摘要
甬优1540作晚稻机插秧栽培表现有效穗多,穗大粒多,结实率高,千粒重大,产量结构协调,稳产性好。根据其生育特性,适合于晚稻机插秧栽培。但分蘖力偏弱,易感白叶枯等细菌性病害。高产栽培措施是适时播插,插足基本苗,科学肥水管理,严防白叶枯病、二化螟等重点病虫害。
Mechanized transplanting late rice Yongyou 1540 had the characteristics of more effective panicle number, large pancle and more spikelets, high seed setting percentage, balanced yield structure, good stablility. nevertheless it also had the disadvantage of weak tillering ability and susceptible to bacterial blight disease. The high-yielding cultivation techniques cover sowing in time, adaquate basic seedling, scientific management of fertilizer and water, prevention and control of rice bacterial blight and chilo suppressalia.
