在目前安徽沿江地区不能实现棉花机采的情况下,提出了"植株高度既适于机采也适于人工采收,含絮力适中(不易落花便于集中采收),生育期适中(播种到采收为180天左右),纤维品质及产量性状较优(纤维长度30.0 mm以上,断裂比强度30.0 cN/tex以上,马克隆值5.0以下,籽棉产量3750 kg/hm2以上,衣分在40％左右)"的油(或麦)后直播棉模式的人工采收品种选用策略.旨在促进安徽沿江地区棉花生产稳定发展.

从自然地理条件、环境条件、发展契机介绍宿松县旱稻种植的条件,分析其存在的问题,并提出了相应的对策,以期为宿松县及长江中下游地区发展旱稻生产提供坚实的理论支撑.

介绍了抗虫棉花杂交新品种稼元216 F1近年来在宿松棉区引进试种的结果,表现出稳产、高产、抗逆性强、适应性广等特点。从合理密植、科学施肥、全程化控、适时打顶、防止早衰等方面总结了稼元216 F1的高产栽培技术。

主要总结了生产中棉花早衰的成因,并提出了防治棉花早衰的措施,以为棉花高产提供参考。

The field efficacy trial of dinotefuran 20% SG was conducted to confirm the control effect on Lygus lucorum Meyer-dur.[Results] The results showed that the efficacy of dinotefuran 20% SG at 450,300,225,150 g a.i./ha and malathion 50% EC at 750 mL a.i./ha were 100,80,81.82,75 and 50% respectively against L.lucorum Meyer-dur on the first day after treatment,the efficacy were 100,100,94.29,80.25 and 46.45% on the third day,and 100,95.15,95,80.11 and 41.86% on the seventh day.[Conclusions] Dinotefuran 50% SG has advantages of readily availability,persistence and safety on cotton,which is an ideal pesticide in protecting cotton from L.lucorum Meyer-dur,the usage is 150-225 g a.i./ha in medium to light years,while 225-300 g a.i./ha in medium to large years

总结了2010年宿松县棉花高产创建活动工作的主要措施和成效,以期提高当地的棉花种植水平。

以几种新型农药为材料,研究了其不同剂量防治棉花苗、伏蚜的效果及其配套应用技术。试验结果表明,25%吡蚜酮WP50ppm、20%喹硫磷EC150ppm、40%毒死蜱EC300ppm和1.8%阿维菌素EC6ppm药后1-15d防效分别为72.3%-99.4%、81.3%-99.4%、62.7%-98.8%和47.1%-96.8%,其总体防效相当于或略优于对照药剂50%甲胺磷,是高毒农药的理想替代品种,且对棉花生长和棉田天敌较安全。
