无人植保机飞防技术作为一项适应现代植保需求的新型技术,将是传统植保方式的有益补充和革命性升级。为探明无人植保机喷施脱叶剂对棉花的脱叶效果及棉花品质的影响以及研究与筛选适合无人植保机喷洒棉花脱叶剂的喷洒参数和施药技术,国家航空植保科技创新联盟组织了多家联盟单位在新疆石河子开展了4种无人植保机喷施棉花脱叶剂的联合飞防试验。试验结果表明,经过2次施药后,4种无人植保机在设定施药范围内喷施脱叶剂,均能达到良好的脱叶效果;尤其按照每667 m~2喷施1.5 L的药液,脱叶效果优良,药后棉铃吐絮率快速上升。测试结果还表明,无人植保机不同施药处理对处理区棉花的产量因子和纤维品质无明显影响。
As a new technology adapted to the needs of modern plant protection, unmanned plant protection flight defense technology will be a useful supplement and a revolutionary upgrade of traditional plant protection methods. In order to find out the effect of defoliants on the defoliation effect and cotton quality of unprotected plant protection machine and to study and screen the spraying parameters and application technology suitable for spraying cotton defoliant agent on unmanned plant protection machine, Union organized a number of coalition units in Shihezi, Xinjiang carried out four kinds of unmanufactured plant spraying cotton defoliants joint fly-proofing test. The results showed that after two times of application, four kinds of unprotected plant-protecting machines sprayed with defoliants in the range of application, all achieved good defoliation effect. In particular, spraying 1.5L per 667 m ~ 2 Of the liquid, good effect of defoliation, the boll boll speed after treatment rose rapidly. The test results also showed that no pesticide treatment plant on the processing area of cotton yield factors and fiber quality had no significant impact.
