绿肥田早稻因无前茬矛盾,近年来过分强调不栽“五一”秧,把移栽期拚命往前赶,给绿肥田早稻的壮苗早发、高产稳产和增产增收带来一些影响。现就我们1973—1978年六年来的调查观察情况来讨论一下绿肥田早稻的适宜移栽期问题。一、从秧苗素质看适宜移栽期什么是适龄壮秧?我们认为,适龄就是“早栽叶不少(最少5叶),迟栽苗不老(不
Due to the lack of contradictions in the early cropping of green manure, over-emphasis in recent years did not planted “51” seedlings. The planted rice fields desperately pushed forward to bring some effects such as early seedling emergence, high-yield and stable yield, and increased yield and income for green manure early rice. Now we from 1973-1978 six years of investigation and observation to discuss the green manure early rice suitable transplanting issue. First, from the quality of seedlings suitable for transplanting What is the age of strong seedlings? We believe that age is "a lot of early planting leaves (at least 5 leaves), late planting seedling not old (not
