Preparation method of Orchid mixture

In addition to high-grade orchids, magnolia, spring orchids, epiphytic orchids, etc., I use mixtures for four orchids and orchids, including peach red, silver needle iron bone, silver edge Dagong and so on. For the preparation of the mixture, I insist on about 50% of fresh Chinese fir shavings (that is, sawdust from electric planing when making furniture), pine, camphor wood and plywood sawdust can not be used, dry cow dung 10-15% (dried cow dung must be broken, not whole). The remaining 35% is made of coarse bran (husk), broken peanut shell, bagasse, broken brick powder, burned pond mud, coarse river sand, etc. A variety of mixtures are also available, then mix with a small amount of calcium superphosphate, and then sprinkle with human urine to dry for more than a month. I in addition to fresh Chinese fir shavings, dry cow dung about 60%, the rest casually mixed, the river sand can not be difficult to retting mellow, other materials must be difficult to retting mellow before using. This kind of orchid material is loose and fat, and there is no problem if it is not fertilized for half a year after planting. I piled up on the open-air rooftop, and once I found that the coarse sawdust of the woven bag was difficult to be fermented and dried, and it was very convenient for Lanyou to take it. However, the use of this orchid material had better be changed once a year, no more than two years at the latest. With this mixture, the blue basin noodles must be covered with a layer of broken bricks, which is both ventilated and beautiful. the broken bricks are ideally ancient green bricks, or old bricks, otherwise, the abandoned charcoal stove can be broken, which is a material that takes only a little effort and no money.
