Qin Xuan No. 1 pea planting technology
In 2003, the new pea variety “Qin Xuan No.1†was introduced in Luquan City, Hebei Province, and the trial plantation was carried out in South Ganzi Village. The main advantages are: high-yield, lodging-resistant, concentrated seedlings, consistent maturity, scale planting, suitable for mechanical harvesting, high-yield and high-yield crops that can be transplanted and interplanted with cotton and yam. First, the characteristics of "Qin Xuan No. 1" peas, the growth period of 90-100 days, about 70 cm plant height, more than 200 grams of grain weight, 300-400 kg per mu. If the dish is used, it can receive 900-1200 kilograms of green peas. Cold resistance, more resistant to powdery mildew, the biggest feature is that all the leaflets become developed tendrils, inter-plant intertwining between the plants, forming a high resistance to lodging, ventilation, light, stable overall structure, to overcome the low pea peasant rain lodging The drawbacks of budding. Second, the cultivation techniques 1, timely early sowing: suitable for early spring Ling top sowing, time to sow at the end of February early March is better. 2. Applying base fertilizer: When planting Mushi farmyard fertilizer 3-4, N, P and K each containing 15% compound fertilizer 40-50 kg. 3. Seeding rate and sowing method: General sowing rate of 12-15 kilograms, 4-5 million per mu seedlings, sowing method can be used 6-8 small lines, a large line, small lines 20-25 cm, large lines 40 cm Fortunately, Daehang is mainly to facilitate field management. 4. Field management: After peas are planted in spring, they should loose soil once, increase ground temperature, promote rooting, and then cultivate once a week. The flowering period needs to be watery and sensitive, and this key water yield increase effect is significant, before flowering. If there is insufficient moisture at the bottom, the water should be poured once the air is dry to meet the needs of flowering and podging. Excessive water during the flowering period, the plants are too long, there is a phenomenon of falling too dry. During the pod stage, water is poured once more, increasing the number and number of pods. 5. Prevention of pests and diseases: Pea pests are mainly leafminers, aphids, and peas. The prevention and control of leaf miner larvae is critical, and the appropriate period for the first time in mid-April is better. The agent can be sprayed with 1,000 times higher effective hydrogen-permethrin, 30-40 kg per mu, and the effect is better after 10 days. Prevention and control of peas can be sealed and fumigated with dried beans after harvest. The agent is preferably aluminum phosphide. Powdery mildew is the main pest of peas. Although "Qin Xuan No. 1" peas are more resistant to powdery mildew, they can also cause diseases when rain meets high humidity in the late growth period. Trimethinone can be used once or twice to control the disease.
