A kind of correction method of citrus boron poisoning

Abstract

The invention discloses a correction method for citrus boron poisoning, which adopts a preparation for the underground part and a preparation for the above-ground part; the preparation for the underground part is 15% copper ammonia and algal seaweed fertilizer; the preparation for the above-ground part is 25% pyrazole Ayresstrobin, amino acid calcium, and sodium nitrophenolate; the corrective method is: after the diagnosis of citrus boron poisoning, spray the crown of the tree 4 times on the ground part according to the reagent ratio, once a month, and the leaves must be sprayed thoroughly each time; at the same time, The underground part is irrigated 3 times according to the reagent ratio, once every 20 days or so, and the ratio solution is 10-15kg each time. After the diagnosis of citrus tree boron poisoning, adopt the optimal ratio of the present invention, the yellowing area of ​​citrus tree leaves will not expand, the leaves will not fall off, and the new shoots drawn out after 2 months will be normal, and the leaves and soil will be normal within 6 months The effective boron value is normal, and the impact on the yield of the tree in the current year is relatively small; at the same time, the technology adopted in the invention has strong practical operability, quick effect, and low cost to solve the boron poisoning of citrus.
