  change soil properties
     The results indicated that fertilizer∶ soil =1∶400, w/w (treatment G) might be a sensitively fertilizer-soil ratio to change soil properties.

    Barley (rape or green manure) -rice -rice, Wheat-rice and Wheat-cotton. cropping systems have been practised for a long time in the suburbs of Shaghai. Recently a new cropping system, Combined grain with forage cropping designed, Was compared with those cropping systems. The results showed that combined grain with forage and barley-rice-rice cropping systems have much advantage than the others in ecological benefit (efficient of energy and matter discharge) Social effects economic efficient and soil improvement and so on. On the basis of cropping pattern with rice and wheat (or barley) as the main crops, We may adjust rate of barley-rice or wheat-rice cropping system; reduce area of cotton crop by degree; develop special economic crops suitably such as medicinal herbs and spice crops; extend combined grain with forage cropping system vigorously for promoting the development of animal husbandry; set up pluralistic and compound structure of agriculture and realize a good circulation of agricultural ecosystem in the suburbs of shanghai.

    上海郊区现行的麦(油、肥)-稻-稻、麦-稻、麦-棉种植制和我们根据上海大城市郊区的特点而设计的粮饲结合种植制,从生态效益(能流效率和物流效率)、社会效益、经济效益及土壤性质变化等几个方面的综合研究评价结果看,粮饲结合种植制和麦-稻-稻三熟制比麦-稻、麦-棉及其他种植制度有着明显的优越性。因此,上海郊区应该在坚持以水稻和麦类为主体作物布局的基础上,慎重调整麦-稻-稻和麦-稻之间的比例,逐步压缩棉花的种植面积,适当发展药材、香料等经济作物,大力推广粮饲结合种植制,促进多种畜牧业的发展,建立多元多层次的复合农业结构,实现农业生态系统的良性循环。

    Results of examinational study shown that the relationship between contents of available phosphate in soil determined by Olsen's method and the relative yields of crops was fit in with Mitscherlich's modified equation, Ry = A (1-10-cx) .On the yellow paddy soil, C-value in wheat was constant comparatively, it was 0.067 approximately; but that in rice was higher and changed with the nature of soils.

    校验研究结果表明,Olsen法测定的土壤有效磷含量与作物相对产量的关系符合Mitscherlich改良方程R_y=A(1—10~cx)。在黄壤性水稻土上,小麦的C值较为稳定,约为0.067.;水稻的C值较高,且随土壤性质变化。采用复合划级法,分别将土壤有效磷含量<6、6~10、10~17、17~34P-PPm的土壤磷素肥力定为极低、低、中、高四级;小麦相对产量分为<60%、60~75%、75~90%和90~99%四级。根据小麦田间试验,建应了磷肥—产量反应模式,计算了推荐施肥量。麦茬土壤有效磷每增加1P-ppm,在CEC<15和>15的土壤上,应分别施入2.8和7.1ppm-P。

The research results indicated: The H/F ratio in soil humus tended to increase with the prolongation of submer-gence; the soil characteristics changed in different ways in the developmental process of latosol and coastal marsh to paddy soils; the differences between the soils with different origins were significant in...

    The paper deals with the developmental characteristics and classification of two types of paddy soils originated from basalt-derived latosol and coastal marsh respectively in Guangdong province. The research results indicated: The H/F ratio in soil humus tended to increase with the prolongation of submer-gence; the soil characteristics changed in different ways in the developmental process of latosol and coastal marsh to paddy soils; the differences between the soils with different origins were significant in terms of pH value, CEC, ferruginous crystal and ratio of ferruginous crystal and colloid, which reflected the strong influence of original soils. But the differences of characteristics between the soils with same origin but different water regimes were not significant; paddy soil should be an independent soil group, and the distinction of its developmental characteristics and its classification could be based on the soil profile morphology, ratio of ferruginous crystal and colloid, ratio of H/F in humus, pH, total base content, base saturati n etc; the tested soils could be classified into two sub-groups, i. e. lateritic paddy soil and coastal marshy paddy soil. The sub-groups could be further divided into different families according to their water regimes (submergic, periodically waterlogged, gleyed, degleyed etc) .

    本文研究广东省两种不同起源(玄武岩发育的砖红壤和滨海沼泽土)水稻土的发育特征及其分类问题。研究结果表明:土壤腐殖质的H/F比值随淹水时间增长有增大的趋势;砖红壤与滨海沼泽土发育成水稻土的过程中,土壤性质的变化方向不同,不同起源水稻土的pH、盐基代换量、晶质铁以及晶胶率有明显的差别,受起源土壤的影响很大,相反,同一起源不同水型水稻土的性质差异则较小;水稻土应是一个独立土类,土壤剖面形态,铁的晶胶率,腐殖质的H/F比值,pH,盐基总量以及盐基饱和度等可作为鉴别水稻土发育特征和划分土壤类型的依据,供试土壤可划分为砖红壤性水稻土和滨海沼泽土性水稻土两个亚类,每个亚类可按不同水型(淹育、潴育、潜育和脱潜等)划分土属。
