高桩再生稻由于穗小粒少,产量不稳定,头季不能应用机收等缺点,严重制约了其在生产上的大面积推广应用。针对这些问题,研究从机收时的留桩高度、碾压带等方面对再生稻栽培技术进行了较为系统的研究。研究结果表明,不同品种在0～5 cm桩高的再生季产量最高,说明在应用机收低桩再生技术进行再生稻生产时,应把留桩高度控制在5 cm内。稻桩适当受轧不影响再生出苗,履带碾压区与非履带碾压区的再生率和再生季产量无显著差异。

With the defects of small size of ears and grains,unstable output and unavailable of machines in the first season,the popularization and application of high stubble ratoon rice in production are seriously restricted.Aiming at these problems,we systematic studied the cultivation techniques of ratoon rice from the stubble height and the rolling zone.The results showed that the yield of ratoon rice was the highest when the stubble height was between 0 to 5cm for all species,indicating that we should control the stubble height in 5cm in the ratoon rice production techniques.Suitable rolling didn’t affect the regeneration of ratoon rice.The regeneration rate and the yield of ratoon rice were without significant difference between rolling zone and unrolling zone.
