Although the reproductive process of welsh onion is relatively simple, the technical requirements of field management are relatively high. In order to achieve high yield and high quality, the management measures are summarized as follows:
1. Early planting and early transplanting, and proper planting is the key. Many years of production experience have shown that early transplanting welsh onion has significantly improved yields compared to late transplanting onion. In addition, reasonable close planting is an important measure for high quality and high yield of welsh onion, generally with a plant spacing of 4-6 cm and a row spacing of 25-30 cm.
2. Weeding grass should be timely to prevent locusts from causing rot. The cultivator can promote the growth of welsh onion roots and increase the permeability of the soil. Onion cultivars are in season when the temperature is high and the rainfall is heavy, and there are many kinds of weeds. Therefore, weeding must be done in time to prevent the grassland; in July and August, the northern region is concentrated. During the rainfall period, it is easy to cause scallions roots, yellow leaves, and dry tips. In addition to preventing waterlogging, it is also necessary to break the table and scatter early so that the roots of scallions can perform various normal activities.
3. The top-dressing fertilizer should be applied properly, and high yield and quality are guaranteed. Based on the fertility characteristics of local green onions and the local fertilization habits, generally 30 kg of “Tianji†phosphorus and potassium nitrate are applied per acre, and 30 kg of “Tianji†phosphorus nitrate is applied in 7-8 months, and then applied in the following month. 25 kg of Phosphorus Nitrate.
