沼肥对保护地番茄产量、品质和土壤肥力的影响

The Research of Marsh Fertilizer Impact on Tomatoes' Output, Quality and Soil Fertility in Protected Field

采用田间小区试验,研究了沼肥对番茄产量、品质及其土壤肥力的影响。试验结果表明,沼肥可以促进番茄生长发育,提高产量,改善果实品质,增加土壤中有机质、全量养分及速效养分的含量。表现为施用沼肥比不施肥增产88.24%,比等养分的化肥增产7.87%,产量差异达到极显著水平;果实中可溶性固形物、维生素C、糖酸比,比不施肥处理分别增加9.03%、23.69%、13.28%,比化肥处理分别增加12.26%、15.37%、28.49%,土壤耕层有机质、全氮、全磷、碱解氮、速效磷、速效钾与试前本底养分相比分别增加了12.70%、9.52%、7.50%、4.33%、74.77%、17.58%。

The effect of marsh fertilizer on output, quality and soil fertility of the tomato were studied in the field. Results indicated that marsh fertilizer can not only increase the tomato yield, but also increase the content of organic matter, total nutrient and rapidly available nutrient in the soil. It showed that in using marsh fertilizer, output of tomato were respectively 88.24% higher than that in not using marsh fertilizer and 7.87% than that in using chemical fertilizer. The content of soluble solid contents, vitamin C and sugar of the fruit were respectively 9.03%, 23.69%, 13.28% and 12.26%, 15.37%, 28.49% higher than that in not using marsh fertilizer and in using chemical fertilizer. The contents of organic matters, total nitrogen, total phosphor, alkali nitrogen and available kalium in the soil were respectively I2.70%, 9.52%, 7.50%, 4.33%, 74.77% and 17.58% higher than that of basal nutrient.
