Flowering Regulation and industrialization Technology of Dendrobium

The main contents are as follows: 1. this technology is applied to the florescence regulation and large-scale production of Dendrobium potted and cut flowers. Among them, the flowering regulation technology is the core technology, which makes use of providing good nutritional reserves during the vegetative growth period, promoting vegetative growth and delaying reproductive growth. After the first flower bud of Dendrobium grows, according to the climate of the year and the specific conditions during the Spring Festival, determine the time to erase the flower bud, and then use temperature control and fertilizer and water to promote the secondary growth of flower buds to achieve the goal that half of the whole inflorescence blossoms during the Spring Festival. In addition, the problems of light, temperature, humidity, cultivation substrate, diseases and insect pests in the process of industrial cultivation of Dendrobium were studied, and a complete set of industrial production management technology was summarized. Through this technology, 300000 tissue culture seedlings have been produced and more than 50, 000 potted flowers have been produced, reaching a certain industrialization scale.

The equipment invested are: for ordinary growers, a simple plastic film greenhouse can be selected in areas where there is no frost all the year round; for growers who target the flowering period of the Spring Festival, it is necessary to be equipped with a water curtain fan cooling system and a sun shading system of 60% and 70%, so that the greenhouse has good ventilation and cooling in summer and good heat preservation in winter. The growth and development of Dendrobium generally requires higher temperature throughout the year, while the Pearl River Delta is located at the junction of tropical and subtropical zones, which has the natural conditions for large-scale production of Dendrobium, and there are many low-cost substrates suitable for cultivation. the consumption of all kinds of resources is low. This technology can not only enhance the international competitiveness of China's high-grade flowers and plants, give full play to the advantages of thermal resources in Guangdong Province, but also open up a new way to earn foreign exchange through agricultural exports, and promote the large-scale and high efficiency of China's flower industry. produce very significant economic benefits.

2. Economic benefits of industrial production supported by this technology, according to the annual cost of 30, 000 plants per 667m2, the average price of each plant is 30 yuan, and the annual output value of potted flowers is 900000 yuan per 667m2, with a profit of ten thousand yuan a year excluding the cost. Fresh cut flowers produce 100000 pieces per 667m2. Calculated at 2.0-3.0 yuan per 667m2, the annual output value per 667m2 is 200000-300000 yuan. Excluding the cost, a profit of 150000-200000 yuan / year can be obtained.
