要种出优质无公害水果,施肥要讲究。一是不能过量施肥。防止树体徒长,果实品质降低,要培养中庸树势。树势衰弱时,要及时补肥。二是不能偏施氮肥,要多种元素配合,尤其注意微量元素的供应,防止树体缺素症。三是要多施农家肥、有机复合肥、微生物肥料、腐殖酸类肥料。目前农家肥有人粪尿、厩肥、堆肥、饼肥、绿肥、沼气肥以及用作物茎秆沤制的肥等。有机复合肥有阿姆斯生物肥、超大生物有机肥、绿洲植物营养液、正丰生态有机肥等。微生物肥料有根瘤菌、固氮菌、磷细菌、复合菌、硅酸盐细菌等。微生物肥料有肥力高、禾施丰、高效有机菌肥等。腐殖酸类或核酸类营养型肥料有高美施、开特灵等。将这些肥料有选择地用于基肥、追肥或根外施肥,很有效。
To plant high-quality pollution-free fruits, fertilization should pay attention. One can not over fertilization. Prevent the body tree-length, fruit quality is reduced, to cultivate the golden tree. When the tree is in weak condition, it is necessary to make up fertilizer in time. Second, we can not bias nitrogen fertilizer, with a variety of elements, with particular attention to the supply of trace elements to prevent tree deficiency. The third is to apply more manure, organic fertilizer, microbial fertilizer, humic acid fertilizer. At present, manure is excreted by manure, manure, compost, pie, green manure, biogas fertilizer and crop stalks. Organic fertilizer with Armstrong fertilizer, large organic fertilizer, oasis plant nutrient solution, is abundance of ecological organic fertilizer. Microbial fertilizer Rhizobium, Azotobacter, phosphorus bacteria, complex bacteria, silicate bacteria. Microbial fertilizer has high fertility, Wo Shi Feng, efficient organic fertilizer and so on. Humic acids or nucleic acids Nutrient type fertilizers are high Meisen, Kaitelun and so on. It is effective to use these fertilizers selectively for basal, topdressing or root fertilization.
