Ginger Nelumbo is a perennial herbaceous herbaceous flower native to Chiang Mai, Thailand. It has a strong, natural, hi-temperature, high-humidity, long-elliptic leaf, a pointed apex, and a purple mid-vein; 3-5 leaves can bloom. Spikes, the upper temporal lobe is a pink broad-ovoid sterile sepal, the lower is a honeycomb-shaped green sepals, containing purple and white flowers, flower posture, such as lotus. Because ginger lotus is a ginger plant, its pink sepal resembles a lotus flower and its name derives from it. At the same time, because of its native tropics, the flowers resemble a tulip and are also known as “tropical tulipsâ€. Jiang Hehua cut flowers for the production, per acre can be planted 1-1.7 million bulbs, each ball can be 3-5 long flowers, about 80 days after the species began to harvest, flowering from June to October, the whole growth period can produce flowers 5-8 million. (1) Variety selection - The varieties of ginger lotus flowers in foreign countries are quite abundant. There are different color varieties such as 'Chiang Mai Flour', 'Chiang Mai Red', 'Chiang Mai White', 'Chiang Mai Snow' and 'Blue Moon'. , and 'gem', 'rainbow' and other plant taller varieties, there are also some pot plants with shorter plants. In the country, cut-flower production is mostly made of pink 'Chiang Mai powder'. (B) the use of high quality bulbs - ginger lotus underground parts from the bulb and storage roots, the size of the bulb and how much the storage root, will directly affect the cut flower and bulb production, especially the early cut flower production. When planting, bulb diameter should be more than 1.5cm, and bulbs with 3 or more storage roots should be suitable. (III) Planting at the Right Time – The author made ginger lotus flower production in Dongguan, Guangdong Province in recent years, and learned more about Jiang Hehua's production in Dongguan. The suitable planting period in Dongguan is from the end of February to the beginning of April, and it is best to plant before the advent of the April rainy season. The soil is suitable for sandy loam soil. Before the planting, the soil shall be used to make hoeing. The width shall be 70-80cm, and the groove width shall be 20-30cm. For each row of 2 rows, the plant spacing is 7.5-12.5cm, and about 1000-17000 balls are planted per acre. After planting, the straw is covered with straw to moisturize, prevent weeds, and prevent rainwater from washing. The bunting sprays butachlor to prevent weeds from germinating prematurely. (D) fertilizer and water management - before planting per acre applied compound fertilizer (N, P, K content are 15%) 25kg as the base fertilizer, fertilizer every 10-15 days after germination, each applying 25kg of compound fertilizer per acre, fertilization The quantity and frequency of fertilization vary depending on the color of the leaf and the amount of color. The entire growth period of Jiang Hehua coincides with the rainy season. The time needed for real irrigation is small. It is mainly to pay attention to drainage and prevent flooding. When the soil is too dry, it should be properly watered to keep it moist. (5) Appropriate shading: Under the open-air cultivation of ginger lotus, the length of cut flowers is about 40-60cm, shading treatment can reach more than 70cm and can effectively reduce the green plaque at the end of the calyx, and the pre-growth rate can be 30. % Shade net moderate shade to increase the length of cut flowers, but in the dense plant growth should be timely removal of the shady net, otherwise it will easily lead to plant length, affect the quality of flowers. (6) Pest control - Pests mainly include moths, cockroaches, etc. Diseases include red spot and anthracnose. The pesticide was applied every 15 days or so, and pesticides such as methamidophos, dimehypo, carbendazim, thiophanate-methyl, and dexamethasone were sprayed in turn. At the same time, continuous cropping should be avoided and rotation with ginger crops should be avoided. (7) Harvesting and Transportation of Cut Flowers - When 3-5 smashing slivers are developed, it is appropriate to harvest ginger cut flowers. The correct method of harvesting and transportation is an important part of the success of Jiang Hehua's planting. The quality of ginger cut flowers is closely related to the amount of plant water content. Harvested in the early morning, cut flowers with high moisture content, the best harvest at 5-7, the longest vase life, after the harvest should be immediately inserted into the water to absorb water, after enough water, such as for 1 hour About short-distance transportation, the flowers in the transportation process can be waterless, but if it is a long-distance transportation, the fresh flowers need to carry water during the transportation to ensure the quality of the flowers. According to the above method, Jiang He vase is not a problem for 15 days. In addition, in order to increase the number of leaves reserved for the mother plants, in order to increase the yield of cut flowers and bulbs, only one leaf may be taken when the cut flowers are harvested.

Jiang Hehua is a new cut flower variety introduced in recent years. It is popular in the market for its advantages such as its warm lotus flower posture, up to 15 days of vase life, and clear, odor-free water after flower arrangement.
