硼酸(或硼砂)作为肥料(微肥)可以解决小麦、棉花、油菜等作物的不稔、蕾而不花或花而不实的问题,提高结实率,增加产量。近年来研究发现,硼肥还可以作为农药来使用,防治作物病害。水稻施用硼肥对纹枯病的防治效果和增产率分别为80%和13.3%。此外,油菜的“萎缩病”、萝卜的“水心病”、甜菜的“心腐病”、芹菜的“裂茎病”、烟草的“顶腐病”、苹果的“内木栓病”和“干斑病”等都可以用硼肥来防治。方法是:用硼酸或硼砂0.05—0.2%的水溶液喷洒。叶面喷硼的利用率是
Boric acid (or borax) as a fertilizer (micronutrient) can solve the problem of non-blooming, buds and other crops of crops such as wheat, cotton and rape, improving seed setting rate and increasing yield. In recent years, the study found that boron can also be used as a pesticide to prevent crop diseases. The control effect and yield increase of rice boron on rice sheath blight were 80% and 13.3% respectively. In addition, the rape’s “atrophy disease”, the radish’s “water heart disease”, the beet’s “heart rot”, the celery’s “crack stem disease”, the tobacco’s “top rot” Apple’s “cork disease” and “dry spot disease” and so can use boron to control. The method is: spraying with boric acid or borax 0.05-0.2% aqueous solution. Foliar boron utilization is
