< b > Common maintenance methods of Cymbidium, Jian Orchid and Magnolia (figure) < / b >

1, light control cooling Cymbidium growth is suitable for the annual average temperature between 15-23℃, summer temperature is hot, with 70-80% plastic shading net to cool down.

2, high temperature to promote the drop due to excessive light caused by high temperature, should take to increase the shade level and density to promote cooling; summer and autumn season has strong light, hot air, high temperature, should open doors and windows, let the blue field air convection thoroughly, promote cooling. Spray clean water under the channel and orchid rack, spray water mist into the indoor space, also promote cooling temperature, spray new lipid film, not afraid of sun exposure evaporation, can adjust water absorption, drought prevention and rain prevention.

3, moisturizing ventilation orchid field moisturizing and ventilation to adjust to a most reasonable state, in order to facilitate orchid growth. To maintain air humidity to use advanced automatic humidifier can also be to space, channels, blue frame spray water mist. The humidity of the substrate should be adjusted according to the conditions of light, humidity and ventilation. Soil cultivation with 2-4 days to irrigate 1 water, adhere to the "rather dry not wet", watering time limit should be adapted to local conditions. Wild orchids are native to the mountains and valleys, and their habitat is open on all sides, but they are shaded by trees and grass, and there is a breeze from time to time. They can grow in a fresh air environment for a long time. Therefore, orchids should also create conditions for these orchids to grow, and more closed orchids should open doors and windows to promote air convection.

4, insulation antifreeze: Jianlan can only withstand transient, intermittent-2 to-5℃ low temperature under the protective conditions of shielding frost, so it should be insulated in winter greenhouse, and heating equipment can be adopted if conditions permit. 5. Fertilization shall be carried out according to the blue, depending on the seedlings, fertilizer, light rather than thick, and timely thin application. According to orchid seed, seedling potential, physiological characteristics, grasp the timing. Dry fertilizer: cattle bone powder (containing 4% nitrogen, 22.06% phosphorus), plant ash (1.04% phosphorus, 6.41% potassium), cake fertilizer (7% nitrogen, 1.32% phosphorus, 2.12% potassium) and burned soil mixed fertilizer and compound fertilizer alternately used not less than 4 times a year in the basin. The liquid fertilizer is filtered and diluted by decomposed organic matter fertilizer, urea, potassium dihydrogen phosphate or special flower fertilizer are alternately applied as topdressing or fertilizer outside the root, generally once every 15 days, and the leaf surface is sprayed with clean water two days before and after spraying outside the root to wash dust and liquid residue.

Fertilization time:

① Germination fertilizer (late spring and early summer): dry fertilizer once or twice, fertilizer outside the root once every 10 days, mainly nitrogen and potassium fertilizer, promote the shoot of the aboveground part and the root system expansion of the underground part.

② Development fertilizer (late summer and early autumn): The leaves of new buds extend and leave, promote the new buds to be strong, mainly nitrogen, frequently apply thin fertilizer, promote the strong seedlings after the new buds open leaves, spray once a week with potassium dinitrate, spray Zhuanggan Ling, can make the plant stems thick, leaves thick, leaves fresh, plants lush.

(3) Fertilizer for promoting flowers: When the leaves of new shoots no longer grow, they will enter the flower bud differentiation stage, mainly phosphorus, dry fertilizer twice, fertilizer outside the root once a week, spraying flower Zhuangdiling can promote strong flower buds, plump petals, gorgeous flowers, rich flowers and prolong flowering period.

④ In late autumn and early winter, orchids will turn into dormancy period from cold dew to early winter. Dry fertilizer will be applied once, liquid fertilizer will be applied twice, and foliar spraying will be carried out once every 10 days to ensure safe overwintering, cream breeding, and increase germination rate in spring.
