Exploration of Chemical Dwarfing Technology for Crops

Modern cities are full of high-rise buildings, and the old courtyard-style single-story homes have become towering skyscrapers. The living environment has changed, space has become smaller. In the past, people loved to use large potted plants and tallorchids, but now they are gradually turning to favor dwarf varieties. At present, among Chinese orchids, whether "flower orchids" or "art orchids," their short dwarf varieties are very popular. Many people at home and abroad greatly appreciate the "dwarf orchids" with sturdy, short plant shapes and broad, thick leaves. What are the characteristics of dwarf orchids Dwarf orchids were fully developed in Taiwan, China. In 1987, the rare dwarf orchid "Danxia Orchid" was discovered in Danxia Mountain, Guangdong. In 1973, the rare dwarf "Damo Orchid" found at the Damo Temple in Taiwan, China, and another precious dwarf "Guanyin Orchid" produced in Miaoli, Taiwan, China over a decade ago are all treasures among famous varieties. They are currently the most expensiveorchidsin the world. In Taiwan, China and Hong Kong, China, each plant has been priced at over a million Hong Kong dollars. The characteristics of dwarf orchids are short plant shape (generally considered to be no more than 20 cm in height), broad and thick leaves, dark green leaf color, shorter leaf stalks, and obvious bulbs (pseudobulbs). Leaf tips are mostly bluntly round or shield-round or resemble a fruit-head round. Famous dwarf orchid varieties mostly feature dwarf plus strange flowers and strange leaves, or all three qualities of dwarf, strange, and artistic. Strange leaves refer to leaves that are particularly thick and twisted, with contracted leaf tip edges making the orchid leaves spoon-shaped, with vertical or horizontal wrinkles and folds on the leaf surface, uneven in height, some resembling toad skin, and some with uneven but smooth leaf surfaces. At present, dwarf orchids include Baosui Orchid,Four SeasonsOrchidand Qiuhui, etc., with the Baosui dwarf orchid being the most precious. Due to market demand for dwarf orchids and the attraction of increasingly higher prices, how to cultivate dwarf orchids cannot help but arouse the interest oforchid growersand flower industry professionals. There are three approaches: first, seeking and discovering new treasures and ordinary varieties from wild resources; second, researching rapid propagation methods from existing famous dwarf orchid varieties; third, selecting medium-dwarf ones with broad, thick leaves from "home orchids" or "falling-mountain orchids" and using scientific methods and chemical agents for dwarfing. Chemical Agent Dwarfing Experiment The chemist of Red Green Flower Fertilizer and other series products, at the Rose Garden Flower and Tree Farm in Shantou City, with the assistance of its horticultural technician, following the successful experiment of using Red Green Flower Fertilizer soilless new method tocultivateChinese orchids, began in March 1991 to undertakeorchiddwarfing research and experimentation work. After scientific experimentation, comparison, and screening, an effective "Dwarf Orchid Agent" formula and method were finally found that inhibits orchid leaf elongation, turns leaf color dark green, and makes the plant shape shorter. This formula contains dwarf orchid medicine and nutrients needed for dwarf plant growth. Its solution is sprayed on new leaf buds and the whole plant, once every 10-15 days. After four months of spraying on Baosui Orchid, initial results were seen. Compared with orchids of the same batch, the height difference was obvious. Among 25 test plants, only two exceeded 20 cm in height, and the rest were shorter than 20 cm. The dwarfing effective rate reached 92%, the leaves also became thicker and harder, and bulbs clearly formed. Orchid growers in Chaoshan gave play to their intelligence and talent, successfully creating the "Dwarf Orchid Agent" and filling a gap in the domestic and Hong Kong, China markets. Because it is also suitable for dwarfing ordinary flowers and plants, it was named "Red Green Flower and Plant Dwarfing Agent." It must be pointed out: most scientific creations and inventions still require continuous improvement, supplementation, and enhancement in use or practice. The same is true of the Dwarf Orchid Agent. It works best when used for soillessOrchid growersused their ingenuity and successfully created a "dwarfing agent for orchids," filling a gap in the domestic and Hong Kong, China markets. Because it is also suitable for dwarfing ordinary flowers and plants, it was named "Red and Green Flower and Plant Dwarfing Agent." It must be pointed out: most scientific creations and inventions still require continuous improvement, supplementation and enhancement during use or practice, and the dwarfing agent for orchids is the same. When used for soillesscultivation. As for the dwarfing treatment method, besides the above-mentioned use of solution sprayed on new leaf buds, the method of soaking orchid heads can also be used. Besides being sprayed on green-leaf varieties, if sprayed on line-art orchids, some can produce line-art dwarf orchids.
