四川冬水田区杂交稻抛秧栽培技术研究

Studies on Techniques of Scattered Transplanting Rice Seedlings in the Winter Water Flooded Paddy Fields

本文根据目前四川省农村劳动力结构的变化和青壮年劳力短缺的实际，研究了冬水田区杂交稻抛秧栽培的育秧方式、本田技术等。肯定了冬水田区杂交稻抛栽的可行性，并提出了中苗秧的标准和相应的高产技术，可供指导该项技术在省内推广。

According to the current situation in the changes of labour composition and shortage in the young labours,the ways of nursing seedlings for scattered transplanting in the winter water flooded paddy fields were researched;and the techniques of cultivation and management of hybrid rice in paddy fields were studied.It was proved that it was possible to carry out scattered transplanting in winter water flooded paddy fields.The authors put forward the standard of suitable rice seedlings being 5 leaves and the corresponding high yielding techniques.This research can be a guidance to the popularization of scattered transplanting technique in Sichuan Province.
