The plant material of Hanlan

In order to cultivate pure cold orchid, in addition to creating superior ecological conditions such as light and air humidity, plant material is the foundation and water management is the key. The selection and proportion of plant materials should take into account not only the characteristics of looseness and permeability, but also moist but not stained. In but not dry, drainage and water retention of moderate performance. There are many kinds of plants that can be used to cultivate orchids, all of which have their own advantages and disadvantages, so we should promote their advantages and avoid their disadvantages. In order to find the mixed formula of plant material suitable for the cultivation of pure cold orchid, the author has made a variety of experiments, including the lessons of failure and the joy of success. The author once stuffed several pots of pure cold orchid trees from different producing areas with snake wood, and then filled them with mixed plant materials. after one year of cultivation, it was observed that all the new roots did not grow and the old roots were empty. The reason is that the snake wood drains too fast, the basin soil is easy to dry, and if it is too dry, the root is dehydrated, and the hollow root (hollow root) is formed for a long time. After years of exploration, the author found that it is effective to cultivate pure cold orchid with the following two kinds of mixed plants.

Formula 1: Lentinus edodes soil 50%, husk charcoal 30%, coarse river sand 20%, plus 10% dried cow dung and 10% bone charcoal.

(this formula is also suitable for the cultivation of Cymbidium)

Formula 2: char 40%, Lentinus edodes 20%, red brick 20%, coarse river sand 10%, dried cow dung 10%, plus bone charcoal 10%.

(this formula is also suitable for the cultivation of Yelan)

Lentinus edodes soil, that is, the waste material for cultivating Lentinus edodes strains, contains nutrients, loose and breathable, which is conducive to root expansion. With its planting orchid, orchid leaves are easy to produce snakeskin art.

Dry cow dung, water and ventilation, long-lasting fertilizer effect. Cow dung is superior to cow dung that eats dry feed in winter, because after ruminating hay, the plant fiber is fine, but it is still elastic and contains certain nutrients. This kind of cow dung is soft and fat, which is very suitable for Langen's good habits.

Rice husk charcoal is an unburned but black rice chaff. It is rich in potassium, so it is beneficial to loosen the soil and improve the soil temperature.

Bone charcoal, rich in phosphate fertilizer, fertilizer is not violent, fertilizer effect is lasting, can make the soil loose, but also conducive to artistic change.

The above several kinds of plant materials are available all over the country, which are convenient to be obtained and low in cost. In different seasons, different weather and different growth stages of orchid plants, orchid bacteria have different requirements for dry and wet soil (plant material), which can be solved by different water management. Generally speaking, it should be moist in spring, wet in summer and autumn, and dry in winter.

Pure cold orchid is not easy to raise, pure vegetarian cold orchid is even more difficult to raise. At present, pure vegetarian cold orchid is extremely scarce, and pure vegetarian cold orchid is favored by people. Pure vegetarian cold orchid has a false vegetarian heart, the flower is blooming, the whole flower is pure, very similar to the whole vegetarian, and the tongue can appear variegated spots within three days of blooming. Pure vegetarian heart cold orchid generally does not appear color spots on the tongue three days after blooming. Lanyou should pay special attention to this when buying pure vegetarian cold orchids, otherwise they may have to pay tuition fees.
