摘要
开展生姜田间施用养分构成与姜腐烂病防治试验,结果表明:生姜在中等土壤肥力水平,栽植密度83 333穴/hm2(穴距35.3 cm,行距34.0 cm)下,施用有机肥料30～50 t/hm2,配合施纯N 200～300 kg/hm2、P2O5 100～150 kg/hm2、K2O 150～500 kg/hm2,比例为1∶0.3～0.7∶0.5～1.7,植株抗性较好,群体生长势较强,可获得30～35 t/hm2的较高产量。用生物农药青萎散处理姜种和土壤,可提高抗病性,减少姜腐烂病发病率,增产17.1%～24.9%。
Field experiment on nutrient composition and rot disease control of ginger were launched,the results showed that ginger in soils of medium fertility levels,when plantation density was 83 333 cave per hectare（cave spacing 35.3 cm,row spacing 34.0 cm）,employed organic fertilizer 30～50 t/hm2,added pure nitrogen 200～300 kg/hm2,P2O5 100～150 kg/hm2 and K2O 150～500 kg/hm2,with the ratio of 1∶0.3～0.7∶0.5～1.7,individual plant had good resistance,groups had strong growth potential,the high yield of 30～35 t/hm2 was got.Used Qingweisan to manage ginger seeds and soil,the disease resistance increased,the incidence of rot in ginger reduced,the rate of growth was from 17.1% to 24.9%.
