Description

Technical Field

[0001] The invention relates to the technical field of pepper planting, and in particular to a method for reducing the cost and increasing the efficiency of pepper based on fruiting branch group rotation. Background Art

[0002] Sichuan pepper has a long history of cultivation in my country. It is a traditional Chinese medicine, spice and seasoning ingredient. It is known as "one of the eight major condiments" and a "medicine and food" plant. It is now widely used in food, medicine, pesticides, chemicals, health care, beauty and other fields, and has high economic value. At the same time, the cultivation of Sichuan pepper can also maintain water and soil, improve environmental quality, and has good ecological and social benefits. Therefore, Sichuan pepper is widely planted in many places as an economic crop.

[0003] At present, due to the large number of thorns on the branches and stems of Sichuan pepper, the cost of its management and picking is relatively high. In addition, under different regional site conditions, the yield and quality of Sichuan pepper vary due to factors such as climate conditions, soil quality, pruning methods, picking time, and picking methods. However, climate conditions and soil quality are almost unaffected by human factors, and pruning methods, picking time, and picking methods vary greatly in different regions.

[0004] In Sichuan and Chongqing, the method of picking branches from the whole tree is basically adopted. The harvest is concentrated in late May and early June, and all the fruiting branches are cut off. This method has the following problems: 1. The pepper is not yet mature when it is picked, and the quality and yield of the pepper picked at this time will be affected; if the pepper is picked after it matures, it cannot be cultivated to form fruiting branches in the next year, and the pepper will have low yield or even no yield in the next year; 2. The picking time is short, and all fruiting branches need to be quickly cut off and dried in a short period of time, which is labor-intensive; 3. A large amount of fertilizer and water is required. Once the nitrogen is excessive, it will cause the branches to grow vigorously and affect the quality of flower bud differentiation; at the same time, a large amount of plant growth regulators (such as ethylenediamine) need to be used multiple times. Improper control will cause physiological disorders in the pepper tree, which is easy to cause "yellow flowers" and cause a total loss of yield.

[0005] In areas such as the dry and hot valley of the Jinsha River in Yunnan, the spring is relatively dry and rainy. The "spring dryness and summer rain" climate causes the pepper trees to bloom later, and the picking time (generally from late July to early August, and in some areas until the end of September) is later than that in Sichuan and Chongqing. The whole tree stake picking method is not suitable for the operation and management of pepper in this area. The method that is more suitable for this area is the "four-arm flat" pruning method, which is also a "full pruning" + "drug promotion" method. From late June to early July, all fruiting branches are cut off, and drugs are used to promote branch aging. This method has the following problems: 1. Picking is carried out in late June to early July, which is the dog days of summer in the dry and hot valley area of ​​Yunnan. At this time, there is sufficient sunlight. After all the fruiting branches are cut off, the remaining main branches will be exposed to the sun, and the sun-facing side of the main branches of the pepper will crack due to exposure to the sun. The whole plant may be killed by the sun. Even if measures are taken to save it, it will be difficult for the fruiting branches to bear fruit the following year; 2. The pepper is not yet mature when picked, and the quality and yield of the pepper are affected. Similar to the Sichuan and Chongqing areas, if the pepper is harvested after it matures, it will not form fruiting branches for the following year, resulting in a total crop failure in the following year; 3. The production cost is high. The trunks picked by this method must be cultivated to form fruiting branches for the following year within the same year, and physiological regulation such as bud promotion and aging must be continuously carried out through drugs. During this period, the purchase and spraying of drugs and branch regulation require a lot of manpower and financial resources.

[0006] In addition, there is a method of changing branches and producing peppers for green pepper in related technologies. This method overcomes the unfavorable conditions such as time and season, and does not require drug regulation, and achieves the problem of stable and high yields of green pepper and reduced harvesting costs. However, in the actual production and management of pepper, if the technical measures are not used properly, it will cause branches to be disorderly, crowded and shaded, and the branches to be uneven in thickness, length, and strength. The thin and weak branches have fewer and smaller inflorescences, and the strong branches have more secondary branches. The new branches take a long time to elongate, which affects the yield.

[0007] Therefore, there is an urgent need to study a method for reducing costs and increasing efficiency of pepper with good quality, stable yield, low production cost and easy operation, so as to adapt to the planting and management of pepper under the site and climatic conditions of different regions. Summary of the invention

[0008] To this end, the present invention provides a method for reducing costs and increasing efficiency of Zanthoxylum bungeanum based on rotation of fruiting branch groups to solve the above-mentioned technical problems.

[0009] In order to achieve the above object, the present invention provides the following technical solutions:

[0010] A method for reducing costs and increasing efficiency of pepper based on fruiting branch group rotation, comprising:

[0011] Tree shape cultivation: It takes 1-3 years to build a fruiting branch group rotation pruning tree shape, which includes a trunk, primary branches and secondary branches. There are 4 primary branches, which are evenly distributed around the trunk and at different heights (the first primary branch from the ground is 50-60 cm above the ground, and the heights from the adjacent primary branches are 20-30 cm, 50-80 cm, and 20-30 cm respectively). The base angle of the primary branch (the angle between the primary branch and the central trunk) is 50°-60°. During the cultivation period, three secondary branches are selected on the primary branches for cultivation; after the tree shape is formed, there are several secondary branches distributed on each primary branch (upright, under-back, thin, diseased and insect-infested young branches are removed, and young branches with slanted branches and uniform growth are selected for cultivation. The number and spacing of branches to be retained should be determined in combination with site conditions and tree vigor), and several tertiary branches are distributed on the selected secondary branches (upright, under-back, thin, diseased and insect-infested young branches are removed, and young branches with slanted branches and uniform growth are selected for cultivation. The number and spacing of branches to be retained should be determined in combination with site conditions and tree vigor). Tree shape cultivation includes trunk pruning, selection and shaping of primary and secondary branches.

[0012] Fruiting branch group cultivation and picking: Divide the four first-level branches into the current year harvest group and the next year harvest group, and alternate between the current year harvest group and the next year harvest group. In the year of harvest, all the second-level fruiting branches on the current year harvest group and the third-level fruiting branches on the selected second-level branches are cut off, and the height of the pile is not more than 2cm on the basis of retaining 1-2 buds; the second-level branches on the two first-level branches of the next year harvest group and the third-level branches on the reserved second-level branches are pruned and cultivated as the next year's fruiting branch group, and then the cycle is alternated.

[0013] Furthermore, the trunk pruning includes: cutting off the top of the trunk to keep the length of the trunk at 50-60cm.

[0014] Furthermore, the first-level branch selection and shaping includes: selecting 4 young branches that meet the angle and height difference from multiple young branches on the main trunk and cultivating them as first-level branches; if there are no young branches that meet the requirements at the corresponding position on the main trunk, using suitable young branches to change the direction of the young branches by pulling, supporting, twisting or pressing, and using the young branches to cultivate first-level branches; if the selected first-level branches are thin and drooping, they are supported and shaped to maintain a preset angle with the main trunk, and the support is removed after the first-level branches grow thick.

[0015] Furthermore, the selection and shaping of secondary branches include: selecting 3 secondary branches from each of the 4 primary branches for cultivation, avoiding the selection of downward-facing, upright, weak or diseased and insect-infested branches, and selecting oblique, strong and vigorous young branches for cultivation.

[0016] Furthermore, after the tree shape is cultivated and formed, there are several secondary branches distributed on each primary branch. The upright, downward, thin, diseased and insect-infested young branches should be removed, and the young branches with slanted branches and even growth should be selected for cultivation. The number and spacing of the branches to be retained should be determined in combination with the site conditions and tree vigor. There are several tertiary branches distributed on the selected secondary branches. The branches to be retained and removed are consistent with the branches of the same level. The number and spacing of the branches to be retained should also be determined according to the tree and the site.

[0017] Furthermore, in the year of harvest, the new branches in the harvest group of the following year are selected by removing the weak and keeping the strong, and the upright, overgrown branches, drooping branches, weak branches, and nutrient branches are cleared away.

[0018] Furthermore, after pruning, the cut ends are disinfected and then a protective agent is applied.

[0019] Furthermore, the primary branches are inclined upward and the angle between the primary branches and the main trunk is 50-60°, the angle between the secondary branches and the primary branches is 50-60°, and the spacing between adjacent secondary branches on the same primary branch is 10-15 cm.

[0020] The present invention has the following advantages:

[0021] The present invention provides a method for reducing the cost and increasing the efficiency of pepper based on the rotation of fruiting branch groups. In the initial 1-3 years, tree formation cultivation is carried out and pepper is not picked during this period. After the tree formation is formed, each pepper tree is semi-picked in rotation every year, and during this period, the unpicked rotation branch groups are cultivated for fruiting branch groups. After the tree shape cultivation is completed, the main trunk, primary branches and secondary branches will no longer change, and the four primary branches are in four directions and distributed at four heights, so the primary branches and secondary branches are clearly layered; the secondary or tertiary fruiting branch groups thereon are limited in length, so there will be no problem of disorderly branches; when picking every year, all the fruiting branch groups are cut off by branch picking, and the fruiting branch groups of the following year are pruned at the same time, so there will be no problem of new branches or fruiting branches crowding or hiding each other; since the main trunk, primary branches and secondary branches are clearly layered and almost unchanged, only new branches or fruiting branches to be cultivated need to be pruned, which is relatively simple and easy for farmers to master; the rotating half-picking method allows at least half of the branches to be retained on the main trunk, which can effectively block the sun's exposure to the main trunk and avoid flowering. The problem of pepper trees dying from excessive exposure to the sun; rotational picking allows the fruiting branches to have two years to grow naturally, so there is no need for "drug promotion"; more importantly, for the dry and hot valley area of ​​​​the Jinsha River in Yunnan, because the fruiting branches are cultivated for two years, they can wait until the pepper is fully mature before picking the branches, without being restricted by time nodes, and there is no problem of poor growth of fruiting branches the following year due to late picking, and the pepper picked after maturity is of better quality; the same pepper tree is rotated and half-picked, which provides more nutrients to the fruiting branches that year, making the pepper fruits large in size, pure in taste, and high in oil content, which improves the quality of the pepper; branch picking is used instead of ear picking, which has high picking efficiency, and the picked branches can go directly into the drying room; the tree has balanced growth and development, achieving both growth and fruiting.

[0028] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0029] The present embodiment provides a method for reducing costs and increasing efficiency of pepper based on rotation of fruiting branch groups, comprising the following steps: step S1, tree-shaped cultivation; step S2, fruiting branch group cultivation and picking.

[0030] In step S1, a fruiting branch group rotation pruning tree shape is constructed in 1-3 years, and the fruiting branch group rotation pruning tree shape includes a trunk 1, primary branches 2 and secondary branches 3. There are 4 primary branches 2, and the 4 primary branches 2 are evenly distributed around the trunk 1 and are at different heights (the first primary branch 2 from the ground is 50-60 cm above the ground, and the heights from the adjacent primary branches 2 are 20-30 cm, 50-80 cm, and 20-30 cm respectively), and the base angle of the primary branch 2 (the angle between the primary branch 2 and the central trunk 1) is 50°-60°, generally in At about 60°, three secondary branches 3 are selected and retained on the primary branches 2 for cultivation during the tree shape cultivation period; after the tree shape cultivation is formed, a number of secondary branches 3 are distributed on each primary branch 2 (upright, under-back, thin and weak, diseased and insect-infested young branches are removed, and young branches with slanted branches and uniform growth are selected for cultivation. The number and spacing of the retained branches shall be determined in combination with the site conditions and tree vigor), and a number of tertiary branches are distributed on the retained secondary branches 3 (upright, under-back, thin and weak, diseased and insect-infested young branches are removed, and young branches with slanted branches and uniform growth are selected for cultivation. The number and spacing of the retained branches shall be determined in combination with the site conditions and tree vigor). Tree shape cultivation includes trunk pruning, primary and secondary branch selection and shaping.

[0031] The tree shape cultivation comprises the following steps: step S11, pruning the trunk 1; step S12, selecting and shaping the primary branches 2; step S13, selecting and shaping the secondary branches 3.

[0032] In step S11, the top of the trunk 1 is cut off to keep the length of the trunk 1 at 50-60 cm.

[0033] In step S12, four young branches that meet the angle and height difference are selected from the multiple young branches of the trunk 1 and cultivated as primary branches 2; if there are no suitable young branches at the corresponding positions on the trunk 1, suitable young branches are used to change the direction of the young branches by pulling, supporting, twisting or pressing, and the primary branches 2 are cultivated with the young branches; if the selected primary branches 2 are thin and drooping, they are supported to maintain a preset angle with the trunk, and the support is removed after the primary branches 2 grow thick.

[0034] In step S13, three secondary branches 3 are selected from the four primary branches 2 for cultivation. Avoid selecting the downward, upright, weak or diseased branches, and select the oblique and strong young branches for cultivation.

[0035] In step S2, the four primary branches are divided into the current year harvest group 100 and the next year harvest group 200, and the current year harvest group and the next year harvest group are alternately rotated. In the year of harvest, the secondary fruiting branches on the current year harvest group and the tertiary fruiting branches on the selected secondary branches are all cut off, and the height of the pile is not more than 2 cm on the basis of retaining 1-2 buds; the secondary branches on the two primary branches of the next year harvest group and the tertiary branches on the reserved secondary branches are pruned and cultivated as the next year's fruiting branch group, and then the cycle is alternated.

[0036] After the tree shape is formed, the four first-level branches 2 are divided into the current year harvest group 100 and the next year harvest group 200, with two first-level branches 2 that are opposite to each other in the circumferential direction as a group. Figure 1 As shown, Figure 1 The position of the harvest group 100 of the current year and the harvest group 200 of the next year are shown in FIG. Figure 2 As shown, Figure 2 The positions of the current year harvesting group 100 and the next year harvesting group 200 after rotation are shown in FIG. Figure 1 and Figure 2 This is only for illustrating the rotation method of the current year's harvesting group 100 and the next year's harvesting group 200, and does not limit which two opposing primary branches 2 are specifically adopted by the current year's harvesting group 100 and the next year's harvesting group 200.

[0037] After the tree shape is cultivated, there are several secondary branches 3 distributed on each primary branch 2. It is necessary to remove upright, downward-facing, thin and weak, diseased and insect-infested young branches, and select young branches with slanted branches and uniform growth for cultivation. The number and spacing of the remaining branches shall be determined in combination with the site conditions and tree vigor; there are several tertiary branches distributed on the selected secondary branches 3. It is necessary to remove upright, downward-facing, thin and weak, diseased and insect-infested young branches, and select young branches with slanted branches and uniform growth for cultivation. The number and spacing of the remaining branches shall be determined in combination with the site conditions and tree vigor.

[0038] In the year of harvest, the new branches on the harvest group 200 of the following year are selected by removing the weak and keeping the strong, and the upright, overgrown branches, drooping branches, weak branches, and nutrient branches are cleared away.

[0039] After pruning, disinfect the cut ends and apply a protective agent to prevent infection.

[0040] The embodiment provides a method for reducing costs and increasing efficiency of pepper based on rotation of fruiting branch groups. In the first 1-3 years, tree formation cultivation is carried out and pepper is not harvested during this period. After the tree formation is formed, each pepper tree is semi-harvested in rotation every year, and during this period, the unharvested rotation branch groups are cultivated for fruiting branch groups. After the tree shape cultivation is completed, the main trunk 1, primary branches 2, and secondary branches 3 no longer change, and the four primary branches 2 are in four directions and distributed at four heights, so the primary branches 2 and secondary branches 3 are clearly layered; the secondary or tertiary fruiting branch groups thereon are limited in length, so there will be no problem of disorderly branches; when picking every year, all the fruiting branch groups are cut off by branch picking, and at the same time, the fruiting branch groups of the following year are pruned, so there will be no problem of new branches or fruiting branches crowding or hiding each other; since the main trunk 1, primary branches 2, and secondary branches 3 are clearly layered and almost unchanged, only new branches or fruiting branches to be cultivated need to be pruned, which is relatively simple and easy for farmers to master; the rotating half-picking method allows at least half of the branches to be retained on the main trunk 1, which can effectively block the sun's exposure to the main trunk. , which can avoid the problem of pepper trees dying from overexposure; rotational picking allows the fruiting branches to have two years to grow naturally, so there is no need for "drug promotion"; more importantly, for the dry and hot valley area of ​​​​the Jinsha River in Yunnan, because the fruiting branches are cultivated for two years, they can wait until the pepper is fully mature before picking the branches, which is not restricted by time nodes. There is no problem of poor growth of fruiting branches the following year due to late picking, and the pepper picked after maturity has better quality; the same pepper tree is rotated and half-picked, which provides more nutrients to the fruiting branches that bear fruit that year, making the pepper fruits large in size, pure in taste, and high in oil content, which improves the quality of the pepper; branch picking is used instead of ear picking, which has high picking efficiency, and the picked branches can go directly into the drying room; the tree has balanced growth and development, achieving both growth and fruiting.
