1. Can

In theory, it is possible. Generally, as long as the growth of the plant meets the requirements of light, water, nutrients and other substances, it can survive. Here's a question. Can sand feed plants because it's just pure particles and doesn't contain any nutrients

2. Cause

Generally, this kind of plant culture using sand as the substrate without any soil substrate is called soilless culture. In this way, water and sand without bacteria are used instead of soil as the growth substrate of plants. Mix inorganic fertilizer into it as plant nutrients

3. Advantages

This method can effectively avoid diseases and pests caused by soil pollution; The inorganic fertilizer added inside has no taste, will not breed mosquitoes, and is very clean and hygienic. The bowl lotus planted in this way has thick green leaves, many and large flowers, beautiful colors and long flowering period

4. How to raise

(1) Suitable utensils are needed for soilless planting. Generally, a round glass tank for goldfish is used, and then a layer of opaque black paper or black cloth is wrapped on the outside of the tank, and finally a layer of white paper is wrapped. This is a way to keep dark, which can not only avoid the propagation of algae by nutrient liquid under light, but also help to prevent the underground stem of the plant from turning green and affecting the blooming of flowers. If you don't want to be so troublesome, you can buy porcelain pots or purple sand pots directly

(2) The type of sand can choose coarse sand, which is mainly used to fix the position of lotus root. When planting, first place the lotus root horizontally on the surface of the sand, and then put some sand on it to cover the whole lotus root. It is worth noting that the tail of lotus root must be tilted upward. Finally, slowly pour water into the basin

(3) Because the lotus root itself has nutrition, it will sprout and sprout seedlings by itself, grow stems, and then grow leaves

(4) However, because the nutrition of lotus root will be consumed sooner or later, we should add some nutrient solution rich in elements once a week
