我们去年于水稻抽穗前后在本场范围内多次进行田间调查,年底参加省里的一些会议又了解到我省中北部水稻生产的一些情况与我们调查结果相一致,足以说明1979年某些地方和单位水稻减产的主要原因是施肥不当,尤其是氮素化肥施用过多。从表一可以看出,一九七九年的气候条件是较好的。年平均气温和对水稻抽穗扬花结实影响较大的七、八、九月的月平均气温以及极端最低温度都比七七、七八年要高,相对湿度也略大于七七、七八年。可是七九年的水稻产量下降了,表一所列两个生产队, We conducted field surveys several times before and after rice heading in this field last year. At the end of the year, we attended some meetings in the province and learned that some of the rice production in the central and northern part of our province is consistent with our findings. This shows that in some places in 1979 And the main reason for the unit of rice production is improper fertilization, especially excessive nitrogen fertilizer. As can be seen from Table 1, the climate conditions in 1979 are better. The average annual temperature and the greater impact on the heading and flowering of rice have a greater monthly mean temperature in July, August and September and the extreme minimum temperatures are higher than those in the seventy-seven or seventy-eight years. The relative humidity is also slightly larger than in the seventy-seven or seventy-eight years. However, the output of rice in 1979 dropped. For the two production teams listed in Table 1,
