Matters needing attention in fertilization of Orchid

There should be some difference between growing flowers now and growing flowers a few years ago. At present, the new suites in rural and urban areas are decorated in style, and the potted flowers add atmosphere and splendor to the indoor and outdoor. Flowerpots, plant materials and fertilizers should meet the hygiene requirements. We do not advocate the use of organic fertilizers, such as various cakes, fish scraps, hair, etc., unless these substances are very rotten, it is best not to use them. According to years of experience, it is easy to use these organic fertilizers to attract ants, earthworms and centipedes. If it rains for days, it may also attract races and snails, and it is also prone to mites, which is not only harmful to orchids, but also harmful to health and unsightly. We advocate the use of special fertilizer for orchids. This kind of fertilizer comes with detailed instructions and is easy to master. Some formulations of compound fertilizers used in rural areas are not accurate, and some instructions are not clear, so they are not suitable for use.

We introduce several commonly used and cheaper orchid special fertilizers for orchid friends' reference.

The "Orchid King" produced by Chengdu Huayi Science and Technology Development Company in Sichuan Province is an ideal synthetic liquid fertilizer with moderate price and can promote root growth and growth of strong grass. it is an orchid special fertilizer approved by Mr. Wu Yingxiang after inspection. It is easy to use and has no peculiar smell. It is a kind of harmless fertilizer. After several years of trial, Chun and Xialan use this fertilizer with high emergence rate, good growth and no side effects. According to the instructions, the fertilizer can be used once in 7-10 days in spring, summer and autumn, and it can also be used on sunny days in winter, which is beneficial and harmless. You can add eight jin of water to a bottle according to the regulations, or even talk about it.

Huabao 1Mel No. 5 made in Taiwan is a kind of powder fertilizer. Different serial fertilizers are used according to orchid varieties and different growth and flowering stages, and the price is acceptable.

If it is a 50Mel 60 pot Xiaolan nursery, you can still buy some hormone fertilizers such as root promotion, bud promotion, flower promotion (boric acid is available). However, these fertilizers are more expensive, but when used in famous products, they can get better results. If you use hormone drugs, do not use too much, otherwise orchids grow too fast and are vulnerable to virus damage, resulting in losses. If you find that there is a virus attack, you should immediately stop the application, gradually increase the light, increase the application of phosphorus and potassium fertilizer, and be isolated from the healthy grass.

Bone powder was applied to tall bluegrass to increase phosphorus and potassium fertilizer and a small amount of trace elements such as calcium, magnesium, zinc and iron. Bone meal fertilizer, should buy rubber refinery production, soil factory production of bone meal fertilizer has a bad smell, should not be used. After making glue, the bone powder particles are very fine, which can be sowed on the basin, and can be slowly infiltrated and absorbed by the roots with watering, which is purely a kind of harmless fertilizer.

Potassium dihydrogen phosphate should always be prepared, such as "blue fungus king" fertilization, once every two times to add phosphorus dipotassium, bluegrass will grow strong, but also easy to sprout flower buds. The application of phosphorus dipotassium is very convenient, with 1/1000 liquid, it can spray leaves and irrigate roots, and the fertilizer effect is both fast and good. The use of phosphorus and potassium is beneficial to orchids but not harmful to orchids. After years of observation, it is economical and affordable.

Fertilizer is available all the year round, and nitrogen fertilizer should be applied before the spring orchid is pulled out of the scape, so that the flower pavilion will grow taller and the flowers will bloom. Petal flowers can not lack potassium, only use nitrogen fertilizer, water is not buckled, flowers may have long feet. If potassium and trace elements are sufficient and water is deducted in time, petal-shaped flowers like copper money can be produced.

After the flowers are cut off, orchid should be transferred to normal fertilizer. Can try the market imported sprouting agent, rooting agent, once every seven days, take turns with light fertilizer spray leaf irrigation basin. Until the new seedlings take root and then transfer to the use of normal fertilizer.

After the beginning of autumn, the weather turns cool, and the leaves take turns to apply phosphorus and potassium fertilizer and imported flower-promoting fertilizer, so that Lanhui can send more winter buds and blossom normally next spring. In addition, we must pay attention to the timely application of heat-proof fertilizer and cold-proof fertilizer. Two or three days before the arrival of high temperature in midsummer, phosphate and potassium mixed fertilizer can be applied once depending on the weather; summer days can be regarded as a cycle of about ten days, and phosphate and potassium fertilizer can be applied immediately if it turns cool and intermittent (such as rainy and typhoon days). Cold-proof fertilizer had better be added with some bone meal when it turns over in autumn. Phosphorus and potassium fertilizer should be applied a week before freezing to make bluegrass more hardy. Sick and weak seedlings should be isolated and placed in a safe place. Heavy fertilizer will kill them. (Guan Wenchang, Zhu Hexing)
