摘  要:
[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。

摘  要:
[Objective] To discuss the measures of safety full heading of rice machine-transplanted seedling in cool-warm rice area. [Method]Effects of variety,seedling age and nitrogen fertilizer dosage of machine-transplanted seedling on the safety full heading of rice transplanting were researched. [Result]During the rice mechanization production of cool-warm rice area,we selected the middle-early cold resistant varieties with the growth period less than 180 d,the seedling age was controlled within 30-35 d; the total net nitrogen was less than 300 kg / hm~2. Percentage of nitrogenous fertilizer postponing should be properly reduced. [Conclusion]Under this condition,safety full heading of rice is ensured,and the target yield is realized.
