为了探索适合番茄无土育苗的营养液配方,以番茄品种“钻石红1189”为试材,研究了4种营养液配方对番茄幼苗生长及光合色素含量的影响。结果表明:与对照相比,各营养液处理均能显著促进幼苗的生长,而荷兰配方、霍格兰德配方和园试配方对株高的促进作用显著大于山崎配方;营养液处理也能显著增加幼苗的茎粗和鲜质量,但不同配方间无显著差异;对于根系长度而言,荷兰配方处理的幼苗根系长度显著大于其它3种营养液处理及对照;荷兰配方、山崎配方和霍格兰德配方处理的幼苗根冠比显著大于对照,而园试配方处理的根冠比与对照无显著差异;从光合色素指标来看,园试配方处理的幼苗叶片叶绿素a、叶绿素b含量最高,园试配方与霍格兰德配方处理的叶片类胡萝卜素含量显著高于其它处理;综合各指标表现得出,荷兰配方培养的番茄幼苗生长表现最好,是番茄无土育苗最佳的营养液配方。
In order to explore the nutrient solution suitable for tomato soilless seedlings, the effects of four kinds of nutrient solutions on tomato seedling growth and photosynthetic pigment content were studied using the tomato variety Diamond 1189 as test material. The results showed that: Compared with the control, the treatment of nutrient solution can significantly promote the growth of seedlings, while Holland formula, Hoagland formula and garden test formulations on plant height was significantly greater than the Yamazaki formula; nutrient solution treatment can also be significant Increase seedling stem diameter and fresh weight, but there is no significant difference among different formulas. For root length, root length of seedlings treated by Dutch formula is significantly greater than that of the other three nutrient solution treatments and controls; Dutch formula, Yamasaki formula and Hoagland The root-shoot ratio of seedlings treated with German recipe was significantly larger than that of the control, while the root-shoot ratio of the plant test was not significantly different from that of the control. From the photosynthetic pigment index, the contents of chlorophyll a and chlorophyll b were the highest The content of carotenoids in leaves of Hogland recipe was significantly higher than that of other treatments. According to the indexes, the Dutch tomato seedlings grew best and the best nutrient solution .
