从去年起,我们对碗莲进行了无土栽培试验,取得了很好的效果。现介绍如下: 1.基质与营养液基质采用筛过的纯净粗沙,粗沙不仅通气,而且较重,有利于固定藕身。把基质高温清毒后,装入口径25—30厘米、高20—25厘米、内外光滑无底孔的干净瓷盆中。营养液的配制可参见本刊1987年第7期朱士吾的配方。碗莲最适宜的pH值为6.5～7.0,若过低或过高,可用酸或碱来调整。 2.种藕的栽植栽种前先用适量的水把基质拌潮,然后将带顶
Since last year, we carried out soilless cultivation experiments on bowl lotus and achieved good results. Now introduced as follows: 1 matrix and nutrient solution matrix sieve with pure coarse coarse sand, not only aerated, but also heavier, is conducive to the fixed lotus body. The substrate after high temperature detoxification, into the diameter of 25-30 cm, 20-25 cm high, smooth inside and outside the hole without a clean porcelain basin. The formulation of nutrient solution can be found in our magazine No. 7, 1987 Zhu Shiyu formula. Bowl of the most appropriate pH value of 6.5 to 7.0, if too low or too high, can be used to adjust acid or alkali. 2 kind of lotus root planted before planting with the right amount of water to mix the substrate tide, and then top
