秧龄对不同类型粳稻品种钵苗机插产量及产量形成的影响
|
摘要
钵苗机插条件下,以中熟中粳稻连粳10号、迟熟中粳稻南粳9108和籼粳杂交稻甬优2640为材料,研究了不同秧龄处理对不同类型粳稻生育期、产量及产量构成、群体茎蘖动态、叶面积指数和物质生产的影响。结果表明,中熟中粳稻最高产对应的秧龄处理为20 d,产量达710.68 kg/667 m~2,而迟熟中粳稻和籼粳杂交稻以秧龄35 d处理产量最高,分别为749.26 kg/667 m~2和849.38 kg/667 m~2。可见,不同类型粳稻品种最高产对应的秧龄不同,在实际生产中,应根据茬口的安排和品种的生育期选择适宜的品种类型,才能充分发挥钵苗机插稻高产、优质、高效的优势。
In order to identify the suitable seedling age of bowl mechanical-transplanting rice, a field experiment was carried out using medium-maturing medium japonica rice Liangeng 10, late-maturing medium japonica rice Nangeng 9108 and indica-japonica hybrid rice Yongyou 2640 as materials in Huaibei area, to study the effects of seedling age on growth period, yield and yield components,tiller dynamics, leaf area and dry matter production of japonica rice. The results showed that, Liangeng 10 has highest yield of 710.68 kg/667 m~2 when the seedling age was 20 days, Nangeng 9108 and Yongyou 2640 have highest yield when seedling age were 35 days,the yield was 749.26 kg/667 m~2 and 849.38 kg/667 m~2 respectively. It can be seen that different types of japonica varieties have different suitable seedling age. In actual production, we should choose the suitable variety types according to the arrangement of stubbles and growth period of varieties, to give full play to the advantages of bowl mechanical-transplanting rice in high yield, high quality and high efficiency.
