应用不同播种方式和灌溉方法研究了孔穴塑盘育秧实用技术。结果表明：１）土种分播每孔穴４～５粒芽谷，播后浸润为灌，出苗穴率和成苗率较高；土种混播或泥浆播种，虽较省工，但成苗率不如土种分播；播后淹灌或浇灌，易引起烂种烂芽，２）每盘播８０ｇ芽谷以下随播种量增加空穴减少，播种量超过每盘８０ｇ芽谷虽空穴减少，但秧苗素质下降；３）床土混上土重０．５％的ＮＰＫ营养剂有利于培育强壮秧苗，不添加ＮＰＫ营养剂则秧苗较弱，但添加量超过０．５％则易引起“烧种”；４）秧苗－叶－心期喷施３００ｍｇ／ｋｇ的ｐｐ３３３使秧苗矮壮，出很多，生育期趋缓，增加了抛栽秧龄的弹性。 Application of different sowing methods and irrigation methods to study the hole plastic tray seedling cultivation techniques. The results showed as follows: 1) 4 ~ 5 shoots per hole of soil seedling were planted, infiltration was irrigation after sowing, seedling rate and seedling emergence rate were higher; soil mixed or mud sowing, Less than the soil seed distribution; flooded irrigation or irrigation after sowing, easy to cause rotten rotten buds, 2) per panicle sowing 80g buds with the following increase in number of holes to reduce the amount of sowing more than 80g bud Valley although the hole decreases, But the quality of the seedlings decreased; 3) NPK nutrients 0.5% of bed soil mixed with soil weight is conducive to cultivating strong seedlings, seedlings are weak when not adding NPK nutrients, but the addition of more than 0.5% Seed "; 4) seedling - leaf - heart spraying 300mg / kg of pp333 so that the seedlings stout, a lot of growth period slowed down, increasing the throwing planted seedling elasticity.
