水稻钵苗机插侧位施肥应用效果
|
摘要
[目的]明确水稻品种适宜侧位施肥用量。[方法]通过设置不同氮肥用量进行水稻钵苗穴播同步侧位深施试验,研究其对黄海分公司地区种植的水稻品种生长和产量的影响。[结果]当氮肥施用量与常规相同时,即为225 kg/hm~2,其平均增产3.89%,增收效益1 005元/hm~2。[结论]该研究为黄海分公司水稻钵苗高产高效栽培提供理论依据。
[Objective]To know the appropriate amount of fertilizer of rice varieties.[Method]Setting different amount of nitrogen fertilizer with synchronous side fertilizing technique, the effect of nitrogen fertilizer application rates on the growth and yield of rice varieties was studied.[Result]When the amount of nitrogen fertilizer was the same as conventional, it was 225 kg/hm~2, the average increased yield was 3.89%, and the increased profit was 1 005 yuan/hm~2.[Conclusion]The study provides a basis for high-yield and efficient cultivation of the rice pot seedling in Huaihai Branch.
