Such practice can comparing with control, the roots in low layer of soil on high-yield field increased twofold, with more branches and gave rise 5-6 order roots, absorption power stronger, active absorption area increased by 57.5%, total amount of roots increased by 83.6%, and roots-top (T-P) increased...

A high-yield comprehensive agrotechiques integrating with ridge-culture, deep-tillage, stratified fertilizer application etc. has been used on 4500 mu in State Farms. Improve soil condition for soybean root extending. Such practice can comparing with control, the roots in low layer of soil on high-yield field increased twofold, with more branches and gave rise 5-6 order roots, absorption power stronger, active absorption area increased by 57.5%, total amount of roots increased by 83.6%, and roots-top (T-P) increased by 34%. Weight of roots of 10 cm top soil layer was correlated with yield of soybean. Under 400 jin/ mu condition, correlation coefficient r=0.783, while over 400 jin/mu, the correlation becomes not linear. The results indieate that improving the root development below 10 cm layer is impotent for high yield of soybean.

高产综合技术采用了垅作、深松、分层深施肥、垅上双条精量播种等综合性措施,全面改善了土壤水、肥、气、热等条件,促使大豆根系向纵深发展。与对照田相比,下层根量增加一倍左右,根茎长度比值提高34%,根系分枝增多,出现了罕见的5—6级根,根系生理活性提高,根系总吸收面积达18.87平方米/株,比对照提高8.43平方米/株,活跃吸收面积提高57.5%,总根量增大83.6%。据相关分析,亩产400斤以内时,10厘米土层表层根量与产量呈显著的正相关,r=0.783。当亩产达400斤以上产量水平时,表层根量与产量不呈直线相关,这表明要获得亩产400斤以上产量应提高10厘米以下根量来夺取更高的产量。

On plate cultures the new blue mold strain Z88(Penicillium sp., isolated from soils by the author in 1988) showed strong antibiosis on the pathogen of rice sheath blight (Rhizoctonia solani). The test revealed that the inhibiting effect on the pathogen was 100% when PSA medium supplemented with above 50×10-2 of volume fraction of Z88 culture filorate. All fungi cells lyseed in 45 h by the addition of sclerotia or agar bearing the fungus into culture filtrate. The cutoplasmic coacervation, plasmolysis and broken...

On plate cultures the new blue mold strain Z88(Penicillium sp., isolated from soils by the author in 1988) showed strong antibiosis on the pathogen of rice sheath blight (Rhizoctonia solani). The test revealed that the inhibiting effect on the pathogen was 100% when PSA medium supplemented with above 50×10-2 of volume fraction of Z88 culture filorate. All fungi cells lyseed in 45 h by the addition of sclerotia or agar bearing the fungus into culture filtrate. The cutoplasmic coacervation, plasmolysis and broken protoplast of the cell coulp be observed under the microscope. The isolate Z88 may also reproduce on the sclerotium and thus made it to be inactive. The germination percentage of rice seeds increased by 6% 21% and the root expansion could be enhanced after dipping the seeds with the culture solution of the strain Z88 for 22 h

青霉Z88菌株(Penicilliumsp.,是1988年作者从土壤中分离出的),经平板培养结果表明:Z88菌株对水稻纹枯病菌有显著的抗生作用.在PSA培养基中加入体积分数为1.5×10-2—50×10-2的Z88菌株培养滤液,体积分数为5×10-2以上对水稻纹枯病菌生长的抑制效果均为100%.在培养滤液中加入水稻纹枯病菌核和带菌琼脂块,45h后菌体细胞全部死亡.镜检水稻纹枯病菌出现细胞质凝聚、质壁分离和原生质带状断裂.Z88菌株还可在水稻纹枯病菌核上生长,使菌核失去生活力.以50—200倍Z88培养液浸泡水稻种子22h,可提高水稻种子发芽率6%—21%,并促进水稻根系分枝

Some characteristics of rice roots were compared between rice grown in paddy field and rice grown by floating method on natural waters. The characteristics of rice root, including adventitious root number per shoot, root diameter, root activity, percentage of active root surface area in rice grown by floating method on natural waters,were closely similar with rice grown in the field, the dynamics of root development were also alike. It showed that the floating culture method is suitable for studying rice root, it would be expected to become a practical method for root study in the future.

对水上种植条件下的水稻根系的一些性状与水田条件下种植时进行了比较。结果表明 ,水上水稻的根系数量、根系分枝特性、根粗等形态指标以及根系活跃吸收面积百分比等生理指标与水田水稻根系表现出较好的一致性 ,而且在整个生育期内的动态变化也呈现出较一致的趋势。说明利用水上种植方法研究水稻根系是可行的 ,能较好地反映较高产量水平的水稻根系在自然环境条件下的生长情况 ,因此有望成为今后水稻根系研究的一条简便有效的新方法
