播种量对机插钵形毯状秧盘育秧水稻秧苗素质及产量的影响
|
摘要
[目的]探明2种不同行距(25和30 cm)钵形毯状秧盘育秧适宜的播种量。[方法]以粳型水稻品种苏秀867为材料,研究播种量对2种行距钵形毯状秧盘育秧机插水稻秧苗素质、茎蘖动态和产量结构的影响。[结果]随着播种量的增加,2种秧盘株高、黄叶数增加,叶龄、茎基宽、白根数和百株干重下降。25 cm行距和30 cm行距下钵形毯状秧盘播种量分别为100与120 g/盘时,水稻产量最高(9.84和9.80 t/hm~2)。[结论]该研究可为钵形毯状秧苗机插技术的推广应用提供理论依据。
[Objective]To determine the suitable sowing amount of plates in two different sizes(row spacing:25 and 30 cm)with pot-mat seeding.[Method]Taking the japonica rice variety Suxiu 867 as the material,the effects of seeding quantity on the seedling quality,dynamic changes of stem and tillers and yield structure of rice sown by two different size plates with pot-mat seeding were studied.[Results]With the increase of sowing amount,the plant height and yellow leaf number of rice seedlings increased,while the leaf age,basal culm thickness,white root number and dry weight of 100 plants decreased.The highest yield of rice(9.84 and 9.80 t/hm~2) was obtained when the seeding amount was 100 g/tray of 25 cm row spacing and 120 g/tray of 30 cm row spacing respectively.[Conclusion]This study can provide a theoretical basis for the popularization and application of pot-mat seeding and seedling transplanting by machine.
