Field experiment showed that coating agent with uniconazole (No2 uniconazole seed-coating agent) could significantly defend cucumber seedlings agaist damping-off, inhibit vertical growth and strengthen in thickness of young seedlings. It could blossom early, significantly increase fruit numbers per plant and yields of early stage and total yield. After coating cauliflower seeds by No2 uniconazole seed-coating agent, the uniconazole coating did not affect emergence rate, reduced damping-off disease incidence, increased stem diameter and fresh weight of seedling underground parts.

大田栽培试验发现：烯效唑包衣能显著防控黄瓜苗期猝倒病，抑制瓜苗纵向生长和促进幼苗加粗，使植株开花提早，包衣后黄瓜单株结瓜数提高，前期产量和总产量均显著提高；烯效唑包衣花椰菜使其出苗时间略有延长，但对出苗率无明显影响，包衣后的幼苗猝倒病发病率显著降低，叶色明显加深，幼苗茎粗和地下部鲜重显著增加，包衣的植株现蕾期提早，花球单重显著增加且表现出一定的增产效应，但试验的两品种间存在一定的差异。

同时，在相关的临床症状和体征的多元线性逐步回归分析中发现，唇色紫暗、舌质紫暗、舌脉曲张、下肢肌力减弱、偏身麻木、头痛，睑下青黑、精神萎靡、舌有瘀斑、言謇失语、面色晦暗、肌肤甲错、瘫肢疼痛不移、肌肤青紫/有瘀斑及脘腹胀满对脑梗塞血瘀证诊断的影响较大；将单因素分析有显著性意义的症状、体征变量，代入贝叶斯逐步判别分析，结果发现唇色紫暗、舌脉曲张、爪甲紫暗、偏身麻木、舌质紫暗、言謇失语、睑下青黑、头痛、瘫肢温度降低、下肢肌力下降等对血瘀证的诊断能力较强，而且在随后的交互检验中也显示了较好的稳定性。

Physiological and biochemical changes of monocotyledonous plant maize (Zea mays L.) were studied and the protective effects of nitric oxide against iron deficiency induced injury were analyzed simutaniously. The plants were grown in monofactor controlled solutions using solution cultural method and the full expanded fourth leaves were used in all of the experiments. The biochemical and the molecular mechanisms of iron induced injury and the protective mechanisms of NO against iron deficiency induced injury were studied.

本实验以溶液培养单因子控制方法研究了单子叶植物玉米在缺铁培养条件下结构、生理、生化的变化以及NO对缺铁植物的保护作用，发现了缺铁胁迫对植物损伤的生理生化及分子机理，以及NO在植物缺铁胁迫下对植物的保护机制，对于植物的缺铁研究和NO在植物中的保护机制研究都有极其的理论和实践价值。

These characteristics of polylactide fiber promote its applications in the areas of fibers and nonwovens, And polylactide fibers can be made to the circular cross section of monofilament or multifilament、trilobal cross-section BCF (can be used for weaving carpets and blankets)、crimp or curly short fiber、the two-component fibers、spunbonded nonwovens and meltblown nonwovens, etc.

这些特性刺激了聚乳酸纤维在纤维和非织造布领域的应用，并且聚乳酸纤维可以制成圆截面的单丝或复丝、三叶形截面的BCF、卷曲或非卷曲的短纤维、双组份纤维、纺粘非织造布和熔喷非织造布等，这使聚乳酸纤维在服装市场、家用及装饰市场、非织造布市场、双组份纤维领域、卫生及医用等领域有潜在的应用前景。
