韭菜干尖是保护地韭菜常见的病害,不仅影响韭菜产量,而且降低了韭菜品质,危害十分严重。分析韭菜干尖主要是由以下几种原因造成的。1、施肥过多。中性土壤条件适宜韭菜的生长发育,土壤中如果施入过量的人粪尿等酸性肥料,会使土壤酸化,导致干尖。经常性的过量施用化肥,也会造成土壤溶液浓度过大,造成干尖,施入的大粪干如果未经充分腐熟,会放出大量氨气,酸性土壤中会放出大量二氧化氮气体、这些毒气都会使韭菜发生干尖现
Leek tip is a common disease protection leeks, not only affect the yield of leeks, but also reduce the quality of chives, the harm is very serious. Analysis leek tip is mainly caused by the following reasons. 1, excessive fertilization. Neutral soil conditions suitable for the growth of leeks, soil, if applied to excessive human excrement and other acidic fertilizers, will soil acidification, leading to dry tip. Frequent over-fertilization of fertilizers can also result in excessive concentrations of soil solution, resulting in dry tips. Large amounts of manure applied to the soil can release large amounts of ammonia gas if not adequately decomposed, and produce large amounts of nitrogen dioxide gas in acid soils Leek will make dry tip now
