New medium of orchid [volcanic rock]

In recent years, with the acceleration of orchid cultivation industrialization, the standardization of orchid plant material has also been put forward. In this process, the main trend is granulation, and there are many varieties in the field of granular orchid plant material, each of which has its own advantages and disadvantages.

According to my half-year observation and trial, there is a supply of pumice in Zhejiang market-the bottom stone and blue stone processed by volcanic stone, which are very suitable for batch cultivation and trial. The bottom stone diameter is I5-30mm, and the blue stone diameter is 7-15mm. The bottom stone can be taken and used immediately, and the blue stone can not only be cut directly on the basin, but also be mixed with Emei immortal soil, peat particles, broken tiles and so on. I am the proportion of volcanic stone and immortal soil on the basin, the method is to sift out the crushed powder (for other flowers), and then mix the particles and volcanic stone evenly, spread the bottom stone below, you can plant bluegrass. The first time the water needs to be watered thoroughly, in general, in order to increase environmental humidity, and then often in the basin grass and basin surface can be drenched. More than 300 orchids have grown well after half a year's trial.

According to the manufacturer Wu Jianmin. Its physical performance is excellent, that is, it is light and not easy to be loosely crushed, so there is no danger of blocking in the basin. The results showed that the bulk density of particles was 0.459mi 0.65, bulk density kg/m3240-450,7l.8-81%, compressive strength MPaO.53-1.76, water absorption 26.6 ml 64.2%, thermal conductivity Whamm.kjue 0.23mer 0.46. All of them are better than ordinary stone materials, especially the pores are smooth, that is, absorbing water without waterlogging, which can ensure a higher balance rate of water and gas in the basin. In addition to nitrogen deficiency, there is almost no shortage of major elements and rare elements such as silicon, iron, calcium, phosphorus, potassium, sodium and so on. When used alone. If nitrogen is added in time, bluegrass can grow normally, and if it cooperates with fairy soil and peat, it can complement each other. It is a good medium that is beneficial and rare.

Volcanic stone is a mineral rich in domestic resources. The utility model has a wide range of sources, easy to process, easy to use and very sanitary. I think it will soon be adopted by orchid entrepreneurs and the majority of orchid friends, and it will also have an impact on the standardization and industrialization of orchid cultivation.
