不同作业方式及药剂配方对黑龙江省半干旱区水田草害的防控效果

Control Effects of Different Operation Modes and Herbicide Formulas to Weeds in Semiarid Area of Heilongjiang Province

通过田间试验研究了不同作业方式及药剂配方对黑龙江省半干旱区水田草害的防控效果及对水稻产量的影响。结果显示,植保无人机作业区和人工喷雾机作业区水稻平均产量分别为589.45 kg/667 m^2和586.39 kg/667m^2,分别较对照增产4.64%和4.10%;使用配方1(80%苯·吡·西草净水分散粒剂+30%莎稗磷乳油)和配方2(2%双唑草腈颗粒剂+33%嗪吡嘧磺隆水分散粒剂)的处理水稻平均产量分别为585.28 kg/667 m^2和593.75 kg/667 m^2,分别较对照增产4.32%和4.32%。从杂草防控效果来看,植保无人机作业区和人工喷雾机作业区的防效提升率均值分别为68.61%和71.29%,使用配方1和配方2的处理防效提升率均值分别为26.04%和100.00%。

Field experiments were conducted to study the control effects of different operation modes and herbicide formulas to weeds and grain yield in semi-arid area of Heilongjiang province.The main results indicated as follows,in terms of rice yield,the average yields of plant protection UAV(unmanned aerial vehicle)operating area and artificial mist blower operating area were 589.45 kg/667 m^2 and 586.39 kg/667 m^2,increased by 4.64%and 4.10%respectively compared to CK.The average yields of rice with formula 1 and formula 2 were 585.28 kg/667 m^2 and 593.75 kg/667 m^2,increased by 4.32%and 4.32%respectively compared to CK.In terms of the weed control effects,the average control effects of plant protection UAV operating area and artificial mist blower operating area were increased by 68.61%and 71.29%,the average control effects of formula 1 and formula 2 were increased by 26.04%and 100.00%.
