Detailed Description
The invention provides a pruning and shaping method for young trees of south China fir for timber, which comprises the following steps: when the height of the young forest of the south China fir is 50-60 cm, each plant selects the highest and vigorously growing branch as a main trunk for cultivation, all other tillers are removed, and a weed control cloth is used for covering tillering cut openings and peripheral weeds by taking the main trunk as a center; when the growing height of the trunk reaches 1.5-2.5 m, trimming off all lateral branches below the height of the trunk 1/3.
When the height of the young forest of the south China fir is 50-60 cm, the highest and vigorously growing branch is selected as a main trunk for cultivation of each plant, all other tillers are removed, and a grass prevention cloth is used for covering tillering cut openings and peripheral weeds by taking the main trunk as a center. The young forest of the south China fir has the characteristics of serious tillering, unobvious trunk and excessive lateral branches at the bottom of the trunk, so that the highest or most vigorously growing branch is reserved, the branch is cultivated into the trunk, and other tillering parts are completely cut off. When the tillers are cut off, the preferred cutting distance is 1-2 cm from the root.
After the trimming, the grass-proof cloth is paved by taking the trunk as the center, and the grass-proof cloth is environment-friendly woven cloth. The grass-prevention cloth is made of biodegradable materials, is round with the radius of 50-100 cm, has the functions of grass prevention, water seepage and ventilation, has the service life of 3-5 years in a field environment and the decomposition life of less than 10 years, can be absorbed by soil after decomposition, and cannot pollute the soil and the environment. The grass prevention cloth also needs to cover all cut openings for pruning and tillering, avoids the regeneration of plants, promotes the growth of the reserved main stems, reduces weeds around the main stems, can reduce the evaporation of water in the sun, promotes the quick growth of the main stems, and reduces the manual tending cost.
When the growing height of the trunk reaches 1.5-2.5 m, all lateral branches below the height of the trunk 1/3 are trimmed. According to the method, after tillering is cut off, a large number of lateral branches are still bred at the bottom of the trunk of the young tree of the south China fir, so that the high growth of the tree is influenced, and therefore all the lateral branches below 1/3 of the trunk are trimmed. According to the invention, when the lateral branches are trimmed, the trimmed lateral branches are not completely cut off to promote nutrient backflow, and the trimming opening is preferably 5-8 cm away from the trunk, so that the trunk is prevented from being damaged. The pruning is carried out once in the growth and development period of the young forest of the sequoia fortunei in south China. The pruning method is beneficial to promoting the growth, height and length of the seedlings of the south China fir, is beneficial to shortening the time for the young forest of the south China fir to grow into the forest, and has great significance for the smooth growth of the young forest of the south China fir.
