中文摘要:研究2种不同电导率有机营养液对番茄生长发育的影响,为有机营养液水培可以改善果实品质提供依据,试验以番茄为试材,番茄茎秆有氧堆制腐熟和厌氧堆制腐熟后的有机物料经浸提后所获得的2种浸提液作为有机营养液,即有氧有机浸提液(T1,T2,T3)和厌氧有机浸提液(Y1,Y2,Y3),分别稀释至电导率(EC值)为1 mS·cm-1(T1,Y1)、2 mS·cm-1(T2,Y2)、4 mS·cm-1(T3,Y3)水培番茄,以日本山崎营养液作为对照(CK)。结果表明,有机营养液生物量指标与产量指标显著低于CK;有氧有机营养液叶绿素质量分数随EC值增加而增加,T1(1 mS·cm-1)、T2(2 mS·cm-1)、T3(4 mS·cm-1)叶绿素质量分数显著低于CK;厌氧有机营养液叶绿素质量分数随EC值增加呈先升后降的变化趋势,Y1(1 mS·cm-1)、Y2(2 mS·cm-1)、Y3(4 mS·cm-1)叶绿素质量分数均显著高于CK;有氧有机营养液光合能力随EC值增加而增加,T1、T2、T3光合能力显著低于CK,厌氧有机营养液光合能力随EC值增加呈先升后降的变化趋势,其中Y2显著高于CK;厌氧有机营养液可溶性固形物、糖酸比、维生素C及可溶性蛋白均随EC值增加呈现先升后降的趋势,Y2可溶性固形物、糖酸比、维生素C及可溶性蛋白均显著高于CK,有机营养液各处理硝酸盐显著低于CK。利用番茄茎秆堆肥得到的厌氧有机营养液能提高番茄叶片叶绿素质量分数和光合能力,改善番茄品质,其中最佳的处理为厌氧有机营养液Y2(2 mS·cm-1)处理。

Effect Analysis of Hydroponic Tomato with Different Organic Nutrient Solution
Abstract:For providing a basis of fructification improvement by hydroponic cultivation of organic nutrient solution,we studied the effect of two kinds of organic nutrient solutions with different electrical conductivities on the growth and development of tomato.With tomato as material and the Japanese Yamazaki nutrient solution was used as a contrast,two kinds of extracts from tomato stalk were taken as nutrition solution after fermented by aerobic fermenting and anaerobic fermenting,namely aerobic and anaerobic nutrition organic solution, it were diluted to electrical conductivity of 1 mS·cm-1, 2 mS·cm-1, 4 mS·cm-1 to culture tomato.The results showed that the biomass index and yield index of organic nutrient solution were all significantly lower than the CK. The chlorophyll mass fraction of aerobic organic nutrient solution increased with the increase of EC value, and the chlorophyll mass fraction of T1(1 mS·cm-1), T2(2 mS·cm-1) and T3(4 mS·cm-1) were all significantly lower than that of the CK; the chlorophyll mass fraction of anaerobic organic nutrient solution increased first and then decreased with the increase of EC value. The chlorophyll mass fraction of Y1(1 mS·cm-1), Y2(2 mS·cm-1), Y3(4 mS·cm-1) were significantly higher than CK. The photosynthetic capacity of aerobic organic nutrient solution increased with the increase of EC value. The photosynthetic capacity of T1, T2 and T3 were significantly lower than that of CK, and the photosynthetic capacity of anaerobic organic nutrient solution increased first and then decreased with the increase of EC value, in which Y2 was significantly higher than CK. The mass fraction of soluble solids, sugar-acid ratio, vitamin C and soluble protein in anaerobic organic nutrient solution increased first and then decreased with the increase of EC value. Y2 soluble solids, sugar-acid ratio, vitamin C and soluble protein were significantly higher. In CK, the nitrate of organic nutrient solution was significantly lower than that of CK. Anaerobic organic nutrition solution made by tomato stalk anaerobic fermenting could improve chlorophyll mass fraction of tomato leaves,the photosynthesis and quality of tomato. The best treatment was anaerobic organic nutrient solution Y2(2 mS·cm-1).
