Description

Technical Field

[0001] The invention relates to a method for cultivating fruit trees, in particular to a method for cultivating breadfruit trees. Background Art

[0002] Breadfruit is a woody food crop of the genus Artocarpus in the family Moraceae. It is also a special tropical fruit tree resource. It can be used as both food and fruit, and is known as the "granary on the tree". Breadfruit flesh is rich in protein, carbohydrates and dietary fiber. It can be eaten after being cooked and can replace food. The yield per mu can reach 1,000 kg during the peak production period, which is a considerable yield. 100 grams of breadfruit powder contains 4.05% protein and 76.70% carbohydrates, while 100 grams of cassava powder contains 1.16% protein and 83.83% carbohydrates. It is a woody food crop resource that can be developed and utilized in southern my country. It is native to Polynesia and the West Indies in the South Pacific and is the main food crop in the area. In addition, the ripe fruit can be eaten in a variety of ways. It can be eaten directly as a fruit, or cooked in soup, sliced ​​and grilled or fried. The flesh is soft and smells like bread. With the development of my country's tourism industry and the improvement of people's quality of life, people's demand for various famous, high-quality and rare special grains is increasing day by day, and healthy and nutritious natural bread will surely become a popular choice. Therefore, the breadfruit industry has a good development prospect.

[0003] At present, breadfruit is still in the stage of moderate industrialization in tropical areas of my country. In the process of promoting planting, it faces some technical bottlenecks, which restricts the development of the industry. Breadfruit grows vigorously and likes light and humid environment conditions. After five years of planting, the tree height exceeds ten meters. Even if it is topped one year after planting, the branches will continue to grow upward. If the growth of branches is controlled by topping every year, it will inevitably lead to a serious reduction in production in the next year. High-altitude layering is generally considered to be the preferred method for dwarfing trees. The seedlings bred by it show obvious dwarfing effects in the first two years of transplanting, but still show vigorous growth in the later period, which makes high-altitude picking and fruit bagging extremely difficult. In addition, typhoons are prevalent in Hainan from June to October, and breadfruit is extremely susceptible to typhoons. How to cultivate dwarfed and high-yield trees and reduce production costs is important for the further development and utilization of breadfruit. Summary of the invention

[0004] In view of this, the present invention provides a method for cultivating a breadfruit tree shape. The present invention first utilizes the natural growth of upper branches to suppress the growth of lower branches, cultivates upper and lower branches, and then controls the top by continuously pruning the upper branches, presses the branches to promote the germination of side branches, and combines formula fertilization to promote branch aging. Finally, a dwarfed and high-yield tree shape is cultivated. It can significantly shorten the initial germination time, increase the branch germination amount, the number and thickness of fruiting branches and the yield per plant, and reduce the height of the first-level branches from the ground, the plant height and the length of the fruiting branches.

Here, "about" generally means that the actual value is within plus or minus 10%, 5%, 1% or 0.5% of a specific value or range.

[0035] The present invention provides a method for cultivating a dwarf high-yield breadfruit tree shape, which specifically comprises the following steps:

[0036] (1) Cultivation of lower branches: After the breadfruit seedlings are transplanted into the soil, 500 grams of 21-6-13 compound fertilizer is applied to the soil. After the 2-3 new leaves of the seedlings have aged, the top 2-3 new leaves are removed to avoid damaging the growth point. The main trunk is bent to an angle of 60-70 degrees to the ground at a distance of 15-20 cm from the top with a branch presser to promote the germination of side buds. After the side buds germinate, the main trunk is restored to an upright position. All the sprouted branches are retained. When the layer of branches closest to the ground grows to 1.0-1.2 meters, the tops are removed and the branches are pressed down with a branch presser at a distance of 15-20 cm from the top to promote the germination of side buds on the branches. When the sprouted side buds grow to 30-40 cm in length, the branches and leaves are sprayed with (0.2-0.4) wt% potassium dihydrogen phosphate solution once to promote branch aging.

[0037] (2) Promote the growth of upper branches first and then control them: When the upper branches grow naturally to 1.0-1.2 meters, promote the germination of lateral buds by pinching and topping. When the sprouted lateral buds grow to 80-90 cm, pinch and topping are performed again. When the secondary sprouted lateral buds grow to 60-70 cm, pinch and topping are performed again. When the tertiary sprouted lateral buds grow to 25-35 cm, spray the branches and leaves with (0.2-0.4) wt% potassium dihydrogen phosphate solution to promote branch aging. After three pinching and topping, a large number of lateral branches (future fruiting branches) can be sprouted from the upper layer, forming a natural control effect on the lower branches.

[0038] (3) Daily pruning in the later stage of tree shape: After the tree is cultivated into an umbrella shape, the overgrown branches should be pruned once a year after the fruit harvest to maintain the overall tree shape. Repeating this process can achieve the effect of dwarfing and high yield.

[0039] In Examples 1 to 3, Comparative Examples 1 to 9 and Effect Examples of the present invention, all the raw materials and reagents used can be purchased from the market.

[0065] Effect example

[0066] The initial sprouting time, the amount of main trunk sprouting, the amount of primary branch sprouting, the height of primary branch from the ground, the plant height, the number of 4-year-old branches, the number of 4-year-old fruiting branches, the length of fruiting branches, the thickness of fruiting branches, and the yield per plant were statistically analyzed (Table 1). The results showed that the embodiment significantly shortened the initial sprouting time, increased the amount of main trunk sprouting, the amount of primary branch sprouting, the number of 4-year-old branches, the number of fruiting branches, the thickness of fruiting branches, and the yield per plant, and reduced the height of primary branch from the ground, the plant height, and the length of fruiting branches. In addition, from the results of Example 2 and Comparative Example 1, it can be seen that the main trunk and primary branch pressing steps are very important, which can shorten the initial sprouting time, increase the amount of branch sprouting, the number of fruiting branches, and the yield per plant. From the results of Example 2 and Comparative Example 2, it can be seen that the step of removing new leaves from the top of the trunk can shorten the initial sprouting time, reduce the height of the first-level branch from the ground, the plant height, and increase the amount of branch sprouting, the number of branches with a 4-year-old tree, the number of fruiting branches, the length of fruiting branches, and the yield per plant. From the results of Example 2 and Comparative Example 6, it can be seen that spraying 0.3wt% potassium dihydrogen phosphate solution on branches and leaves to promote branch aging can shorten the initial sprouting time, the length of fruiting branches, reduce plant height, and increase the number of branches with a 4-year-old tree, the number of fruiting branches, and the yield per plant. From the results of Example 2 and Comparative Example 7, it can be seen that the type of compound fertilizer applied after transplanting also plays a certain role. The 21-6-13 compound fertilizer applied in Example 2 can shorten the initial sprouting time, increase the amount of branch sprouting, the number of fruiting branches with a 4-year-old tree, and the yield per plant.
