近年,水稻旱育稀植已成为北方地区优质栽培的主要技术,其优点在于秧苗壮,省水、省种、省时,便于管理,经济效益较高。同时,壮秧是高产栽培的基础,壮秧在栽培后分蘖多,根系发达,能够保证形成足够的穗数,有利于生长。1秧田选择及建设选择地势较高且灌排方便的旱田地,避免在稻瘟病发生严重或含有长效除草剂的地块育秧。秧田面积一般确定为本田插秧面积的1/80~1/100,如稀植时可适当大些。当秧田面积较大时,要做好秧田规划建设,包括引
In recent years, the cultivation of rice has become a major technology for cultivation of high quality in the northern region. Its advantages lie in that its seedlings are strong, water-saving, provincial-type, time-saving, and easy to manage with high economic benefits. At the same time, strong seedlings are the basis for high-yielding cultivation. Strong seedlings have more tillers and more developed root systems after cultivation, which ensures the formation of sufficient spikes and is conducive to growth. A seedling selection and construction Select a high-lying and convenient irrigation and drainage of dry land to avoid the occurrence of severe blast or long-term herbicide in the site of seedling. Seedling area is generally identified as Honda transplanting area of 1/80 ~ 1/100, such as planting can be appropriately larger. When the area of seedling is large, plan and construct the seedling well, including lead
