不同量B、Zn肥对花生生长和产量的影响

EFFECTS OF DIFFERENT QUANTITY OF BORON AND ZINC ON GROWTH AND YIELD OF PEANUT

采用大田试验研究了增施不同量硼、锌微肥对花生生长发育和产量的影响,结果表明,在合理施用氮、磷、钾肥的基础上,适量配合施用硼、锌微肥可以明显促进花生一生的生长发育,增加花生第一对侧枝长、单株根瘤、叶片和荚果数等,显著提高花生产量,其中增施硼肥7.5和11.25 kg/hm2的处理比较对照分别增产6.87和8.19%,增施锌肥7.5和11.25 kg/hm2的处理比较对照分别增产7.17和5.20%。研究证明,在本试验大田条件下,以适量氮、磷、钾肥配施硼酸11.25 kg/hm2、硫酸锌7.5 kg/hm2较为适宜。

The experiment studied the effects of applying different amount of B and Zn to peanuts＇ growth, development and yield. The results showed that by supplying rational micro - fertilizer of Boron and zinc, the growth and development of the first pair cotyledonary branch, root nodules leaves and pods could be promoted, the yield was significantly increased on the basis of supplying rational Nitrogen, Phosphorus and Potassium. In this experiment, supplying Boron 7.5 kg/hm^2 and 11.25 kg/hm^2 could increase by 6.87% and 8. 19% in comparison with CK, supplying Zinc 7.5 kg/hm^2 and 11.25 kg/hm2 could increase by 7.17% and 5.20% in comparison with CK. We think fertilizing Boric acid 11.25 kg/hm^2、Zinc sultate 7.5 kg/hm^2 is appropriate on the basis of supplying rational Nitrogen, Phosphorus and Potassium.
