(1) Cultivate strong seedlings, pod peas can be cultivated with varieties that are resistant to low temperature, disease resistance, high yield, good pod quality, and beautiful appearance, such as pods, large pods, and so on. Seedling transplanting is usually used. The age-appropriate seedlings should have 4 to 6 true leaves and short stems. Such seedling age is about 20 to 25 days at a high temperature (20 to 28 ° C), about 25 to 30 days at a suitable temperature (16 to 23 ° C), and about 30 to 40 days at a low temperature (10 to 17 ° C). The seedling period of each time can be determined according to the planting period and the temperature of the greenhouse. The nursery bed soil is required to prepare nutrient soil, and the root-preserving method such as nutrient meal, paper bag or nutrient earthwork is adopted. Pour the bottom water before sowing, dry seed sowing, 2 to 4 seeds per hole. After the sowing, the temperature is controlled at 10~18 °C, so that the seedlings can be emerged quickly and emerged. The temperature is low and the germination is slow, and the temperature is high (25 to 30 ° C). Although the germination is fast, it is difficult to preserve the seedlings. The cotyledon stage temperature is preferably 8 to 10 °C. Before planting, the seedlings should be subjected to a low temperature of about 2 °C to complete the vernalization stage.
(2) Site preparation: 5,000 kilograms of high-quality farmyard manure per 667 square meters, 40-50 kilograms of superphosphate, 50-60 kilograms of grass ash, 20-25 cm deep and fully mixed with soil.耙 耙 耙 畦 畦 畦 畦. When planting in a row, the raft is 1 meter wide and planted in a row; when double rows are densely planted, the raft is 1.5 meters wide and two rows are planted; when the raft is interspersed with the cold-tolerant leafy vegetables, the ridge is 1 meter wide and two rows are planted.
(3) When the planting is planted, the ditch is ditched, the ditch depth is 12 to 14 cm, the single-row dense planting hole is 15 to 18 cm, and the 667 m2 is planted with 3000 to 3600 points. The double-row dense planting distance is 21 to 24 cm, and 4,500 to 5,000 holes are planted per 667 square meters. The interval between the gaps is 15 to 18 cm, and 6000 to 7000 holes are planted per 667 square meters. Sit in water and plant the seedlings.
(4) Field management 1 Temperature management After planting until the buds bloom, the temperature exceeds 25 °C during the day, and should not exceed 30 °C, and not less than 10 °C at night. The whole pod-forming period is 15 to 18 ° C during the day and 12 to 16 ° C during the night. 2 Water and fertilizer management After planting water, it is generally no longer watering the seedlings. Do not topdress before the bud. However, it is necessary to timely cultivate the soil to increase the temperature and ensure the root development. After the bud, the water is washed once with manure or fertilizer, and the compound fertilizer is 15-20 kg per 667 square meters. Then, a shallow cultivating was carried out on the surface to control the pods. The first flower is formed into a small pod to the second flower. The sign of the second flower is marked to enter the flowering stage of the pod. At this time, the amount of fertilizer and water needs to be large. Generally, the fertilizer water is poured once every 10 to 15 days, and the nitrogen fertilizer is applied every 667 square meters. Potassium compound fertilizer 15 ~ 20 kg, or urea 10 ~ 15 kg, superphosphate 20 ~ 25 kg, and the application of plant wood ash 50 kg per 667 square meters of potassium. This period of lack of fertilizer water will cause falling flowers and pods. 3 Brass peas stems are soft and hollow, and are easy to break. At the same time, their stems are not like beans and kidney beans, and they are not easily tied like cucumber stems. Therefore, when the plants grow to tendrils, bamboo rafts are needed. The method of combining with the rope is used to support the beans so as to climb each other.
(5) Harvesting of most varieties 8 to 10 days after flowering, the pods stopped growing and the seeds began to develop. This is the tender harvest of the tender pods. Sometimes it is slightly increased in some yields, and the seeds are developed to a certain extent and then harvested, but the quality of the harvested pods is deteriorated.
