Vegetables are generally short-term nutritional crops, which can be re-broadcast. Due to the short growth period, the nutrients absorbed per unit time are much more than the crops with longer growth period and higher yield. Therefore, more quick-acting fertilizer should be applied during cultivation. Generally, the roots are deep and wide, the roots are more, and the root hairs can absorb more nutrients, and the fertilization can be more extensive. The vegetables with poor root development, shallow distribution, and poor nutrient absorption should be fertilized finely.
Different vegetables need to adopt different fertilization techniques and methods.
Leafy vegetables: Leafy vegetables mainly include cabbage, green vegetables, spinach, and leeks. Leafy topdressing is mainly based on nitrogen fertilizer, but at the same time of application of nitrogen fertilizer, it is necessary to increase the application of phosphorus and potassium fertilizer. For example, cultivation of Chinese cabbage, the two fertilizations before entering the rosette period and before the core are the key to high yield. If the supply of nitrogen fertilizer during the growing period is insufficient, the plants are short and the tissues are rough. Leafy vegetables cultivated in spring are also easy to twitch early; if the phosphorus and potassium fertilizers in the late stage of the ball-like leaves are insufficient, it is often difficult to form a ball.
Fruits and vegetables: Fruits and vegetables include melons, solanaceous fruits and beans. In general, the amount of nitrogen fertilizer required for seedlings is high, but excessive application of nitrogen fertilizer tends to cause long growth, but the flowering result is prolonged, resulting in falling flowers and fruits. When entering the reproductive growth period, the amount of phosphate fertilizer needs to increase sharply, and the amount of nitrogen fertilizer needed to be slightly reduced. Therefore, phosphorus and potassium fertilizers should be added. , control the amount of nitrogen fertilizer. After the cucumber is placed on the melon, it should be re-fertilized. Each batch of melon should be supplemented with a fertilizer.
Root vegetables: root vegetables mainly include radishes, carrots, etc., and the edible part is fleshy root. In the early stage of root vegetables, more nitrogen fertilizer should be applied to promote the formation of hypertrophic green leaves. Potassium fertilizer should be applied in the middle and late growth stages, and the amount of nitrogen fertilizer should be properly controlled to promote the transport of assimilated materials into the roots in order to form strong fleshy roots. If in the late growth stage of root vegetables, there is too much nitrogen fertilizer and insufficient potassium fertilizer, it is easy to make the aboveground part grow, the rhizome is small, the yield is decreased, and the quality is deteriorated.
