Due to its rich nutrition, no pollution, and more health care, edible flowers are favored by people. Planting methods also grow from the wild to the house behind the house, and even grow into pieces. The Institute introduced the demonstration of edible flowers and special vegetables in 2000, and has received significant economic benefits. Among them, the cultivation of hibiscus has created 1500kg of flowers for 667m2, and the net production value has exceeded 10,000 yuan. Hibiscus cauliflower is simple to make, can be cold, fried, soup, smooth and tender, delicious taste, fragrance, can run dry, Lee urine, in addition to damp heat. At the same time, it is also an important flowering shrub in summer and autumn, and it is one of the edible flowers worthy of promotion and cultivation. First, the characteristics of wood Hibiscus scientific name Hibiscus syriacusLinn. It is a perennial deciduous shrub of the genus Malvaceae which grows into a small tree in the south. Native to India and central China. The branches are more erect, the leaves are ovate, and the apex is trifid. There are three main veins, and the margins are serrated. Flowers are solitary in leafhoppers, with short stems, white in color, pale pink, pale purple, and purple in color. The flowers are bell-shaped, with single, double, and double petals. Capsule oval, mature seeds dark brown. For vegetable planting with pure white, pale pink, and preferably double petals. Muddy has strong adaptability to the environment, it is heat-resistant and cold-resistant, it is more resistant to dryness and barrenness, and it is not strict with the soil, especially the light and warm climate. Second, cultivation technology The land can be used as an open space behind the houses in front of the house, on hillsides, or on corners. It can also be planted on the vegetable fields and orchards and used as a hedge to beautify the environment and increase income. 2. Propagation methods The hibiscus can be propagated by seeds, but it can also be propagated by cutting. Generally, spring cultivars are used for propagation and they bloom in summer and autumn. The cutting method is: After the local temperature has stabilized at 15°C, choose 1 to 2 years of robust budding shoots (if the cutting sticks have sprouted long leaves, the new long leaves should be removed), and cut a small section of 15 to 20cm. . When the cuttings are ready for a small stick, according to the spacing of pre-inserted holes, and then insert the hibiscus branches, the depth of the soil to 10 ~ 15cm is better, that is, the depth of cut into the cuttings of 2/3, compaction of the soil, immediately after insertion Fill enough water. Note that you do not need to apply any basal fertilizer when cutting. 3. Cutting density The cutting density varies depending on the seedling transplanted or directly planted. Seedlings transplanting: In order to facilitate the operation, the width of the groove is 130cm, the height is 25cm, and the spacing is 15cm30cm. Directly inserted into the planting: You can plant 60 cm in furrows, 25 cm in height, 50 cm in plant spacing, single planting in a single row; you can also plant 90 cm in furrows, 25 cm in height, 60 cm in plant spacing, and single planting in double rows. Cultivation can use the characteristics of flowering seedlings that year, according to the seedling transplanting density cuttings, the second year after the spring each year before the budding by a certain density of thinning to ensure that the growth of mussels have enough nutrient area, to seize the high yield of flowers. 4. When the field management is transplanted and planted, the planting hole must be applied to the basal fertilizer. Generally, the waste soil or decomposed bark is applied to a small amount of compound fertilizer, and no fertilizer is generally required afterwards. However, in order to improve the yield and quality of flowers, before the flowering in summer, we should top-dress the weaker tree vigor, mix appropriate amount of compound fertilizer with waste soil, and apply it to the base in combination with weeding soil. The growth period of hibiscus should be carried out for 2 to 3 times of weeding, pay attention to the rainy season to prevent flooding, and pay attention to irrigation during the flowering weather. At the end of autumn, the late autumn shoots, the dense shoots and the weak shoots should be cut off, and the conditions should be filled with water once in the autumn to enhance the hardiness of the crucian carp. During the growing season, the pests are less harmful. They are mainly susceptible to locusts, caterpillars and ants. It is necessary to pay attention to early prevention and control and avoid using pesticides during flowering and harvesting period. 5. The harvest time of the flowers is long. In our district, we can keep opening until October in the beginning of May. There are about half of the flowering period. However, for a flower, it was opened in the early morning and withered on the second day. Therefore, flowers picked for vegetables should be picked every morning. If it is processed and dried, it should be dried after picking it in the sunny morning, and put it in a ventilated and dry place after drying. It should be protected against pressure and insects.
