摘要
[目的]筛选水稻轻简化高效栽培技术模式。[方法]以云粳29号为试验材料，通过田间试验，研究不同的整田、移栽、施肥方式对水稻生育性状、经济性状的影响及其省工、增产、增收效果。[结果]浅旋耕＋机插秧＋控释肥、浅旋耕＋机插秧＋精确定量施肥、深耕＋机插秧＋控释肥3种模式较对照增产稻谷596．40～809．55 kg／hm2，增幅6．22％～8．45％，省工120．0～135．0个／hm2，增收节支5521．39～8727．48元／hm2。[结论]这3种模式在生产中具有较好的推广应用价值。
Abstract
Objective] To screen the high-efficient cultivation technique mode of rice.[Method] With Yunjing 29 as the test materials, field test was carried out to research the effects of land consolidation, transplanting and fertilization mode on the growth characters and economic char-acters, as well as its labor saving, yield increasing effects.[Result] Yields of three modes (shallow tillage +machine-transplanted seedling +controlled-release fertilizer, Shallow tillage +machine-transplanted seedling +precise quantitative fertilization, and deep ploughing +ma-chine-transplanted seedling +controlled-release fertilizer) increased by 596.40 -809.55 kg/hm2 , with the increasing range being 6.22% -8.45% and labor saving being 120.0-135.0 /hm2.Increase revenue and reduce expenditure was 5 521.39-8 727.48 yuan/hm2.[Conclu-sion] These three modes have relatively good popularization value.
