First, nursery. The seeds of the bean are smaller, and the cold resistance is weak. Selecting the seeds before sowing is the key to ensure the seedlings are full and the seedlings are strong. In the past, beans were mostly broadcasted in the past. In recent years, seedling transplanting methods have been implemented in greenhouses to fully protect the root system from damage. It is easy to arrange the upper and lower jaws. Not only early sowing and early harvesting, but also early supply of the market can be ensured. Practice has shown that seedlings can increase production by 27.8% to 34.2% compared with direct seeding, and mention the city for 10 to 15 days. The stems of live beans grow vigorously with less pods, and more seedlings are transplanted. In other words, the bean pods are transplanted by seedlings and can inhibit vegetative growth and promote reproductive growth. Physiologically speaking, the bean seeding stage is under short-day sunlight, and it is beneficial to promote flower bud differentiation, so the flowering and podging area is low. Transplanting seedlings mostly use small plastic bags and paper tubes (paper baskets) to raise seedlings. It is also possible to use 55 cm nutritious soil cubes to raise seedlings, with 2 to 3 seeds per hole, irrigating the water, and paying attention to heat preservation and control. The nursery period should be calculated based on the picking time of the previous vegetable. The seedling age is generally 20-25 days. Generally before and after the winter solstice. In order to facilitate seed germination and kill the eggs and germs attached to the seed coat, high-temperature sterilization “seeds†are used for sowing. That is, the seeds are first selected, placed in a pot, and the seeds are quickly hot-pressed with hot water at 80° C.-90° C., then the cold water is added to cool the temperature, and the water temperature is maintained at about 25° C.-30° C. for 4-6 hours, and the fish is used for drying and sowing. Generally no longer sowing germination.
Second, the basal fertility and soil preparation. The soil with deep soil and deep layers of soil should be deep-turned 25 cm before sowing, combined with 5,000-10,000 kilograms of soil-fertilizers, 50-75 kilograms of superphosphate, 50 kilograms of diammonium phosphate, and 15-25 kilograms of potash. After the preparation of soil preparation, the lotus root is 1.2-1.3 meters wide, and each row is transplanted with two rows of beans, about 20 centimeters in diameter, and 2 plants per hole. 5500-5000 piers per mu.
Third, insert racks, topping, snoring. After the beans are thrown into the vine, the scorpions of the first spike can be completely wiped off. When the main vine climbs to the top of the rack, it is picked up and the later side branches are also plucked. The main vine toss the heart to promote the development of lateral branches, and wipe the pods and side branches to improve the growth of the beans.
Fourth, first control and promote management. Bean root is deeply tolerant to drought and grows vigorously. It is more prone to vegetative overgrowth than other legumes. In combination with greenhouse cultivation, the light is weak, the temperature is high, the fertility is sufficient, and the vegetative growth is more prominent, which in turn affects flowering and scab. Field management must be controlled first and then promoted to prevent stems and leaves from becoming long and premature. Before transplanting to flowering, the bean pods were mainly controlled with water and cultivating roots, and appropriate seedlings were promoted to promote flowering and podging. After the pods were used, sufficient water was supplied to increase the number of flowering and scabs. The specific approach is: after transplanting seedlings to raise seedlings and easing seedlings, the seedlings will be cultivated immediately to raise temperature, promote root development, and control stems and leaves. After the emergence of buds can be poured small water, and then cultivator. No watering at the beginning of flowering. When the first inflorescence blossoms, after several inflorescences appear, you must pour enough water. After the head water, the stems and leaves grow rapidly, and when the middle and upper inflorescences appear, the water is poured again for the second time after the middle and upper inflorescences appear. Afterwards, it enters the clams stage, and when it is dry, it is watered to obtain high yield. Harvesting period, with the water once fertilizer, Mushi high-efficiency fertilizer, diamine 50 pounds or potassium dihydrogen phosphate 22-25 kilograms.
