Whether there are netizens to help introduce green onions in the planting process, reasonable soil cultivation is very important, can increase the length of green onions, prevent lodging and bending, at the same time can greatly improve the taste and quality of green onions, enhance the value of green onions. Soil cultivation is an important measure to soften leaf sheath, prevent lodging and improve the yield and quality of onion. The cultivation of soil must be carried out in the green onion formation period, otherwise it is easy to cause root and plant rot. Soil cultivation should be gradually thickened according to the age of seedlings, but if the soil cultivation is unreasonable, it can cause green onions to burn roots, green onions bending and so on. Therefore, the farming network sorted out the matters that need to be paid attention to when cultivating soil with green onions, which are listed below for netizens' reference. Important point 1, green onions soil cultivation time: when green onions grow to 30 centimeters before soil cultivation, not too early, otherwise it can cause green onions to grow slowly and green onions bend; soil cultivation should be carried out in the afternoon, because the leaves are tender, otherwise it is easy to cause leaf damage. Point 2, soil cultivation and appropriate amount of topdressing: green onions generally carry out soil cultivation for 3 times in the process of growing in their lifetime. It becomes "small cultivation" for the first time, and the thickness of soil cultivation is controlled at about 5 cm. After green onions grow to 30 cm, 25 jin of balanced compound fertilizer such as 15-15-15 type compound fertilizer combined with 150 jin of organic fertilizer can be applied to promote deep root growth and meet the early growth needs of green onions. Scallions grow to 40 to 45 cm to carry out secondary soil cultivation, the soil thickness is controlled at about 10 cm. This time, the topdressing of soil should be based on nitrogen and potassium fertilizer, and 15-5-20 high nitrogen and high potassium type can be selected to promote the growth of pseudostem and leaves, combined with 250 jin soybean meal organic fertilizer. The last soil cultivation is about 20 days before harvest, in order to improve the green onion quality and taste, the soil thickness is controlled at about 10 cm, and 50 jin of calcium nitrate can be applied at the same time. This topdressing should not be supplemented with nitrogen fertilizer, otherwise it will easily lead to green onions becoming soft and taste bad. Third, the method of cultivating soil with green onions: do not take the soil width too wide, take the soil from the middle of the row, do not exceed 1/3 of the line spacing, and do not be too deep, so as not to hurt the roots; the soil should be solid to prevent rain or watering collapse; the soil should not be cultivated if the soil is too dry and wet; to keep the green onion pseudostem straight, and do not cultivate the soil too deep, the deepest buried to the leaf sheath, otherwise it is easy to lead to green onion bending. Fourth, the choice of soil cultivation season: do not cultivate the soil in the high temperature season, otherwise the pseudostem is buried in the soil too deep and easy to rot. The number of times of soil cultivation should not be too much. Frequent soil cultivation not only increases the workload, but also inevitably hurts the roots and leaves, affecting the growth and accumulation of Welsh onions. Do not cultivate the soil too deep at once, otherwise, if you bury the functional leaf itself, it will easily cause the leaf to rot. Each time the thickness of the soil is 3cm to 4cm, the soil is cultivated to the boundary between the leaf sheath and the leaf body, that is, only the leaf sheath is buried, not the leaf.
