注意增加有机肥和生物菌肥用量。有的菜农肥料投入越来越多,产量却越来越低,这与其不合理的施肥习惯有关。主要表现在长期过量施用化肥,忽视施用有机肥,连年种植不深翻土壤,盐分大量积累在浅层耕作层。因此,在蔬菜定植前,要注意增加有机肥用量,深施有机肥。其目的是为了增加土壤中有机质含量,促进土壤团粒结构形成,增加土壤透气性。此外,还要注意增加生物菌肥用量。生物菌肥能够增加土壤中有益微生物数量,抑制土传病害发生,同时还可促进
Pay attention to increase the amount of organic fertilizer and biological fertilizer. Some vegetable farmers fertilizer more and more inputs, production is getting lower and lower, with its irrational fertilization habits. Mainly in the long-term over-fertilization of fertilizer, neglect the application of organic fertilizer, successive years planted deep soil, salt accumulation in shallow tillage. Therefore, before planting vegetables, pay attention to increasing the amount of organic fertilizer, deep application of organic fertilizer. Its purpose is to increase soil organic matter content, promote the formation of soil aggregate structure, increase soil permeability. In addition, but also pay attention to increasing the amount of biological fertilizer. Biological fertilizer can increase the amount of beneficial microorganisms in the soil, inhibit the occurrence of soil-borne diseases, but also can promote
