Ventilation of orchid field and shade
The site should be as spacious as possible, and it should be high. The flower table can be made of bricks and stones. You can also put the empty flower pot with the bottom facing up and put the orchid pot on it, so that the orchid pot is 20 cm to 40 cm away from the ground. Especially in places with poor ventilation, the orchid pot should be put higher as far as possible. The shade should use bamboo curtain and bamboo fence, which is cheap, good quality and well ventilated p>
Orchid indoor ventilation
Buildings, enclosed plastic sheds or glass sheds, especially those heated by coal, should open windows or uncover films every day when the indoor temperature exceeds 10 ℃. In winter, when the temperature is high at noon, electric fans should also be used for directional exhaust in rooms closed on all sides p>
In the upper part of the greenhouse, the ventilation speed is relatively low, so the harmful gases should be eliminated completely in the upper part of the greenhouse. Pay attention to ventilation and water spraying at the same time, deal with the relationship between ventilation, heat preservation and moisture preservation, and prevent cold wind from blowing directly p>
The density of orchid pots placed indoors should be thin rather than dense. Sufficient distance should be maintained. If the section is narrow, the flower table can be built into a ladder shape. Attention should be paid to rinsing the surface of the orchid regularly, and to ensure that the pores are smooth. p>
Ventilation of orchid pot and pot soil
(1) The orchid basin should be a tile basin with high tube, high foot, thin wall and strong air permeability. The orchid basin with porous wall and bottom can also be selected p>
(2) The plant material or basin soil should adopt the layered method. If the basin soil is used, it can be covered with 2 to 3 small bricks at the bottom hole of the basin, paved with 3cm thick block charcoal, and then filled with the mixed soil of rotten humus soil and river sand. To 1 / 2 of the basin height, add a layer of 3cm thick burned slag, and then covered with mixed soil to the edge of the basin, so that the orchid basin has an environment in which gas can flow easily p>
(3) The number of plants planted in each pot should not be too large. If there are many plants and dense leaves, the pot should be turned over and planted separately in time, and the weeds, diseased leaves and dead leaves in the orchid pot should be removed frequently to facilitate ventilation< span>
