中稻优培法的内容可概括为:培育适龄的多蘖壮秧,栽插适当的基本苗数,通过肥水管理等技术措施,建成高光效的群体,以达到高产稳产低耗.目前全市开始推广这一栽培体系,1982年的面积达55.56万亩,占全市中稻208.68万亩的22.6%.各地实践证明,增产效果十分显著.如高邮县社两级农技员1982年掌握的249.9亩大麦茬优培法南京11号,有104.6亩超千斤,平均亩产为983.9斤,比193.7亩常规法776.4斤增产26.7%.现着重就两个主要问题探讨如下.
The contents of excellent cultivation method of middle rice can be summarized as follows: cultivating more tillering seedlings of appropriate age, planting the appropriate basic seedling number, establishing high light efficiency groups through technical measures such as fertilizer and water management, etc., so as to achieve high, stable, low production. This cultivation system, in 1982 an area of 555600 acres, accounting for 22.668 million mu of the city’s 20868 acres of rice.The practice has proved around, the yield is very significant.As Gaobu County agency two agricultural grasps in 1982 master 249.9 acres of stubble Youbupan Nanjing on the 11th, there are 104.6 acres of super-kilograms, the average per-mu yield of 983.9 kg, more than 193.7 acres of conventional method 776.4 kg increase of 26.7%. Now emphasis on the two main issues are discussed below.
