Autumn scallions are a kind of autumn vegetables grown in large areas in our province. At present, it is time for vegetable farmers to plant autumn green onions. Here are five technical tips for the vegetable farmers before and after the autumn green onion planting for your reference. First, choose the best species In the main producing areas of autumnal onions in the south-central part of our province, we can choose varieties of excellent winter storage green onions, such as Longfeng chicken onion and Gaojiabai, which have good yield, strong disease resistance, and spicy taste. Second, select plots The green onions are the most intimidation of continuous cropping, and can not be weighed with vegetables such as garlic, leeks, onions, etc., and can be connected with crops such as cabbage, eggplant, wax gourd, watermelon, cabbage, and wheat. The plots on which green onions are grown should be rich in organic matter. The soil with deep soil layers is appropriate. The terrain is high-dry and is conducive to drainage. The green onions from such plots have good taste, spicy taste and high yield. Three, soil fertigation The output of autumn scallions is high and the demand for fertilizers is also relatively large. In order to ensure yield and improve quality, base fertilizer should be applied. Mushi rotated farmyard fertilizer 5000 kg + superphosphate 50 kg + ternary compound fertilizer (sulfur-based compound fertilizer ) 30 to 40 kilograms, spread the above fertilizer evenly on the surface, then deepen 20 to 30 centimeters, use a plough to open the ditch, ditch 30 cm deep. Fourth, timely planting In the middle and southern plains of our province, suitable time for planting autumn green onions is generally in early July. Transplanting methods are often used. First, water is poured on the seedbed 2 to 3 days before the seedlings are lifted to keep the soil dry and wet. It is not difficult to lift the seedlings and it is not clayy. Do with the seedlings, with the planting seedlings. When planting seedlings, depth is not buried in the heart, on the ground exposed 7 ~ 10 cm is appropriate, because the size of onions and oysters are different, to keep the lower neat and consistent. Generally, high-yielding fields cover 13,000 to 16,000 planted acres. Fertilizers should be thin, thin and dense; fat should be thin, fat should be less dense. In order to cultivate the soil conveniently, the methods of enlarging the row spacing and narrowing the plant spacing should be used. The row spacing is controlled at about 70 cm, and the spacing between plants is 5 to 8 cm. V. Field Management After the green onion seedlings are planted, the old roots will soon rot, and new roots will sprout after 4 to 5 days. New roots will grow and new leaves will begin to grow. The management objectives of this period are mainly to promote the development of the root system; one is to prevent flooding; the other is to cultivate loose soil, maintain good permeability of the soil, and facilitate the rapid growth of the root system. If there is water in the trenches after the rain, it will often cause yellowing of the onion leaves and rot-root dead seedlings. Therefore, timely drainage and cultivating after the rain shall be carried out to strengthen field management, promote the easing of seedlings, and restore growth as soon as possible.
