Problems solved by technology

However, long-term continuous cropping will lead to poor growth and development of bananas, aggravation of soil-borne diseases, reduced yield, poor quality, secondary soil salinization, acidification, reduced soil nutrient availability, accumulation of harmful substances, and reduced biological activity. The occurrence of this phenomenon has seriously affected the quality and yield of bananas. Therefore, the prevention and control of continuous cropping obstacles has become the key to the sustainable development of banana production in my country.

Embodiment 1

[0024] 1. Changes in the number of microorganisms after 1 year, 2 years, and 3 years of banana field rotation with sugarcane

[0025] Test location: Zhongwei Village, Shatian Town, Dongguan City; sampling time: October 14, 2013

[0026] The banana planting area experiment is as follows:

[0027] The sample number and description are as follows:

[0028] 1. CK, banana orchard soil that has been continuously growing bananas for 11 years;

[0029] 2. GZ1, the soil after 10 years of continuous cropping of bananas and 1 year of rotation of sugarcane;

[0030] 3. GZ2, the soil after 9 years of continuous cropping of bananas and 2 years of rotation of sugarcane;

[0031] 4. GZ3, the soil after 8 years of continuous cropping of bananas and 3 years of rotation of sugarcane.

[0032] Sampling: 5-point sampling method is used to sample the rhizosphere soil 20-30cm away from the plant, and the depth is about 20cm. After planting bananas or sugarcane for 8 months, the physical and chem...

Abstract

The invention provides an ecological cultivation method of bananas and sugarcanes for overcoming soil continuous cropping obstacles. Sugarcanes are successively planted in a banana field which has planted with bananas for more than three years and shows the continuous cropping obstacles, the ecological cultivation measures such as covering banana fields with sugarcane leaves and returning residual bodies of banana and sugarcane stems to the fields for utilization are combined, and thereby the micro-ecological environment of the soil is effectively adjusted, enrichment of beneficial microorganisms is facilitated, the available nutrient content of the soil is increased, the soil-bore diseases such as banana wilt and the like can be effectively controlled, the physicochemical property of the soil can be improved, and the quality and yield of the bananas and the sugarcanes are improved. Experimental results show that after crop rotation of the bananas and the sugarcanes, the banana yield reaches 3050kg / mu and the sugarcane reaches 7776.7kg / mu and are respectively 32.82% and 12.47% higher than the yields of the fields which are not subjected to crop rotation, the yield is high and stable, and the continuous cropping obstacles can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to an ecological cultivation method for overcoming soil continuous cropping obstacles in banana-sugarcane rotation. Background technique [0002] After continuous cropping of the same crop or crops of the same family, it usually shows poor growth, serious pests and diseases, and serious decline in yield and quality, which is called continuous cropping obstacle. The causes of continuous cropping obstacles are very complex and are closely related to soil conditions, plant biological characteristics, and agricultural measures. The main reasons are that under continuous cropping conditions, species diversity is low, soil microbial flora structure changes, and soil-borne diseases such as Fusarium wilt are aggravated; soil physical and chemical properties deteriorate, soil fertility is deficient, ecological imbalance; and crop autotoxicity. [0003] Banana is a worldwide economic c...
