Five points of autumn green onion management

After the wheat harvest, it is time to plant autumn green onions. If you want to plant autumn green onions, you should pay attention to the five technical points before and after planting.

Choose excellent species to choose high-yield, high-resistance, strong-smelling, spicy, long-selling chicken scallions, high-footed white and other excellent winter storage green onion varieties.

Choosing the green onions is the most common practice. The folks have the saying that "spicy is spicy, must be simmered, and the onions and garlic do not meet each other". Therefore, in the arrangement of the sputum, the green onions cannot be duplicated with the vegetable crops of the Umbelliferae such as garlic, leeks and onions. It can be combined with crops such as cabbage, eggplant, melon, watermelon, cabbage and wheat. The plots for planting green onions should be made of soil with rich organic matter and deep soil layers. The terrain is high and dry, which is conducive to drainage. The green onions grown on such plots have good taste, spicy taste and high yield.

The yield of autumn green onions is high, and the demand for fertilizer is also large. In order to ensure the output and improve the quality, the base fertilizer should be applied. 5,000 tons of fertilized high-quality fertilizer + 50 kg of superphosphate + ternary compound fertilizer (sulfur-based compound fertilizer) 30 to 40 kg, spread the above fertilizer evenly on the surface of the shovel, then deep turn 20 to 30 cm, plow Ditching, the ditch is 30 cm deep.

The most suitable colonization time for the timely cultivation of autumn green onions in the plain area is generally in early July. The method of transplanting is often adopted. First, the seedbed is watered once every 2 to 3 days before the seedlings, so that the soil is kept dry and not wet, and it is not difficult to start the seedling, and it is not clay. With the seedlings, you can plant the seedlings. When planting the seedlings, the depth is not to bury the heart leaves, and it is better to expose 7 to 10 cm on the ground. Because the size of the onion is different, the lower part should be kept neat. Generally, 13,000 to 16,000 plants are planted in a high-yield field. The fertilizer should be thin, the thin ground should be dense; the fertilizer should be thin, and the fertilizer should be less dense. In order to facilitate soiling, a method of enlarging the line spacing and reducing the plant spacing should be adopted. The line spacing is more than 70 cm, and the plant spacing is 5-8 cm.

After the field management of the green onion seedlings is planted, the old roots quickly rot, and after 4 to 5 days, new roots can be sprouted, new roots grow, and new leaves begin to grow. The management objectives of this period are mainly to promote the development of the root system, one must prevent flooding; the second is to cultivate the loose soil and maintain the good permeability of the soil, which is conducive to the rapid growth of the root system. If there is water in the ditch after the rain, it will often cause yellowing of the onion leaves and dead roots. Therefore, it is necessary to drain and cultivate in time after the rain, strengthen the field management, promote the slow seedlings, and resume growth as soon as possible. (Wang Hu)
