Fruit vegetables: edible parts are reproductive organs. Generally, vegetables and vegetables need more nitrogenous fertilizer at the seedling stage, but excessive application of nitrogenous fertilizers may lead to leggy, but delay the flowering result, resulting in falling fruit and fruit. In the reproductive growth period, the amount of phosphate fertilizer needs to increase rapidly, and the amount of nitrogen fertilizer needs to decrease slightly. Phosphorus and potash fertilizers were used to control the amount of nitrogen fertilizer. Root vegetables: The edible portion is a fleshy root. In the early growth stage of root vegetables, more nitrogen fertilizer is needed to promote the formation of hypertrophic green leaves; in the middle and later stages of growth (in the root growth stage of the fleshy root), more potassium fertilizer should be applied, and the amount of nitrogen fertilizer should be properly controlled so that the assimilation material of the leaves can be transported to the roots to form larger ones. Fleshy roots. If the application of nitrogen fertilizer is too late in the growth period of root vegetables, and the application of potassium fertilizer is insufficient, the above-ground part is easy to grow, the fleshy root is small, the yield is decreased, and the quality is deteriorated. Shed room vegetables: greenhouse vegetables should be applied more organic fertilizer. Because vegetables in greenhouses have a much larger amount of fertilizer per unit area than exposed vegetables, and no rainwater is leached, most of the remaining fertilizer remains in the soil, making the concentration of soil nutrients in the soil too high, which prevents roots from absorbing nutrients. Therefore, in the cultivation of greenhouse vegetables should fully consider the after-effect of the former wolfberry fertilizer, apply more organic fertilizer, appropriate less fertilizer, to avoid the accumulation of salt and make leeks vegetables.
