花桥村位于长沙县东部,三面环山,一面临江,气候温和,土质良好,适于种植水稻。该村地形较为复杂,有冲田、塅田、高岸田和易涝田,耕作制度为双季稻——绿肥及双季稻——油菜,常年种植双季稻面积约1300亩。历来危害水稻的主要害虫有稻飞虱(褐稻虱和白背飞虱),稻黑尾叶蝉、稻纵卷叶螟、二化螟;次要害虫有稻蓟马、稻象虫甲、稻白翅叶蝉等。危害水稻的主要病害有稻纹枯病、稻瘟病和白叶枯病。过上防治水稻病虫害主要依靠化学农药,1979年全村平均每亩农药费用为5.91元,个别小组高达12.37元。1980年起,洲南农学院植保研究室生态组与长沙县植保站合作,在农牧渔业部和省农业厅的帮助下,在该村开展稻田生态系统病虫综合治理的实践,几年来取得了较显著的成绩,现将情况报道如
Huaqiao Village is located in the eastern part of Changsha County, surrounded by mountains on three sides, facing Linjiang, a mild climate, good soil, suitable for planting rice. The village topography is more complex, with Okita, 塅 Tian, Gao Shantian and easy field, tillage system for double cropping rice - green manure and double cropping rice - rapeseed, perennial planted double cropping rice about 1300 acres of area. The main pests that have endangered rice are planthopper (brown planthopper and white-backed planthopper), rice leafhopper, leaf roller and rice stem borer, secondary insects such as rice thrips, Rice white wing leafhopper and so on. Major diseases endangering rice are rice sheath blight, rice blast and bacterial leaf blight. Over prevention and control of rice pests and diseases mainly rely on chemical pesticides, the village in 1979 the average cost per acre of 5.91 yuan of pesticides, individual groups up to 12.37 yuan. Since 1980, the Ecological Group of Plant Protection Research Office of Chanan South Agricultural University has cooperated with Plant Protection Station of Changsha County. With the help of Ministry of Agriculture, Animal Husbandry and Fisheries and Provincial Department of Agriculture, the practice of comprehensive management of pests and diseases of paddy field ecosystem has been carried out in this village. The more significant achievements, the situation is reported
