摘要
通过引进东北某型号水稻钵苗移栽机,探究了南通市钵苗机插水稻群体发育动态及产量形成优势。结果表明,与常规毯苗机插水稻相比,钵苗机插水稻具有品种选择范围广、秧苗健壮、秧龄弹性大、栽后活棵发苗快、茎秆粗壮、易获得足穗大穗等优点,试验点实收产量646.8 kg/667 m2,比对照增产9.9%。
Through the introduction of a certain type of rice transplanting machine from Northeast China,the population development dynamics and yield formation advantages of pot-seedling mechanical transplanted rice were studied.The results showed that compared with the conventional blanket seedling mechanical transplanted rice,pot-seedling mechanical transplanted rice had wide range of variety selection,strong seedling,elastic seedling age,grow fast after transplanting,sturdy stem,easy to get enough panicle and big spike,the average yield was 646.8 kg/667 m2,increased by 9.9%.
