摘　　要：旨在研究苝二酰亚胺类光敏剂及其与氮磷钾叶面肥复配对油菜生长发育的影响,以1,7-二溴-3,4,9,10-苝四羧基双酐(PDI-2Br)为受体,环己胺为给体制备N,N’-二环己基-1,7-二环己胺基-3,4,9,10-苝二酰亚胺(PDI-4CHA),随后在PDI-4CHA表面包裹纳米硅壳得到PDI-4CHA复合纳米胶囊(光敏剂,PS)。以油菜为试验材料,研究PS最佳喷施浓度,设置CK、0.4%PS、1.2%PS、2%PS、3%PS 5个处理;研究光敏剂与氮磷钾叶面肥W复配(PS&W)处理对油菜生长发育的影响,设置CK、叶面肥W、2%PS、0.4%PS&W、1.2%PS&W、2%PS&W 6个处理。结果表明:成功合成PDI-4CHA复合纳米胶囊;PS喷施浓度在0%~3%范围内,2%PS处理对油菜的促进效果最好,与CK相比,在最后一次取样中油菜SPAD值、干重、鲜重分别提高了21.93%、60.72%、44.93%;PS&W处理对油菜生长影响实验显示,相较于CK、W和PS处理,1.2%PS&W处理在最后一次取样中油菜的鲜重分别增高了161.43%、173.90%和105.46%,干重分别增高了163.98%、173.92%和107.64%,并且复配处理过的油菜的品质均不差于对照处理。该实验证明苝二酰亚胺类光敏剂及其与氮磷钾叶面肥复配喷施对油菜有增效作用。To study the effects of perylene diimide photosensitizers and its compound with nitrogen,phosphorus and potassium foliar fertilizers on the growth and development of rapeseed.N,N’-dicyclohexyl-1,7-dicyclohexylamine-3,4,9,10-perylenediimide(PDI-4CHA)was prepared using 1,7-dibromo-3,4,9,10-perylenetetracarboxylic dianhydride(PDI-2Br)as the acceptor and cyclohexylamine as the donor,and subsequently,PDI-4CHA composite nanocapsules(Photosensitizer,PS)were obtained by coating nanosilica on its surface.Rapeseed was used as the experimental material.Five treatments of CK,0.4%PS,1.2%PS,2%PS and 3%PS were set up to investigate the optimal spraying concentration of PS,and six treatments of CK,foliar fertilizer W,2%PS,0.4%PS&W,1.2%PS&W and 2%PS&W were set up to investigate the effects of the photosensitizer and nitrogen,phosphorus,and potassium foliar fertilizer W complex(PS&W)on the growth and development of rapeseed.The results showed that PDI-4CHA composite nanocapsules were successfully synthesized.2%PS treatment had the best promotion effect on rapeseed when the spraying concentration ranged from 0%to 3%,and the SPAD value,dry weight,and fresh weight of rapeseed were increased by 21.93%,60.72%and 44.93%,respectively,compared with CK in the last sampling.The experiments on the effect of PS&W treatment on the growth of rapeseed showed that,compared with CK,W and PS treatments,1.2%PS&W treatment increased fresh weight by 161.43%,173.90%and 105.46%,and dry weight was increased by 163.98%,173.92%and 107.64%,respectively.What’s more,the quality of rapeseed treated with PS&W was not worse than that of the control treatment.The experiment proved that perylene diimide photosensitizer and its combination spraying with NPK foliar fertilizer had an efficient effect on rapeseed.
