1986年微肥多点试验结果表明,在微素缺乏的土壤上施硼、锌、钼肥均有一定肥效。花生在黄泥及黄沙泥上施微肥主要增加荚果数及饱满度;单施钼增产5.61%,单施锌增产2.8%,单施硼增产3.7%。大豆在大、小灰黄泥上施微肥主要增加单株荚果数和荚粒数;单施钼增产8%单施锌增产6%,单施硼增产4%。玉米在大灰黄泥上单施锌增产5%,单施钼增产2%,单施硼几乎无效。水稻在中等肥力的白胶泥田上施微肥主要增加穗实粒数和千粒重;单施锌增产11.3%单施钼增产9.1%,单施硼增产1.1%。西瓜在上等肥力的黄红油沙土上施微肥不增产,在胶泥田上平均增产3.3%,在中等肥力的潮泥田上平均增产7.7%。 The results of multi-point test of trace fertilizer in 1986 showed that applying boron, zinc and molybdenum fertilizers on the micronutrient deficient soil all had certain fertilizer effect. Peanut fertilizer on yellow mud and yellow sand mainly increased the number of pods and plumpness; the single application of molybdenum increased 5.61%, the single applied zinc increased 2.8% and the single applied boron increased 3.7%. Soybean fertilizer on large and small ash yellow mud increased the number of pods per plant and the number of pods; single application of molybdenum increased yield of 8% of single application of zinc increased yield of 6%, single application of boron yield 4%. Corn on the gray cement on a single application of zinc increased by 5%, only 2% increase in molybdenum yield, boron alone almost ineffective. Rice fertilization in moderately fertile white clay paddy increased the number of grains per spike and the grain weight per 1000 grains; the yield of single zinc increased 11.3% and that of molybdenum increased 9.1% and that of boron alone 1.1%. Watermelon on the top fertility of Huangyou oil sand does not increase the yield of fertilizers, an average increase of 3.3% in the plastic clay fields, tidal muds in medium fertility average yield of 7.7%.
