6000 yuan / kg of rare vegetables Gexian rice planting technology
Gexianmi is not a rice, but a freshwater wild algae plant. Hebei Hefeng has a high yield and good quality. Therefore, Gexianmi has become a famous local specialty and has obtained the national agricultural product geographical indication certification. The following small series will introduce Ge Xianmi. In 2011, Ma Gexianmi passed the agricultural product geographical indication certification of the Ministry of Agriculture. Ge Xianmi has become a unique advantage industry for the agricultural and rural economic development of Peima Town, Hefeng County, and has become an important way for poor farmers in the main producing areas to accurately alleviate poverty and accurately eliminate poverty. The products are sold at home and abroad and are well received by the market. The current price is as high as 5,000~6 000 yuan/kg. The technical specifications for the cultivation of Gexianmi are now shared as follows. 1 Geographical scope Walking Horse Town is located in the southwest of Hefeng County, Hubei Province. It has a total area of ​​1 050 hm2 in the Magexianmi Protection Area. It is adjacent to the Hupingshan Tourist Area in Hunan Province in the east and Zhangjiajie Scenic Area in the south. It is 600 km away from Wuhan and Changsha and 270 km away from Yichang. Geographical coordinates are 109°8′~110°03′ east longitude and 29°39′~30°09′ north latitude. The average elevation is 920 m. The jurisdiction includes Qianjin, Wangjiabao, Gucheng, Yanghe, Liqiao, Baiguo, Jinlong, Guancang, Liujiatun, Huaqiao, Shengzi, Locking, Gangjiawan, Jiuling and Beizhen. There are 20 villages in Jingang, Dadian, Meiping, Hongtu and Jiudong. 2 natural ecological environment The special soil for the survival of Gexianmi is phosphorus-rich soil, and Peima Town is one of the four major phosphate mines in the country. The land area weathered by phosphate rock is 4 924 hm2, of which the cultivated area is 1 935 h. M2. The terrain is high in the northwest, low in the southeast, with large gaps, mountains and mountains, peaks and undulations, and rivers and rivers. It has the characteristics of hills and mountains. The town is subtropical and non-monsoon humid climate, with four distinct seasons, cold winter and hot summer, cool spring and autumn, rain and heat in the same season, obvious three-dimensional climate, annual average temperature of 12.2 °C, annual accumulated temperature of 3 691 °C, frost-free period of 225 d, annual average rainfall It is 1 900 mm. There is no “three wastes†emissions and air pollution. The surface water meets the national Class II water quality standards and is naturally pollution-free. The produced Gexianmi is a pure natural food. 3 Human history Ge Xianmi is not a cereal. It is called "rice" because it is shaped like rice. It is round and dry after being dried. It is larger than rice when cooked. Attached to rice fields, shallow pools, lakes, streams of sand and gravel or wet soil, spherical gelatinous shape, like a fungus, so called "water fungus" or "field fungus." There are no roots, stems and leaves floating in the water, so it is also known as "Tian Xian Mi" or "Tian Xian Cai". It is made up of many cells and becomes a rosary-like group. The color is blue-green, the particles are round and sleek, and it is comparable to pearls. If cooked into a dish, the taste is very fresh, and it is a treasure on the banquet, so it is called "Lemonweed". "Compendium of Materia Medica" records: "Ge Xianmi, Shenghuguang along the stream (now the jurisdiction of the town of Hema Town, Hefeng County, Hubei Province) in the paddy field, in the face of heavy rain scouring the mouth, this rice flows out, the natives take it, when it is first taken Such as small fresh fungus, purple green, mixed with vinegar, fat green edible." Eastern Jin Dynasty, alchemy home, medical scientist, Taoist ethicist Ge Hong route Hefeng to suffer from diseases, the harvest year to eat, even health The effect of the body, later Ge Hong into the DPRK to devote the emperor, the frail and ill-fated Crown Prince eats, the disease is strong, the emperor feels Ge Hong's merits, and the name "Ge Xianmi" has been used until now. The history of the Qing Dynasty is recorded as a tribute and a royal meal. The last dish of the emperor Pu Yi’s book "My First Half Life" is called "Ducking Dang Gexianmi". 4 Unique production technology 4.1 Origin leveling In the protected area, choose rice fields with air, soil and irrigation water quality that meet the national or industry standards. It is required to have flat terrain and convenient irrigation and drainage. In autumn and winter, the soil will be ploughed, broken, rice straw removed, leveled and watered. Keep the water depth 5~15 cm throughout the culture period. 4.2 Algae cultivation In the paddy rice field of the reserve, the elite group of Geomaxianmi is selected and cultivated in large quantities indoors. The population of Gexianmi must be 1 mm in diameter to be used as algae species. When planting, spread it evenly in the paddy field at a density of 30~60 g/m2, so that the Gexianmi group is exposed on the surface of the soil, which is good for receiving photosynthesis by sunlight. Do not stir the water body to avoid the group being buried in the soil. 4.3 Sowing season The growth period of Gexianmi is from November to May, mainly concentrated in the temperature rise from late February to mid-April. It can be planted every year from November to February, and can be flexibly controlled according to the actual use of paddy fields. The low temperature is beneficial to the adaptation of Gexianmi to the external environmental conditions and enhance the stress resistance of the Gexianmi population. 4.4 Field Management Ge Xianmi is extremely sensitive to soil environmental pH and chemical substances. Fertilizer has a great influence on the growth of Gexianmi. Excessive use of ammonium nitrogen fertilizer, urea and herbicides will cause severe reduction of Gexianmi. Therefore, the fertilization should be carried out by increasing the application of organic fertilizer in the winter, mainly using the fertile soil, fertilizer, and fertilizer, and fertilizing combined with the cultivating and loosening soil. In winter, the temperature is low, and the Gexianmi group is prone to water loss due to low temperature icing, affecting the growth of the population until the death of the group. During the whole culture period, it is necessary to ensure that the Gexianmi group is completely submerged under water. 4.5 Harvesting at the right time After entering April, as the temperature rises, Gexianmi grows faster and faster. It can usually be harvested from mid-April to mid-May, or it can be harvested in advance according to the needs of rice fields. 300-800 g of fresh rice algae can be harvested per 1 m2 paddy field. When the group of Gexianmi is dark green and beaded, it is harvested in a clear weather. It is harvested with bamboo utensils and must be kept in a deep water layer of about 17 cm. 4.6 Post-harvest processing After harvesting, the plant is transported to the factory for initial processing. The staff needs technical training and certification. The processing includes manual removal of impurities, rinsing, draining, drying, air selection, and manual re-selection. And then graded packaging for listing. According to the size, the horses can be divided into three grades: special grade, first grade and second grade. Ge Xianmi is usually packed in carton and marked with the product's net quality, grade and trademark. 5 sensory characteristics The finished product is dark green granules, no odor, no non-Gexian rice inclusions; dark green after restoration, the diameter is no more than 8 mm, round bead shape, exquisite and clear, with a unique fragrance of the gems, the soup is colorless Clear and bright. 6 Intrinsic quality indicators Take 100 grams of dried rice with protein ≥ 24 g, ash ≤ 10 g, moisture ≤ 18 g. The above is the planting technology of Gexianmi, I hope to help you. If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
