以甜瓜脆玉1号为材料,采用大田随机区组设计,设置0、30、60、90、120和150kg·hm^-2细胞分裂素生产菌群的混合菌剂处理,研究其对甜瓜营养元素和根际土壤微生物含量的影响。结果表明：施用细胞分裂素生产菌能提高甜瓜根、茎、果实中氮、磷、钾、镁和铁含量以及根际土壤微生物（真菌、细菌和放线菌）含量,且随着施用量的增加而增加。其中施用150kg·hm^-2混合菌剂处理果实中镁和铁含量分别比对照增加30.4%和58.3%;施用90kg·hm^-2混合菌剂处理大幅度提高根际土壤真菌、细菌和放线菌含量,分别比对照增加209.6%、711.1%和229.1%。这一研究说明施用细胞分裂素生产菌可提高甜瓜根、茎顶、茎中、茎基以...

This study was designed to explore the effects of different dosage of mixed cytokinin producing bacteria (CPB) on the nutrition elements content and rhizosphere microbes content of the muskmelon.With Cuiyu No.1 (the muskmelon variety) as the plant material,a single-factor with five-levels treatment was designed.The treatments include applying 0,30,60,90,120 and 150 kg · hm-2 mixed CPB (T0,T30,T60,T90,T120,T150,respectively) and the treatment of no CPB application was used as control (T0).All treatments were arranged using the randomized comple...
