Vegetables need a lot of nitrogen and potassium, phosphorus demand is less, such as the ratio of nitrogen and phosphorus potassium required for eggplant is 3:1:4, cucumber is 3:1:10, tomato is 6:1:12. In greenhouses, diammonium phosphate should not be applied in a large amount, and it must not be mixed with alkaline fertilizers such as grass ash to prevent the generation of ammonia and ammonia damage. ?
The carbon-nitrogen ratio of cakes is small, and the decomposition is fast. Locally, high temperature and high concentration of ammonia and organic acids are easy to generate. It is easy to burn roots and it is not suitable for multiple applications.
In the later stage of vegetable growth, topdressing of potassium fertilizer is used. Vegetables generally require more potassium before and after flowering, and then gradually decrease. Do not apply more zinc, zinc deficiency when spraying foliar spray of 0.05% to 0.2% of zinc sulfate solution.
Chloride ions can reduce the starch and sugar content of vegetables, and reduce the yield of vegetables, and can lead to soil acidification, decalcification, causing soil compaction, and it is not appropriate to use chlorine-containing fertilizers in vegetable greenhouses. ?
Phosphate fertilizers are suitable for basal fertilizer or concentrated in the root-dense soil layer in the early stage of vegetables. It is not appropriate to disperse phosphate fertilizers in vegetable greenhouses.
When the greenhouse is fertilized when it is dry, not only can the fertilizer effect not be fully exerted, but also it is easy to burn roots. Fertilization should be conducted in the trenches, and the fertilizer should be buried afterwards, or the fertilizer should be applied along the water. ?
Do not apply Rare Earth Fertilizer directly to soil in vegetable greenhouses in winter. Can be used 0.05% ~ 0.07% of rare earth fertilizer solution sprayed on the leaves of vegetables, spraying 50 to 60 kg per mu solution. ?
Iron fertilizers should not be applied to the soil because iron is easily converted into insoluble compounds by the soil and loses its fertility. Iron is not easy to flow on the leaves and should be sprayed on the leaves. It can be sprayed on the leaves of vegetables with a 0.1% to 0.3% ferrous sulfate solution.
