Although the temperature has fallen, but the early autumn weather is still hot and hot, the autumn tiger is very powerful, this time do not remove the sunscreen, once the sunburn can not be saved.
Lighting techniques
At noon in early autumn, we need shade and sun protection. Sooner or later, we can move the orchid out of the room to receive full sunlight. In addition, we can increase the temperature difference and promote the flower bud!
1. Typhoon prevention
Early autumn is a season of frequent typhoons. We should be prepared for prevention. We should check whether the sunshade, ceiling and doors and windows are firm for outdoor orchid cultivation. We should close the doors and windows in time for indoor orchid cultivation.
2. Prevent rainstorm
Generally, typhoon transit will be accompanied by rainstorm. Orchids on the balcony will be moved into the room in time. Outdoor maintenance can be directly covered with sunshade, which can effectively buffer the rain, and can also be breathable and permeable, which is conducive to the growth of orchids.
Heavy rain, the sun will be very dry, at this time must be more ventilation, more ventilation, otherwise the soil is stuffy and hot, up and down steam boil, orchids are easy to rot.
When the temperature drops below 30 ℃, fertilization can be considered, and proper fertilization can blossom well
Fertilization techniques
1. Spray P and K Fertilizer on the leaf, or embed organic fertilizer, rotten sheep manure, pigeon manure, etc. in the plant material, and keep away from the root.
2. The principle of fertilization is to apply thin fertilizer frequently. It can be applied once every 10 days in early autumn.
Autumn wind, dust fly, autumn climate is mainly dry, with clay pot and large particles of planting materials orchid, basin surface is very easy to dry, to timely make up water, prevent leaves from drying.
Watering techniques
1, watering to see dry and wet, once poured, spray water spray sooner or later, increasing air humidity.
2. For the robust orchid, it can control the water and accelerate the flowering properly from August to September, and then water when the leaves are about to wilt.
Note: use cinnabar flower pot or plastic flower pot to cultivate orchid, to prevent the soil from getting too wet and eating hot rotten roots, especially in the case of fine plant materials and poor air permeability, open more windows and ventilate after each pouring.
Early autumn is the season of high incidence of orchid diseases and insect pests, such as anthrax, erysipelas, scale insects, black spot, etc., which are more powerful than that in midsummer. Once infected, the whole plant will rot if it is scorched and blackened.
Once it is found, it is necessary to cut off and burn the diseased leaves immediately. During the onset period, Bordeaux solution or 1000 times diluted methyltobuzin solution shall be sprayed on the leaves every other week, and windows shall be opened for ventilation and weeds shall be cleaned.
