Do you know the choice of soil for farmers to grow vegetables, green onions and the number of times they cultivate soil?

Farmers who have planted green onions should know that green onions have strong adaptability to the soil, whether sandy loam or clay loam can be cultivated, but the organic content of sandy loam is low, and the water and fertility is poor, so the green onions planted on sandy loam are white, rough and loose, and the layers of outer dry film are not crisp and tender, spicy and spicy, and not resistant to storage and transportation. The green onions planted in clay loam are white and crisp, and the tissue is also dense and sturdy. Due to the poor ventilation of the soil, it is not conducive to the root development of green onions, which can easily lead to delicate plants, white and slender onions and low yield.

In order to obtain high quality and high yield, Welsh onion should choose loose and granular dark brown clayey loam, and also choose the land with deep tillage layer, rich organic matter and strong fertility and water retention.

As the main edible green onion is white, soil cultivation can soften the leaf sheath, prevent lodging, and improve the yield and quality of green onion, so soil cultivation is also very important in the process of planting green onion.

Generally speaking, the higher the soil is, the longer the onion is white, and the green onion tissue is also more abundant and white. when the green onion enters the vigorous growth period, with the lengthening of the leaf sheath, it is necessary to cultivate the inter-row ridge soil into the green onion furrow in time through inter-row ploughing and step-by-step cultivation of the soil, so as to change the ridge furrow into ridge back.

The height of each cultivation should be determined according to the growth height of the pseudostem, and the soil should be cultivated to the boundary between the leaf sheath and the leaf body, and only the leaf sheath should be buried, not the leaf body, so as to avoid leaf decay. It is generally necessary to cultivate the soil for 3 or 4 times from the Beginning of Autumn to the harvest. When cultivating the soil, we should pay attention not to hurt the roots of green onions, pat the soil on both sides of the ridge, and prevent the collapse caused by Rain Water scouring and watering. Soil cultivation should be carried out when the soil moisture is appropriate. It is not easy to operate when it is dry, and it is easy to cause mud and soil hardening if it is too wet.
