通过对基质育秧、硬地育秧、壮秧剂营养土育秧和无纺布覆盖育秧等新型育秧技术在陕西省西乡县机械化插秧栽培中的观察研究表明:硬地秧床具有节省秧母田、便于操作的优点,但灌水次数多,保墒能力差;常规秧床需做秧母田,播种时费工费时,但排灌水方便,灌水次数少;塑料拱棚和无纺布对秧苗素质影响不大;基质营养土和壮秧剂营养土对提高秧苗素质作用显著,效果明显优于常规营养土。建议农户小面积分散育秧可采用硬地秧床+基质(壮秧剂)+无纺布;合作社或种粮大户育秧面积较大时宜采用常规秧床+基质(壮秧剂)+无纺布(塑料拱棚)。
The observation and research on new seedling raising techniques such as seedling raising of seedling, hard seedling raising, strong seedling raising agent nutrition soil-growing seedling and non-woven fabric covering seedling cultivation in mechanized planting and transplanting cultivation in Xixiang County of Shaanxi Province showed that hard seedling bed has the advantages of saving seedling field, The advantages of convenient operation, but more irrigation times, poor soil moisture capacity; conventional seedbed need to do seedling field, sowing time and labor costs, but convenient irrigation and drainage, irrigation less; plastic shed and non-woven fabric quality little impact on the seedlings ; Nutrition substrate of soil nutrition and strong seedling enhance the quality of seedlings significantly, the effect is better than conventional nutrition soil. It is recommended that small area of scattered farming seedlings can be used hard seedling bed + matrix (strong seedling agent) + non-woven fabrics; cooperatives or grain growers large seedling should use conventional seedbed + matrix (strong seedling agent) + non-woven Plastic Shed).
