0引言库尔勒香梨皮薄、肉细、味甜,品质极佳,深受消费者欢迎。沼液中有机酸的丁酸和植物激素中的赤霉素、吲哚乙酸及维生素B_(12)对病菌有明显的抑制作用,所以沼液被誉为无污染、无残毒、无抗药性的“生物农药”。在香梨生产中使用沼液是生产绿色无公害食品的需要,可减少化肥、农药投入,改善香梨品质。本试验旨在了解沼液在香梨上的使用效果,研究沼液在香梨上的施用技术,为大力推广沼液在香梨上的施用提供科学依据。1试验目的和意义沼液、沼渣是优质的有机肥料,而且沼液除富含氮、磷、钾等大
0 Introduction Korla sweet pear thin, thin, sweet, excellent quality, deeply welcomed by consumers. Biogas liquid organic acid butyrate and plant hormones in the gibberellin, indole acetic acid and vitamin B_ (12) on bacteria significantly inhibited, so biogas slurry is known as pollution-free, non-toxic, non-drug-resistant “Biological pesticide ”. Biogas slurry used in the production of pearls is the production of green pollution-free food needs, can reduce fertilizer, pesticide inputs, improve pear quality. The purpose of this experiment is to understand the effect of biogas slurry applied on fragrant pear, to study the application technology of biogas slurry on fragrant pear, and to provide a scientific basis for vigorously promoting the application of biogas slurry on fragrant pear. 1 Test Purposes and Significance Biogas slurry, biogas residue is a high-quality organic fertilizer, and biogas slurry is rich in nitrogen, phosphorus and potassium
