摘要
试验研究了中低产田花生喷施多效唑对花生生长发育、产量和品质的影响。结果表明，花生初花后25～35d叶面喷施多效唑，可明显抑制主茎和侧枝的生长，促进干物质向荚果分配，增加库容量，提高库、源比，使单株结果数及产量增加，从而提高花生单位面积产量。但易造成花生病害加重，百果重、百仁重和出仁率降低，籽仁脂肪和蛋白质含量下降。因此，在花生中低产田使用多效唑必须与病害防治相结合，才能实现花生高产优质。
The effect of paclobutrazol sprayed on growth, development, yield and quality of peanut were studied under middle and low yield. The result showed that by application of paclobutrazol the plant stem height and twig length of peanut were reduced, the dry matter of pods, the economic index, the sink size and the sink/source were increased, the number of pod per plant and the pod weight per plant were also increased, Thus the yield was greatly improved. With paclobutrazol spraying, the disease of peanut was more serious, 100-pod weight, 100-kernel weight, the ratio of shelled peanut oil content and protein content were decreased. In the cultivation of peanut under middle and low yield, the yield and quality of peanut could be improved through spraying paclobutrazol combination with guarding against disease.
