摘要
为研究不同水溶肥料配施在设施番茄水肥一体化中的应用效果,采用田间试验和室内试验相结合的方法,研究了大量元素水溶肥料、中量元素水溶肥料、含腐植酸水溶肥料、含氨基酸水溶肥料(中量元素型)、含氨基酸水溶肥料(微量元素型)等5种常见水溶肥料组配对番茄产量、品质及土壤养分含量的影响。结果表明:施用不同组合水溶肥料均可以改善番茄农艺性状,具有显著的增产效果,大量元素、大量元素+中量元素、大量元素+含腐植酸、大量元素+含氨基酸(中量元素型)、大量元素+含氨基酸(微量元素型)水溶肥料处理667 m^(2)产量分别比清水对照提高8.3%、10.2%、5.3%、5.6%和6.4%;同时还能改善番茄的品质和土壤养分状况,各处理VC含量分别比对照增加8.7%、13.4%、23.8%、19.2%和16.9%,可溶性固形物含量分别比对照增加11.3%、14.5%、25.8%、24.2%和22.6%。综合追肥效果,建议在设施番茄生产中,按照大量元素+中量元素水溶肥料处理施肥以提高产量,或按照大量元素+含腐植酸水溶肥料处理施肥以提高番茄品质。
In order to study the application effect of different water-soluble fertilizers on the integration of water and fertilizer in tomatoes'planting,fi eld experiment and laboratory experiment were combined to study the effect of the composition of fi ve common water-soluble fertilizers on tomato yield,quality and soil nutrient content,including massive-element water-soluble fertilizer,medium-element water-soluble fertilizer,humic acid water-soluble fertilizer,amino acid water-soluble fertilizer(medium-element type)and amino acid watersoluble fertilizer(trace-element type).The results showed that application of massive-element water-soluble fertilizer,massive-element+medium-element water-soluble fertilizer,massive-element+humic acid watersoluble fertilizer,massive-element+amino acid water-soluble fertilizer(medium-element type)and massiveelement+amino acid water-soluble fertilizer(trace-element type)could improve the agronomic characters of tomato and had a signifi cant increase effect on yield.Compared with that of clean water control,the yield per 667 m2 of each treatment was increased by 8.3%,10.2%,5.3%,5.6%and 6.4%,respectively.At the same time,tomatoes quality and soil nutrient status could also be improved,the VC content of each treatment increased by 8.7%,13.4%,23.8%,19.2%and 16.9%,respectively compared with that of control,and the soluble solid content increased by 11.3%,14.5%,25.8%,24.2%and 22.6%,respectively.According to the comprehensive topdressing effect,it was suggested to apply fertilizer treatment with massive-element+medium-element water-soluble fertilizer to improve fruit yield,or apply fertilizer treatment with massive-element+humic acid water-soluble fertilizer to improve tomato quality in facility production.
