摘要
试验研究了化肥、生物有机无机复合肥、生物有机肥、沼肥对日光温室秋冬茬黄瓜及对土壤理化性质的影响。试验结果表明,施用沼肥、生物有机肥、生物有机无机复合肥有改善土壤理化性状、增强土壤保水保肥能力的作用。表现为与试前土壤相比较,土壤容重下降,土壤总孔隙度和土壤含水量增加,其中施用沼肥的处理影响最大,土壤容重降低了4.26%,土壤总孔隙度和土壤含水量分别提高了4.68%,10.7%;施用沼肥,耕层土壤有机质、全氮、速效钾含量增加最高,而完全施用生物有机无机复合肥的处理全磷、速效磷、碱解氮增幅最大。施用沼肥和生物有机无机复合肥可以促进黄瓜的生长和提高产量,产量比对照(不施肥处理)分别增加了102.8%,123.1%。各处理除沼肥和生物有机肥两处理间产量差异不显著外,其他处理间差异均达极显著水平。另外,施用沼肥、生物有机肥、生物有机无机复合肥可以提高果实中Vc、还原糖含量,并降低硝酸盐含量,提高了果实品质。
We researched the effects of the chemical fertilizer, biological-organic-inorganic compound fertilizer, biological-organic fertilizer and fen manure, which were applied to the cucumber in greenhouse in autumn and spring, on the physiological and chemical characteristics of soil and cucumber. The result showed that using the biological-organicinorganic compound fertilizer, biological-organic fertilizer and fen manure would have effected on the improvement of the soil physiochemical properties, enforcing the ability of moisture reserve of soil. It indicated that soil bulk density decreased, soil total porosity and soil moisture capacity increased. The most significant effect was found in the treatment of applying of fen manure, with soil bulk density decreased by 4.26%, soil total porosity and increased by 4.68% and 10.7 % respectively. The content of soil organic matter, total soil nitrogen and soil available potassium in the plough layer have the most level after utilization of fen manure, but it was also showed that the increased amount of soil total phosphorus, soil available phosphorus and alkali dispelled nitrogen had the highest level after using biological-organic-inorganic compound fertilizer. The fen manure and biological-organic-inorganic compound fertilizer could improve the growth of cucumber and was responsible for improvement of its product, with increasing by 102.8 % and 123.1% respectively compared with the treatment of no fertilizer. No differences were found significantly between the treatment of fen manure and the treatment of biological-organic-inorganic compound fertilizer, but there were the significant differences in the other treatments. In addition, applying of fen manure and biological-organic fertilizer, biological-organic-inorganic compound fertilizer may improve the content of vitamin C and reducing sugar in the fruit, meanwhile with nitrate decreased, so they could improve the quality of products.
