Practical Technology for Cultivating Ratoon Rice in Rice-fish System

摘要:

再生稻与田鱼共生技术的运用,一定程度上可以解决南方稻作区土地效率不高和劳动力短缺的矛盾,但是,关于再生稻和田鱼共生的技术目前报道不多。本研究探索了在稻鱼系统中再生稻栽培技术的2个核心步骤:留茬高度和主茬密度。结果表明,在长期淹水的稻鱼系统中再生稻的留茬高度应该在40 cm,主茬移栽时选用单本插和宽行窄株(33 cm×17 cm)的株行距可以保证头茬和再生茬产量维持在一个较高的水平。

Abstract:

The use of ratoon rice and fish symbiotic technology, can solve the contradiction of low efficiency of land use and the shortage of labor force. However, few studies about ratoon rice and fish symbiotic technology had been reported currently. A field experiment was carried out to study the key techniques for ratoon rice and fish symbiotic system: stubble height and planting density of rice. The results showed that, 40 cm of rice stubble and 33 cm×17 cm of planting space with single basic seedling per hill was optimized.

Key words: rice and fish symbiotic technology, ratoon rice, rice stubble height, rice hill density
