| According to extrusive problem in the production of apple The research on the key technologies and cultivation pattern of high quality apple production in Shaanxi Province Luochuan County from 2005 to 2007 showed that1) the four center technologies of"changes appearance greatly, strongly pulls, applies fertilizer skillfully, free-pollution"are key measure of enhancing apple high quality and conforming to the apple industry development need.2) changes appearance is crucial technical measure of improving the apple quality, may improve obviously ventilates the diaphanous condition, distribute rationally tree body nutrition, promote the brachyblaste form, increas obviously tree body resistance and the apple output, quality and the economic efficiency.3) strong pulls to be able to promote the seed, in the victory bare increase the brachyblaste proportional control tree condition to increase flowers, is advantageous in the output enhancement, also a same coarseness average bears fruit along with is open for business the angle to increase increases.4) increases executes the farm manure to be possible to enhance the soil ulmin obviously, the fast-acting nutrient content, after specially tests moors the fat tree body growth to be vigorous and healthy, exuberant, the leaf blade quality is good, executes the farm manure the orchard to compare non-farm manure the orchard Chinese acre to save 56.3 Yuan, the Chinese acre additionally receives 1279.3 Yuan, also the apple selling price outdoes 0.17 Yuan/kilogram.5) through changes appearance reasonably the trim and the employment moors fat, necessary implements physics, the biological method may strengthen the tree body resistance, reduces plant disease the occurrence, thus achieves without the environmental damage and the green standard.6) the ecology cultivation pattern could enhance soil fertility effectively, improve soil environment, reduced the orchard production cost and chemical fertilizer to the orchard pollution.
