Planting techniques of Dutch beans the Dutch beans are mature in a few months.

The response of Dutch beans in the vegetable market is very good. At present, Dutch beans have been planted all over the south and north of China, but for the cultivation technology of Dutch beans, due to the continuous development of agricultural technology, there are always some technical essentials that can not be completely controlled, so the editor has made some arrangement here.

Planting techniques of Dutch beans

1. Soak the seeds and take the right amount of pea seeds. Soak in water 8-12 hours the day before sowing.

2. Soaked seeds should be drained before sowing. Sow seeds on demand, with 1 pea seed at each point. The distance between each seed is 20 cm.

3. After covering the soil and watering the seeds, gently apply a thin layer of soil, and water until thoroughly.

4. After germinating about 3-5 days, it will germinate.

5, thinning seedlings depends on the situation, if the plant growth is too dense, still need to thinning seedlings, the most appropriate distance is more than 20 centimeters.

6. There is a great demand for topdressing peas, which should be topdressing after 20 days, and then once every 10 days, as many times as possible. After about 20 days, when the pea seedlings grow to a height of about 15-20cm, scaffolds should be erected to prevent the plants from tipping.

7. It can be harvested about 20 days after the harvest.

How many months the Dutch beans are ripe

April is the season for Dutch beans to ripen. The average farmer will choose to pick and sell at this time.

The growing environment of Dutch bean

1. Lighting requirements

Long-day plants of the genus Holland beans. Most varieties can blossom earlier when the light is prolonged and delayed when the light is shortened, but some early-maturing varieties are not strict with the light. General varieties require strong light and long-term sunshine during the podding period, but they are not suitable for high temperature and are suitable for planting in the alternating period of spring and summer.

2. Water demand

Dutch beans require more moisture throughout the growing season. In the process of seed germination, if the soil moisture is insufficient, the seed can not absorb water and expand, which will greatly delay the emergence of seedlings. The seedling stage can tolerate a certain dry climate. If the air humidity is too low during flowering, it will cause flowers and pods to fall. In the case of high temperature and drought during the pod growth period, the pod fiber will harden earlier and mature prematurely, thus reducing the quality and yield. Therefore, in the whole growing period of Dutch beans, there must be sufficient water supply in order to grow vigorously, with large pods and full seeds, ensuring quality and quantity. But it is not resistant to waterlogging, if the moisture is too large, the seeds are easy to rot after sowing, the roots are easy to rot in the seedling stage, and the disease is easy to occur in the growing period.

3. Soil conditions

Although Dutch bean is not strict on soil, it can be planted on sandy soil or newly reclaimed land with good drainage, but it is suitable to grow in pH6.0-7.2 soil and loose neutral soil containing organic matter. When the soil acidity is lower than ph5.5, the disease is easy to occur and the pod setting rate is reduced, so lime should be added to improve it. Dutch bean has deep roots, slightly tolerant to drought but not resistant to moisture, poor drainage of sowing or seedlings, poor drought and fertilization at flowering stage, and easy to form empty pods or blighted pods. Dutch bean bogey continuous cropping, generally at least 4-5 years rotation.

4. Planting and sowing time

According to the growth habit of its stem, Dutch bean can be divided into three types: dwarf, orchid vine and vine. In the Yangtze River valley, it is cultivated in spring and sown in mid-late February. Planted in autumn and sown in mid-late August. Overwintering cultivation sowed one after another from late October to early November. In the north, it is generally ploughed in spring and harvested in summer, but it can also be cultivated in early spring and autumn.

Key points of cultivation techniques of Dutch Bean in greenhouse

1. Prepare the soil and sow seeds. To direct seeding, ridge or border cultivation, 2000 kg of organic fertilizer and 20 kg of superphosphate were applied per mu before sowing, and ridges or beds were made after ploughing and leveling. In order to promote early maturity and decrease the flowering node position, the seeds should be soaked to promote germination before sowing. The seeds should be soaked for 2 hours at room temperature and placed for 5 days under the condition of 5 ℃ ~ 6 ℃. When the buds grow to 5 mm, the dry seeds should be watered in time. Strip sowing is adopted, with row spacing of 30 cm to 40 cm, plant spacing of 8 cm, covering soil of 2 cm, 15 kg of dwarf species per mu and 12 kg of trailing species per mu.

2. Field management. No watering before emergence, vegetative growth period after emergence, mainly ploughing and weeding, properly watering, not dry and cracked. The trailing species set up when the vine is 30 centimeters long. Pour a little water before the bud, but don't water it during the florescence.

Dutch beans have the ability of nitrogen fixation and do not need a lot of fertilizer, but most varieties have strong growth potential and high cultivation density, and they usually need topdressing for 3 times, and apply compound fertilizer 15 kg per mu or human fecal urine 400 kg per mu for the first time. 15 kg of phosphate potassium fertilizer, 15 kg of diammonium phosphate per mu and 5 kg of potassium sulfate or potassium chloride per mu can obviously increase the yield.

When the plant grows to 15 nodes, the heart is removed, and the lower old leaves and yellow leaves are removed to improve ventilation and light transmission conditions. In order to avoid falling flowers and pods, you can use 30 mg per liter of anti-falling hormone spray.

The ripening time of Dutch beans is similar to that of peas, which begins to mature at the end of spring every year, so people who love Dutch beans must not miss the freshest crop. In addition, Dutch beans are now a vegetable that can be grown all year round, so people who love Dutch beans can eat them all the year round.
