摘要
通过田间试验,研究了不同施肥模式对设施番茄产量、品质和经济效益。结果表明,与常规施肥[667 m^(2)基施鸡粪有机肥1100 kg+硫酸钾复合肥(17-17-17)50 kg、追施水溶性肥料(13-7-40)28 kg]相比,优化施肥2[OPT2,667 m^(2)基施商品有机肥300 kg+硫酸钾复合肥(18-6-16)40 kg、追施水溶性肥料(16-6-30)28kg]的番茄茎粗、单株果数和产量分别显著增加10.6%、11.2%和7.7%;OPT_(2)处理的番茄可溶糖和VC含量较CK分别显著提高17.9%和30.5%。优化施肥措施的番茄经济效益均有所提高,番茄的纯收益表现为OPT2>OPT1>CK。因此,OPT_(2)可在设施番茄生产中推广和应用。
Through field tests,the effects of different fertilization modes on yield,quality and economic benefit of greenhouse tomato were studied.The results showed that compared with conventional fertilization[667 m^(2) basal application of chicken manure organic fertilizer 1100 kg+potassium sulfate compound fertilizer(17-17-17)50 kg,topdressing water-soluble fertilizer(13-7-40)28 kg],optimized fertilization 2[OPT_(2),667 m^(2) basal application of commercial organic fertilizer 300 kg+potassium sulfate compound fertilizer(18-6-16)40 kg,topdressing water-soluble fertilizer(16-6-30)28 kg]significantly increased the stem diameter,fruit number per plant and yield of tomato by 10.6%,11.2%and 7.7%,respectively.The soluble sugar and VC content of tomato treated with OPT2 were significantly increased by 17.9%and 30.5%compared with CK,respectively.The economic benefits of tomato were improved by optimized fertilization measures,and the net income of tomato was OPT_(2)>OPT1>CK.Therefore,OPT2 could be promoted and applied in facility tomato production.
