Question: Several vegetable greenhouses are grown with tomatoes, and 100 kg of organic-inorganic compound fertilizer is used as the base fertilizer per acre. Why do some greenhouses look good after transplanting, and some have always been seedling yellow? A: Organic-inorganic compound fertilizers have a low content of chemical fertilizers and are still a kind of fertilizer mainly composed of organic fertilizers, so the fertilizer effect is slow. Only organic-inorganic compound fertilizers are used as basal fertilizers. In greenhouses with high fertility, the impact on transplanting seedlings is not significant, but in greenhouses with low fertility, transplanting seedlings will be yellow due to insufficient supply of nitrogen. Therefore, when organic-inorganic compound fertilizers are used as base fertilizers, suitable amounts of fast-acting fertilizers should be used.
