中文摘要:
      采用田间小区试验,以商品水溶肥为对照(CK),研究了新型水溶性肥料聚磷酸铵(T1)、工业级磷酸氢二铵(T2)和磷酸脲(T3)对番茄生长、产量和品质的影响。结果表明:T1和T3可促进番茄生长,定植后53d,T1处理的番茄茎粗比CK高23.79%,定植后93d,T1的SPAD值为35.45,比CK高32.03%。T1和T3产量分别比CK高出12.64%、4.74%。与CK相比,T1的可溶性糖含量、土壤全氮含量、有机质含量、EC分别提高9.17%、2.5%、13.7%、81.1%,土壤pH值降低了0.07个单位,但NO3-N含量较高。综上所述,聚磷酸铵在番茄上的应用效果最佳。
英文摘要:
      Abstract: Using commodity water soluble fertilizer as contrast, a field plot experiment was conducted to study the effect of the new water soluble fertilizer—ammonium polyphosphate (T1), industrial-grade ammonium phosphate (T2) and urea phosphate (T3) on tomato yield, quality and soil nutrient. The results showed that T1 and T3 could promote tomato growth. T1 increased the stem diameter by 23.79%, 53 days after engraftment. 93 days after engraftment, SPAD value of T1 was 35.45, increased by 32.03% than CK. The yield of T1 and T3 were increased by 12.64% and 4.74% than CK, respectively. Compared with CK, the soluble sugar content of tomato fruit, the total nitrogen content, soil organic matter and EC were increased by 9.17%, 2.5%, 13.7% and 81.1%, respectively, soil pH was reduced by 0.07 and NO3-N content was higher. In summary, the application effect of ammonium polyphosphate was the best.
