The Dutch bean, commonly known as vegetable pea, is an emerging special vegetable in recent years. It is popular for its delicious taste and has now become an indispensable fine dish for urban and rural family meals. The Dutch beans are generally cultivated in the autumn. Therefore, the management of winter field management is the key to seize the high yield and efficiency of the Dutch beans. Generally, the following five passes are required.

1. Manage water and fertilizer. Do not water before emergence, after the emergence of the vegetative growth period, dominated by cultivator weeds, proper watering, as long as no cracking can be. The creeping species is strung across a length of 30 cm. Sprinkle water before budding and water without flowering. Dutch beans have nitrogen-fixing ability and do not require many fertilizers, but most varieties have strong growth potential and high planting density. Generally, they need top-dressing 3 times, the first time they are used for long-term use in pumping mangoes, 15 kg of compound fertilizer for Mushi, or 4000 kg of human waste. ; Phosphorus and potash topdressing stage, 15 kg of Mushi DAP, 5 kg of potassium sulfate or potassium chloride, significant increase in production.

2. Sparse topping. When the plant grows to 15 knots, it will be picked up and the old leaves and yellow leaves will be removed to improve the ventilation and light transmission conditions. To prevent falling flowers, 30 mg/L of anti-dropping agent can be sprayed.

3. Scientific management. About 20 days after the emergence of the Dutch beans, generally has entered the cold winter, when the seedlings have strong cold resistance, but still have to pay attention to antifreeze, cold spray can be sprayed on the foliage; spring temperature rise, the film can be removed, timely cultivator Loose soil, increase ground temperature, apply nitrogen fertilizer 7-8 kg, apply small water in time after top dressing, but do not flood irrigation; in the flowering period can be sprayed "920", etc., keep flowers to protect crops, increase production.

4. Prevent pests. The Dutch bean is endangered by cabbage caterpillars and cockroaches during the entire growth period and can be controlled with the use of hydropermethrin and dicofol. The main diseases are virus disease and rust disease. The main prevention and treatment is the use of virus or virus K and triadimefon and copper preparations. The drug is administered every 3 to 7 days, depending on the severity of the disease.

5. Harvest timely. After 7 to 10 days after flowering, the pods are ready for harvesting. They should be harvested and marketed in time. Harvesting should take place 1-2 days earlier. Seedlings can be seen in pods but not flattened. And broken soybean meal, sprayed with 20 mg/kg B solution to treat pods, can inhibit chlorophyll degradation, enhance freshness and commercial quality.
