Example Embodiment

[0018] Soil chemical and biological joint remediation technology for ultra-severe banana soil-borne wilt (banana wasteland), including soil treatment and application of special microbial organic fertilizers, among which,

[0019] Plow the abandoned banana land about 30cm, mix with ammonium bicarbonate (200kg / mu) + lime (100kg / mu) and sprinkle it into the soil immediately, cover the soil with plastic film immediately after raking, and test the soil for Fusarium oxysporum every 2 days The number of bacteria, ten days (when the number of Fusarium oxysporum reaches 10 4 pcs / g) and then remove the plastic film (if you encounter rainy weather, then appropriately delay the time to remove the film), and apply 100kg of Bacillus subtilis ( Bacillus subtilis ) NJN-6 and Trichoderma harzianum with preservation number CGMCC No.3308 (see patent number ZL200910183361.3, antagonistic bacteria for controlling Panama wilt of continuous cropping bananas and its microbial organic fertilizer) ( ...

Abstract

The invention relates to a chemical and biological combined soil remediation method of banana wasteland and belongs to an agricultural intensive production technology. Aiming at the waste soil in which the morbidity of banana soilborne wilt in the current year is larger than 30% and the morbidity of super-serious banana soilborne wilt in the next year is larger than 40%, the method provided by the invention comprises the following steps: treating the soil by utilizing ammonium bicarbonate and lime or stronger ammonia water; killing a certain amount of soil microorganisms; controlling the number of soil fusarium oxysporum (banana wilt pathogenic bacteria) in per g of the soil to be 10<4>; applying a banana specialized-type microorganism organic fertilizer (100kg/mu); regulating the soil humidity; leading the number of externally added beneficial microorganisms in per g of soil to respectively achieve 10<6>-10<8>; and forming an advantageous group in the soil. Through treating the soil by the method, a paddy field with the current-year morbidity less than 10% has the morbidity about 30% in the next year, thus the soil with the super-various banana soilborne wilt is effectively remedied, and is reclaimed for planting bananas.

Description

1. Technical field [0001] The invention relates to a combined soil chemical and biological restoration method for banana wasteland, which is used for the combination of soil chemistry and biology for super-severe banana soil-borne blight (banana wasteland), and belongs to the agricultural intensive production technology. 2. Background technology [0002] Continuous cropping soil-borne blight is the most difficult problem to solve in the production of all economic crops. In production, methods such as crop rotation, soil disinfection, and application of bio-fertilizers resistant to soil-borne diseases are often used to reduce economic losses caused by soil-borne blight. [0003] However, as far as banana planting is concerned, due to the need for typical tropical and subtropical climate conditions, it is difficult to solve it through crop rotation, because there are not many climate regions where bananas can be grown in my country. In 2005, the banana planting area in Hainan P...
