渭北优质无公害苹果生产技术研究

Organic Fresh Apple Production Techniques in Weibei Area

在渭北苹果产量大增，果品销售不畅的严峻形势下，研制出优质无公害苹果生产技术，其关键环节为：果园中以施有机肥和混合肥为主；严格疏花疏果；果实套袋；铺设反光膜；根据当地主要病虫害的发生规律，以农业防治和生物防治为主体，化学防治中以使用无公害农药为主，实现苹果的优质、高产、高效生产。

Under the serious situations of the increasing yield of apples and the decreasing sales volume in Weibei,weve found a new technique for organic fresh apple production.The main steps are:to apply organic fertilizer and mixed fertilizer to the orchard;to thin the flowers and fruits strictly;to wrap apples with bags;to lay reflex film.According to the rules that insects and diseases appear in these area,we chiefly undertake agricultural and biological prevention and cure,and use biorational insecticide in chemical prevention and control in order to produce apples in good quality and high yield.
