Conservation methods of orchids during their growth period

Let the orchids bask in the sun

More sunshine is good for promoting the growth of orchids, enhancing the resistance of orchids and safe wintering. Yellow and dull, the old leaves have no obvious change, the leaves are yellow and green, and the new shoots are not long. At this time, put the flowers out of the pot in a cool, ventilated place and wait for the soil to dry and then put it back into the basin. When lack of water, the tip or edge of the leaf withered and dried, the old leaf withered and fell off from bottom to top, and the growth of the new leaf was relatively normal.

Increase the humidity of the orchid room

Put the flowers out of the pot in a cool, ventilated place and wait for the soil to dry before putting them back into the basin. When lack of water, the tip or edge of the leaf withered and dried, the old leaf withered and fell off from bottom to top, and the growth of the new leaf was relatively normal.

(2) improper illumination. If the light is too strong, macula will appear in the sunrise part of the leaf, and the growth can be restored by moving to the shade, and there will be no macula in the new leaf. If the plant is placed in a shady environment for a long time, the leaves can not get enough light, which can easily lead to leaf yellowing or even shedding. Supplementary light can avoid the disease at this time.

(3) improper fertilization. Excessive fertilization or excessive concentration is easy to cause plant yellowing, showing brown at the tip of new leaves, generally thick but not glossy, concave and convex, old leaves are scorched yellow and fall off. At this time, fertilizer should be stopped immediately and the soil should be leached with serious water. Lack of fertilizer will also cause plant yellowing, but the lack of nutrients in the plant is different, showing different symptoms.

① nitrogen deficiency: simple yellow leaves, new leaves small and brittle.

② potassium deficiency: old leaves change from green to brown.

The plant material in the basin is easy to dry, so we should pay attention to increase the air humidity of the orchid room to prevent the withered tip of the orchid leaves. Areas with good air quality can be drenched in autumn rain, but should be sheltered in case of continuous rain. Do not let orchid plants be drenched in the rain for a long time to prevent waterlogged roots and orchid leaves from breeding black spot. Comprehensive fertilization to promote growth

In autumn, the temperature in most parts of China is appropriate, and the temperature difference between day and night is large, which is another golden season for orchid growth in a year, so it is necessary to carry out comprehensive fertilization according to the actual situation of orchid seedlings. More phosphorus and potassium fertilizer should be applied to robust orchid seedlings to enhance their ability to keep out the cold and lay a solid foundation for early germination and strong sprouting in the coming year; for orchids sprouting in autumn, organic fertilizer with full nutrients should be applied to meet the various nutrients needed for the growth of orchids. Urge it to grow strong before winter comes. But in principle, fertilization should be stopped at the end of the month. 6.1 weeding and loosening the soil

About a month after sowing, the seedlings basically came out. In order to prevent the growth of weeds and soil consolidation, the period of weeding and loosening soil is from April to October, usually 2-3 times a month. 6.2 Fertilizer and Water Management

Pay attention to extreme weather and prevent frost

If extreme weather occurs later this month, there may be early frost in the south of the Yangtze River, and the temperature in the temperate and high cold regions of the north will sometimes be below 0 ℃. Outdoor orchid farmers should pay attention to watch the weather forecast and do a good job of frost prevention and frost prevention at any time.

Thinning buds and promoting strength

This month, most buds of strong grass should be thinned in accordance with the principle of removing the weak and staying strong, all the buds issued by the old grass should be removed, and only the strongest buds issued by the former dragons should be left, and the rest should also be removed so that the flowers will bloom in the coming year. Combined with turning the pot, carry on the orchid trade.

Most of the orchid plants are mature, which is the best time to introduce varieties, turn pots, split plants and change materials in a year. If a full pot of mature orchid seedlings needs to be turned, this work had better be completed before the end of the month; if the new grass is not fully grown, it is best to postpone turning the pot to facilitate its continued growth until next spring. Introduction is the first step in orchid cultivation. It is crucial to make a good start and take a good step, but we must pay attention to the following problems. First, strict quality control, do not introduce sick seedlings. Lanyou needs to open his eyes when introducing and shut out the sick orchid in accordance with the principle of quality first. Orchid seedlings can be divided into strong grass, medium grass and weak grass, and there is a big difference in price. Skilled orchids can properly introduce small and medium-sized grasses, which can not only save money, but also improve their own skills; beginners of orchids had better introduce native species with strong adaptability to grow strong grass, although the price is high, but it is relatively easy to grow. The second is to strictly control the environment and improve the success rate. The environment of orchid cultivation must be considered in the introduction of orchids, which has a great influence on the success rate after introduction. Orchid friends with modern orchid cultivation facilities and superior conditions can boldly introduce greenhouse seedlings; orchid friends with simple facilities had better be introduced from orchid friends with similar orchid cultivation environment, and they have a greater chance of success. Generally speaking, the orchid raised by the introduction family balcony is the safest, the adaptability is the strongest and the success rate is the highest. The third is to close Lanyou strictly to ensure that the goods are authentic.
