Cultivation and Management of Phalaenopsis
Commentary: Phalaenopsis is a kind of orchid, which gets its name because of its petal situation. As a flower variety with high ornamental value, Phalaenopsis has been cultivated all over the world. The cultivation of Phalaenopsis in greenhouse is mainly about the management of temperature, humidity and light.
Guilin (technician from the Flower Research Office, Institute of Horticulture, Shanxi Academy of Agricultural Sciences): Phalaenopsis is known as the queen of foreign orchids, usually with high temperature requirements, most of which are controlled between 15 and 35 degrees. In greenhouse cultivation, the temperature needs to be increased in winter and soil heating is needed. In the family, there is no need for additional heating, most of them are about 15 degrees, and its lighting requirements are relatively poor. So when growing in the greenhouse, we need to use 80% of the shade net for shade, in the family, do not put on the balcony for exposure, the humidity requirement is 60% to 80%.
Commentary: in terms of maintaining humidity, it is mainly timely watering, but because Phalaenopsis is mainly ornamental, we should pay attention to protect the petals from damage when watering.
Gao Guilin (technician from the Flower Research Office, Institute of Horticulture, Shanxi Academy of Agricultural Sciences): so we should pay attention to the daily management, more spray, less watering, spray should be sprayed on the leaf, do not spray on the petals, so that the petals are easy to wither.
Explanation: when Phalaenopsis is cultivated in greenhouse, due to the limitation of the place, the cultivation density is high, and it is easy to breed some diseases and affect the growth of Phalaenopsis. Therefore, growers should understand the prevention and control measures for these diseases. Guilin (technician of Flower Research Office, Institute of Horticulture, Shanxi Academy of Agricultural Sciences): the diseases of Phalaenopsis are mainly white 1000 disease and blackhead disease. Our daily control is mainly used alternately with chlorothalonil and carbendazim. The control was carried out by spraying between 7 days and 10 days, from 10:00 to 12:00 every morning.
Commentary: the above two kinds of drugs are used alternately in order to avoid drug resistance in Phalaenopsis and affect prevention and control. Growers must pay attention to it. These diseases of Phalaenopsis are relatively hidden at the initial stage of the disease, and generally begin to propagate and spread from the leaves, so in order to control the spread of these diseases on a large scale, managers should observe them in time in their usual management. if necessary, you also need to open the back of the leaves and petals and examine them carefully.
Guilin (technician of Flower Research Office, Institute of Horticulture, Shanxi Academy of Agricultural Sciences): with the improvement of Phalaenopsis cultivation technology and the increasing demand for Phalaenopsis, Phalaenopsis flower has increasingly become a fashionable flower. Phalaenopsis has become a good project in the flower world, and the market prospect is broad.
Commentary: although Phalaenopsis is popular in the flower industry, as a grower, we must choose and develop according to our own situation and under the premise of mastering the relevant technology and fully understanding the market situation.

Treatment of rotten roots of Phalaenopsis at home
Sometimes improper watering or poor soil matrix will lead to rotting roots in Phalaenopsis in the family. Here are the measures to prevent and cure the rotting roots. First of all, the selection of basin soil, to choose loose, aerated, permeable matrix. Such as peat mixed with perlite, peat mixed with pine needles, moss and so on. Use organic fertilizer as base fertilizer. The second is to keep the basin soil moist, but not stagnant water, which is the main reason for rotting roots. It should be observed that after watering, the soil can not seep down for a long time, indicating that the basin soil has been used for a long time and its density has increased, so the soil should be changed quickly.

Cultivation measures of Phalaenopsis
Phalaenopsis is a high-grade flower welcomed by consumers. It has beautiful flowers, bright colors, elegant temperament, long viewing period, low requirements for cultivation and management. Family cultivation can still blossom next year as long as it is managed properly. And you can regulate the florescence to the day you need. Phalaenopsis originates between 23 degrees south latitude and 23 degrees north latitude, and more than half of Guangdong Province is within this range, so Guangdong has the climatic environment of cultivating Phalaenopsis, with fast growth and short production cycle. Most varieties can be cultivated in 16 months.
