Soilless cultivation is a new type of cultivation method, which is low in cost and convenient. The cultivated products are all natural and pollution-free green foods, and the economic benefits are very good. Today, Xiaobian teaches you how to choose soilless culture substrate! Every grower follows the Xiaonong.com! Substrate cultivation is the most natural way of root environment in soilless culture. It has better buffering capacity and there is no problem of imbalance between nutrients, water and oxygen. Compared with hydroponic culture, The management is more convenient, the one-time investment is less, the cost is lower, the performance is stable, and the economic benefit is good. It is most commonly used in actual production and is the easiest to promote. Soilless culture consists of nutrient solution, substrate, equipment and facilities. After years of development, nutrient solution formula and maturity, facilities and equipment have become a complete system. The matrix needs to be adapted to local conditions in different regions and different environmental climatic conditions, and different substrates are used for production. Here are some of the issues you should be aware of when selecting a matrix. 1. In the rapid development of human civilization, people realize that the development of the environment as a sacrifice is not advisable. For the choice of the substrate, it does not pollute the environment, and the recycling is more and more valued. This is also the future. The trend of development. The earliest popular substrates are rock wool and peat, but these two substrates are not only costly but also non-renewable resources. Long-term mining not only depletes resources, but also destroys ecology and landforms. Nowadays, the world is replacing the matrix of rock wool and peat, and the low-cost and environmentally-friendly matrix is ​​the focus of soilless culture research in China. Of course, a matrix cannot be suitable for all regions. Different climates, resources and other issues make the requirements of the matrix different in each region. After all, the increased cost of long-distance transportation substrates may not be fully applicable. 2, the ideal matrix The performance requirements of the matrix are mainly reflected in the coordination of water, fertilizer and gas. It must have good water retention capacity, gas permeability, fertilizer retention, buffer capacity for acid and alkali, and economical and practical. Can be taken locally. The ideal soilless culture substrate should have better performance than soil, suitable for plant growth at a later stage, small bulk density, large potted plants can also be easily moved, and the load on roof cultivation can be reduced. The porosity is large, and the substrate is still saturated. There is a large amount of air in the crevices, and the water holding type is strong, and it is not necessary to frequently water. It does not affect the growth of the roots of the crops, but also prevents lodging. When there is little water, it will not crack and break the roots of the crops. It has certain heat insulation capacity. It does not carry pests and diseases, can be reused and disinfected, and will not deteriorate due to high temperature and other factors. It has a certain fertility, does not react with pesticides, does not affect the familiarity of nutrient solution, has no special taste, is not suitable for attracting animals, does not pollute the soil, is easy to clean, can be mass-produced, simple management, and low price. The choice of soilless culture substrate is very important, because the substrate determines the growth of cultivated vegetables, so the selection method of the above soilless culture substrate is quickly collected!
