Fertilizer can provide nutrients for fruit tree growth, organic manure can not only providenutrients for fruit trees, but also improve fruit quality, reduce crop pesticide residue. So weharvest fruit with good quality and appearance, high yield. This experiment was setrespectively in the Shaanxi province Luochuan northwest A&F university apple stationorchard and in the Luochuan southwest village orchard from November2012to November2013. Fuji (Malus domestica Borkh, CV Fuji) which had been achieved high yield as testmaterials. Respectively to study the application of controlled release fertilizer in Fuji appleorchard, set meals, there are7kinds of goods of organic compound fertilizer and fertilizereffect, but also on the fertilizer demonstration research. The main results were as follows:1. The application of formula fertilizer increase significantly blade. We found no significantdifference between controlled release fertilizer and contrast. The application of formulafertilizer and controlled release fertilizer had significant difference on the leaf netphotosynthetic rate. The application of formula fertilizer fruit size increased, yield per plantand area yield increased by10.9%, which reached significant difference. The application ofcontrolled release increased fertilizer fruit weight and yield to a certain degree. Comparedwith control, the application of formula fertilizer increased fruit hardness, soluble solids by8.5%and6.7%respectively. Total acid amount reduced. Controlled release fertilizer wasapplied increased fruit hardness, which also improved the content of soluble solids. Total acidascent obviously.In terms of fruit color, there were no obvious difference.2. We found that the application of controlled release fertilizer can increase significantly theratio of good apple fruit,80and above level fruit ratio is big, each㎏apple wholesale priceis0.25yuan, higher than general chemical fertilizer applied. Economic benefit of per acreincreased more than the average by9.3%, net income increased by15.06%.3. The use of refined organic fertilizer had the optimal performance in the aspects of crownbreadth, trunk girth, fruit growth, so it was suitable for potential weak tree shape index andper acre yield of wood the earth application is higher, followed by the application ofsuperconducting smart organic fertilizer, refined organic fertilizer, Qin--Geng ecologicalorganic fertilizer. In terms of the inner quality of fruit, wood the earth applied with a high content of fruit soluble solids, acidity, followed by the application of superconducting smartorganic fertilizer. Fruit hardness is best under the application of Qin--Geng ecological organic.Compared with other several kinds of organic compound fertilizer, the tinctorial yield is betterwith the application of wood, superconducting smart refined organic fertilizer, organicfertilizer. To sum up, the application of wood the earth organic fertilizer has a betterperformance on commercial and yeild; Other organic fertilizer fertilization effect also havetheir own advantages. So they all can be used in production.
