Description

Technical Field

[0001] The present invention relates to the technical field of fruit tree planting, and particularly discloses a method for obtaining parameters based on apricot and plum planting and an apricot and plum planting method. Background Art

[0002] Apricots and plums are high-yielding and boast excellent fruit quality. They are highly adaptable to soil conditions and resistant to drought and cold weather, allowing them to be cultivated in most areas of their suitable habitats. As the cultivated area expands, farmers are shifting their focus from expanding production to improving fruit quality and increasing profitability, ultimately leading to efficient production. However, in production, the problem of balancing yield and fruit quality often arises when the planting load is inappropriate. This means that high yields can lead to poor fruit quality, while good quality results in low yields. Therefore, determining the appropriate planting load is crucial.

[0003] During the production of apricots and plums, branches often break due to excessive load, which affects yield and has a direct impact on economic benefits. In addition, unreasonable fruit thinning spacing will not only affect yield, but also reduce economic benefits and affect the quality of apricots and plums.

[0004] Apricot plums, with their high yield and excellent fruit quality, are a new variety with great market prospects and promotional value. Despite their high yield and nutritional value, excessively high planting rates have been found to cause branch breakage, reduced fruit quality, and flavor degradation. Therefore, determining the appropriate planting rate is crucial and has a direct impact on improving economic returns.

[0005] However, there is no scientific method in the prior art to obtain the specific parameters that should be used in the apricot and plum planting process. Summary of the Invention

[0006] In view of the problems of the prior art, the present invention provides a method for obtaining apricot and plum planting parameters, and the technical solution adopted is:

[0021] The following treatments were performed on each apricot and plum branch and each apricot and plum branch group:

[0022] The branches or branch groups were pulled at the base, middle and top respectively until they broke. Each test was repeated three times to obtain the theoretical load capacity of branches and branch groups with different base diameters at different opening angles.

[0045] Step 4: After the fruit dropped naturally, each experimental group was thinned at the following distances: 6 cm, 10 cm, 14 cm, and 18 cm, with one experimental group corresponding to one thinning distance.

[0046] Step 5: Test the quality of each fruit picked after maturity, so as to obtain the experimental parameters corresponding to the experimental group with the best fruit quality as the planting parameters.

[0055] The base diameter of the third branch group ranges from 1.8CM to 2.2CM.

[0056] In this embodiment, the 30 kg tensile force gauge is used to perform branch pulling treatment on apricot and plum branches with base diameters in the first branch base diameter range, the second branch base diameter range, and the third branch base diameter range at opening angles of 30°, 45°, and 60°, and on apricot and plum branch groups with base diameters in the first branch group base diameter range, the second branch group base diameter range, and the third branch group base diameter range, respectively, thereby obtaining theoretical load capacities of branches with different base diameters at different opening angles and theoretical load capacities of branch groups, including:

[0058] The branches or branch groups were pulled at the base, middle and top respectively until they broke. Each test was repeated three times to obtain the theoretical load capacity of branches and branch groups with different base diameters at different opening angles.

[0059] In this embodiment, the maximum and minimum number of fruits that a single apricot and plum branch can bear at different opening angles and the same base diameter are calculated based on the theoretical load capacity of branches with different base diameters and the average weight of a single fruit at different opening angles. The following method is used:

[0061] In this embodiment, the maximum and minimum number of fruits that a branch group with different opening angles can bear are calculated based on the theoretical load capacity of branch groups with different base diameters at different opening angles and the average weight of a single fruit. The following method is used:

[0062] The maximum (minimum) number of fruits in a branch group = maximum (minimum) theoretical load / average single fruit weight.

[0063] The present application also provides a method for planting apricot and plum trees, the method comprising:

[0077] The present application is further described in detail below by way of examples. It should be understood that the examples do not constitute any limitation to the present application.

[0078] Example 1

[0079] This embodiment provides a technology for improving fruit quality and yield by regulating the angle of apricot and plum branches and the amount of fruit produced, including the following steps:

[0080] (1) Branch selection: The medium-long branches with a length of more than 25 cm were selected for the experiment. A 30 kg tensile force gauge was used to pull the branches of the apricot plum 'A variety' with a base diameter of 0.5±0.2 cm, 1±0.2 cm, and 1.5±0.2 cm at an opening angle of 30°, 45°, and 60°, and the branches of the apricot plum 'A variety' with a base diameter of 1±0.2 cm, 1.5±0.2 cm, and 2±0.2 cm.

[0081] (2) Branch pulling: Pull branches at the base, middle, and top of the branches or branch groups until they break. Each test is repeated three times to obtain the theoretical load capacity of branches or branch groups with different base diameters at different opening angles.

[0082] (3) Theoretical number of fruits on branches: Based on the maximum and minimum values ​​of the theoretical load and the average weight of a single fruit, the maximum and minimum number of fruits that a single branch can bear at different opening angles under the same base diameter can be calculated. If this amount of fruit is exceeded, the branch will be very easy to break during the subsequent growth and development, which will affect the yield.

[0083] Table 1 Theoretical number of fruits at different opening angles under different base diameters of branches of 'variety A'

[0084]

[0085] Table 2 Theoretical number of fruits in different opening angles of branch groups with different base diameters of 'Variety A'

[0086]

[0087]

[0088] (4) Fruit thinning: After the fruits fall naturally, thin the fruits at 6cm, 10cm, 14cm and 18cm.

[0089] (5) Fruit appearance quality of apricot and plum branches at different opening angles: 'Variety A' branches with base diameters of 0.5±0.2cm, 1±0.2cm, and 1.5±0.2cm and 'Variety A' branch groups with base diameters of 1±0.2cm, 1.5±0.2cm, and 2±0.2cm at opening angles of 30°, 45°, and 60° under natural growth conditions (without fruit thinning) were randomly selected. The base diameter of branches and branch groups, the fruit size of branches and branch groups, and the opening angle of branches and branch groups were measured every 15 days until the fruit was harvested. Each group of experiments was repeated three times to obtain the actual load of branches and branch groups with different base diameters at different opening angles. After harvest, the appearance quality of the fruits under different treatments was measured.

[0090] (6) Fruit quality at different fruit thinning intervals: Different fruit thinning intervals were used as treatments, and the appearance quality of fruits at fruit thinning intervals of 6 cm, 10 cm, 14 cm, and 18 cm were measured respectively.

[0091] Example 2

[0092] This embodiment provides a technology for improving fruit quality and yield by regulating the angle of apricot and plum branches and the amount of fruit produced, including the following steps:

[0093] (1) Branch selection: The medium-long branches with a length of more than 25 cm were selected for the experiment. A 30 kg tensile force gauge was used to pull the branches of the apricot plum 'B variety' with a base diameter of 0.6±0.2 cm, 1±0.2 cm, and 1.4±0.2 cm at an opening angle of 30°, 45°, and 60°, and the branches of the apricot plum 'B variety' with a base diameter of 1±0.2 cm, 1.4±0.2 cm, and 1.8±0.2 cm.

[0094] (2) Branch pulling: Pull branches at the base, middle, and top of the branches or branch groups until they break. Each test is repeated three times to obtain the theoretical load capacity of branches or branch groups with different base diameters at different opening angles.

[0095] (3) Theoretical number of fruits on branches: Based on the maximum and minimum values ​​of the theoretical load and the average weight of a single fruit, the maximum and minimum number of fruits that a single branch can bear at different opening angles under the same base diameter can be calculated. If this amount of fruit is exceeded, the branch will be very easy to break during the subsequent growth and development, which will affect the yield.

[0097]

[0098] Table 4 Theoretical number of fruits at different opening angles under different base diameters of branch groups of 'variety B'

[0099]

[0100] (4) Fruit thinning: After the fruits fall naturally, thin the fruits at 6cm, 10cm, 14cm and 18cm.

[0101] (5) Fruit appearance quality of apricot and plum branches at different opening angles: 'B variety' branches with base diameters of 0.6±0.2cm, 1±0.2cm, and 1.4±0.2cm and 'B variety' branch groups with base diameters of 1±0.2cm, 1.4±0.2cm, and 1.8±0.2cm at opening angles of 30°, 45°, and 60° under natural growth conditions (without fruit thinning) were randomly selected. The base diameter of branches and branch groups, the fruit size of branches and branch groups, and the opening angle of branches and branch groups were measured every 15 days until the fruit was harvested. Each group of experiments was repeated three times to obtain the actual load of branches and branch groups with different base diameters at different opening angles. After harvest, the appearance quality of the fruits under different treatments was measured.

[0102] (6) Fruit quality at different fruit thinning intervals: Different fruit thinning intervals were used as treatments, and the appearance quality of fruits at fruit thinning intervals of 6 cm, 10 cm, 14 cm, and 18 cm were measured respectively.

[0103] In order to demonstrate the effect of the technology for improving the appearance quality and yield of fruits, experiments were conducted on two varieties of apricot plums, "Variety A" and "Variety B", according to the technology for improving the appearance quality and yield of fruits described in the present invention. The results showed that under the same base diameter treatment, the single fruit weight of branches and branch groups treated with different opening angles increased with the increase of the opening angle. Branch groups with large opening angles help to improve the consistency of fruit size, correct the fruit shape, and improve the appearance of the fruit. Under different opening angles, when the opening angle is 60°, the fruit appearance quality of 'Variety A' and 'Variety B' is the best, the single fruit weight is the largest, and the fruit shape is the most regular.

[0104] As the fruit thinning spacing increases, the average single fruit weight also increases, and the fruit shape tends to be regular. At an 18 cm fruit thinning spacing, the fruit appearance quality is the best, the single fruit weight is the largest, and the fruit shape is the most regular.

[0105] The results are shown in the table.

[0106] Table 5 Appearance quality of fruits of 'Variety A'

[0107]

[0108] Table 6 Appearance quality of fruit of 'variety B'

[0109]

[0110] Therefore, at the optimal fruit thinning spacing of 18 cm, when the branches and branch groups are opened at an angle of 60°, and the number of fruits left on the branches and branch groups of 'Variety A' during the fruit thinning process does not exceed the maximum number of fruits that can be supported when the base diameter of the branches is 0.5±0.2 cm, 1±0.2 cm, and 1.5±0.2 cm, which is 55, 74, and 102 fruits, respectively; and does not exceed the maximum number of fruits that can be supported when the base diameter of the branches is 1±0.2 cm, 1.5±0.2 cm, and 2±0.2 cm, which is 106, 144, and 151 fruits, respectively.

[0111] Ensure that the number of fruits left on the branches and branch groups of 'Variety B' during the fruit thinning process does not exceed the maximum number of fruits that can be sustained when the base diameter of the branches is 0.6±0.2cm, 1±0.2cm, and 1.4±0.2cm, which are 52, 77, and 105 fruits respectively; and does not exceed the maximum number of fruits that can be sustained when the base diameter of the branches is 1±0.2cm, 1.4±0.2cm, and 1.8±0.2cm, which are 101, 129, and 147 fruits respectively.

[0112] In this embodiment, the maximum number of fruits = theoretical maximum load / average single fruit weight.

[0113] The theoretical minimum number of fruits is calculated based on the assumption that the fruits are clustered at the tips of branches / branch groups. However, when thinning the fruits, the fruits will basically be evenly distributed on the branches / branch groups. Under this premise, the number of fruits left during thinning will not exceed the maximum number of fruits.

[0114] Results and Conclusions:

[0115] From the above results, it can be concluded that the present application achieves the technical purpose of improving fruit quality and yield by obtaining parameters. This method can effectively reduce branch breakage and increase yield. It is the best way to achieve the best fruit appearance and significantly increase yield.
