Abstract
[Objective] The preliminary study on soilless culture of greenhouse tomato was conducted with some fermented agricultural organic waste.[Method] With tomato cv.'Jinpeng Chaoguan'as material,the experiment studied the influences of different compound substrates on growth,yield and quality of tomato under plastic tunnel during spring-summer season.Four kinds of compound substrates(substrate A:60% corn straw +20% river sand +20% cattle manure;substrate B:50% corn straw +10% corn cob +20% river sand +20% cattle manure;substrate C:50% corn straw +10% rice husk +20% river sand +20% cattle manure;substrate D:40% corn straw +10% corn cob +10% rice husk +20% river sand +20% cattle manure),were prepared with different ratios of corn straw,corn cob,rice husk(all fermented by King Baby microbial ferment agent),cattle manure(natural fermentation)and river sand,combined with dried chicken manure and the ternary compound fertilizer as topdressing.Two treatments were used as control:50% peat + 25% perlite + 25% vermiculite(CK1)was taken as the substrate control of organic ecotype culture and the conventional soil culture(CK2)was taken as the control of substrate culture.[Result] The equivalent basic fertilizer was added in the four kinds of compound substrates before cultivation.Before cultivation the physicochemical properties of the four kinds of compound substrates,such as bulk density,total porosity,pH and EC,were all in the appropriate ranges of an ideal soilless culture substrate for tomato.The plant height and stem diameter of tomato throughout the whole growth period of crop field setting were found close to CK1 and CK2 only in the substrate B.At the end of experiment the root-shoot ratio of tomato cultivated in the substrate B was the largest.Among the four kinds of compound substrates the cultivation effects of the substrate B was the best one,whose yield decreased by 1.1% and 1.9% respectively compared with CK1 and CK2.Both the ratio of sugar and acid and the content of vitamin c of tomato cultivated in the substrate B significantly increased by 72.3% and 13.0% respectively compared with CK2.The content of nitrate in tomato cultivated in the substrate B significantly decreased by 26.1% than that in CK2.[Conclusion] The compound substrate B can be used in soilless culture of greenhouse tomato instead of using peat,so as to reach the goal of solving soil salinization and continuous cropping obstacle by resource-utilizing agricultural residue and improving the fruit quality.
