The bamboo joints are deformed and beautiful, and the bamboo is resistant to insects and decay, making it the best raw material for making furniture, walking sticks, daily necessities, high-end handicrafts and decorations. The bamboo joints are deformed and bulge into abacus beads, the branches and leaves are slender and free, and the plants are upright and strong, making it the best bamboo species for making bonsai and landscaping.

[0003] At present, the cultivation and management methods of Qiongzhu are relatively extensive, and the management and maintenance are random or basically ignored; it has at least the following shortcomings.

[0004] 1) Picking bamboo shoots and keeping them for bamboo cultivation are random; some bamboo farmers only pick large-diameter bamboo shoots, some bamboo farmers pick all the bamboo shoots, and some bamboo farmers basically do not pick bamboo shoots, resulting in unreasonable distribution of keeping bamboo shoots for bamboo cultivation.

[0005] 2) The regulation of bamboo structure is unreasonable; the bamboo age structure is random, with many bamboos being 5 years old or older; the bamboos are too dense in some places and too sparse in others.

[0006] 3) Fertilization is random, or little or no fertilizer is applied, and the fertilization method is unreasonable; because only bamboo shoots are harvested for a long time, no or very little fertilizer is applied, resulting in a general lack of fertilizer in the soil, small bamboo shoots, and few bamboo shoots.

[0007] 4) The soil loosening and weeding are not done properly; the soil is compacted and overgrown with weeds, which affects the growth of bamboo shoots and bamboo; this results in: small bamboo shoots, low yield, short bamboo poles, low economic benefits, and affects the income of bamboo farmers.

[0008] Therefore, it is imperative to carry out high-yield cultivation and management of bamboo shoots and bamboo materials dual-purpose forests to increase production and increase economic output.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1 , which are photos of the specific planting process.

[0027] The high-yield cultivation method of the dual-purpose bamboo shoot forest of Phyllostachys chinensis includes: land preparation, fertilization, reasonable digging of bamboo shoots and retaining them to cultivate bamboo, felling to adjust the bamboo forest structure, and retaining branches and tips.

[0028] Land preparation includes: reclamation, soil loosening and weeding.

[0029] Reclamation is carried out every two years, with a depth of 20 to 40 cm; preferably, 30 cm is appropriate.

[0030] When reclaiming land, it is necessary to dig out the roots of shrubs, old bamboo shoots, and remove the stones in the soil. At the same time, pay attention to prevent damage to the bamboo shoots and bamboo shoots.

[0031] Reclamation is carried out in May; at this time, the new bamboo has basically sprouted branches and leaves, and forest operations will not damage or affect the growth of the new bamboo.

[0032] Soil loosening and weeding are carried out once in May-June and August-September each year to keep the forest free of weeds and shrubs; preferably, soil loosening and weeding are carried out in May and August each year; the soil loosening depth is preferably 10-20 cm.

[0033] Corresponding: Loosening the soil and weeding in May will help the soil absorb water better; it will also prevent weeds from competing with bamboo for fertilizer, which is beneficial to the growth of new and old bamboos. Loosen the soil and weed in August to remove weeds before they set seeds, thus reducing the growth of weeds. Fertilizers include: bamboo shoot-promoting fertilizer, bamboo growth fertilizer, and long-whip bamboo shoot fertilizer; Qiongzhu grows fast, produces a large amount of bamboo shoots, and has a large demand for nutrients. Reasonable fertilization plays an important role in increasing the yield of Qiongzhu shoots.

[0034] Fertilizing to promote bamboo shoots should be carried out in March, with 30 to 50 kg of nitrogen, phosphorus and potassium compound fertilizer applied per mu (preferably, 40 kg of nitrogen, phosphorus and potassium compound fertilizer is applied per mu in mid-March). This can promote the growth of more bamboo shoots, with larger bamboo shoots, higher yield and better economic benefits.

[0035] Fertilization for growing bamboo shoots is carried out in June, with 30-50 kg of nitrogen, phosphorus and potassium compound fertilizer applied per mu (preferably, 40 kg of nitrogen, phosphorus and potassium compound fertilizer is applied per mu in late May and early June to promote the growth of bamboo stalks and underground bamboo whips.) Correspondingly, the fertilization methods include furrow fertilization, hole fertilization, and broadcast fertilization, which can be selected according to the actual environment.

[0036] Specific: Furrow fertilization can be adopted in unforested land: dig a semi-circular ditch 30 cm deep and wide around the upper half of the plant, apply fertilizer, water and cover with soil. The thickness of the soil should be level with the ground. The main methods of fertilization in scattered forests are hole fertilization and broadcast fertilization. Hole fertilization is to dig holes in the scattered forests with a hole distance of 1.5m×1.5m, and a hole with a depth and width of 30cm. After applying 2 liang of compound fertilizer in each hole, water it and cover it with soil. The thickness of the soil should be level with the ground. Fertilizers can also be spread on mature forest land to save labor costs; preferably, compound fertilizers are evenly spread before it rains, and the fertilizers melt into the soil after the rain.

[0037] The long whip bamboo shoots should be fertilized in September and October, with 400-600 kg of decomposed organic fertilizer applied per mu, preferably in the ditch (preferably, 40 kg of nitrogen, phosphorus and potassium compound fertilizer should be applied per mu in late September and early October); it is beneficial to the differentiation and growth of bamboo whip shoots, so that the bamboo whip shoots are well differentiated and the shoots are large and numerous, with high yield and good economic benefits.

[0038] Specific: Dig a fertilizer trench 25 to 35 cm deep, wide, and 50 to 70 cm long; Preferably, 50 fertilizer trenches with a depth and width of 30 cm and a length of 60 cm are dug per mu, 10 kg of organic fertilizer is applied to each trench, and soil is covered after the fertilizer is applied. The thickness of the soil cover should be level with the ground.

[0039] Among them, those who are short of labor can also apply 40 kg of phosphorus-potassium compound fertilizer per mu before the rain.

[0040] In addition, it should be noted that: During reclamation, fertilization can also be carried out at the same time to save labor costs; at this time, nitrogen, phosphorus and potassium compound fertilizers are applied at a rate of 30 to 50 kilograms per mu; preferably, the rate of fertilizer application is 40 kilograms per mu.

[0041] Reasonable bamboo shoot digging, retaining and growing bamboo includes: controlling the amount of bamboo shoots dug and retaining the strong ones.

[0042] The time when bamboo shoots emerge can be divided into the early, peak and late stages. Generally speaking, the early stage is in early April, the peak stage is in mid-April and the late stage is in late April.

[0043] All bamboo shoots unearthed in the early and late stages should be dug up; among the bamboo shoots unearthed in the peak stage, the young shoots with strong growth, uniform density and largest diameter should be selected as mother bamboos.

[0044] Specifically, 900-1100 strong bamboo shoots are retained per acre each year and are evenly distributed in the forest; preferably, 1000 strong bamboo shoots are retained per acre each year.

[0045] It should be noted that if the original bamboo has a small average breast diameter and low density, more tender bamboo shoots can be left.

[0046] It should be noted that the bamboo shoots should be harvested and dug in time when they are 20 to 30 cm unearthed. Also, be careful not to damage the stems and buds when digging the shoots. Use a special bamboo shoot picker to cut the shoots in the soil and then pull them out for timely processing or sales.

[0047] Based on the applicant's many years of cultivation and test data, the most suitable standing bamboo age structure should be 1 year: 2 years: 3 years: 4 years = 1:1:1:1; and, all bamboos five years old and above should be harvested, and 2,000 to 2,500 standing bamboos per acre with an average breast diameter of 1.5 to 2 cm should be retained.

[0048] Felling and adjusting the bamboo forest structure includes: determining the reasonable standing bamboo density based on the size of the bamboo diameters and the luxuriance of the bamboo branches.

[0049] in: The average bamboo breast diameter is 2cm, and 2,000 mother bamboos are retained per mu; The average bamboo breast diameter is 1.5cm, and 2,500 mother bamboos are retained per mu.

[0050] Regarding the lushness of bamboo branches: Too dense or too sparse is not conducive to the growth of bamboo and bamboo rhizomes; if the bamboo branches are lush, cut more of them, if they are sparse, cut less of them; it is best to have a bamboo forest that can be ventilated and has sparse sunlight on the ground.

[0051] Felling to adjust the bamboo forest structure also includes: controlling the bamboo age distribution in the bamboo forest; Among them, the age structure of the reasonably controlled Qiongzhu forest is 1 year: 2 years: 3 years: 4 years = 1:1:1:1; all old bamboos 5 years old and above are cut down.

[0052] Felling and adjusting the bamboo forest structure also includes: controlling the felling time.

[0053] Among them, the time for felling old bamboo should be in June after the new bamboo unfolds its leaves; adhere to the principle of cutting down dense bamboos and leaving sparse ones, cutting down old bamboos and leaving tender ones, cutting down weak bamboos and leaving strong ones, cutting down small bamboos and leaving large ones, and not cutting down bamboos at the edge of the forest and hollow bamboos, and basically distribute the bamboos evenly, so that the bamboo forest can be ventilated and the ground has sparse sunlight.

[0054] The hook tip includes: hook tip time and hook tip length.

[0055] By reducing the top branches and leaves by hooking, nutrients can be saved, which is beneficial to the growth of bamboo rhizomes and bamboo shoots. In addition, most of the growing areas of bamboo will snow in winter, and hooking later can reduce the pressure of snow to break / bend the bamboo stalks and reduce snow damage.

[0056] Specifically, the tips of the stalks should be hooked off in June after the new bamboo shoots emerge; one-fifth of the tips of the stalks should be hooked off, and the cut should be smooth and not cracked.

[0057] The height of the bamboo stalks that are hooked later is about 3 meters, and the height of the bamboo stalks that are not hooked is about 4 meters; the number of branches left is determined according to the density of the bamboo forest, the luxuriance of branches and leaves, the number of branches of the plant, the height of the plant, etc.

[0058] Take the experimental bamboo forest of Group 1, Wenshan Village, Jiusicheng Town, Xingwen County, Sichuan Province (small place name: Luohanlin) as an example; this experimental site is a bamboo forest that has been planted for 6 years but has been poorly maintained.

[0059] There are 13,633 old bamboos in the one-acre experimental bamboo forest, with an age distribution of 1 year: 2 years: 3 years and above = 21:53:26; the average breast diameter is 0.9 cm.

[0060] The high-yield cultivation measures in the first year include land preparation, fertilization, reasonable digging of bamboo shoots, retaining bamboo shoots and cultivating bamboo, felling to adjust the bamboo forest structure, and leaving branches and hooks.

[0061] Apply fertilizer to promote bamboo shoots in March. Apply 40 kg of nitrogen, phosphorus and potassium compound fertilizer per mu to promote more bamboo shoots, large shoots, high yield and good economic benefits. The method of fertilization is broadcasting. Do it on a cloudy day before the rain. After the rain, the fertilizer melts into the soil.

[0062] Dig bamboo shoots in April and keep them for bamboo cultivation. The bamboo shoot harvesting period is from early April to late April. The early season is early April, the peak season is mid-April, and the late season is late April. Dig all the bamboo shoots unearthed in the early and late seasons.

[0063] According to statistics, 47 jin of bamboo shoots were harvested in the early stage (168 plants), 153 jin of bamboo shoots were harvested in the peak stage (605 plants), and 98 jin of bamboo shoots were harvested in the late stage (383 plants). A total of 298 jin of bamboo shoots were harvested, 1,156 plants. 605 plants were dug up in the peak stage, and 1,532 plants were left. In total, 2,688 shoots were harvested in the first year of management.

[0064] Compared with the previous extensive management output of 106 catties per mu, the output increased to 192 catties per mu, which means an 81% increase in yield.

[0065] In June, the old bamboos were cut down. At that time, the original bamboo forest was cut down; the age structure of the original bamboo forest was controlled to be 1 year: 2 years: 3 years: 4 years = 1:1:1:1; and the remaining old bamboos were controlled to be 6,000.

[0066] At the same time, hook the tip, leaving 4 / 5 of the total stalk length, and cut off the top tip.

[0067] At the same time, in June, the bamboo forest was reclaimed and weeded, with a reclamation depth of 30 cm; the roots of shrubs, old bamboo pockets and bamboo whips were dug out, and stones in the soil were removed.

[0068] In addition, fertilizer is applied while reclamation is in progress; the fertilizer applied is a nitrogen, phosphorus and potassium compound fertilizer, with an application amount of 40 kg; it is applied in holes, with a hole 15 cm deep and 15 cm wide dug for every 2 square meters, two taels of compound fertilizer is applied to each hole, and then watered and covered with soil; weeds are removed while reclamation is in progress.

[0069] In August of the same year, low secondary soil loosening and weeding were carried out.

[0070] Apply fertilizer for bamboo shoots at the end of September. Apply 500 kg of decomposed organic fertilizer per mu, which is conducive to the differentiation of bamboo shoots, large and abundant shoots, high yield and good economic benefits. Dig 50 fertilizer trenches 30 cm deep and wide and 60 cm long per mu, apply 10 kg of organic fertilizer to each trench, and cover with soil after applying fertilizer, with the thickness of the soil covering level with the ground.

[0071] Apply fertilizer to promote bamboo shoots in March of the second year.

[0072] Applying 40 kg of nitrogen, phosphorus and potassium compound fertilizer per mu can promote more shoots, large shoots, high yield and good economic benefits. The fertilization method is broadcasting. It should be done on a cloudy day before the rain. After the rain, the fertilizer melts into the soil.

[0073] Dig bamboo shoots in April and keep them for bamboo cultivation. The bamboo shoot harvesting period is from early April to late April. The early season is early April, the peak season is mid-April, and the late season is late April. Dig all the bamboo shoots unearthed in the early and late seasons.

[0074] According to statistics, 98 jins of bamboo shoots were harvested in the early stage (279 plants), 337 jins of bamboo shoots were harvested in the peak stage (1059 plants), and 181 jins of bamboo shoots were harvested in the late stage (708 plants). A total of 616 jins of bamboo shoots were harvested, 2046 plants. 1059 plants were dug up in the peak stage, and 1013 plants were left. In total, 3059 shoots were harvested in the first year of management.

[0075] Compared with the first harvest of 298 catties of bamboo shoots, the yield per mu increased by 318 catties, which means an increase of 107%.

[0076] Due to the first year of management, the average DBH of the bamboos increased compared to the previous year, reaching 1.4 cm, so 1,013 strong bamboo shoots were retained, and 4,000 mother bamboos were retained.

[0077] In June, the old bamboos were cut down. At that time, the original bamboo forest was cut down for replacement; the age structure of the original bamboo forest was controlled to be 1 year: 2 years: 3 years: 4 years = 1:1:1:1; and the remaining old bamboos were controlled to be 4,000.

[0078] At the same time, hook the tip, leaving 4 / 5 of the total stalk length, and cut off the top tip.

[0079] At the same time, the bamboo forest was loosened and weeded in June.

[0080] Fertilize at the same time as weeding; use nitrogen, phosphorus and potassium compound fertilizer, the amount of fertilizer is 40 kg; adopt hole fertilizer method, dig a hole with a depth and width of 15 cm for every 2 square meters, apply two taels of compound fertilizer in each hole, then water and cover with soil.
