Abutilon theophrasti

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

苘麻，为锦葵科苘麻属苘麻Abutilon theophrasti Medic.，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。

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.

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。

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.

同时通过设置苘麻诱集带，研究诱集棉铃虫（Helicoverpa armigera）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。

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.

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。

Abutilon theophrasti extractions had significant difference on nematicidal activity.

苘麻萃取组分杀线虫活性差异明显。

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.

苘麻（Abutilon theophrasti）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。

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.

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。

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.

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。

Seed of Malva Crispa in stead of seed of Abutilon Theophrasti was used in clinic through investigation.

商品和临床应用调查可知，临床应用的冬葵子均被苘麻子所代替。

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.

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

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。
