Description

Technical Field

[0001] The invention relates to a method for transplanting mother bamboo of the genus Fargesia, and belongs to the technical field of forestry seedling cultivation. Background Art

[0002] In forestry production, Fargesia bamboo species have difficulty taking root and have extremely low survival rates after transplantation, severely limiting their transplantation and industrialized afforestation. These species have thick culms that are difficult to cut, and they have few fibrous roots, making their roots particularly susceptible to damage during digging and transplanting, making root regeneration difficult. Furthermore, due to their long rooting time, traditional transplanting methods, such as splitting and dividing, have extremely low survival rates. Traditional transplanting methods often fail to effectively protect the root system, resulting in a high rate of transplant failure. To date, there are no established cases of transplanting and cutting production of Fargesia bamboo species. Summary of the Invention

[0003] In order to solve the problems existing in the transplanting of mother bamboos of the genus Fargesia in the mountains, the present invention provides a method for transplanting mother bamboos of the genus Fargesia by splitting the stumps, which specifically comprises the following steps:

[0004] (1) Cupping: After the bamboo shoots grow to 30-50 cm, dig up the soil layer at the base of the bamboo shoots to expose the base of the bamboo shoots and the stalk, and put the seedling cup from the top of the bamboo shoots down to the base of the bamboo shoots.

[0005] (2) Filling soil and applying fertilizer: Place a layer of vermiculite at the bottom of the seedling cup, spread decomposed organic fertilizer on the vermiculite layer, cover the decomposed organic fertilizer with fertile field soil or humus soil, and water it sufficiently.

[0006] (3) Watering with rooting powder: After the bamboo shoots have grown into stalks, start watering with rooting powder during the spring drought season of the following year (for example, if the bamboo shoots have grown into stalks this year, start watering with rooting powder during the spring drought season of next year).

[0007] (4) Cutting the stalk: In the dry season after the rainy season ends in the following year after the bamboo shoots have grown into stalks, dig up the soil around the seedling cup to expose the stalk below the seedling cup of the mother bamboo. Use a sharp machete to cut off the stalk from the thinnest part below the seedling cup, and do not tear the stalk.

[0008] (5) Binding and pruning: Use the rope above the cup body to bind the mother bamboo from the base, cut off the top of the mother bamboo, leaving only 1 to 2 rounds of branches, cut off all the tender branches and leaves, and keep the mother bamboo moist.

[0009] (6) Transplantation: When transplanting, bury the seedling cup together with the mother bamboo in the soil. After covering with soil, water it thoroughly and then cover it with a layer of black plastic film to provide shade to increase soil temperature and promote root regeneration.

[0010] Preferably, the seedling cup in step (1) includes a cup body 1, an opening 2, a non-woven fabric 3, and a rope 4; a circular opening 2 is provided in the center of the bottom of the cup body 1, a circle of non-woven fabric 3 is provided on the upper edge of the cup body 1, and a rope 4 is provided at the upper edge of the non-woven fabric 3. By pulling the rope 4, the non-woven fabric 3 can be contracted to prevent the soil from scattering.

[0011] Preferably, the cup body 1 is cylindrical with an upper bottom diameter of 25 to 35 cm, a lower bottom diameter of 20 to 30 cm, and a height of 40 to 50 cm.

[0012] Preferably, the cup body 1 is made of black polypropylene non-woven fabric.

[0013] Preferably, the diameter of the circular opening 2 is 5 to 6 cm; the width of the non-woven fabric 3 is 10 to 15 cm.

[0014] Preferably, in step (2), the thickness of the vermiculite layer is 5 to 10 cm; the thickness of the decomposed organic fertilizer is 10 to 15 cm; and the thickness of the fertile field soil or humus soil is 15 to 20 cm.

[0015] Preferably, the rooting powder is irrigated in step (3) as follows: an NBT rooting powder solution with a concentration of 500-800 ppm is applied every 15 to 30 days, and the application amount for each seedling cup is 100-200 mL; 30 days before transplanting, a mixed solution containing 500-800 ppm NBT rooting powder solution and 50-150 ppm methyl jasmonate solution is irrigated into each seedling cup, the volume ratio of the NBT rooting powder solution to the methyl jasmonate solution in the mixed solution is 1:1, and the application amount of the mixed solution to each seedling cup is maintained at 100-200 mL.

[0016] Preferably, the rooting powder in step (3) is not applied in winter or on rainy days.

[0017] Technical effects of the present invention:

[0018] (1) The method of the present invention can control the growth of bamboo roots in the seedling cup without digging up the hard-to-root alpine Fargesia bamboo shoots, thereby avoiding damage to the root system of the hard-to-root alpine Fargesia bamboo shoots caused by repeated digging and planting.

[0019] (2) The present invention controls the root system of the difficult-to-root alpine Fargesia mother bamboo to grow in the seedling cup, effectively protecting the bamboo root system and avoiding the problem that the root system is difficult to dig and easily damaged during the bamboo transplanting process.

[0020] (3) The present invention effectively solves the problem that the root system of the bamboo species of the genus Fargesia is underdeveloped, the number of roots is small, it is difficult to fix the soil, the soil is easily shed to form bare-root seedlings, and the survival rate of transplantation is extremely low.
