酵素菌肥不同施用量对露地番茄产量和品质的影响

Effect of Different Application Amounts of Microbial Organic Fertilizer on Quality and Yield of Open Field Tomato

以加工番茄品种"屯河8号"为试验对象,以酵素菌生物有机肥为供试材料,通过田间试验,研究了酵素菌肥不同施用量对露地加工番茄产量和品质的影响。结果表明:各处理固定配施50%化肥后,综合评价以施用酵素菌肥600kg/667m2的各指标表现最优,可显著提高番茄叶片叶绿素SPAD值10.29%、光合速率33.76%;降低土壤容重6.34%;降低土壤全盐28.70%;提高土壤有机质51.86%、速效磷117.75%、速效钾36.17%,土壤肥力水平得到显著提升;提高番茄成熟度118.45%,增产98.45%,且番茄品质较优良,可视为最适宜用量,其次效果为施用酵素菌肥400kg/667m2。

Taking processing tomato of ＇Tunhe No.8＇ as experiment objects,and microbial organic fertilizer as material,the influence of different microbial organic fertilizers on yield and quality of open field tomatoes were studied.The results showed that each treatment that fixed with 50% chemical fertilizer,application of microbial organic fertilizer 600 kg/667m2 was the best among treatments under comprehensive evaluation,increased the chlorophyll SPAD values of tomato 10.29% significantly,photosynthetic rate 33.76%;reduced soil bulk density of 6.34%;soil salt 28.70%;increased soil organic matter 51.86%,rapid available phosphorus 117.75%,rapidly available potassium 36.17%.Significantly improved soil fertility levels;tomato maturity improved by 118.45%,yield by 98.47%,and the quality of tomato excellent,was the most appropriate application rate,next was application of 400 kg/667m2.
