土壤微生物菌剂对大棚油桃植株特性的影响研究

Effects of soil microbial inoculants on plant characteristics of Nectarine in Greenhouse

以油桃品种‘离核甜’为试材,研究了5种土壤微生物菌剂对大棚油桃植株特性的影响。结果表明:施用5种土壤微生物菌剂对‘离核甜’油桃的植株特性均产生了较大影响,其中处理4对增加株高、胸径效果最好,胸径增加与CK差异显著;减少了叶芽数,促进新枝生长,具有增加新枝节间距离,增加叶长、叶宽、Pn、Tr、Chi等作用,整体效果最好;其次是处理5,对花芽数有促进作用,与CK相比差异显著,能提高叶片的Pn。

The effects of five soil microbial inoculants on the characteristics of Nectarine plants in greenhouse were studied taking nectarine variety ′ Freestone sweet′ as test materials. The results showed that 5 kinds of soil microbial inoculants had a great effect on the plant characteristics of nectarine. The overall effect of treatment 4 was best, which had the best effect on increasing plant height and DBH, and the difference between DBH and CK was significant. It could reduce the number of leaf buds, promote the growth of new branches, increase the distance between new branches, increase the length, width, Pn, Tr and Chi of leaves and so on. The treatment 5 promoted the number of flower buds, which was significantly different from that of CK, and increased the Pn of leaves.
