| 摘 要： | 采用不同浓度的多效唑控制橘园的主要杂草,以探索对橘园杂草高度与密度有效控制的途径。结果表明:在试验剂量900～1800g/hm2范围内,多效唑对禾本科杂草的生长抑制作用随处理剂量的加大而增强,以1350g/hm2剂量的多效唑处理效果最为理想。3种剂量的多效唑处理均对禾本科杂草的分蘖具有强烈的促进作用,使田间杂草密度大大增加;对2种阔叶杂草——一年蓬和觅菜的生长表现出强烈的抑制作用,但未达到理想的控制高度。

| Abstract: | The experiment tried to find the effective methods of controlling the vital weeds' height and density with different concentrations of PPP333 in orange orchard. The results showed that:In the PPP333 dose range 900 ～1 800 g/hm2,the growth of the grass was inhibited with the increasing of PPP333. The ideal treatment of PPP333 was 1 350 g/hm2. The three doses of PPP333 were all with a strong role in promoting the tillering of grass weeds,so that weed density increased greatly. The results of two kinds of broad-leaved weeds——Erigeron annuus(L.)Pers and Amaranth also showed a strong inhibitory effect,but the tests did not achieve the desired control height. |
