建国三十年来,泾川县在粮田面积由81万亩减少到70万亩的情况下,粮食总产则由7600万斤增加到2亿斤左右,增长了一倍半多。但是还不能满足国民经济迅速发展和人口增长的需要。为在八十年代中把我县农业生产搞上去,现提出以下意见,供讨论和参考。一、目前妨碍农业生产进一步提高的主要矛盾是什么,一定要抓准。打倒“四人帮”后,逐步落实了党的农村经济政策,农业生产得到了发展。但就目前来说,关键问题是土地瘠薄,肥力不足,阻碍了粮食单位面积产量的进一步提高。据实验,每生产100斤小麦,要从土壤中摄取纯氮三斤,磷酸1—1.5斤,氧化钾3斤左右。而我们泾川县土壤20厘米耕层养分含量的平均值是:有机质0.721％,全氮0.0878％,全磷0.165％;每亩含速效氮2.31斤,速效磷 In the three decades since the founding of the People’s Republic of China, the total grain output has increased from 76 million kilograms to 200 million kilograms in Jingchuan County, with the area of ​​grain fields reduced from 81 million mu to 700,000 mu, more than doubling. But it still can not meet the needs of the rapid development of national economy and population growth. In order to promote the agricultural production in our county in the 1980s, the following opinions are put forward for discussion and reference. First, what are the major contradictions that hinder the further improvement of agricultural production so far? After the “gang of four” was overthrown, the party’s rural economic policy was gradually implemented and agricultural production has been developed. However, for now, the key issue is barren land and insufficient fertility, hampering the further improvement of grain output per unit area. According to the experiment, every 100 kilograms of wheat produced, from the soil intake of three pounds of pure nitrogen, phosphoric acid 1-1.5 pounds, about 3 pounds of potassium oxide. The average soil nutrient content of 20 cm soil in Jingchuan County was 0.721% of organic matter, 0.0878% of total nitrogen and 0.165% of total phosphorus, 2.31 kg of available nitrogen per acre, available phosphorus
