How can onions be produced in high yield? Onion meat quality, tender and high-yield cultivation techniques
Onion is a dish that can be stored for a long time, and it is rich in nutrients. It can be fried, cold, etc. It is the best side dish for many dishes. Long-term consumption is very beneficial to the body. How can the onion be used to promote the meat? The following small series will tell you about the secret of high-efficiency onion cultivation.      First, the growth welcome request     1.1, soil Onion has strong adaptability to soil, and it is suitable for fertile and loose. Among them, sandy loam is easy to obtain high yield, while clay loam is full of bulbs and is resistant to storage.     1.2, moisture Onions should be supplied with sufficient water during germination, seedling growth and bulb expansion. But before the winter, you should control the water to prevent the seedlings from freezing damage. Drought-tolerant, suitable for 60 to 70% humidity, high humidity is prone to disease.     1.3, lighting Onion is a long-day crop. It needs sufficient sunshine conditions to grow normally during growth. The suitable light intensity is 20,000 to 40,000 lux.     1.4, temperature Onions are more adaptable to temperature. Seeds and bulbs can slowly germinate at 3 to 5 °C. Bulbs require higher temperatures, but when the temperature is too high, they will grow and fall into dormancy.     Second, the variety selection     2.1, white onion Onion white, fleshy, white, oblate, good quality, suitable for dehydration processing or canned food ingredients. However, the yield is low and the disease resistance is weak. It is premature in the autumn of the Yangtze River, and it is easy to convulse in advance. Representative varieties include Hami white skin and so on.     2.2, yellow onion The onion is brassy to pale yellow, and the scales are fleshy, yellowish and soft, and the flavor is strong. It is oblate and has a diameter of 6 to 8 cm. More resistant to storage, transportation, early maturing to medium maturity.     2.3, red onion The onion is purple in appearance and the scales are slightly reddish. Resistant to storage and transportation, from early maturing to medium maturity. It is widely cultivated throughout East China. Representative varieties are Shanghai Red Leather and so on.     Third, field management     3.1, loose soil Loose soil is beneficial to the development of onion roots and the expansion of bulbs. Generally, the seedling stage should be carried out 3 to 4 times, combined with each watering, and the plants are stopped after ridge cutting.     3.2, fertilization Onion requires 13-15 kg of nitrogen per acre, 8-10 kg of phosphorus, and 10-12 kg of potassium. Avoid excessive nitrogen fertilizer. In the period of leaf growth and bulb expansion, fertilization and watering should be applied in time, and 15 kg of diammonium phosphate, 20 kg of diammonium phosphate and 3 to 5 kg of potassium sulfate should be applied per mu.     3.3, watering After about 20 days after the onion is planted, it enters the slow seedling period. At this time, it is not possible to water a large amount of water. Too much watering will lower the ground temperature and slow the young seedlings. At the same time, the number of watering at each stage of planting seedlings is small, so as to promote the rapid development of seedlings.     3.4, in addition to è–¹ For the early twitching onion, before the flower ball is formed, it is cut off from the lower part of the flower bud, or separated from the tip of the flower bud , and two pieces are torn from top to bottom to prevent flowering from consuming nutrients, promoting side bud growth and forming a more substantial bulb. Spray the fruit and fruit at the right time. Practice has proved that for the plants that are previously convulsed, certain yields can still be obtained after removing the mites.     Fourth, harvest     4.1, picking time Onion harvesting is generally from the end of May to the beginning of June. When the onion leaves turn yellow, the pseudo stems become soft and begin to fall, indicating that the bulbs are mature and should be harvested in time.     4.2, harvesting and drying After the onion is harvested, it should be aired in time, and the onion plants should be arranged diagonally to avoid direct exposure of the onion to the sun. Turn it every 2 to 3 days and let the leaves turn yellow. Onion is a very easy-to-plant dish. You only need to pay attention to water and fertilizer management and field management during planting. The above is the detailed onion meat quality, high-yield cultivation skills, you can learn from.
