Japanese yellow onion cultivation method
Japanese yellow onion is a new variety introduced in our province in recent years. Due to its good quality and spicy taste, it has been welcomed by the market and its export volume has increased year by year. We now use Fengkang-1 as an example to talk about cultivation techniques. Feng Kang No.1 is a common fine variety. The yellow skin is medium-cooked, and the single fruit weight is 250-300 grams. The larger ones can reach 1500 grams or more and the per mu yield is about 3,000 kg. The standard of strong seedlings is 3 leaves and 1 heart, plant height is 20-25 cm, and false stems are 0.6-0.7 cm thick. The method of cultivating strong seedlings is to select fertile soil, and 2 to 3 years have not been planted with onions and garlic for soil preparation. Soil seedlings. Mushi high-quality fertilizer 5000 kg, 50 kg of phosphate fertilizer. Seed management should be fine. Seedlings should be kept moist before unearthing. Exposed seedlings of the roots should be filled with fine soil mulch. If the seedlings grow to 2 true leaves, they should be weak and combined with 5-7 kg of urea. It was found that underground pests used 800 times solution of dichlorvos or 1000 times solution of dimethoate in order to irrigate roots. If damages such as thrips and leaf miners were found, they could be sprayed with 1,000 times liquid dimethoate. Before transplanting, Mushi applied 5,000 kg of fertilized agricultural fertilizer, applied 50 kg of ternary compound fertilizer, and planted and ditched the field to facilitate irrigation and drainage. After the transplanting, the irrigation was conducted once for returning to Qingshui. After 5 to 6 days, rooting water was again poured. Immediately after the seedlings were transplanted, the planting spacing was 20 to 25 cm, the plant spacing was 15 to 20 cm, and the mu planting was 1.4 to 20,000 plants. Planting depth of 2 to 3 cm, to bury the bulbs, not lodging after watering, not floating seedlings is appropriate. Cultivated too deep unfavorable bulb expansion, planting shallow easy to lodging does not love to take root. Before returning green to swelled stems, Mushi 15 kg urea and weeding 3 times. In the 10 days before bulb expansion, there were 6 functional leaves that were poured with water once, and then seedlings were planted for 10 days to prevent the bulbs from affecting bulb enlargement. After seedlings is the key period of topdressing watering, watering should be diligent, small bulbs grow to 2 centimeters should Mu chase three yuan compound fertilizer about 15 kg, the bulb expansion period of appropriate amount of fertilizer, mu recovery urea 15 to 20 kg, twice The fertilization interval of 10 to 15 days, found that the first bolting should immediately remove the entire flower moss, but also the formation of bulbs, otherwise it will severely reduce production. Reduce the number of watering before maturity and stop watering 1 week before harvest. A 1 to 2 cm pseudostem was left on the bulb during harvest to prevent germs from invading the bulb causing rot.
