我县推广粮食三熟制以来,粮食年亩产已增长到1603斤。但是,年际变幅大,产量不稳定。1980～1981两年,由于自然灾害的影响,后季稻减产严重,使全年粮食单产下降到每亩1320和1443斤。因此,如何使粮食稳产,力争高产,是我县农业生产中的一个重要问题。在三熟制生产中,因为后季稻占全年粮食总产的比重大、又是大米,而各种矛盾又往往在后季稻激化,所以尤需重视后季稻的生产。这些年来,我
Since the county popularized food three cooked system, the annual output of grain has increased to 1603 kg. However, the annual amplitude is large and the output is unstable. In the two years from 1980 to 1981, due to the impact of natural disasters, the output of post-season rice was severely reduced, reducing the annual grain yield to 1320 and 1443 kg per mu. Therefore, how to make grain stable and strive for high yield is an important issue in our county’s agricultural production. In the three-cropping system, since the latter part of rice accounts for a large proportion of the total grain output in the year and is also rice, various contradictions are often intensified in the latter part of rice. Therefore, it is especially necessary to attach importance to the production of the latter part of rice. These years, me
