中文摘要:
      采用田间试验的方法,研究增施生物有机肥对番茄生长发育、产量、品质及土壤有效养分的影响。结果表明,增施生物有机肥,对番茄生育期影响不大,但可以提高番茄植株长势,单果重和果实大小,最主要是在增加产量方面效果明显,还可以降低硝酸盐含量,且提高可溶性糖、Vc 含量;增施生物有机肥也可以调节土壤pH值,改良盐碱对植物的伤害,增加有机质、碱解氮、有效磷、速效钾含量;通过增施不同比例有机肥试验,发现在早春设施番茄生产中,有机肥和三元复合肥比例以3/5为最优。
英文摘要:
      The effect of biological organic fertilizer on the growth, yield, quality of tomato and the content of soil available nutrients was studied by the method of field experiment. The results showed that the growth period of tomato was not affected by the biological organic fertilizer. In addition, the weight and size of single tomato fruit was affected by the biological organic fertilizer, especially in the yield. Furthermore, the content of nitrate in field was reduced. The content of soluble sugar and Vc increased with the weight of soil available nutrients. We also found that the pH of the soil could be adjusted by biological organic fertilizer. At the same time, the content of organic matter, alkali-hydrolyzable nitrogen, available phosphorus, and quick-acting potassium increased with the increase of biological organic fertilizer.In conclusion, the best ratio of organic fertilizer and N,P,K compound fertilizer is 3:5 in greenhouse of the early spring. ;
