大面积的改种水稻,是迅速提高淮河以北低产地区粮食产量和提高人民生活水平的主要途径之一。育苗移栽是栽培水稻的主要方式,特别是在春季天气寒冷,水源不足的地区,除水育苗外,旱育苗也是主要的育苗方法。旱育苗在上述自然条件下,可以提前育苗,提前插秧、而且苗期病虫害少,秧苗健壮,能提高水稻产量。例如1958年河北省原沧县专区至五月上旬已育苗10.5万亩,其中旱育苗面积占50%以上。
Large-scale re-planting of rice is one of the main ways to rapidly increase grain output and raise people’s living standards in the low-yielding areas north of the Huaihe River. Seedling transplanting is the main way to cultivate rice, especially in the cold weather in spring, water shortage areas, in addition to watering seedlings, dry nursery seedlings are also the main breeding methods. Dry nursery seedlings in the above-mentioned natural conditions, nursery advance in advance, early transplanting, and seedling pests and diseases, seedlings robust, can improve rice yield. For example, in 1958, Hebei Province, Cangban County area early May has raised 105,000 mu, of which dry nursery area accounted for more than 50%.
