素有盛名的天津小站稻区是我国北方主要稻区之一,在历史上曾发展到154万亩,单产最高达到639斤,高产的1970年水稻面积占粮田总面积的20％,稻谷总产量则占全年粮食总产的37％。但纵观三十多年来小站稻生产的历史,突出地表现出:年度间种植面积相差悬殊,最少年份不足10万亩,与最多年份相比,相差近15倍之多;单产水平也很不稳定,最低年份仅202斤,与最高年份相比,相差达两倍多。出现这些问题的原因,主要是传统的一年一熟耕作制——一季直秧(春稻)既不能适应当地春旱夏涝的自
The prestigious Tianjin Station Rice Area is one of the major rice growing areas in northern China. It has historically developed to 1.54 million mu with the highest yield of 639 kg. The high-yielding rice area accounted for 20% of the total area of the grain crop in 1970. The total output accounted for 37% of the total grain output in the year. However, taking a general view of the history of paddy rice production in the past 30 years and highlighting the fact that the annual acreage varies greatly, with a minimum of less than 10 million mu, a difference of nearly 15 times as much as that of the most years. The level of yield Very unstable, the lowest year only 202 pounds, compared with the highest year, a difference of more than twice. The reasons for these problems are mainly the traditional one-year-a-year farming system - a season of direct seedlings (spring rice) neither can adapt to the local spring drought summer
