| 摘 要： | 以‘L-402'番茄为试材,采用“311-B”最优组合设计法,研究了氮肥、磷肥和钾肥对温室番茄品质的影响.结果表明:番茄果实中硝酸盐积累量会随着施用的氮肥或钾肥的增加而增加,在一定范围内适当增施磷肥会降低番茄果实中硝酸盐的积累量；同时,增施磷肥会提高番茄果实中可溶性糖含量,而增施钾肥则会增加番茄果实中可溶性糖、维生素C和氨基酸含量.因此适宜的氮磷钾配比可有效提高番茄果实的营养品质,该试验条件下,氮肥(N)、磷肥(P2O5)和钾肥(K2O)的适宜用量分别为75.0、160.8、352.0 kg/hm2.

| Abstract: | Using'L-402'tomato as test material,effects for the different proportion of nitrogen,phosphate and potassium on tomatoes quality were studied in greenhouse by the method of'311-B'optimummixed design.The results showed that the amount of accumulated nitrate in tomato were increased by the excessive quantity of nitrogen or potassium.And that would be reduced by appropriately increment of phosphate.The sugar content was increased by increasing the amount of phosphate,and the level of the suger content soluble ... |
