Problems solved by technology

At present, the speed of breeding new disease-resistant varieties is still relatively slow. Although the Taiwan Institute of my country has obtained some disease-resistant mutants through the method of mutation selection, some traits do not meet the needs of production, such as long growth cycle and low resistance level. Wait
Genetically modified banana breeding is also underway, but no significant progress has been made
In 2001, the national "863" plan project "Banana Fusarium Wilt Resistance Genetic Engineering" once obtained some transgenic strains. The transformed genes included chitinase, β-3, 5-glucanase, glucose oxidase, etc., but in the field The experiment didn't work out well

Embodiment 1

[0012] Examples of crop rotation:

[0013] 1. Leek variety: Malian leek, purchased from Tangshan Lunan Hehuakeng Seed Breeding Station;

[0014] 2. Banana varieties: Guangfen No. 1 Fenjiao and Brazilian banana;

[0015] 3. Experimental location: a plot with severe banana wilt disease in Wanqingsha Town, Nansha District, Guangzhou City, Guangdong Province;

[0016] 4. Planting and management of leeks: Plow the land before sowing, rake finely after plowing, level the furrows, water enough bottom water, and apply enough base fertilizer. The sowing rate is about 2 kg per acre. Carry out sowing and management according to conventional methods, including fertilizer and water, pests and diseases, harvesting, etc.;

[0017] 5. Planting of bananas: After three years of planting, remove leeks, plant Guangfen No. 1 bananas and Brazilian bananas, and manage them according to conventional measures;

[0018] 6. Investigation on the incidence rate: the incidence rate of Guangfen No. 1 Fe...

[0021] 1. Leek variety: Malian leek, purchased from Tangshan Lunan Hehuakeng Seed Breeding Station;

[0022] 2. Banana varieties: Guangfen No. 1 Fenjiao and Brazilian banana;

[0023] 3. Experimental location: a plot with severe banana wilt disease in Wanqingsha Town, Nansha District, Guangzhou City, Guangdong Province;

[0024] 4. Planting and management of chives: 20 days before planting bananas, sow chive seeds or grow grown chive seedlings, sow and manage according to conventional methods, including fertilizer and water, pests and diseases, harvesting, etc.;

[0025] 5. Planting of bananas: plant Guangfen No. 1 bananas and Brazilian bananas, ensure that there are 30-50 leeks around each banana, and manage them according to conventional measures;

[0026] 6. Investigation on the incidence rate: Brazil banana and Guangfen No. 1 powder banana have an incidence rate of less than 5% for two consecutive years.

[0029] 1. Leek variety: Malian leek, purchased from Tangshan Lunan Hehuakeng Seed Breeding Station;

[0030] 2. Banana varieties: Guangfen No. 1 Fenjiao and Brazilian banana;

[0031] 3. Experimental location: a plot with severe banana wilt disease in Wanqingsha Town, Nansha District, Guangzhou City, Guangdong Province;

[0032] 4. Solid fermentation of Trichoderma: Use rice husk and wheat bran to ferment Trichoderma that can effectively resist the pathogen of banana wilt, and use a serum counting plate to determine the concentration of spores to reach 10 9 cfu / g can be applied;

[0033] 5. Dig holes for planting bananas, apply the solid fermentation product of Trichoderma into the holes, plant bananas and leeks at the same time, ensure that there are 30-50 leeks around each banana, and manage them according to conventional measures;

[0034] 6. Investigation on the incidence rate: the investigation found that the incidence rate of Brazil banana and Guangfen No. 1 powder ban...

Abstract

The invention relates to a novel cultivation technology for preventing and controlling banana fusarium wilt, which is characterized in that mixed planting of banana and Chinese chive is adopted and root exudate or residue putrilage of Chinese chive is used for inhibiting fusarium oxysporum f. sp. Cubense. The cultivation technology for preventing and controlling banana fusarium wilt by taking Chinese chive as a core comprises crop rotation and intercropping. The technology has low incidence for whether plantain or banana (Musa AAA Group Cavendish), even no disease, and is suitable for application in a large area.

Description

technical field [0001] The invention relates to a new cultivation technology, in particular to a new cultivation technology for preventing and controlling banana wilt. Background technique [0002] Bananas are the fourth largest food crop in the world after rice, wheat and corn. According to statistics from the Food and Agriculture Organization of the United Nations (FAO), in the past 10 years, the world's banana planting area has generally shown an increasing trend. In 2007, the planting area was 66.1575 million mu, and the output reached 81.2634 million tons, a record high. In 2007, China's banana harvested area was 4.5825 million mu, ranking fifth in the world; the total output was 7.325 million tons, ranking second in the world. But the development of the industry is facing the devastating threat of Fusarium wilt, the pathogen of Fusarium oxysporum f.sp.cubense. Pathogens invade corms and pseudostems from banana young roots or damaged roots, causing browning of vascula...
