摘要
With consideration of highly-efficient use of natural resources, reducing production cost and construction of high-standard agricultural fields, rice production of good seed+fertilizer investment is reformed on basis of research of smash-ridging technology, and rice smash-ridging ecological and highly-efficient cultivation was pro- posed, namely, smash-ridging based deeply poughing and rotary tillage technology was used to loosen soils deeply, with the depth from 13-15 cm to 26-28 cm. Fur- thermore, after soils softening, seedling slinging or direct seeding was adopted, which is dominated by natural rainfall and supplemented by artificial irrigation. The test proved that the technology help increasing yield and profits over 20%, with chemical fertilizer reduced by more than 10%, and labor cost reduced by 10%. What's more, if the technology applied once, no-tillage or slight tillage is recom- mended in the field, which would maintain original eco-conditions of soils and reach high yield, with energy, water, labor costs reduced in an environment-friendly way.
从自然资源友好高效利用、降低生产成本和建设高标准农田出发.对现行“良种+肥料等投入型”的水稻生产方式提出改革理念.结合粉垄技术研究的现有基础.提出“水稻粉垄生态高效栽培法”.即采用粉垄深旋耕技术翻倍深松稻田耕作层,由常规耕作的13~15cm粉垄增厚至26~28cm,并在回水软土后.实行不耙动土壤的原生态抛秧移栽或直播种植水稻,以天然降水灌溉为主、人工灌溉为辅,保持原田水、肥、土不外流。试验表明,采用水稻粉垄生态高效栽培法.能在化肥减施10%以上、人工劳作减少10%以上的条件下.达到增产、增益20%以上的效果;“水稻粉垄生态高效栽培法”粉垄耕作1次,此后利用构建的粉垄耕作层实行免耕或轻耕,保持粉垄土壤原生态状态,可达到多年持续稳产、增产和节耕、节能、节水、省工、环保的目的。
