为了进一步探讨不同配肥处理对稻谷产量、品质和土壤理化性质的影响,设置4个施肥处理(无肥、施化肥、施有机肥和施有机肥加化肥)的田间定位化验,定期调查分析不同酉己肥措施对稻谷产量、品质和土壤理化性质的影响,以及它们的经济效益和生态效益。经过几年的定位观察结果,化肥处理稻谷产量开始高,但增产幅度渐减;有机肥加化肥处理增产幅度渐增;有机肥处理稳步增产,尤其遇低温年表现突出(如1988年),并有助于改善稻谷品质(如提高稻谷中蛋白质、脂肪和氮基酸含量)和土壤理化性质。从稻谷产量、品质和经济效益综合考虑,则以有机肥加化肥处理为最佳,既埔产又增收。水稻是北方地区一种高产细粮作物,延边地区适宜种植一季稻,全州水田面积占总耕地面积的16.2％,而稻谷产量却占粮豆总产量的35％左右。因此,广大衣民群众十分重视水稻生产和改士培肥措施。为了进一步探讨不同配肥措施对本地区水稻产量、品质和土壤理化性质的影响,我们从1984～1991年间定期对逐个性状进行了调查分析,在合理用地养地、提高肥料的经济效益和生态效益、保持农田良性循环方面提供了科学依据。
In order to further investigate the effects of different fertilizer treatments on the yield and quality of rice and soil physical and chemical properties, four field tests were conducted to determine the effects of different fertilizer treatments (no fertilizers, chemical fertilizers, organic fertilizers and organic fertilizers plus chemical fertilizers) The effects of unitary fertilization on paddy yield, quality and soil physical and chemical properties, as well as their economic and ecological benefits. After several years of observation, the yield of fertilizers began to increase but the yield was gradually reduced. The yield of organic fertilizer and chemical fertilizers increased gradually. The yield of organic fertilizer increased steadily, especially in low temperature (eg, 1988) Helps to improve rice quality (eg, increasing protein, fat and amino acid content in rice) and soil physical and chemical properties. From the comprehensive consideration of the output, quality and economic benefits of paddy, organic fertilizer and fertilizer treatment are the best, which not only increase production but also increase output. Rice is a high-yield fine grain crop in northern China, while Yanbian is suitable for planting one-season rice. Quanzhou paddy field occupies 16.2% of the total cultivated land while paddy yield accounts for about 35% of the total grain output. Therefore, the masses of people who take part in the production of raw materials attach great importance to the rice production and the measures to improve their income. In order to further explore the effect of different fertilization measures on rice yield, quality and soil physical and chemical properties in the region, we conducted a regular survey and analysis on the character-by-character traits from 1984 to 1991 to raise the economic and ecological benefits of fertilizers on a reasonable land use basis, To maintain a virtuous circle of farmland provides a scientific basis.
