There are many kinds of bamboos, there are about 500 species of 50 genera in the world. They are abundant in tropical and subtropical areas, followed by temperate zones. The center of distribution is located in the monsoon zone of Southeast Asia. my country has the largest variety of bamboos in the world and a country with a long history of operation. Now known species There are more than 150 species in 22 genera, mainly distributed in the Pearl River Basin and the Yangtze River Basin provinces (regions).
Our region has a warm climate, abundant rainfall, undulating mountains and rivers that are suitable for bamboo growth. It is one of the main bamboo-producing areas in my country. In addition to self-use, some materials are transferred to other provinces and exported every year. There are about 13 genera and 50 kinds of bamboo species known in our region. Among them, the widely cultivated and widely used ones are: Phyllostachys pubescens, green fence bamboo, brace bamboo, yellow bamboo, vermicelli bamboo, salo bamboo, car tube bamboo, horn bamboo, large head bamboo, hanging silk bamboo, large bamboo, giant bamboo, etc. . Bamboo grows fast, has a short maturity period, an early profit period, and high economic value. Planting bamboo is an important part of the diversification of the community and team, which is conducive to the consolidation and development of the collective economy. Bamboo has a well-developed root system that can condense the soil. It has fixed mud and sand, conserves water and soil, plays a role in conserving water, extending the life of the reservoir and promoting high and stable farmland yields. Bamboo has a wide range of uses.
In industrial production, because of its elasticity and toughness, bamboo can be used as scaffolding, bamboo concrete, bamboo roof beams and pillars, glued bamboo panels, etc.; it is also an important raw material for the paper and plastic industries; in agricultural production, bamboo can be used as Water pipes, farm tool handles, baskets, mud skips, bamboo awnings, bamboo mats, etc. can also be used for transportation such as bamboo bridges, bamboo rafts, etc., as buoys and wind support for offshore fishing boats; in cultural entertainment On the one hand, it can make a variety of sports equipment, exquisite arts and crafts, excellent musical instruments and exquisite toys; in daily life, bamboo can be used for various bamboo chairs, bamboo beds, bamboo strips, and various bamboo utensils and bamboo shells. It can be used for stringing and manufacturing artificial cotton, bamboo branches can be used as durable brooms, bamboo leaves can be used as hats, bamboo canopy pads, etc. Because bamboo shoots are delicious and delicious, they can be processed into dried bamboo shoots and cans, which are sold at home and abroad. Bamboo is pretty clean and beautiful, it can beautify our labor, work, study and living environment.
In short, bamboo is an indispensable resource for national socialist economic construction and people's lives. Therefore, planting bamboo has always been a favorite of the working people. In recent years, the country's economic construction has been advancing by leaps and bounds, and the production is booming. The demand for bamboo has increased dramatically. Although our district has a large area of bamboo forests, the bamboo produced still cannot meet the needs of the country's economic construction and people's lives. Therefore, we must conscientiously implement the agricultural production policy of “grain as the key link, comprehensive development”, strengthen the party’s leadership, engage in mass movement, scientific afforestation, and actively develop bamboo production, especially for the economically valuable bamboo and support. It is necessary to vigorously plant bamboo, bamboo, yellow bamboo, etc., quickly expand the area of bamboo forests, and produce abundant high-quality bamboo materials to meet the needs of national socialism construction and people's production and life.
Bamboo leaves are single leaves alternate, which can be divided into five parts: leaf blade, petiole, leaf sheath, leaf tongue and leaf ear. The leaves are green with midribs, with thousands of parallel veins on both sides. In addition to the longitudinal parallel veins, the bamboo leaves of the whip-bamboo species all have obvious transverse veins, which form a rectangular or square lattice with the longitudinal parallel veins. Bamboo leaves of clump bamboos do not have transverse veins or the transverse veins are not very obvious. Flowering of flower bamboo is relatively rare. Each floret has one piece of palea and one piece of lemma. There are 3-6 or more stamens in the palea slices, pistils in the center, 1-3 styles, 2--3 stigmas, and several scales on the ovary.
Fruit bamboos not only bloom relatively rarely, but also often do not set fruit or have a low seed-setting rate after flowering, but the seeds can be used for sowing seedlings. The fruits are mostly caryopsis, but there are also nuts, berries and pouches. Purpose Bamboo has strong toughness, long internodes and flat sections. It is suitable for splitting and weaving finer items and twisting bamboo rope. It is one of the main bamboo species used in our area and can also be used as a raw material for papermaking. The young stalks are white powdered, with high branching habits, small branches, neat and clean, graceful posture, suitable for greening bamboo species.
The characteristic is clumping bamboo. Bamboo stalks have a diameter at breast height of 3-5 cm, a height of 7-10 meters, the largest diameter of 7 cm, a height of about 15 meters, a length of 30-110 cm between nodes, white powder when young, and brown bristles in the sheath ring; high branching habit , The branches are mostly clustered, the main branch is not very obvious; the sheath leaf is rolled in, strongly inverted, the base width is 1/2-1/3 of the sheath sheath opening, the recess of the sheath sheath opening is arcuate or broad truncated, back The white powder and yellow-brown bristles are cultivated everywhere in our district, with the most counties such as Binyang, Yulin, Cangwu and Pubei. The vertical distribution can reach more than 400 meters above sea level, but it grows better in hills, flat land, foothills and river banks below 300 meters. There are many bamboo species in Guangxi. This chapter chooses the bamboo species that are commonly used in the mass cultivation and production.
