Annual rotation of a winter crop with the summer rice is a common agricultural practice in Chekiang province. The rotation system is in variant with regard to the winter crops. In order to evaluate the effect of different winter crops on the state of soil aggregation, the present study was undertaken. Four green-manuring crops including Astragalus sinicus, Medicago denticulata, Vicia faba and Pisum sativam, two winter grain crops including wheat and barley, and one oil-bearing crop, rape, were chosen for rotation with the summer rice in the field. The soil under experimentation has been developed under cultivation from an alluvial parent material of fine sandy loam. The field had a water-table lying at a depth of about one meter from the top of the soil throughout the year except during rice growing season. As a check for comparison, winter fallow following rice was also included among the field treatments. Experiments are continued through five consecutive crop seasons, including two in rice and three in winter crops. Among the results, the following may have practical significance in evaluating the various systems of annual rotation for rice field: 1. Among the rotating winter crops tested, Astragalus sinicus is most effective in promoting the formation of soil aggregates having 1-5 mm. in diameter which are believed to be beneficial for rice cultivation. Other leguminous crops also show their constructive effect on soil aggregates, but are by far inferior to the Astragalus. To the contrary, soils under winter grains and the rape tend to deteriorate in their aggregation. 2. Close parallel relationship is found between the soil organic matter content and the percentage content of soil aggregates having 1-5 mm. in diameter. 3. The structural units with diameters larger than 5 mm. seem to be different in nature from those aggregates having 1-5 mm. in diameter. For rice soils, such large structural units are believed to be of little practical importance in so far as their fertility status is concerned, since they are to be disintegrated during the cultivation of rice.

四、摘要本試驗的一年轮作制,包括單季水稻与下列冬作的轮栽:紫云英,苜蓿,蚕豆,豌豆,油菜,小麦及大麦。另以冬季休閑作为对照。經过三次冬作,二次水稻(夏作)的轮栽,結果显示: 1.冬季种植一年生荳科綠肥,能够增加土埌中有机質含量。其中以紫云英最佳;苜蓿,蚕豆,豌豆等次之。 2.在水稻与紫云英轮作的土埌中,直徑为1—5毫米的团粒含量有显著的增加。水田中的其他荳科綠肥,如苜蓿,蚕豆,豌豆等,也能維护土埌中的团粒構造,但其效果較差。水田中禾谷类冬作轮栽或油料作物轮栽,对于土埌中直徑为1—5毫米的团粒含量,均有破坏的影响。 3.各輪作区,凡土埌有机質含量較高的,其直徑为1—5毫米的水稳性团粒也比較多;而其他大小的構造單位,和有机質的多少无关。

This research work began in 1977 and has been continued for ten years. Field experiments were conducted in the region of yellow fluvoaquic soil in north China. Data obtained showed that the increase in total carbon of soil through application of different organic manures appeared much more significant than that applied with chemical fertilizers. At the same time, the contents of various humus fractions and the amount of waterstable soil aggregates were also increased greatly by application of organic manures....

This research work began in 1977 and has been continued for ten years. Field experiments were conducted in the region of yellow fluvoaquic soil in north China. Data obtained showed that the increase in total carbon of soil through application of different organic manures appeared much more significant than that applied with chemical fertilizers. At the same time, the contents of various humus fractions and the amount of waterstable soil aggregates were also increased greatly by application of organic manures. The above mentioned phenomena could be observed by micro morphological characteristics of the soil. Correlations between soil treatments and crop yields were quite significant in spite of changes of weather conditions during the past nine years. By assuming that the contents of humus, water-stable soil aggregates, etc. be reliable index of soil fertility, the effect of wheat straw and organic manures on crop yield are much greater than that of chemical fertilizers.
