单氰胺处理对'克瑞森'葡萄物候期的影响
The Effect of Cyanamide Application on Phenological Period of'Crimson'Grape
摘要
Abstract
Using'Crimson'grape(hereinafter referred to as'Crimson')as the experimental material,this study investigated the effects of different concentrations of monocyandiamide and different application time gradients on its phenological phase,providing a basis for the scientific application of monocyandiamide.The results showed that the use of monocyandiamide with a concentration higher than 3.5％or applied later than February 20th had a poor effect on promoting early sprouting,flowering,swelling,and color transformation of'Crimson',and the uniformity was significantly lower than the control,making it unsuitable for use.Applying 0.5％,1.5％,and 2.5％monocyandiamide on January 20th,applying 1.5％and 2.5％monocyandiamide on February 5th,could effectively promote the early germination,flowering,expansion,color change,and high uniformity of'Crimson'grape.Among them,applying 2.5％monocyandiamide on January 20th had the best effect,which could advance the sprouting,flowering,swelling,and color change of'Crimson'by 14,12.91,12.82,and 12 days.It could shorten the duration of sprouting,flowering,enlargement,and color transformation by 3,3.86,3.82,and 4.73 days,which is not only conducive to flower bud differentiation of'Crimson',but also conducive to concentrated agricultural operations,cost saving and efficiency increasing,and should be promoted for use.关键词
