Widely used and important raw material%26mdash;%26mdash; high quality fast-growing tree species

1. Bamboo willow is a new type of willow tree that uses high-tech composite germplasm materials to pass through high-tech composite germplasm. Because of its genetic basis, it not only has all the excellent characteristics of willow, but also has faster growth and resistance than other new willow varieties. Strong and good material, it is a very rare high-quality fast-growing timber tree. At the moment of vigorously creating artificial forests, experts believe that the area of ​​poplars now being built is very large, and there is a conflict between the idea of ​​creating mixed forests that is beneficial to the prevention and treatment of forest diseases at the macro level. In the past, the old willow tree species were long and curved, and the canopy was particularly large. It was used as a garden decoration, and the house was chilled in front of the house. Due to the extremely low planting density and lower economic benefits, almost no one went to large-scale development. As one of the excellent tree species, 26% of the trees;%26mdash; from the beginning of its development to the present, more and more people are spontaneously planted and highly loved. Now summarize many of its excellent features as follows:

A. Zhuliu has remarkable fast-growing characteristics and high economic benefits: after one month of growth, the rapid growth is accelerated; compared with ordinary fast-growing willows and common willows, bamboo willow grows faster and biomass Large, high output and high economic efficiency. Of course, the high efficiency generated refers to the bamboo willows under the premise of good scientific management. When the site conditions are suitable, and the management conditions such as water, fertilizer, and pest control are good, the growth of the 1-year-old tree is as high as 3-6 meters (the growth of the south is larger than that of the north, and the diameter is 2-3 cm or more. Artificial construction Short-term afforestation, no seedlings, 5-6 years can be short-term rotation or tidying, the average height of a single plant can reach 15 meters when harvested for 6 years, when the breast diameter is about 20 cm, the volume is about 0.3 cubic meters.

B. Bamboo willow has the characteristics of high-density planting characteristics and high yield: the high-density cultivation of bamboo willow has an important biological basis. Generally, the common willow tree is a dry tree with no growth center, the side branches are long, and the height of the side branches is less than 2 to 3 meters. The crown naturally forms a spherical shape and grows slowly. The bamboo willows are tree species with dry growth centers, such as tall poplars and metasequoia, the lateral branches have relatively short growth, and the branches are small, the growth potential of the lateral branches is relatively weak, and the trunk has a straight top growth advantage. Very strong, the narrow crown of the canopy is like Tianliu (Korean willow) and tall and narrow-crowned poplar. Therefore, when planting, the number of cultivated seedlings per acre is high, the land utilization rate is high, and the economic benefit per unit area is naturally high. The creation of artificial bamboo and willow forest also broke the concept of plant spacing. The standard planting mode of fast-growing poplar large diameter timber is 36 plants/mu, the standard planting mode of bamboo willow large diameter is 300 plants/mu, the standard planting mode of fast-growing poplar medium-diameter timber is 48 plants/mu, and the standard planting mode of bamboo willow medium-diameter timber is 400. Plant/mu; ultra-short-term rotation planting, 1300 plants per mu; if the biomass energy forest is cut down in the same year, it can grow 7000% 26mdash per acre; %26mdash; 10,000 plants.

C, Zhuliuxi water has strong resistance to salt and alkali, and has strong adaptability: the results of experiment on salt-alkaline soil and salt-alkali stress cultivation in Shandong coastal, Daqing show that the survival rate of bamboo will reach 70% and 90% respectively, and its limit PH value. 8.0-8.5 and salt content up to 14000ppm. It is more advantageous to plant bamboo willows in areas with better irrigation conditions or better rainfall, or in large areas such as rivers and lakes. The cultivation adaptability of bamboo willow is very strong, and almost all places where ordinary willows can be planted can grow very well. Bamboo will resist cold, drought, flood, salt and alkali, and the survival rate of cultivation is high. Planting different sizes of seedlings for cultivation in places where water can be watered. The survival rate of scientific methods is generally above 95%.

D, bamboo willows are widely used, can be widely used in paper pulp production, forestry biomass energy forest base construction: bamboo willow wood quality is good, bamboo willow wood resistance, bending, tensile, shear resistance, etc. than wild birch Better with poplar, it is the best material for making plywood, paper and high-quality frame, and the wood is fine and uniform, not hollow, not black, white from side to heart, natural whiteness is 50-60% before bleaching. The wood has a high pulp yield, soft fiber and high weaving power, so the quality of the wood pulp produced is high, and the raw material consumption is low, the alkali amount is low (only 4%), the processing temperature is low, the pressure is low, and the pressure is lowered. The production cost also greatly reduces the pollution load.

In order to ensure a stable supply of food, we ensure world food security. In terms of energy conversion technology, technology development for solid molding fuel, fuel ethanol, biomass feedstock power generation/heat supply for non-grain plant raw materials has been carried out at home and abroad. And has developed a technical process for the production of ethanol using lignocellulosic feedstock. Zhuliu high calorific value, high carbon to nitrogen ratio, high biomass, suitable for harvesting, rotation and unit production requirements of energy tree species. Excellent energy forest species should be 4 rounds for 4-6 years, and can be harvested 5-7 times in a row; energy density is high and quality is good. These requirements are eligible for bamboo willows. In such a short period of time, as long as the scientific management of fertilizer and water for planting is emphasized and strengthened (unlike forests in the past, only forests and forests are used), as long as the pest control work without pests and diseases is emphasized, efforts can be made to realize the construction of energy forest bases. Great goal.

In the case of China’s established national policy of pledge to protect 1.8 billion mu of arable land, there are still a large number of unsuitable agricultural land in the country, such as the barren hills and wasteland, the rivers and rivers, the rivers, the rivers, the islands, the beaches, the beaches, the wetlands, and the artificial reservoirs. , marginal land such as Haizi border, inland saline-alkali land, sand wasteland with high groundwater level, mines, oilfield reclamation land. According to experts' estimates, if 20% of the land is used to grow energy plants, the annual biomass growth per hectare can reach 300 million tons, equivalent to more than 150 million tons of standard coal. Liu Susheng, short-term cutting, high-density forest, used to produce raw materials for energy, has enormous resource advantages and potential. In the current situation of domestic and international production of ethanol and coal-to-liquids projects, the development of biomass liquid fuels in China is an unprecedented hot issue in the industry. The state has attached great importance to the development of forestry biomass energy. Gradually increase government input and guidance, deepen land reform and land transfer, and adopt fiscal, taxation, subsidy and other policy instruments to encourage the participation of various economic entities in the development and utilization of forestry biomass energy, and encourage and support the development of forestry biomass energy. . There are not many biomass available in China's original forests. It is necessary to speed up the construction of fast-growing, high-yield, high-energy and multi-effect energy forest bases; start the project of energy tree species cultivation and utilization, forest electricity (gas or heat) integration. Accelerate the development of forestry biomass energy. Only through cooperation and efforts in all aspects can we help to reproduce the resource advantages of artificial forests and make new and greater contributions to safeguarding national energy security, food security and accelerating the development of ecological countries.

As an excellent variety of fast-growing trees, Zhuliu is interested in many growers. After mastering the high-efficiency cultivation techniques of bamboo willows, it can achieve high-yield cultivation. This has great potential.
