1.Soil preparation
Mainly direct broadcasting, ridge or mowing, 2,000 kg of organic fertilizer and 20 kg of superphosphate were applied to the acres before sowing. In order to improve early maturity and decrease flowering nodes, you can soak the seeds to promote germination before sowing, soak the seeds for 2 hours at room temperature, and leave them for 5 to 7 days at 5 ° C to 6 ° C. When the buds reach 5 mm, sow. Be watered in time. By seeding, the row spacing is 30 to 40 cm, the plant spacing is 8 to 10 cm, the soil cover is 2 to 3 cm, the dwarf seed per mu is 15 kg, and the vine is 12 kg.
2. Field management
Do not water before emergence, vegetative growth period after emergence, mainly cultivating barnyardgrass, watering properly, not cracking. Overgrown species are erected when the vine is 30 cm long. Pour small water before budding, no watering during flowering.
Dutch beans have the ability to fix nitrogen and do not require many fertilizers, but most varieties have strong growth potential and high cultivation density. Usually, they need to be topdressed 3 times. The first time is long-term application at Suwanwang, 15 kg of compound fertilizer per mu, or 400 kg of human urine ; In the pod-setting stage, topdressing phosphorus and potassium fertilizers, applying 15 kg of diammonium phosphate per mu, and 5 kg of potassium sulfate or potassium chloride, the effect of increasing yield was obvious.
When the plant grows to 15 knots, remove the old leaves and yellow leaves to improve the ventilation and light transmission conditions. To avoid falling flowers and pods, a spray of 30 mg per litre can be used.
3. Pest control
Dutch beans are prone to aphids, leaf miners, rust and powdery mildew during their growth. For aphids and leaf miners, 40% dimethoate EC 1000 times solution and 80% dichlorvos EC 1000 times solution can be used to prevent and control. For legume rust, 1000 times solution of 50% rust rust wettable powder can be used.
