Problems solved by technology

The artificial planting of kiwifruit at home and abroad requires investment in the construction of kiwifruit scaffolding. The disadvantages are high planting costs and cumbersome labor. The labor cost of kiwifruit scaffolding and its construction is not a small expense. increase, and make it difficult for mountainous areas with weak financial resources to grow kiwifruit because of lack of funds, high mountains and steep slopes, and it is difficult to use resources in high-altitude mountainous areas to grow kiwifruit and improve the quality of kiwifruit
[0003] Existing kiwifruit and kiwifruit varieties are almost all cultivated in sheds. This kind of cultivation requires sheds and shelves, which is not conducive to kiwifruit ventilation, light, and easy to get sick. The kiwifruit plants have poor disease resistance and poor fruit appearance and quality. well, affect the taste

Embodiment 1

[0023] a. Soil selection: select or sort out a terraced field with a height of 1.5 meters and a width of 3 meters, arrange it according to the conventional requirements of kiwifruit, and apply base fertilizer;

[0024] B. planting seedlings: the kiwifruit seedlings are carried at 0.4 meters away from the terraced field outer edge (the side without soil); the wild kiwifruit scion of the 800m height of Dawei Mountain, Liuyang City is grafted to Dawei, Liuyang, Changsha by the kiwifruit seedlings Grafted seedlings obtained from wild Actinidia sinensis;

[0025] c. Pruning and cultivating tubes: when pruning in the early spring of the second year, leave 2 main pole branches growing around the tree body, cut off the tip when it grows to 50 cm, let it grow thick naturally, and use it as main pole branches, In the future, regular pruning, thinning of flowers and fruits and vegetables, light and ventilation, fertilization, and prevention and control of diseases and insect pests.

Embodiment 2

[0030] a. Soil selection: choose a terraced field with a height of 2 meters and a width of 3.5 meters, arrange it according to the conventional requirements of kiwi fruit, and apply base fertilizer;

[0031] B. planting seedlings: the kiwi fruit seedlings (with embodiment 1) are carried on the place 0.35 meters away from the terraced field outer edge;

[0032] c. Pruning and cultivating tubes: when pruning in the early spring of the second year, the 3 main pole branches growing around the trunk are left. Routine pruning, thinning of flowers and fruits and vegetables, light and ventilation, fertilization, and prevention and control of diseases and insect pests.

[0033] f. In July every year, lay 2cm deep straw under the branches of the tree to increase the water content of the soil, microorganisms and organic matter, and reduce the growth of weeds.

[0034] g. Harvest when the fruit is slightly reddish brown.

[0035] The entire life cycle of kiwifruit does not require scaff...

Embodiment 3

[0037] Too close to the outer edge of the terraced soil is not conducive to the growth of the root system of the tree body, which is not conducive to the growth of the tree, and too far away from the outer edge of the terraced soil is not conducive to the rational use of land resources. See Table 1 for the effect of the specific distance from the outer edge of the terraced field on the growth of Actinidia jujube tree.

Abstract

The invention provides a frame-free dwarfing culture method for kiwi fruit. Frames are not required in the whole life cycle of the kiwi fruit. The frame-free dwarfing culture method for kiwi fruit specifically comprises the following steps: (1) preparing a terrace with height of 1-2 meters and the width of 2.0-3.5 meters, and planting kiwi fruit seedlings at positions which are distant from the outer edge of the terrace by 0.1-0.5 meter; (2) leaving 2-4 main trunk branches which are radial in four sides during trimming, shearing off tips after the main trunk branches grow to 40-60 centimeters, enabling the main trunk branches to be thickened naturally, then trimming in the conventional mode, and controlling the heights of the trees to be 1.2-1.6 m; and (3) carrying out field management and harvesting in good time. By the method provided by the invention, the cost for artificial planting of the kiwi fruit is reduced by 40% or above, the sugar of the kiwi fruit is increased by 14%, solid matters are increased by 45%, VC is increased by 11%, acidity is reduced by 3%, storage stability is improved, and the quality is improved quite remarkably.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for dwarfing kiwifruit without a frame. Background technique [0002] Kiwifruit is mainly planted in mountainous areas with a weak economy and a shortage of funds. The artificial planting of kiwifruit at home and abroad requires investment in the construction of kiwifruit scaffolding. The disadvantages are high planting costs and cumbersome labor. The labor cost of kiwifruit scaffolding and its construction is not a small expense. Increase, and make the mountainous areas with weak financial resources want to plant kiwi fruit but cannot do so because of the shortage of funds, high mountains and steep slopes, it is difficult to use the resources of high-altitude mountainous areas to grow kiwi fruit and improve the quality of kiwi fruit. [0003] Existing kiwifruit and kiwifruit varieties are almost all cultivated in sheds. This kind of cultivation requires she...
