我是永寿县上邑乡北顺什村三组村民赵产量,家有6亩苹果园。这些年来由于施肥单一,经济效益一直很差,果树长势不好,根腐、腐烂病一年比一年多。结的果子个小,果面不净,大多是劣质果,徒劳没效益、投资无效益。我已心灰意冷,想挖了果树改种其他粮食作物。 I am a village in Yongshou County, Shangyi Township, North Shun Village, three groups of Zhao yield, home has 6 acres of apple orchards. In recent years, due to a single fertilizer, the economic benefits have been poor, fruit trees grow well, root rot, decay disease year after year. Results of a small fruit, fruit is not net, mostly poor quality fruit, no useless, inefficient investment. I have been disheartened, would like to dug fruit trees to switch to other food crops.
