本试验以结球生菜“射手101”为试材,研究了不同有机肥对其生长、产量、品质和经济效益的影响。试验结果表明:与对照相比,施用军龙源有机肥后,增产8.1%,硝酸盐含量降低17.8%、亚硝酸盐含量降低31.0%,增收147元。施用蘑菇渣堆肥和牛粪堆肥后,结球生菜的株高、茎粗、叶片数、叶面积和产量均有不同程度的降低,其中产量分别减少9.1%和12.3%,效益减少1 161元/亩和1 546元/亩。在本试验条件下,综合生菜长势、产量、品质和经济效益等指标,军龙源有机肥可以作为本地区结球生菜适宜的有机肥。
In this experiment, the effects of different organic fertilizers on the growth, yield, quality and economic benefits were studied by using the knot lettuce “shooter 101 ” as test material. The results showed that compared with the control, the application of Junlongyuan organic fertilizer increased 8.1%, the nitrate content decreased 17.8%, the nitrite content decreased 31.0% and the income increased by 147 yuan. After applying the mushroom compost and cow dung composting, the plant height, stem diameter, number of leaves, leaf area and yield of knotted lettuce decreased to different extents, the output decreased 9.1% and 12.3% respectively, and the benefit decreased by 1 161 yuan / mu And 1,546 yuan / mu. Under the test conditions, taking into account indicators such as lettuce growth, yield, quality and economic benefits, Army Longyuan Organic Fertilizer can be used as a suitable organic fertilizer for lettuce in the area.
