微量元素和氮、磷、钾一样,是植物正常生命过程中必须的物质,在缺乏微量元素的土壤中施用微量元素肥料,是进一步发挥农业生产潜力的有效途径。寄主植物是紫胶生产的物质基础。我们对优良灌木寄主植物——木豆,施用微量元素肥料。结果表明,喷施土壤供给不足的钼、硼元素能促进木豆植株生长,使地径比对照增粗12.7—14.4％,宜胶枝总长度增加16.7—19.2％。随着植株生长状况的改变,紫胶产量也较对照提高8.5—9.4％。现将初步结果总结如下。
Trace elements, like nitrogen, phosphorus and potassium, are necessary substances in the normal course of life of plants. Application of trace element fertilizers in the soil lacking trace elements is an effective way to further develop the potential of agricultural production. Host plants are the material basis for shellac production. We are good host plants shrubs - wood beans, the application of trace element fertilizer. The results showed that the application of molybdenum and boron in insufficient supply of soil could promote the growth of the plant, making the diameter of the plant grow 12.7-14.4% more than that of the control, and the total length of the suitable plantlets increased by 16.7-19.2%. With the change of plant growth, the production of shellac also increased by 8.5-9.4% compared with the control. The preliminary results are summarized below.
