津麦2号亩产500公斤的栽培技术体系

Cuiture System of Yielding 500Kg/mu of JIN Wheat No.2

为解决小麦高产与品种、环境、栽培技术诸因素的关系,本文通过1989～1991年的试验研究,模索出小麦亩产500公斤的综合栽培技术。①建立大面积超500公斤高产示范田,1991年在蓟县有1880亩小麦亩产超过500公斤。②经试验研究明确,本地区亩产500公斤以上产量结构为:亩穗数64～66万,穗粒数26～28粒,千粒重37～38克。③高产栽培措施是:选用秆矮、抗倒、穗多的津麦2号品种;3.3米畦播种20～22行;适量播种;采用重施底肥,氮、磷、钾投入比为1:0.74:0.26和科学运筹水肥及后期“三防”等综合技术。

The reletionship between yield and variety,environment,cultural technique of wheat has been experimented for three years,from 1989 to 1991.The yield of wheat is over 500Kg per mu by using comprehensive cultural practice.It is as follows:①A large area,1880 mu,wheat demonstrative field has been established in J1 county.Its yield was over 500 kg/mu in 1991②The yield construction over 500 kg/mu is:Spike number 640×10~3—660× 10~3/mu,kernel number 26—28 per spike,1000 kernel weight 37—38g.③Cultural measures for high yield are:Adopting JIN wheat Variety NO.2 which is short—stalked,lodging—resistant and multiple—piked.Sowing seeds in 20—22 rows per 3.3m wide.Applying a large quantity of base fertilizer.The ratio of N:P:K is 1:0.74:0.26.Preventing damage from diseases,insects and lodging in the late period.
