[目的]研究温凉稻区水稻机插秧安全齐穗的措施。[方法]研究水稻机插秧品种、秧龄、氮肥用量及运筹对水稻机插秧安全齐穗的影响。[结果]在温凉稻区水稻机械化生产中,宜选用生育期不超过180 d的中早熟耐寒品种,秧龄控制在30~35 d,纯氮总量不超过300 kg/hm~2并适当减少氮肥后移比例。[结论]在此条件下,可确保水稻机插秧安全齐穗并实现产量目标。
[Objective] The research aimed to study the safe rice planting rice transplanting seedlings measures. [Method] The research was conducted to study the effects of transplanted rice varieties, seedling age, nitrogenous fertilizer dosage and operation on the safety of rice transplanting. [Result] In the mechanized production of rice in cool and cool paddy area, the middle-early maturing cold-hardy varieties with the growth period of not more than 180 d should be selected, the seedling age should be controlled within 30-35 days, the total amount of pure nitrogen should not exceed 300 kg / hm ~ 2, Nitrogen fertilizer shift ratio. [Conclusion] Under this condition, it could ensure the safe rice planting and achieve the yield target.
