菜用枸杞的引种试验与日光温室栽培技术研究 总被引：3，自引：0，他引：3
以广西大叶枸杞为试材,对引入后的生物学特性进行了观察;在繁殖技术方面,比较了一年生和二年生枝条的扦插发芽及生根情况;并用一年生枝条作插条,对扦插后不同覆盖条件下的生根情况、不同部位插条的生根情况及采用不同激素处理后的插条生根情况进行了研究,以探讨枸杞的最适扦插材料和最佳扦插方法;同时,在日光温室条件下对其栽培技术进行了初步探讨。试验结果表明：二年生枝条比一年生枝条生根快,根条数多;扦插后采用地膜覆盖比遮阳网覆盖及不覆盖的生根数量略多,但根长度差异不大;在不同枝条部位的比较中,以中部的插条生根最快、根条数最多;分别用100mg/L、200mg/L、300mg/L的NAA（萘乙酸）和IBA（吲哚丁酸）处理插条,结果以300mg/L的NAA促进生根的效果最好。 相似文献

IBA对兔眼蓝浆果嫩枝扦插生根及内源激素变化的影响 总被引：1，自引：1，他引：0
以兔眼蓝浆果品种‘粉蓝’为试材,研究不同质量浓度(0、3000、5000、7000、9000 mg/L)吲哚丁酸(IBA)处理对‘粉蓝’嫩枝扦插生根及内源激素变化动态的影响。结果表明：兔眼蓝浆果品种‘粉蓝’嫩枝插条生根能力随外源IBA浓度增加而增强;扦插过程中适宜浓度内源IAA及IAA/GA有利于插条愈伤组织和根原基分化形成,高浓度内源GA抑制‘粉蓝’插条不定根的形成;在愈伤组织及根原基形成期ZT含量降低、IAA/ZT升高促进根原基分化形成,而在生根中后期高浓度ZT、低IAA/ZT有利于细胞分裂和不定根伸长生长。ABA及IAA/ABA在生根过程中没有明显变化。 相似文献

珍稀濒危植物毛瓣金花茶扦插繁殖技术研究 总被引：2，自引：0，他引：2
采用5因素4水平正交试验设计,以生根率、生根数、平均根长和根鲜重为扦插生根效果的指标,并构建生根效果指数,评价总的生根效果,研究激素种类、处理浓度、插条在激素中的浸泡时间、插条留叶程度和扦插基质对毛瓣金花茶扦插生根的影响。结果表明,插条留叶程度对生根效果指数的影响最大,扦插基质次之,处理浓度的影响最小,其中插条留叶程度和扦插基质对生根效果指数的影响达到显著水平(p<0.05)。当激素种类为NAA,激素浓度为400 mg/L,浸泡时间为8 h,插条留叶为2片,扦插基质为河沙时,毛瓣金花茶扦插的生根效果最好。 相似文献

近日,笔者在深圳南山、福田、龙岗等多个花卉市场中调查发现,市场经营户经营的多种花卉中,金钱树最受消费者喜爱。据深圳市佳运景观有限公司、中科园林花卉有限公司以及花为媒园林有限公司的几位负责人介绍,与往年相比,今年花卉市场整体销售不容乐观。今年除春节前后一段时间生意比较红火外,直到现在市场都不尽如人意。不过金钱树除外,自去年年底到现在,金钱树的销量一直很火,大的每盆300元以上。 相似文献

苎麻扦插苗特征对其低位分枝扦插苗繁育的影响 总被引：1，自引：1，他引：0
为研究苎麻低位分枝扦插苗特性对扦插苗成苗率及麻苗素质的影响,以期获得苎麻低位分枝扦插苗繁育的最佳方式。以‘中苎1号’、‘湘苎3号’、Tri-1和新品系R057 4个苎麻品种（系）为材料,通过苎麻扦插苗特性（插条粗细、插条长度、插条留叶数、扦插深度、扦插密度）对其低位分枝扦插苗繁育的成苗率及麻苗素质（单株根干重、主茎高度增加量、单株平均分枝数、最低分枝位、最高分枝位和分枝位长）的影响进行研究。试验获得了当前苎麻低位分枝扦插苗繁育的最佳方式：中等粗度（茎基部粗0.6 cm）的插条、5~10 cm的插条长度、4片的插条留叶数、1.5~3 cm的扦插深度和10 cm×10 cm（即100株/m2）的扦插密度有利于苎麻低位分枝苗成苗率及麻苗素质的提高。不同的苎麻扦插苗特性对其低位分枝扦插苗成苗率及麻苗素质有重要影响。 相似文献

香蕉是热带亚热带发展中国家重要的粮食作物和碳水化合物来源。但近年来,香蕉生产受到严重的病虫危害。大多数香蕉栽培品种是三倍体,生长周期长,而且不孕。由于没有种子,给繁殖和育种带来一定的困难。遗传转化技术的发展为香蕉品种的改良提供了一种有效的手段。香蕉的遗传转化方法有电激法、基因枪法、农杆菌介导法等。农杆菌介导法的应用是香蕉品种改良的一个重大突破。香蕉遗传转化的外植体也发展到多种,有原生质体,胚性细胞悬浮系,分生组织,以及横切薄片等。近几年,随着分子生物学的发展,出现了转化效率更高,重复性更好的香蕉遗传转化技术。如农杆菌和基因枪结合法,离心辅助农杆菌介导法、真空渗透技术等。这些新技术新方法的出现,必将推动香蕉产业高速发展。 相似文献

Automobile comfort dynamic simulation is necessary when we predict and evaluate the comfort of a automobile or optimize performance of automobile. The nine DOF vibration model of automobile is established , which acts root mean square value of body in multiple work conditions as comfort evaluation indices. Based on the comfort simulation, the Hongyan 1160 is predicted in the way of comfort. The programmes can be used in many different automobiles . The computational result indicates that the model can simulate vibration of automobile truly. It is significant to research automobile comfort evaluation to optimize performance of automobile and comfort simulation .The computational program can be applied to optimize or simulate which has some reference value. 相似文献

Efficiency of water use of early plantings of sunflower 总被引：4，自引：0，他引：4

Rain fed crop production in Mediterranean environments depends to a large extent on strategies that avoid the intense summer drought. Early plantings of sunflower have given consistently higher yields in such environments, but the basis for such yield increases has not been explored. We conducted two field experiments at Cordoba (Spain) to investigate the effects of an early and a late planting date on the components of water-limited crop productivity; namely, water use (T), water use efficiency (TE) and harvest index (HI) of sunflower. The results were generalized by simulating rain fed sunflower yields, under early (1 January) and late (15 March) plantings, for a 25-year period with the aid of a simulation model of the Ceres type (OILCROP-SUN) which has been validated in Cordoba. Experimental seed yields of early plantings in 1989 and 1996 were 2.0 and 3.0 t ha−1, while late plantings yields were 1.3 and 2.4 t ha−1, for the 2 years. Average simulated yields were 2.7 ± 1.1 and 1.9 ± 0.7 t ha−1 for early and late plantings, respectively. For the 2 years, T of early plantings was higher than that of late plantings, but the response of TE and HI to planting date was not the same in the two experiments. In the simulation exercise, T and TE of early plantings were consistently higher than those of late plantings, while there were no differences in the HI for the two planting dates. We conclude that early plantings of sunflower increase rain fed yields by increasing both T and TE, while the impact of planting date on HI very much depends on the crop water stress pattern, which is quite variable from year to year even in the predictable Mediterranean environment. 相似文献
