Premature drop of orange of item the year before last year is much, it is to have many reasons, among them main reason is the nutrient that establish system little, support the need of overmuch gains growth hard, below the condition that if abrupt water content lifts considerably in Ni earth,imposed again, root system is anoxic, tree body makes ego adjust, decrease to use up and appear a large number of premature drop.
Suggest you are in every 120 jins clear water, join 60 milliliter the ester inside element of liver mosses of Yun of farming abundant element and 1.5 grams 85% gibberellin crystal, rejoin 120 milliliter humic acid phosphoric acid of health treasure and 180 grams Bond head 2 hydrogen Potassium. Raise plant to be opposite with the ester inside element of liver mosses of Yun of farming abundant element of undesirable condition fight go against ability, leave the desquamation of the layer acerbity to undertake Jie is fought with gibberellin becomes fructification to fall off to building and be being formed, have complement quickly to cultivating body nutrient with fertilizer of face of blade and reduce premature drop.
If fructification surface covered brown copper scene, it is to become rusty to the spider is endangered and be caused. Proposal first gush breast of 1.8% A Weijun element are 3500 times oilier fluid, will lay eggs in order to exterminate undertake mite is given priority to be becominged progenitively (can prevent and cure at the same time other pest) , every other 20 days, respectively gush uses agent of in suspension of Qin of 20% 4 mite 1 times 1600 times fluid.
