上海郊区直播稻于1986年进行试验示范,1989年组织推广,种植面积逐年扩大,到1993年全市推广直播稻面积达42.28万亩,占单季晚稻总面积的14.7％。同时,产量也逐年提高,由1986年亩产450kg左右,迅速上升稳定在500kg以上。1990年平均亩产量为506kg,1991年亩产量为513.63kg,1992年为502.64kg。1993年在气候十分不利的情况下,仍稳中有增,平均亩产量高达528.71kg,创造直播和历史最高水平。
Direct-seeded rice in the suburbs of Shanghai was experimentally demonstrated in 1986, and its organization and promotion in 1989 expanded its planting area year by year. By 1993, the city’s direct-broadcast rice area reached 42.28 million mu, accounting for 14.7% of the total single-season late rice area. At the same time, the output also increased year by year, from about 450 kg per mu in 1986, rising rapidly stabilized at 500 kg or more. The average yield per mu in 1990 was 506kg. In 1991, the output per mu was 513.63kg and in 1992 it was 502.64kg. In 1993, when the climate was very unfavorable, there was a steady increase with an average yield of 528.71kg per mu, which created live broadcasts and the highest historical records.
