生物有机肥对冬瓜生产示范与推广效果研究

Effect of Bio-organic Fertilizer on Production Demonstration and Promotion of White Gourd

为减少无机肥使用量,改善土壤微生物结构,提高青皮冬瓜产量和质量,对"一沣"系列生物有机肥在青皮冬瓜生产上应用效果进行了研究。结果表明:施用生物肥料后促进了土壤微生物和有益微生物的生长繁殖,土壤的速效N、P、K、有机质和阳离子交换量都得到提高。青皮冬瓜施用生物肥料后,在茎粗、叶面积、果重、商品率等方面都比施用农家肥和化学肥料有较大幅度提高。试验区施用生物肥料产量比农家肥增加7.9%,比单施化肥增产26.9%;每平方米施用生物肥料比施用农家肥和单质化肥分别增收1.841元和5.985元。

To reduce the application amount of inorganic fertilizer, improve soil structure and the yield and quality of white gourd, application effects of ＂Yifeng＂ series of bio-organic fertilizers on white gourd were studied. The results showed that the growth and propagation of soil microorganisms and beneficial microorganisms were enhanced after the application of bio-organic fertilizer, and the available N, P, K, organic matter and CEC of soil were improved. The growth in stem diameter, leaf area, and fruit weight and commodity rate of white gourd under the treatment of hio-organic fertilizer was higher than that under farm manure and chemical fertilizer treatment. The yield in the experiment plots applied with bio-organlc fertilizers was 7.9% and 26.9% higher than that of farm manure and chemical fertilizer, respectively, and the income increased by 1.841 yuan/m^2and 5.985 yuan/m^2, respectively.
