摘要
运用农业立体污染防治的新观念,对沙田柚生产中的立体污染问题进行了分析。沙田柚生产中大量不合理使用农药、化肥和烂果、残枝的随意处置以及大气环境污染等所造成的农业系统中水体-土壤-生物-大气立体交叉的污染即"农业立体污染",已影响到农业生态安全、环境健康,造成沙田柚产品质量下降,不符合绿色食品的要求,严重阻碍了沙田柚优质高效产业化的发展。并对人、畜健康构成潜在性危害。防治沙田柚果园立体污染的基本对策是:建立和完善果园环境质量监控体系,大力推广沙田柚病虫害综合防治技术和科学施肥管理,积极搞好农业防治。
This paper analyzed the tri - dimensional pollution in the shaddock production based on the new concept of tri - dimensional pollution. In the production of shaddoek, tri - dimensional pollution refers to the overall pollution of the water body - soil - organism - atmosphere system caused by abundant unreasonable application of pesticides, chemical fertilizers and improper disposal rotten fruits and bad branches along with the atmosphere environmental pollution. Tri -dimensional pollution has seriously affected the ecological security, environmental health and declining of shaddock fruit quality, which is not in conformity to the requirements of green food and ultimately impede the quality and efficient industrial production of shaddock and place potential hazards to human health. The essential countermeasures to control the tri - dimensional pollution is to establish and improve orchard environmental quality monitor system, and to carry out widely integrated pest control technologies and agricultural prevention measures combined with scientific fertilizer application and management.
