1978到1979年在Virginia对Va—72R品种进行了一项田间施肥试验,方法有基施;或叶片喷施N、K、Ca、Mg、P、Mn、Zn、Fe、B、S或C1;或各种元素的混合施肥。以研究花生小核盘菌腐烂病发病密度。在荚果发育期间,多次叶片喷施Zn或Cu对小核盘菌腐烂病有相当的抑制作用。1978年4次叶片喷施ZnSO_4,cuSO_4或Nutra—Phos ZMC(包括Zn、Mn、Cu、P、Ca和S),每公顷荚果产量分别为3.55、2.56和3.03吨,叶施Nutra—Phos3—15(Zn、Mn、P、Ca和S)和基施镁石灰或石膏较对照也增加了产量。1979年大部分处理降低了小核盘菌发病率,但增产不明显。
A field fertilization experiment was conducted on Va-72R cultivars from 1978 to 1979 in Virginia with either basal application or foliar application of N, K, Ca, Mg, P, Mn, Zn, Fe, B, S or Cl; Or various elements of the mixed fertilization. In order to study the incidence of rotten pests Sclerotinia perenne disease density. During the development of pods, Zn or Cu spraying on leaves for many times had a considerable inhibitory effect on the rot of S. sclerotiorum. In 1978, the yield of pod per hectare was 3.55, 2.56 and 3.03 tons, and Nutra-Phos3-15 was applied to foliar spray ZnSO4, cuSO4 or Nutra-Phos ZMC (including Zn, Mn, Cu, P, Ca and S) (Zn, Mn, P, Ca and S) and base magnesia lime or gypsum also increased the yield compared to the control. Most treatments in 1979 reduced the incidence of Pneumococcus, but the yield was not significant.
