水稻轻简化高效栽培技术模式试验研究

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/hm~2,增幅6.22%~8.45%,省工120.0~135.0个/hm~2,增收节支5 521.39~8 727.48元/hm~2。结论]这3种模式在生产中具有较好的推广应用价值。

Test Research on the High-efficient Cultivation Technique Mode of Rice

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.
