农五师82团≥10℃积温3582℃,无霜期171天,春秋两季风大且多,气候复杂,加之土壤粘重下潮,春季地温回升慢,农业生产表现出早播受限,晚播常遇高温天气,形成高脚苗。在这样的自然条件下,栽培必须以“早发、稳长、早熟”为目标,合理确定留苗密度,严格控制主茎高度,综合运用调控技术 82 groups of agricultural five division ≥10 ℃ accumulated temperature 3582 ℃, frost-free period of 171 days, spring and autumn monsoon and more, the climate is complex, combined with the soil sticky tide, spring back to slow temperature, agricultural production showed limited early sowing, late sowing often In case of hot weather, the formation of tall seedlings. Under such natural conditions, the cultivation must take “early onset, stable growth and early maturity” as the goal, rationally determine the density of the seedlings, strictly control the height of the main stem, and comprehensively use the regulation and control technology
