Rust-free cultivation method for Baodao banana fruits

Abstract

The invention discloses a rustless cultivation method for Baodao banana fruits. The rustless cultivation method comprises the following steps: (1) spraying a protective solution on fruit surfaces: uniformly spraying a gibberellin mixed solution on the fruit surfaces in a fruit finger flattening period of banana fruit combs; the gibberellin mixed solution is obtained by mixing GA3 and GA4 + 7 according to the mass ratio of 1: 3; (2) spraying a chemical pesticide mixed solution, namely spraying the chemical pesticide mixed solution on the whole banana plant after the banana plant has buds. A protective solution is sprayed on the fruit surface, lignin synthesis can be effectively inhibited, the flexibility and resistance of fruit epidermis cells are improved, and synergistic growth of outer epidermis and inner epidermis of banana fruits is promoted; a compounded chemical pesticide mixed solution is sprayed on the fruit surface, so that the damage of germs to the smooth finish of the fruit surface is prevented, and meanwhile, the stress resistance and disease resistance of the banana fruits are improved; the method can significantly inhibit the formation of rusty spots on the fruit surface of the Baodao banana, improves the commercial performance of the Baodao banana fruit, and has no influence on the fruit yield and internal quality; the method is simple, convenient and suitable for large-area popularization.

Description

technical field [0001] The invention relates to a rust-free cultivation method for fruits, in particular to a rust-free cultivation method for 'Treasure Island banana' fruits. Background technique [0002] The new banana variety 'Baudao Banana' is currently one of the most popularized and most successfully planted banana varieties resistant to Fusarium wilt. It has been planted on a large scale in banana producing areas such as Hainan, Guangdong, Guangxi, and Yunnan. However, during the production process, it was found that if the management is not proper, when the fruit plumpness of 'Bao Dao Banana' reaches more than 7.5%, the surface of the fruit is prone to rust. The fruit rust of ‘Treasure Island Banana’ is striped or irregular, such as figure 1 Shown, have a strong impact on banana fruit commodity performance. According to preliminary research and analysis, the main reasons for the formation of fruit rust are as follows: It is caused by the epidermal cell structure of...

However, during the production process, it was found that if the management is not proper, when the fruit plumpness of 'Bao Dao Banana' reaches more than 7.5%, the surface of the fruit is prone to rust

The fruit rust of ‘Treasure Island Banana’ is striped or irregular, such as figure 1 As shown, it seriously affects the commercial performance of banana fruit

According to preliminary research and analysis, the main reasons for the formation of fruit rust are as follows: It is caused by the epidermal cell structure of the fruit of 'Bao Dao Banana'. Cells are large, irregular in shape, irregular in arrangement, such as figure 2 ; In the rapid growth period (expansion period) of the fruit, the volume of the inner epidermal cells expands far faster than the outer epidermal cells, causing the "mechanical" distortion and deformation of the outer epidermal cells, and the lignification of the cell wall thickens. When this mechanical resistance cannot be offset When the internal turbulent pressure causes cell rupture and death, resulting in the formation of fruit rust in the harvest period of 'Bao Dao Banana' fruit; in addition, excessive summer rain in the south leads to the outbreak of diseases and insect pests, and the fruit surface is easily damaged, which will also promote the aggravation of fruit rust occur

However, although the conventional bagging measures in the banana cultivation process can reduce the invasion of rainwater, it causes the fruit ear to be in a high-temperature and high-humidity micro-environment for a long time, which promotes the growth and reproduction of pathogens, endangers the smoothness of the fruit surface, and promotes the root system to absorb water and transport it to the Fruit, accelerate the expansion of pulp cells, thereby increasing the pressure on the cells near the peel, resulting in the formation of rust on the surface of the fruit; The tree period is too long, the resistance is reduced, and the formation of fruit rust on the surface of the fruit is exacerbated

[0003] After the appearance of rust on the banana fruit of ‘Baodao Banana’, the commercial performance of the banana fruit will decline, which will seriously affect sales and further affect the economic benefits of growers.
