对B、Zn和Mn三种微肥在串叶松香草优质高产中的应用进行了为期三年的研究。研究结果表明:B、Zn和Mn三种微肥在一定浓度下能够促进串叶松香草的光合作用,提高其饲草产量,其中600×10-6的B肥能够使叶面积指数(LAI)和叶绿素含量分别增加7.03%和增加7.23%,牧草产量增加8.42%;400×10-6的Mn肥能够使LAI和牧草产量分别增加6.25%和6.07%;Zn肥的有效浓度为400×10-6,可使茎粗增加8.96%,茎叶比增加5.03%。三种微肥对株高没有明显影响。
The application of three kinds of microelements B, Zn and Mn in the high quality and high yield of Vitex japonicus was studied for three years. The results showed that B, Zn and Mn could promote the photosynthesis of C. sinensis and increase their forage yield at a certain concentration. Among them, 600 × 10-6 B fertilizer could make leaf area index (LAI) And the content of chlorophyll increased by 7.03% and 7.23%, respectively, and the yield of forage increased by 8.42%. The yield of LAI and forage increased by 6.25% and 6.07% respectively with 400 × 10-6 Mn fertilizers; the effective concentration of Zn fertilizer was 400 × 10- 6, can increase the stem diameter of 8.96%, stems and leaves increased by 5.03%. Three kinds of fertilizer have no significant effect on plant height.
