通过实验研究,提出了吉19 在我省高产制种技术:实行宽窄行种植,父母本错期播种,母本较父本迟播3 ～4d ,实行双向覆盖,可达增温保墒作用,加强田间诸项管理是保证制种高产关键。
According to the experimental research, it is proposed that the high-yielding seed production technology of Jilin 19 should be planted in wide and narrow rows, and the parents should plant the wrong seeds in time. The female parent should delay the planting three to four days later than the father. Field management is to ensure that the key high-yield seed production.
