摘要
以西湖淤泥为主要原料 ,配以砻糠灰、干鸡粪、菜籽饼等 ,组配低成本有机型基质 ,旨在合理开发利用西湖淤泥。处理 (西湖淤泥 +砻糠灰 +干鸡粪 )与处理 (西湖淤泥 +砻糠灰 +菜籽饼 )均有良好的理化性质 ,其孔隙度、有机质含量及 N、P、K含量适宜樱桃番茄的生长。处理 樱桃番茄早期营养生长及前期产量、总产量等方面与对照 (泥炭 +珍珠岩 +泡沫粒 )无显著性差异 ,果实中 Vc含量显著高于对照。处理 早期营养生长不如对照 ,但前期产量、总产量与对照无显著性差异 ,干物质、Vc含量与糖度显著高于对照。处理 、处理 的成本约为对照的 1/2左右。
A greenhouse experiment was carried out with mini-tomato to establish a method for the application of the sediment from West Lake as organic substrate. In the trial, there were three treatments as CK (peat+pearlite+aerated plastic), Treatment Ⅰ(sediment+ash of rice hull+dried fowl feces) and Treatment Ⅱ(sediment+ash of rice hull+rape-seed cake). The physico-chemical properties, such as the contents of organic matter, available N, P, K, and the porosity, of the substrates in Treatment Ⅰ and Ⅱ were suitable for the growth of mini-tomato. The results indicated that the early-stage and total fruit yields of mini-tomato were no significant differences among the three treatments, though the vegetable growth at the early stage of the mini-tomato in Treatment Ⅱ was lower than that in CK. It was also found that the Vc contents of the fruits of Treatment Ⅰ and Ⅱ were higher than that of CK, and the contents of dry matter and sugar of the fruits of Treatment Ⅱ were higher than that of CK as well. The costs of the substrates in Treatment Ⅰ and Ⅱ were about half of that in CK. The sediment from West Lake can be used as organic substrate for vegetable culture. ;
