Continuous management method for bamboo shoot and bamboo dual-purpose forest of moso bamboo

Abstract

The invention relates to a continuous management method of a moso bamboo shoot and bamboo dual-purpose forest, which comprises the following steps: (1) selecting a management area, dividing 5-6 cutting zones along the contour line direction or within the angle range of 30 degrees with the contour line, and numbering the cutting zones as 1, 2 and 3 in sequence; (2) cutting a clear cutting belt with the serial number of 1 in the first year, cutting a clear cutting belt with the serial number of 2 in the second year, and the like, and after the clear cutting belts to be numbered are cut in sequence, starting a new round of clear cutting again; (3) after all the bamboos are cut in a cutting zone in the current year, deep ploughing and soil preparation are carried out immediately, the soil preparation depth is larger than 50 cm, large bamboo roots are removed, and 2-5 tons of organic fertilizer is added. According to the management method, strip-shaped clean cutting management and deep ploughing and organic fertilizer recarburization are carried out, particularly, waste organic materials from bamboo and bamboo shoot processing are added, meanwhile, once enough standing bamboos are reserved in the strip, the strip is converted into a bamboo shoot producing strip, only the bamboo shoots are dug, the bamboo shoots are not dug in different years, and the bamboos are not reserved any more.

Description

technical field [0001] The invention relates to a technique for sustainable management of moso bamboo forests, in particular to a method for sustainable management of moso bamboo shoots and bamboo dual-purpose forests. Background technique [0002] Moso bamboo (Phyllostachys edulis) is an important forest resource in southern China. According to the results of the eighth forest resource inventory (2013), the area of ​​moso bamboo forest in my country reached 4.43 million hm 2 , accounting for 74% of the total area of ​​bamboo forests in the country. Due to its special characteristics of renewable growth and short-term (4-6 years) harvesting, moso bamboo forest has a great potential for carbon sequestration and sinking, which has a great impact on the balance of atmospheric CO 2 has an important role. However, the traditional bamboo forest management technology mainly adopts methods such as selective cutting and annual management of bamboo shoots, which makes it difficult ...

AI Technical Summary

Problems solved by technology

However, the traditional bamboo forest management technology mainly adopts methods such as selective cutting and annual management of bamboo shoots, which makes it difficult to implement mechanized operations in the specific management of moso bamboo forests. With the increase of labor costs, this traditional management method is difficult to continue. As a result, a large number of moso bamboo forest lands were abandoned

In addition, because the whip root system of Moso bamboo forest is very strong, the distribution is mainly concentrated in the soil layer of 0-30 cm. In this way, it is difficult to reach the soil below 30 cm in daily plowing depth. Carbon sequestration and other effects are poor, and the overall function of the moso bamboo forest ecosystem is low
