沼渣基质对温室番茄生长和产量的影响

Effects of Using Biogas Residue as Substrate on the Growth and Yield of Tomato in Greenhouse

利用沼渣和炉渣以不同体积比混合作基质,研究沼渣对温室番茄生长和产量的影响。结果表明,沼渣和炉渣复合基质的理化性状完全达标;沼渣促进了番茄植株的生长,提高了番茄果实产量和品质,其中,3份沼渣+1份炉渣处理的番茄植株根系活力最强,前3穗果实产量最高;为0.93kg.株-1;糖酸比最高,为6.24。

This experiment using biogas residue and coal cinder to study their effects on the growth and yield of tomato in greenhouse. The results showed that the physical and chemical properties of the mixed substrates could meet the requirement of tomato plant growth. Biogas residues could accelerate tomato growth, improve its yield and quality. Among all treatments, the treatment of 3 biogas residue ＋ 1 coal cinder （V/V） had achieved the highest root activity and the highest yield （ per plan of the first three fruit cluster yields 0. 93 kg） and the highest ratio of sugar to acid （6. 24）.
