肥料品种的选择温室栽培蔬菜,在肥料选择上,除选氮磷钾复合肥、磷酸二铵、尿素、碳铵、硫酸钾、冲施肥等种类外,还要积极选用蔬菜专用复合肥、有机无机复合肥。为增强作物根际有益微生物的活动,改善土壤理化性状,调节作物营养平衡,推荐使用氨基酸、腐植酸类冲施肥、生物有机复合肥及微生物肥等辅助性肥料,如根瘤菌肥、固氮菌肥、磷细菌肥、硅酸盐细菌肥、复合微生物肥等。同时,提倡使用添加硝化抑制剂的缓控肥料,防止化肥的淋失、挥发损失。提醒农户忌用含氯肥料(如氯化铵)或硝态氮肥(如硝铵)。
The choice of fertilizer varieties Greenhouse cultivation of vegetables, in the fertilizer selection, in addition to the election NPK fertilizer, diammonium phosphate, urea, ammonium bicarbonate, potassium sulfate, fertilization and other types of fertilizers, but also actively choose vegetable-specific compound fertilizer, organic and inorganic Compound fertilizer. In order to enhance the activities of beneficial microorganisms in rhizosphere soil, improve soil physical and chemical properties and adjust crop nutrition balance, it is recommended to use auxiliaries such as amino acid, humic acid type fertilizers, bio-organic compound fertilizer and microbial fertilizer, such as rhizobium, , Phosphorus bacterial fertilizer, silicate bacterial fertilizer, compound microbial fertilizer. At the same time, to promote the use of nitrification inhibitors to slow the controlled fertilizer to prevent leaching fertilizer, volatile loss. Remind farmers avoid the use of chlorine-containing fertilizers (such as ammonium chloride) or nitrate nitrogen fertilizer (such as ammonium nitrate).
