水源充裕和适宜稻作的非洲国家,水稻是主要农作物之一,在东非坦桑尼亚,水稻是第二大粮食作物,Txd306是当地种植面积最大的主推品种,农业推广机构试验产量通常为5~6 t·hm~(-2)。为了验证中国水稻无公害高产栽培技术在坦桑尼亚的应用表现,专家组于2016年2—7月进行试验示范,在栽培上采用了合理密植、配方施肥、科学用水和病虫防治等无公害水稻栽培集成技术,理论产量达到9.079 t·hm~(-2),实收产量9.825 t,试验结果表明,在非洲推广水稻无公害高产栽培技术具有较好前景。
Paddy is one of the main crops in Africa with abundant water resources and suitable for rice cultivation. In East Africa and Tanzania, rice is the second largest food crop. Txd306 is the main push-type cultivated area in the country. The output of agricultural extension agencies is usually 5-6 t · Hm ~ (-2). In order to verify the application of pollution-free and high-yielding cultivation techniques for rice in Tanzania, the expert group conducted experiments and demonstrations in February-July 2016. Cultivation of pollution-free rice cultivated with reasonable density planting, formula fertilization, scientific water use and pest and disease control Integrated technology, the theoretical yield reached 9.079 t · hm -2, and the yield was 9.825 t. The results showed that there is a good prospect of popularizing the technology of pollution-free and high-yield cultivation of rice in Africa.
