Key Points and Methods of Rock Wool Cultivation Techniques Explained
Rock wool is made by melting limestone, coke, diabase and others together at high temperature and spraying them into fibers, then compressing them into blocks to form an inorganic solid substrate, with good air permeability and water retention, and is a very good soilless cultivation substrate, so what is rock wool cultivation technique?
I. What is rock wool cultivation technique?
Rock wool cultivation technique is planting plants in pre-made rock wool. This technique has low cost and good results, and suits conditions in China. The specific technique is to level the ground, compact the soil, then make a trough body with length, width and height of 10*100*20cm respectively, lay a layer of plastic film in the trough, then put the rock wool in, place some river sand or vermiculite, and plant the plants that need to be planted.
II. What are the characteristics of rock wool cultivation technique?
1. Non-toxic and sterile: rock wool is made under high temperature conditions, so it is completely sterilized, and does not contain pathogens or other organic matter.
2. Good for root growth: rock wool is formed by compression, and will not change shape when planting crops, and crop roots can easily penetrate into it; it not only has good air permeability, good water-holding performance, and a soft, uniform texture, which is good for crop root growth.
3. Recyclable: when using rock wool to cultivate plants, only drip irrigation of nutrient solution is needed, so after later crop planting it can be recycled.
4. Simple to operate: after rock wool is made, operation is very simple; just make the trough body well, place the rock wool, vermiculite or sand well, and insert the plants to be planted into the holes; this method is not limited by ground level, nor by power outages or water outages.
5. Can be used continuously: rock wool itself does not spread diseases, insects or weeds; when no serious disease occurs, it can be used continuously for 1-2 years or reused after disinfection.
