叶片作为水稻器官建成的物质基础,与水稻群体中光环境的优劣和光能利用率的高低关系密切。而叶面积指数(LAI)的大小直接与水稻最终产量相关,且水稻冠层中光合有效辐射吸收系数与叶面积指数相关性极显著。文章综述了水稻在生长的各个阶段叶面积指数和产量之间的关系,同时通过优化品种、改善栽培措施等手段增加水稻最适叶面积指数,提高水稻产量,以期为高产水稻适宜叶面积指数的预测及合理冠层结构的调控提供理论依据。

人类将普通野生稻驯化为亚洲栽培稻,其农艺性状如株高、落粒性、穗型等发生了重要变化,产量也大幅提高,但许多优良性状如抗逆性等却丢失。长雄野生稻与亚洲栽培稻同属AA基因组,蕴藏了许多生物胁迫和非生物胁迫的抗性基因,被认为是亚洲栽培稻遗传改良的潜在基因库。本文总结了长雄野生稻生物及非生物胁迫抗性、地下茎性状以及其他潜在应用价值性状,包括白叶枯抗性、抗旱性、耐热性、自交不亲和性、氮高效利用以及高产等有利性状。基于长雄野生稻地下茎性状开展多年生稻育种实践的应用研究,对长雄野生稻进行从头驯化的策略进行了探讨,以期为长雄野生稻基础研究及栽培稻遗传改良提供理论参考。

为降低叶丝气流干燥过程中造纸法再造烟叶的损耗,采用正交试验设计方法,研究了气流干燥工序重点工艺参数对造纸法再造烟叶损耗的影响,结果表明:气流干燥入口叶丝含水率以及干燥工艺气体温度是造成造纸法再造烟叶损耗的显著因素,气流干燥热风风速对再造烟叶损耗有一定的影响,气流干燥入口叶丝温度对再造烟叶损耗无太大影响。通过优化工艺参数,降低气流干燥入口叶丝含水率、气流干燥热风风机频率,干燥工序再造烟叶的损耗率降低27.5百分点,烟支中造纸法再造烟叶丝含量提高1.9百分点;同时,烟丝物理质量稳定性提高,烟气焦油量、CO量分别降低0.9,1.2 mg/支,卷烟感官质量变化不大。
