文安县地处黑龙港流域,素有大洼之称,杂草不繁自茂。全县有各种果树24000亩,其中80%以上的果园由于中耕除草不及时造成草荒,严重影响着树势发育,并助长了病虫害的发生和蔓延。同时因土壤有机质含量低,有机肥料不足,降低了化学肥料的施用效果。因此,使一些开始进入结果期的果树树体衰弱,生理病害相继发生。如城关镇西光州,三村,四村,西关等近四百亩果园,由于树体长期得不到恢复,不少苹果,梨和桃树出现枯枝死树现象,树体处于极度不良状态,导致果品产量低,质量差。如何尽快恢复和保持树势,
Wen’an County is located in the Heilongjiang River Basin, known as the Dawa, weeds are not complicated. The county has a variety of 24000 acres of fruit trees, of which more than 80% of the orchards as a result of cultivation and weeding caused by grass shortage, seriously affecting the development of tree vigor, and contributed to the occurrence and spread of pests. At the same time due to the low content of organic matter in the soil, lack of organic fertilizer, reducing the application of chemical fertilizers. Therefore, some fruit trees that started to enter the fruiting period are weakened and physiological diseases occur one after the other. Such as the Chengguan Town Xiguangzhou, three villages, four villages, such as the West Gate, nearly four hundred acres of orchards, as the tree can not be long-term recovery, many apple, pear and peach dead tree phenomenon appears dead trees in extremely poor condition, Lead to low fruit yield and poor quality. How to restore and maintain the tree vigor as soon as possible,
