苘麻

苘麻，为锦葵科苘麻属苘麻AbutilontheophrastiMedic.，又名白麻、青麻、野苎麻等，在全国分布广，其天然资源极为丰富。

The natural resource of Abutilon theophrasti Medic , is rich , distributed in all of China .

同时通过设置苘麻诱集带，研究诱集棉铃虫（Helicoverpaarmigera）机理，优化诱集方法，探寻利用苘麻防治棉铃虫的生物防治措施。

Meanwhile , Abutilon theophrasti trapping band is set to study the mechanism of the Helicoverpa armigera , optimize attracting methods and explore the biological control measures using Abutilon theophrasti to prevent cotton bollworms .

初步生物活性测试表明：化合物4c，5a，5b，5c在有效成分75g/hm2剂量下对苘麻、马刺苋、凹头苋等双子叶杂草表现出90%以上的防效。

The pri-mary bioassay results showed that compounds 4c , 5a , 5b and 5c exhibited control efficacy of more than 90 % against Abutilon avicennae , Portulaca oleracea , and Amaranthus spinosus at 75 g / hm2 .

苘麻（Abutilontheophrasti）是棉田分布广泛的杂草，在与棉花竞争资源影响其生长同时，又可以对棉铃虫产生极强的诱集效果，是极具开发潜力的一种生物防治材料。

Abutilon theophrasti , which is a distributing weed abroad in cotton field , can not only effect the growth of cotton , but also bring very strong attractive effect to cotton bollworms , so it is a very potential creature prevention material to exploit .

复合生物酶处理对苘麻木质素去除的影响

苘麻萃取组分杀线虫活性差异明显。

Abutilon theophrasti extractions had significant difference on nematicidal activity .

翠绿色苘麻植株诱集效果明显好于深绿色。

In the amount of cotton bollworms eggs to different circumstances , the attracting effects of emerald plants are significantly better than dark green .

本试验以果园杂草马唐、金狗尾、反枝苋、苘麻、藜的种子为试材，研究了多效唑对杂草种子发芽的影响；

The effects of paclobutrazol on the germination of crab-grass , green amaranth , golden foxtail , stamp weed and bacon weed seeds was studied .

两者都表明滴灌后苘麻适应较好，有成为棉田主要杂草的潜能。

And they both indicated that Abutilon theophrasti adapted preferably by drip irrigations , and will have the latent to be the main weeds in cotton field .

主要研究结果如下：1.苘麻不同溶剂提取物对南方根结线虫的生物活性存在显著差异。

The results could be summarized as follows : 1 . The Abutilon theophrasti Medic extractions from different solvent have significant difference in meloidogyne incognita nematicidal bioactivity .

通过生物活性追踪的方法首次对苘麻甲醇提取物水萃取组分中的对南方根结线虫具有活性的物质进行了系统研究。

It was the first system research on the meloidogyne incognita nematicidal activity substance in Abutilon theophrasti water extraction of MeOH-Ext using the method of biological activity tracking .

滴灌前期苘麻占总种子库比例有增大趋势，但滴灌处理8年时种子库为0。

The ratio of Abutilon theophrasti increased in the former stage of drip irrigations , but seed banks became 0 when the drip irrigations had been applied for 8 years .

⑵综合分析表明苘麻是利用棉铃虫的视觉定向行为进行诱集棉铃虫产卵的，棉铃虫在苘麻植株上产卵有利于孵化的幼虫取食。

Comprehensive analysis shows that abutilon trap cotton bollworms oviposition by using visual orientation behavior of Helicoverpa armigera , cotton bollworm larvae are beneficial to feed on the Abutilon theophrasti plants oviposition .

应用苘麻时要在其成熟时严控种子扩散，以防苘麻对棉花生长产生负作用。

The seeds of Abutilon theophrasti should be controlled grimly at its maturity period when it is applied , which is to prevent Abutilon theophrasti bringing negative effect on the growth of the cotton .

同时棉铃虫产卵高峰期刚过要对诱集带和距诱集带较近的棉区进行药物防治，冬季要对种植苘麻诱集带棉田的蛹进行灭杀。

Meanwhile medicine prevention should be carried out at the trapping band and the cotton area near to the trapping band when the oviposition peak period of cotton bollworms is just over . And the pupa should be destroyed at the trapping band areas in winter .
