1, planting time: planting dendrobium time is generally in spring and fall, and more in the spring. Take Zhejiang as an example, the best time to plant is in April-June every year, when the temperature is between 15-25℃, the air humidity is also relatively large, the survival rate after planting is high. If it is planted in the fall, generally wait until mid-September to late October, and also to do a good job of preventing cold and anti-freezing.
2, substrate production: want to plant dendrobium, be sure to prepare a good substrate. Good water retention is essential, but also ventilation and air permeability. Generally water moss, gravel, peanut shells, moss, coconut bark, pine bark, wood shavings and so on for preparation, commonly used bark and wood shavings, and mix it with gravel, organic fertilizer can be. It should be noted that the bark must be crushed into particles, the length of which does not exceed 3 centimeters.
3, environmental requirements: if planted in the greenhouse, be sure to ensure good ventilation before planting, but also shade and rain, and can block the pests. Temperature should be controlled between 15-30 ℃, the hotter places to use 80% of the shade net cover, but also pay attention to cooling. Colder ones will need less shade and insulation with double layers of plastic film.
4, planting: dendrobium planting is divided into three kinds, respectively, tree planting, stone planting and humus cultivation. Tree planting to choose thicker bark, high moisture tree species as the main attachment, common yellow kudzu tree, camphor tree and pear tree. For stone planting, use rough stones with humus and moss on the surface. Duplicate soil cultivation should be prepared box, the substrate will be poured into the planting.
Second, how to raise1, light and temperature: Dendrobium is suitable for growing in the environment of 15-30 ℃, if the temperature is high, we must ventilate in time to reduce the temperature, and lower to keep warm. It itself does not like light, so pay attention to shade, avoid being irradiated by strong light.
2, water and humidity: Dendrobium likes humidity, watering to control the amount of water, to ensure that the moisture content of the substrate is not more than 70%, nor less than 60%. The air humidity should be kept at about 90%, and can be appropriately reduced after rooting, but should also be kept above 70%.
3, summer and winter: summer high temperature and winter low temperature, do not let the substrate too wet, usually between 30% -50% is appropriate. In addition, winter should be a good insulation measures, you can advance frost resistance exercise, spray water every two weeks.
Common greenhouse heating methods include hot water heating, hot air heating, electric heating, brewing heating, covering with straw mats, thermal insulation quilt, ad
