| 中文摘要: |
| 黄土高原南部旱作区,田间试验不同化学及营养调控措施对小麦生长发育及产量的影响。结果表明,施氮可以明显促进小麦分蘖,使用植物生长调节剂及其与微量元素(MnSO4)配合对小麦分蘖有促进,其中以多效唑及其与MnSO4配合处理较为突出;多效唑处理降低了小麦株高。植物生长调节剂及其与MnSO4配合增加了小麦叶面积和叶片的SPAD值,其中多效唑+MnSO4+甜菜碱处理的叶面积及SPAD值的增加尤为突出。采用多效唑、MnSO4和甜菜碱以及多效唑和MnSO4配合显著提高了小麦产量,较清水对照产量分别提高了1 014.7 kg/hm2和640.5 kg/hm2。说明不同的化学及营养调控措施可以有效地调节小麦生长,提高作物产量。 |
| 英文摘要: |
| A field experiment was used to study the effects of plant growth regulators and manganese sulfate on the growth and development and grain yield of winter wheat．The result showed that the treatment of MnSO4 and nitrogen fertilizer increased the number of tillers per plant and the treatments with paclobutrazol addition decreased the height of winter wheat．The treatments of different combinations of the plant growth regulators and MnSO4 nutrient increased the areas of leaf and the content of chlorophyll （SPAD value） in leaves the effect of the treatment of PP333（paclobutrazol）＋ MnSO4＋Gb （glycine betaine） was more significant than other treatments．Compared to the treatment with water soaking treatment the treatments of PP333＋MnSO4＋ Gb and PP333＋MnSO4 also increased the grain yield of wheat by 1 014．7kg／hm2 and 640．5kg／hm2 respectively． It is concluded that the plant growth regulators and nutrients could improve the yield of winter wheat． |
