近年来,我省有关科研单位,在太湖地区双三熟制早稻栽培中进行了工厂育秧、免耕(浅旋灭茬)、经济施用氮素化肥等单项研究,均获得不同程度的增产降本效果。此项研究试图把这些单项研究成果组装配套,探讨建立高产稳产、低耗高效的技术体系途径及其相应的技术。 试验采用点面结合,大田对比和小区辅助结合的方法进行。按统一设计方案,进行新技术综合应用(以下简称配套区)和常规栽培(以下简称对照区)大田对比试验(表1)。
In recent years, relevant scientific research institutes in our province conducted various researches, such as plant nursery, no-tillage (light-rotation stubble cutting) and economic application of nitrogenous fertilizer in the cultivation of double-cropped early rice in the Taihu Lake region, . This study attempts to assemble these individual research results to explore ways to establish high-yield, low-cost and efficient technical systems and their corresponding technologies. Experiments using point-by-surface, field contrast and cell assisted combination of methods. According to the unified design plan, the new technology comprehensive application (hereinafter referred to as supporting area) and conventional cultivation (hereinafter referred to as the control area) field comparison test (Table 1).
