为探讨适宜于四川盆地麦(油)茬机插稻的配套育秧技术,以冈优725为材料,研究了秧板处理和育秧方式对机插杂交稻秧苗生长、产量及育秧成本的影响。结果表明,少耕实底双膜育秧处理秧苗矮,根系活力强,单株根数多,用水量少,有利于提高秧龄弹性,适合于机插长秧龄育秧;从育秧成本和产量分析,少耕实底软盘育秧处理育秧成本最低,产量较高,具有节本增效优势。
In order to explore the suitable seedling cultivation techniques for wheat (oil) stubble rice in Sichuan Basin, Gangyou 725 was used as material to study the effects of seedling treatment and planting methods on the growth, yield and seedling cost of hybrid rice. The results showed that seedling growth under low tillage double-membrane seedling cultivation was short, root activity was strong, root number per plant was less, water consumption was less, which was conducive to raising elasticity of seedling age. Farming real floppy disk seedling seedling processing the lowest cost, higher yield, with the advantages of cost-effective synergies.
