Description

Technical Field

[0001] The invention belongs to the technical field of bamboo shoot forests, and in particular relates to a method for improving the bamboo shoot growth capacity of a bamboo shoot forest. Background Art

[0002] Moso bamboo is one of the bamboo species with a wide distribution, large planting area and high economic value in my country. Moso bamboo has a short growth cycle, fast growth rate and high yield. Moso bamboo has a wide range of uses. It is not only a delicious and nutritious food for daily consumption, but also can be used as a raw material for manufacturing furniture and bamboo products. my country has long continued the way of cultivating bamboo forests for sound, but in recent years, the development of bamboo shoots dual-purpose forests has been very rapid, which has not only changed the management model of cultivating bamboo materials for sound growth by hand bamboo alone, overcome its shortcomings such as monotonous cultivation methods, extensive management, low concentration, low economic benefits, waste of resources and high costs, but also made full use of the advantages of intensive management and high commercial benefits of bamboo shoots dual-purpose forests, and promoted the healthy and sustainable development of the bamboo industry. The research and application of bamboo shoot growing technology in bamboo shoot forests is of great significance to improving the yield and quality of bamboo shoots and the economic benefits of bamboo shoot farmers. Land has an important impact on the establishment of bamboo shoot forests and the quality of products. In order to facilitate cultivation and growth, bamboo shoot forests generally choose low-lying areas or hilly areas with relatively flat terrain and thick surface layers. They can also be made to grow healthier and faster by loosening the soil and applying fertilizers. After selecting forest land and planting, bamboo shoot forests need to be fertilized in time. Because cultivating bamboo shoots on a piece of land every year will consume the nutrients of the land, in order to enable the land to sustainably cultivate bamboo shoots and bring economic benefits, the land must be fertilized. In this way, the nutrients and various minerals consumed by bamboo shoots during growth can be supplemented, and the fertility of the land will not decrease. During the cultivation process of bamboo shoot forests, a proper amount of shoots with good growth should be left so that the bamboo can grow better. Therefore, how many shoots are dug and what kind of shoots are dug have a great impact on the growth of bamboo. If the number of shoots dug is large, the bamboo will decrease, and if the number of shoots dug is small, the number of bamboo will increase. When digging bamboo shoots, we should pay attention to leaving the taller, stronger and sparse bamboo shoots, and digging out the shorter, denser and weaker ones. At the same time, we should remove the bamboos that are not growing well, so that the bamboo shoot forest can get a good harvest. According to the natural law that the bamboo shoot forest grows shoots in spring, produces whips in summer, produces shoots in autumn, and hibernates in winter, we should arrange the felling activities reasonably, apply fertilizers and turn the soil at the appropriate time, and carry out felling activities in autumn and winter. At present, China's bamboo forest management level is in the leading position in the world, but the management model is single, bamboo shoot forests are still mainly extensively managed, and the modernization level is very low. As a traditional pillar industry, the bamboo industry is highly valued, but the bamboo shoot industry is relatively lagging behind, and the industry development is unbalanced. There are problems such as low degree of industrialization, weak market competitiveness, and low market visibility. In addition, the high cost of nurturing and management has caused many bamboo farmers to sell at low prices or switch to other tree species. At the same time, in order to increase the yield of bamboo shoots, some forest farmers ignore the quality of bamboo shoots and do not follow the principle of safe cultivation. They over-apply substandard fertilizers and pesticides, which leads to an increase in toxic substances in bamboo shoots and inhibits consumption. Therefore, it is of great significance to study the bamboo shoot technology of bamboo shoot forests to improve the yield and quality of bamboo shoots and the economic benefits of bamboo shoot farmers. Summary of the invention
