田间小区试验结果表明 ,伴地农单用对春玉米田的藜、本氏蓼、反枝苋、龙葵等一年生阔叶杂草有良好防效。伴地农与乙草胺前后搭配使用或与莠去津、康施它混用可以扩大杀草谱 ,能够有效地防除玉米田的稗草、狗尾草、藜、本氏蓼、反枝苋、龙葵等一年生禾本科杂草和阔叶杂草 ,对禾本科杂草的综合株数防效为 5 0 %～ 94 % ,对阔叶杂草的综合株数防效为 86 %～ 10 0 %。适宜的混用组合和用量为 :伴地农与乙草胺前后搭配使用 ,乙草胺播后苗前土壤处理 375 0mL hm2 ,伴地农苗后茎叶处理 15 0 0mL hm2 ;苗后茎叶处理组合 ,伴地农 +莠去津 15 0 0 + 30 0 0mL hm2 或 12 0 0 +375 0mL hm2 ;伴地农 +康施它 90 0 + 180 0mL hm2 。茎叶处理适宜施药时期为玉米 2～ 3叶期 ,禾本科杂草 2～ 4叶期 ,阔叶杂草株高 3～ 5cm。在上述推荐剂量范围内对玉米安全
The field plot test results showed that the single-field peasants with field agronomy had good control effects on the annual broadleaf weeds such as quinoa, Polygonum orientale, Amaranthus retroflexus and Solanum nigrum in the spring corn fields. With the use of agrofumer and acetochlor before or after or with atrazine, Kang Shi it can be mixed to expand the spectrum to kill herbicide, can effectively control the corn field of barnyard grass, Setaria, Chenopodiaceton, Polygonatum, Amaranthus retroflexus, Solanum nigrum The annual grasses and broad-leaved weeds showed 50% to 94% of the combined number of weedy weeds and 86% -100% of the combined number of broad-leaved weeds. The suitable mix and dosage were as follows: with the use of agrobacterium and acetochlor before and after treatment, 375 0 mL hm2 of soil before sowing sowing acetochlor, and 1500 mL hm2 of post-emergence stem and leaf treatment of agroecosystem; Combination, with farmland + Atrazine 15 0 0 +30 0 0mL hm2 or 12 0 0 +375 0mL hm2; with agroforestry plus it Shi 90 0 +180 0mL hm2. Stem and leaf treatment suitable for maize 2 to 3 leaf stage, grass weeds 2 to 4 leaf stage, broad-leaved weeds height 3 ~ 5cm. Corn is safe within the above recommended dosage range
