探析不同育苗基质对黄瓜幼苗生长的影响.doc

专业资料参考首选探析不同育苗基质对黄瓜幼苗生长的影响摘要: 以腐熟中药渣、泥炭、蛭石、珍珠岩为原料,按照不同比例复配成 4 种育苗基质,选取南京市蔬菜所的通用型育苗基质作为对照, 研究不同配比的育苗基质对黄瓜苗期生长的影响。结果表明: 基质 B 培育的黄瓜在株高、茎粗、根长、根表面积以及壮苗指数上均显著优于其他配比的育苗基质, 育苗效果显著提高, 可推荐作为黄瓜育苗的专用型育苗基质。 Abstract: the rotten in the medical, peat, vermiculite and perlite as raw material, according to the different proportion distribution into 4 kinds of substrate, selection of nanjing vegetables universal seedling substrate parison, the different proportion of substrate effects on cucumber seedling growth. Results show that the matrix B cultivation of cucumber in plant height, stem diameter, root length, root surface area and strong seedling index were significantly better than other seedling substrate ratio, have significantly improved effect, can be mended asa special seedling of cucumber seedling substrates. 关键词: 育苗基质;黄瓜;幼苗;生长;影响 Key words: seedling substrate; Cucumber; Seedling; They grow. impact / / 随着人们对生存环境质量要求的不断提高, 对蔬菜水果的供应量和品质要求急速增加。种苗工厂化生产( 穴盘育苗) 因具有节能、生产效率高、秧苗素质好、缓苗快、成活率高、适于长距离运输等优点而越来越受到重视。 With the constant improvement of the people quality requirements of survival environment, the rapid increase of fruits and vegetables supply and quality requirement. Seedlings factory production (hole plate seedling) for energy saving, high production efficiency, the quality is good, quick slow seedlings, the advantages of high survival rate, suitable for long distance transportation and more and more be taken seriously. 育苗是蔬菜栽培的重要措施, 育苗基质则是穴盘种苗生产的基础物质, 而基质良好的理化性状直接影响秧苗的壮弱, 从而影响到蔬菜的长势和产量。但是传统的育苗方法, 具有土传性病害严重、成活率低、缓苗期长、生长发育慢等缺点[1] , 已无法满足发展日益快速的农业生产。 Seedlings is one of the important measures, vegetable cultivation of matrix is the hole plate seedling production base material, the substrate with good physical and chemical properties directly affect the seedlings strong weak, which affects the growth and output of the vegetables. But traditional seedling raising method, with soil / / borne disease serious, low survival rate, long slow seedling stage, slow growth of the disadvanta
