水稻等蘖穗定向栽培技术,是“三高一稳”栽培法的发展,它通过成穗率的进一步提高来更好地协调穗粒关系,达到双季亩产持续超吨粮的目的。本文在搁田和喷控蘖助穗剂(RCP)联因试验基础上,探讨搁田和喷 RCP 联因对水稻成穗率的影响,为水稻等蘖穗定向栽培提供配套技术。 Rice and other tillers spike oriented cultivation technology, is “three high and one steady ” cultivation method development, it through the further increase of the spike rate to better coordinate spike-grain relationship, to achieve the purpose of double-seeding per mu for continued super tonnage . In this paper, we studied the effects of rice field and spraying RCP on the yield of rice, based on the experiment of RCP, and provided the matching technology for directional tillering of rice.
