The fertilizer test base on three aspect of grain size、growth velocities 、rate of the green parts, the result present that IBDU multiple fertilizer is bigger grain size and quirkier hydrolyze rapid and more short release period than UF multiple fertilizer, which work easier burning spot on grass leaf of Green lawn; on aspect of growth
肥料对比试验中,进行了颗粒大小、生长速度和绿叶率变化等三个指标的测试,结果指出IBDU技术肥料相对UF技术肥料在沙土环境中具有水解速度快,养分释放周期短等特点,并且大颗粒的IBDU技术肥料容易在水解过程中对果岭草坪产生灼烧性斑点,而对比试验使用的UF技术肥料由于粒径较小相对克服了此点不足;在生长速度和绿叶率变化方面,IBDU果岭均提前于UF果岭达到生长高峰和全绿率,也提前下降生长速率和绿叶比值,试验最终IBDU果岭的日生长量和绿叶率均明显低于UF果岭的数值。

This is due to the different surface properties between a cleavage face and a crystal face. The non-saturated bonds on a crystal face must be readjusted during the growing and the late period. So the growth activation of a crystal face is low at the beginning stage. However, a cleavage face is cleaved artificially and recently. There are many non-saturated bonds on it and these non-saturated bonds can accelerate the growth rate.
其原因是:晶面不同于解理面,晶面上的悬键已在生长过程和后期过程中经过调节达到了新的平衡,所以晶面在初始时期的生长活性很低;但解理面是人为破裂形成的,其上的悬键未能达到平衡,所以解理面的生长活性是很大的,导致其生长速度非常快。

The result showed there existed significant differences among families in seedling growth, dry matter accumulation, leaf shape as well as root parameters at high and low nitrogen levels. Remarkable reduction in seedling height, dry matter accumulation, leaf and root parameters were observed under low nitrogen stress, whereas larger proportion of photosynthesis production was allocated into roots to promote nitrogen absorption. Family variation in seeding growth, leaf and root parameters were increased under low nitrogen stress in comparison with high nitrogen level, which would be benefit to discriminate superior L. chinense families with high nitrogen efficiency. Nitrogen efficiency of different L.
结果表明:不同氮素水平下,马褂木苗的生长、干物质积累、叶片和根系等性状皆存在显著的家系遗传差异;低氮胁迫将显著抑制马褂木苗叶片发育和根系生长,影响苗高生长和干物质积累,但低氮素水平下生产的光合产物则较多地分配至地下根系部分以促进对氮素的吸收利用;与高氮处理比较,低氮胁迫加大了苗木生长、叶片和根系参数等家系遗传分化,有利于鉴别高氮效率的马褂木优良家系。

The proliferative capacity of LEC from human had directly relevance to the age of donor(r=-0.996).Conclusions The formation of lens-like spherules is characteristics of LEC lines in the cultured cells.Under identical conditions,the proliferative rate of LEC from bovine and rabbit is fast than that of LEC from human,but dedifferentiation of LEC from bovine and rabbit is easier than that of LEC from human;LEC from the three species exhibit similar limited growth potential.The proliferative rate of LEC from human has a inversely proportion with age.
