1963年我们在水稻旱直播的启发下,认为旱直播整地、播种、灌水合乎科学道理,土壤通气性好,亦很省劲,随即进行育秧技术改革,实行四改;一改秧田翻耕为不耕或少耕;二改秧田施肥撒施为表层铺施、多施;三改秧田水整地、水作畦(床)为旱整地、旱作畦;四改秧田湿润播、水播为旱播、旱覆土。也就是目前所采用的少耕、多肥、通气育秧。这种育秧方法的优点是:秧田整地大为简化,全部过程在旱地情况下进行操作,可穿鞋下田。秧田不翻耕,保持原稻板田状况,地面平整,土层不动,有如场地育秧。地面集中施肥,土表有2—3厘米的肥土,有如盒式营养土育秧,
In 1963, inspired by the direct seeding of rice in the fields, we thought that the direct seeding of the land by dry planting, scientific planting and irrigation, the good aeration of the soil and the saving of soil strength led to the technical reform of raising seedlings and the implementation of the four reforms. Tillage or less tillage; two changed seedling field sprinkling applicator for the surface layer, more facilities; three changed seedling field water preparation, water for trowel (bed) for the dry land, dry tarsal; four sowing wet broadcast sowing, , Dry soil. That is currently used less tillage, more fat, ventilation Yang Yang. The advantages of this method of seedling is: seedling land preparation is greatly simplified, the whole process of operation in the dry land conditions, you can wear shoes Shimoda. Seedling is not plowing, maintaining the status of the original rice paddy field, the ground is flat, the soil does not move, as the site nursery. Concentrated fertilization on the ground, 2-3 cm of soil surface soil, such as box-fed soil nutrition seedlings,
