uniformly, start topdressing, once every 5 to 7 days. At this time, pest control is needed.

7. Soil preparation and fertilization: Cultivating water dropwort requires sandy soil. This kind of soil usually needs to be able to retain water. Add 150 g of quicklime per mu of soil, turn the soil, then add 20 kg of urea, 10 to 15 kg of potash fertilizer, and 40 to 50 kg of phosphate fertilizer, stir evenly, spread into the soil or water, level and refine it, and after 4 to 5 days it can be planted.

Water dropwort usually likes places with plenty of water, and a cool climate is very suitable for growing water dropwort. If you want water dropwort to grow vigorously and have high yield, there is no doubt that good planting techniques are needed. Controlling the planting time well is crucial for water dropwort.
