Dutch bean seed sowing time and planting techniques! The response of Dutch beans in the vegetable market is very good. At present, the cultivation of peas has spread all over the north and south of China. However, for the cultivation technology of peas, due to the continuous development of agricultural technology, there are always some technical essentials that cannot be completely controlled by everyone. Made some sorting here.
Dutch bean planting technology
1. Soak the seeds and take an appropriate amount of pea seeds. The day before planting, water should be soaked for 8-12 hours.
2, the seed sowing seeds should be drained before sowing seeds. Sowing on an on-demand basis, put one pea seed at each point. The spacing between each seed is 20 cm.
3. Cover the soil and water it, put a thin layer of soil on the seed, and water it until it is poured.
4. After about 3 to 5 days of germination, it will germinate.
5, sparse seedlings depending on the situation, if the plant grows too dense, still need to sparse seedlings, the most appropriate distance is more than 20 cm.
6, topdressing peas fertilizer demand is large, 20 days after the topdressing, and then every 10 days, then topdressing once, try to be a small number of times. After about 20 days, when the pea seedlings grow to a height of about 15-20 cm, the stand is started to prevent the plants from falling over.
7, after harvesting and flowering, it can be harvested in about 20 days.
Dutch beans mature in a few months? April is the season when peas mature. Generally farmers will choose to pick and sell at this time.
Dutch bean growing environment
1, lighting requirements
Dutch bean is a long-day plant. Most varieties can bloom early when the light is extended, and delay flowering when the light is shortened, but some early-maturing varieties do not have strict illumination requirements. In general, the varieties require strong light and long-term sunshine during the pod-forming period, but it is not suitable for high temperature, and it is suitable for planting in spring and summer.
2, water demand
Dutch beans require more water throughout the growing season. During the germination process of the seed, if the soil moisture is insufficient, the seed can not absorb water and swell, which will greatly delay the emergence period. The seedling period can endure a certain arid climate. If the air humidity is too low during the flowering period, it will cause the flowers to fall. In the growth period of the pod, in case of high temperature and drought, the pod fiber will be hardened early, prematurely matured to reduce quality and yield.
Therefore, during the whole growth period of the peas, there must be sufficient water supply to grow vigorously, the pods are full, and the quality and quantity are guaranteed. However, it is not resistant to cockroaches. If the water is too large, it is easy to rot seeds after sowing, and it is easy to rot at the seedling stage.
3. Soil conditions
Dutch beans are not strict with soil requirements. They can be planted on well-drained sandy soil or in new land. However, it is advisable to loosen neutral soil containing organic matter and grow in soil with pH 6.0-7.2. When the soil acidity is lower than ph5.5, it is easy to disease and reduce the rate of pod formation. The roots of the Dutch bean are deep, slightly drought-tolerant and not resistant to moisture. The sowing or seedlings are poorly drained and easily rotted, and the drought is poorly fertilized, which is easy to form empty pods or pods. Dutch beans avoid continuous cropping, usually at least 4-5 years of rotation.
4, cultivation timing
Dutch beans can be divided into three types according to their growth habits: dwarf, orchid, and vine. The Yangtze River Basin is cultivated in spring and planted in mid-to-late February. Cultivation in autumn, sowing in mid-to-late August. Wintering cultivation will be planted in late October to early November. The spring is generally cultivated in spring and summer, and can also be used in early spring and autumn cultivation.
Main points of cultivation techniques in Dutch bean greenhouse
1. Planting on the ground. Mainly by live broadcast, ridge or simmering, apply 2000 kg of organic fertilizer and 20 kg of superphosphate before sowing. In order to promote early maturing and lowering flowering nodes, soaking seeds can be germinated before sowing, soaking for 2 hours at room temperature, 5 to 7 days at 5 °C to 6 °C, sowing when the buds grow to 5 mm, and after sowing seeds Watering should be done in time. Take the strip, the spacing is 30 ~ 40 cm, the plant spacing is 8 ~ 10 cm, the soil is 2 ~ 3 cm, the amount of dwarf species per acre is 15 kg, and the species of vine is 12 kg.
2. Field management. Do not water before emergence, nutrition after the emergence of seedlings, mainly cultivating sorghum, properly watered, not dry. The vines are planted when the vines are 30 cm long. Pour small water before the buds and do not water during the flowering period.
Dutch beans have nitrogen-fixing capacity and do not need a lot of fertilizers, but most varieties have strong growth potential and high cultivation density. Usually, they need to be topdressed 3 times. For the first time, they should be applied for long-term application, 15 kg of compound fertilizer, or 400 kg of human excrement. In the pod-forming period, the application of phosphorus and potassium fertilizer, the application of 15 kg of diammonium phosphate, 5 kg of potassium sulfate or potassium chloride, the effect of increasing production is obvious.
When the plant grows to 15 knots, the heart is removed, and the lower old leaves and yellow leaves are removed to improve the ventilation and light transmission conditions. To avoid falling flowers, a spray of 30 mg per liter of anti-fall can be used.
The ripening time of Dutch beans and peas is similar, and it is almost mature at the end of the spring, so people who love peas must not miss the freshest glimpse. In addition, peas are now a vegetable that can be grown all year round. Therefore, people who love Dutch beans can eat peas all year round.
