无土栽培的装置无土栽培所需装置主要包括栽培容器、贮液容器、营养液输排管道和循环系统。1.栽培容器主要指栽培花卉的容器，常见有塑料钵、瓷钵、玻璃瓶、金属钵和瓦钵等。主要以容器壁不渗水为好。2.贮液容器包括营养液的配制和贮存用容器，常用塑料桶、木桶、搪瓷桶和混凝土池。容器的大小要根据栽培规模而定。3.营养液输排管道一般采用塑料管和镀锌水管。4.循环系统主要由水泵来控制，将配制好的营养液从贮液容器抽入，经过营养液输排管道，进入栽培容器无土栽培是指不用天然土壤、而用营养液来栽培作物的方法,当前主要用于蔬菜、花卉和树木育苗。目前生产上常用有水培、砂砾培、珍珠岩+泥炭培和锯末培等.无土栽培与常规栽培的区别，就是不用土壤，直接用营养液来栽培植物。为了固定植物，增加空气含量，大多数采用砾、沙、泥炭、蛭石、珍珠岩、岩棉、锯木屑等作为固定基质。其优点可以有效地控制花卉在生长发育过程中对温度、水分、光照、养分和空气的最佳要求。由于无土栽培花卉不用土壤，可扩大种植范围，加速花卉生长，提高花卉质量，节省肥水，节省人工操作，节省劳力和费用。缺点是，一次性投资较大，需要增添设备，如果营养源受到污染，容易蔓延，营养液配制需要技术知识。(一)无土栽培的方法无土栽培的方法很多，目前生产上常用有水培、砂砾培、珍珠岩+泥炭培和锯末培等。1.水培是指花卉根系连续或不连续浸入营养液中栽培的方法。为了提高营养液中的含氧量，一般需要通气设施。主要适用于球根花卉如风信子、朱顶红、郁金香、黄水仙等。2.砂砾培是采用直径大于3毫米和小于1厘米的小石子作固定基质的无土栽培方法。应用比较广泛，常用于木本观赏植物月季、山茶、杜鹃、茉莉等。3.珍珠岩+泥炭培用珍珠岩与泥炭混合基质作盆栽花卉固定基质的较为普遍，常用于仙客来、大岩桐、非洲紫罗兰、球根秋海棠等开花盆栽花卉。4.锯末培采用中等粗度的锯末加适当谷壳混合作为固定基质的无土栽培方法，常配用滴灌系统提供水肥，这在瓜叶菊、多花报春、天竺葵、矮牵牛、蒲包花中常应用。(二)无土栽培的装置无土栽培所需装置主要包括栽培容器、贮液容器、营养液输排管道和循环系统。1.栽培容器主要指栽培花卉的容器，常见有塑料钵、瓷钵、玻璃瓶、金属钵和瓦钵等。主要以容器壁不渗水为好。2.贮液容器包括营养液的配制和贮存用容器，常用塑料桶、木桶、搪瓷桶和混凝土池。容器的大小要根据栽培规模而定。3.营养液输排管道一般采用塑料管和镀锌水管。4.循环系统主要由水泵来控制，将配制好的营养液从贮液容器抽入，经过营养液输排管道，进入栽培容器。

阳台无土栽培蔬菜的方法：韭菜无土栽培新技术用深18--20厘米的花盆或木槽，装深1--2厘米的河南沙用水冲净，以防带菌。选用2年以上的露地韭菜根，剪去老根、叶留下短缩茎根，插栽到花盆中，3--4株为一撮，行距33厘米左右，栽扣浇透水1次，新根长出后，再浇营养液，一般每隔1天浇1次水，浇1次营养液，春、夏、秋每1--2天浇1次；冬天3--5天浇1次，阴雨天、下午、晚上不浇营养液。希望对你有所帮助。

你好，在阳台上种菜目前来说还是比较新潮的，但由于阳台是房屋建筑的一部分，本身承重能力是有限的，不可能承载像泥土那样大比重的物品，因此不能照搬传统的栽培方式，那样可能会超重而使使用不安全。提几点建议供参考：1、假如一时种菜热情高涨，那么不妨马上去买一些花盆，按种花的方式在阳台上摆放花盆，在花盆里种菜，这样所需泥土不多，重量阳台的结构是足以负荷的，没有危险。由于阳台背身的局限性，在阳台上种菜（或种花）和在地面栽培是完全不一样的，假如你细心管理，一样可以获得“丰收”的。具体“图样”，在阳台上栽培其实并无一定，完全可以按照自己喜欢的样式摆放、布置。通过在花盆里试种，获得一些初步经验之后，若“种菜”热情依然不减，则可以继续以下。2、使用“膨胀珍珠岩”配合花草有机肥等重量较轻的材料，代替泥土，可以大幅度的减轻重量，这样你就可以像田间栽培一样，随意布置你的“菜圃”了，当然这样的投入也是比较大的。3、若你的确是真心热爱栽培园艺，那么你最应该采用的是“无土栽培技术”了，当然这投入就更多了，并且设计一些专业技术，但这个技术可以实现“立体栽培”，最大限度的增加你的种植面积，甚至可以将阳台附加的墙面也利用起来，“无土栽培技术”所涉及的技术及要求，在网上及相关书籍中都可以找到。祝你“种菜”成功！

你好！用疏松的壤土，在播种的时候加些有机肥就好；如果阳台面积小，可以不要土，直接弄托盘，做无土栽培就好。希望能帮到你！
