Method for guiding banana low-position oriented budding and fruit bearing

Abstract

The invention belongs to the technical field of banana cultivation, and relates to a method for guiding banana low-position oriented budding and fruit bearing. The method comprises the steps that according to the growth period and morphological development characteristics of banana varieties, banana plants subjected to field planting or banana plants with suckers grow for 5 months or 8 months, thebanana plants with true stem flower buds reaching the specific development stage are selected, a bud guide mouth cavity is formed in the side of a pseudo stem of 130-160 centimeters off the ground and above the buds of the tops of the true stems, a bud guide plate is installed in the cavity, and a cavity mouth is sealed with sealing film. When the buds are pulled out of the cavity, proliferativetissues of true leaves of the buds which are not cut off when the mouth cavity is formed in the front ends of the buds are cut, prevention piles are placed on the sides, away from the cavity mouth, ofthe banana plants and the banana plants and the prevention piles on the upper and lower ends of the cavity mouth are respectively tied by straps. The method can achieve the lower-position budding andthe oriented fruit bearing of the bananas, reduce the labor intensity and difficulty of the agricultural operation of the relevant nursing technology of the banana budding fruiting bearing period, improve the labor efficiency and the production benefits, and be especially beneficial for the harvest of the bananas.

Description

technical field [0001] The invention belongs to the technical field of banana planting, and in particular relates to a method for guiding banana low-position directional budding and fruiting. technical background [0002] Bananas are identified as the fourth largest food by the Food and Agriculture Organization of the United Nations. There are more than 130 countries that cultivate bananas in the world, mainly distributed in tropical and subtropical regions within 30° of latitude north and south. Banana is also an important tropical fruit suitable for tropical and subtropical cultivation. my country’s banana production accounts for 60% of the total tropical fruit production. The banana planting area is as high as more than 400,000 hectares, with an annual production volume of more than 12 million tons and an annual consumption of more than 13 million. Ton. Banana planting has high economic benefits and has become an agricultural pillar industry in Guangdong, Guangxi, Hainan...

Problems solved by technology

These biological characteristics of bananas lead to the following problems in the production process: First, bananas budded at high positions face the risk of yield reduction or even failure due to lodging and breaking caused by high center of gravity and wind damage

In the production of bananas in our country, it is often necessary to take preventive technical measures such as pull ropes, stakes, and erecting frames, which not only increase cost input, but also increase agricultural labor work, and are often unfavorable to agricultural operations, especially hindering mechanized operations

Second, technologies such as pad wiping, spraying and bagging, and non-destructive harvesting have received more and more attention and been continuously promoted and adopted in my country’s banana production. The application of these technologies can increase banana production, improve fruit quality, and enhance fruit commerciality and safety. Market competitiveness improves the economic benefits of production, but the high bud position and random fruit-hanging direction of bananas restrict the application of these technologies, such as increasing the difficulty and intensity of operational labor in the application of these technologies, increasing production costs and reducing production costs. labor efficiency

[0004] So far, the prior art method of dealing with the above problems: one, selection and breeding of dwarf banana varieties, which is an effective way to reduce the height of banana buds, but in view of the lack of good dwarf germplasm of bananas and the selection of bananas There are limitations in the method. Among the bred banana varieties, there are very few good dwarf varieties. In addition, banana dwarf varieties often show a decline in fruit yield due to reduced biological production, and it is difficult to achieve both excellent comprehensive performance and meet production needs.

The second is to control the dwarfing of banana plants by spraying growth regulators during the cultivation process. This is also an effective technical method to reduce the height of banana buds, but it also has the problem that dwarfing causes a decrease in biological yield but a decrease in fruit yield. Moreover, the technical operation requirements are relatively high, and there are negative effects such as excessive dwarfing caused by improper operation, failure out of control or excessive control. In addition, food safety and environmental protection problems of chemical residues are also faced

The third is that at present, the operations of padding, bagging and tying are mainly manual operations, that is, by climbing ladders, which is not only labor-intensive, but also low in efficiency, and there is a risk of falling off the ladder.

Fourth, despite the emergence of technologies such as bagging devices for mechanized operations, spraying machines, and mechanical harvesting, the unfavorable restrictions on the technology from the high position and random direction of banana fruit hanging obviously exist, such as increasing the complexity of machine design. and manufacturing costs, ease of operation and high efficiency in reducing tooling processes
