为探索化肥单施和化肥与有机肥配施对水稻产量、品质、肥力影响,我们在1984～1986年进行了长期定位试验,其结果如下: 一、试验方法 试验在我院近代冲积物发育的黄泥田进行,土壤属中壤,历年为双季稻绿肥制,其基本农化性状为土壤全氮0.1326％、有机质2.56％、pH6.5,碱解氮81.06ppm、全磷(P_2O~5)0.1126％、速效磷(P_2O~5)20.8ppm速效钾(K_2O)35ppm、缓效钾(K_2O)240ppm。设如下处理:(1)CK、(2)PK、(3)NP、(4)NK、(5)NPK、(6)为处理(5)的50％化肥养分+50％有机肥、(7)为处理(5)的30％化肥养分+70％有机肥、(8)为处理(5)的70％化肥养分+30％有机肥。
In order to explore the impact of single application of chemical fertilizer and chemical fertilizer and organic fertilizer on the yield, quality and fertility of rice, we conducted long-term positioning test from 1984 to 1986, the results are as follows: First, the test method test in our hospital modern alluvial development Yellow soil. The soil was in mid-soil and had double-season paddy green manure over the years. The basic agrochemical properties were 0.1326% of total soil nitrogen, 2.56% of organic matter, pH6.5, 81.06ppm of alkaline nitrogen and P2O5, 0.1126%, P2O5 ~ 20.8ppm 35% K2O and 240ppm K2O. The treatment is as follows: (1) CK, (2) PK, (3) NP, (4) NK, (5) NPK, ) To treat 30% of fertilizer nutrients and 70% of organic fertilizer in (5), and (8) to treat 70% of fertilizer nutrients and 30% of organic fertilizer in (5).
