Bamboo shoots

-old evergreen woody plants of Bambusoideae in Gramineae, alias shoots, ancient name bamboo buds, bamboo buds, bamboo tires. Every 100g fresh bamboo shoots contains 9.97g of dry matter,

3.28g, carbon water
compounds
4.47g, fiber 0.9g, fat 0.13g. Rich in winterin, has a tonic effect on the human body.Origin: Native China. The Herb Outline (1551-1578) is documented. There are many types, adaptable and widely distributed. There are 30 species of 550 species in the world. It is found in tropical, subtropical and tempere regions. Eastern Asia has the largest variety of 320 species, including 136 in India, 39 in Myanmar, 30 in the Philippines, 8 in New Guinea and 8 in North Korea. There are 179 species in the Americas. There are individual species in South Africa and Queensland, Australia, with few wild species found in western Asia and Europe and very few in Africa. China is one of the world's largest bamboo-producing countries, a total of 22 genus, more than 200 kinds, distributed throughout the country, to the Pearl River and Yangtze River basin, the most, north of Qinling less rain, low temperature, only a few small bamboo growth.and distribution of bamboo: the main shoots with bamboo are:(1) Phyllostachys (P.pubescens Mazel), light bamboo (P. nigra.var.henonis (Mitf.) Stapf ex. Rendle, located in the Yangtze River basin; P.praecox C.D. Chu et C.Chao), P.nuda McClure, P.dulcis McClure, P. .vivax McClure, located in Zhejiang, Jiangsu, P. congesta Rendle, in the provinces south of the Yangtze River, and P. bambusoides Sieb.et Zucc., in the Yangtze River basin and in Shandong, Henan and Shaanxi.(2) Sinocalamus (S. Latiflorus (Munro) McClure, located in Guangdong, Guangxi, Fujian, Taiwan, Guizhou, Yunnan; Located in Guangdong and Guangxi; S. beecheyanus var.pubescens P.F.Li) in Guangdong and Guangxi; Cizhu (Rendle) McClure in Guangxi, Hunan, Hubei, Guizhou, Sichuan, Yunnan; and S. Farinosus Keng et Keng f. in Guangxi, Guizhou and Sichuan.(3) Bambusa hedgehog (B.stensotachya Hack.), located in Guangdong, Guangxi, Fujian, Taiwan, B. Sinospinosa McClure, in Guangdong, Guangxi, Sichuan, Guizhou.(4) Pleiobastus Huizhu (Munro) Nakai, distributed throughout the guangdong coast.botany and reproductive conditions: root system. There are a large number of roots on the base of the bamboo pole and the bamboo whip festival. Bamboo pole by the stem, rod base, bamboo handle three parts, bamboo branches from the buds on the bamboo pole buds grow. The size, shape and color of the leaves vary according to the bamboo species, but also by the influence of environmental conditions, the rise and fall of bamboo leaves directly affect the whipping and shoot yield. Flowering is a sign of plant aging once the flowering plant dies.Bamboo shoots are the prototype of bamboo poles, even if the cut surface can be seen in the middle there are many close overlapping partitions, for the later bamboo poles within the section; The meat was wrappedthe shoots. The soft parts of the meat,and dried meat are edible.warm, bamboo can be grown in areas with an average annual temperature of 14-20 degrees Celsius, with an average temperature of 16-17 degrees Celsius (average temperature in summer below 30 degrees C, winter temperature of about 4 degrees C). Bamboo, green bamboo and hedgehog require an average annual temperature of 18-20 degrees C (of which the average temperature in January is 6-8 degrees C), and Cizhu is suitable for an average annual temperature of 16-18 degrees Celsius (of which the average temperature in January is 2-4 degrees Celsius). The plex type is better than the loose bamboo species, and the pH is 4.5-7.0 soil. Drought resistance is weak, drought inhibits nutrient growth and promotes reproductive growth;according to the distribution of bamboo shoots above ground and the growth habits of underground stems are divided into scattered, clump and hybrid types. Scatter-type bamboo species have bamboo whips, can be extended horizontally in the soil, bamboo whips have sections, long side buds on the section and give birth to whip roots. Well-developed side buds, some developed into shoots (called whip shoots), and others pumped new whips.cultivation techniques: mainly nutritional reproduction, such as mother bamboo transplantation, bambootransplantation, whipping, moving shoots, bamboo rod pressure bar, bamboo rod insertion and so on. Mother bamboo transplantation method is used the most, its advantages are high survival rate, Hsinchu rapid development, early forest, but each breeding coefficient is small, the mother plant volume large handling inconvenience. Early bamboo class should choose the base diameter of 2-3 cm of two-year bamboo for breeding. Bamboo branches should be inserted to select strong 1-2 years of raw bamboo on the side branches. General bamboo festival on the birth of 3 side branches, the center of the root is less, the root is difficult, should choose the left and right sides of the side branch insertion. The suitable planting period for bamboo in the Yangtze River basin is from November to February of the following year, which is good for the years before; It is appropriate for the side branching material to have gas roots just born in the base of the side branch between July. Bamboo mother plant transplanted 20-35 plants per acre, bambooor bamboo whip 40-55 plants per acre; 50-75 plants, whip per acre 60-90 plants; After planting, the soil is pressed and watered. Fertilizer is based on a ratio of nitrogen, phosphorus and potassium of 5:1:2. Weed loose soil, bury or cover the whip in time. Scatter-type Hsinchu shoots, every 3m or so to choose a long and strong bamboo. Shoots with bamboo forest per acre of mother bamboo 60-70 plants, more than 7 years of old bamboo is generally cut down in winter, retain the same amount of Hsinchu instead, in order to maintain a reasonable density. Clump type generally in September to choose to retain the mother bamboo, the selection of retention position should be suitable for digging shoots. More than 3 years old bamboo felled in winter. Clean up the old bamboo head every 3-4 years, cultivate soil, so that the bamboo bushes are constantly updated.bamboo shoot harvesting: bamboo whipping after 3-6 years for the bloom of shoots. Winter can dig winter shoots, before and after Qingming began to harvest spring shoots, in August to harvest whipping shoots. Early bamboo spring shoots are better than bamboo, and the yield of whipping shoots is higher than bamboo. After planting, plex bamboo began to collect shoots 2-3 years later, with the highest yield in 5-6 years, with a harvest period from April to November each year. July to August is the peak period. Bamboo shoot head just exposed the soil surface for the harvesting period, too late harvesting, fiber with a bitter taste, when harvesting to pick up the shoots around the soil, exposing the bamboo whip, according to which the shoot knife cut off the base of the shoots, digging the pit with soil to fill.Bamboo shoot production has the phenomenon of large and small years, in the management should grasp the new year appropriate reduction of the number of new bamboo, improve nutritional conditions, increase the number of whipping and pregnant shoots in that year, so that the next year the amount of shoots increased; After a few years to reach the annual retention of Hsinchu number is basically the same, gradually eliminate the size of the annual gap. Bamboo shoot production also has the phenomenon of bamboo, bamboo shoots stop growing in the middle and gradually dry or decay, the cause is malnutrition, bamboo whip farther away from the mother plant nutritional supply is insufficient, bamboo whip or bamboo head knife injury affected nutrient delivery, shoot shoots affected by adverse conditions and bamboo shoots by insect decay. Bamboo pests are more serious than diseases: the main pests are bamboo shoots, bamboo cone elephant worm, Jiangsu spring fly and so on. Use insecticides such as enemy insects to control and remove the affected bamboo shoots in time to kill the larvae.
