双季超级稻早蘖壮秆强源高产栽培技术研究
A Study on High-yield Cultivation Technique ‘Zaonie, Zhuanggan and Qiangyuan’ of Double Cropping Super Rice
摘要
Abstract
The laws of yield formantion and the cultivation techniques for double super rice were studied from 2006 to 2011. The results showed that the key for double super rice to obtain high yield is enhancing spikelets number per panicle and seed setting rate based on a suitable panicle number and adding the mass accumulation and the nutrition uptake of the late growth stage. The corresponding high yielding cultivation strategy is promoting an early growth and quick tillering in early stage, getting a strong stalk in middle stage and formation a high intensity source in late stage. On this basis, the connotation of the framework ' Zaonie, Zhuang-gan and Qiangyuan' of double cropping super rice was defined, the diagnostic indicators of rice population such as the seedling age of getting enough tillers, nitrogen contents and colour difference of the leaves in early growth stage, big tillers number in primary launch initiationstage, senescent frequency, decline rate of the SPAD in leaves after heading were put forward, the technical indicators such as optimum leaf age for transplanting, density, fertilizer application, water management were presented. Practice has proved, the cultivation technique ' Zaonie, zhuanggan and Qiangyuan' of double cropping super rice were benefit for obtaining a high and stable yield and increasing the fertilizer use efficiency.关键词
