【摘要】 旱(薄)地条件下,研究了叶面喷施硼肥和钼肥对春播和夏播花生生长发育及产量的影响。结果表明:无论春播还是夏播,施肥处理的多数农艺性状明显好于对照,但不同施肥处理间存在较大差异,其中硼钼肥配施对花生营养性状的促进作用优于单施钼肥或硼肥,春、夏播结果一致;单施硼肥有利于提高春花生单株结荚数,单施钼肥有利于饱果率,硼钼配施有利于同时提高单株结荚数和饱果率;硼钼配施或单施硼肥有利于提高夏花生双仁果率,单施钼肥对提高夏花生产量性状无明显影响;春、夏播4个施肥处理产量,以硼钼配施的处理最高,比对照平均增产12.0%,其次为单施硼肥,比对照平均增产7.0%,单施钼肥春播增产5.6%,夏播无明显增产作用。因此,生产中应注意硼钼肥配施。更多还原

【Abstract】 Under the condition of dryland or leanness soil,effects of foliar-spraying of boron fertilizer and molybdenum fertilizer on growth and development and yield of peanut sown in spring and in summer were studied.The results showed that main agronomic characteristics of peanut sown in spring and in summer under fertilizer treatment were better than CK,and there were significant differences among different fertilizer treatments.Furthermore,a combined application of boron and molybdenum fertilizer had more significant effect in improving the nutritional characteristics than single application of any kind of fertilizer.Single application of molybdenum fertilizer was helpful to increase the pod number.Single application of boron fertilizer could increase the pod number.Combined application of boron and molybdenum fertilizer or single application of boron fertilizer had favorable effect on improving double-kernel plump pod rate of peanut sown in summer,and single application of molybdenum fertilizer had no significant effect in yield characteristics.Compared with CK,the yield of peanut sown in spring and in summer was remarkably increased by 12.0% after combined application of boron and molybdenum fertilizer,and single application of boron fertilizer could increase the yield by 7.0%.Compared with CK,single application of molybdenum fertilizer could increase the yield of peanut sown in spring by 5.6%,whereas it had no visible effect on yield of peanut sown in summer.Therefore,combined application of boron and molybdenum fertilizer should be noted in peanut production.更多还原
