After the beginning of autumn, the rapid growth period of autumn scallions has entered. At this stage, field management needs to be strengthened. Soil cultivation is an important part of management. Scientific soil cultivation can prevent autumn scallions from falling, increase the length of scallions, prevent scallions from bending, and increase yield. Improve quality. Pay attention to the following three points in production management: 1. Master the appropriate time The soil cultivation time should be carried out when the height of the green onion plant is about 30 cm. It is calculated according to the growth period. In North China, the first soil cultivation is generally carried out after the beginning of autumn, and the soil cultivation is carried out again every half month, and lasts until early and mid September for the entire growth period. Need to cultivate 3 times. 2. Avoid damage to roots and leaves When taking soil, the hoe should keep a proper distance from the root system of the green onion, and not too close to the root system to avoid damage to the root system. Cultivation is generally carried out at 4 to 6 in the afternoon, because the leaves of green onion are crisp and tender in the morning, and they are easily damaged by machinery. In the afternoon, the leaves are soft and not easily hurt. Keep the pseudostems of the green onions upright each time you cultivate the soil, and don't let the soil cover the heart of the green onions, otherwise it will cause the green onions to bend and affect normal growth. Three, balance topdressing Each time soil cultivation combined with topdressing can increase the commodity and yield of green onions. For the first soil cultivation, 50 kilograms of decomposed soybean meal fertilizer and 10 kilograms of sulfur-based compound fertilizer with a content of 45% N, P, and K (1∶1∶1) per mu can be combined with each mu; The demand is great. Topdressing 100 kg of decomposed soybean meal fertilizer + 40 kg of nitrogen and potassium fertilizer or 35 kg of high-nitrogen and high-potassium compound fertilizer; the third application of 30 kg of calcium nitrate in soil cultivation can promote the growth of green onion and thicken the plant to increase resistance Reverse capacity and increase output.
