我们一九七二——一九七四年的研究结果指出,甜菜喷施核苷酸类物质——“702”,有明显的增产增糖效果。通过研究,对喷施时期、浓度以及对甜菜的生育营养代谢的影响有了进一步的认识。可是,“702”喷施到甜菜叶片上后,起作用的因素是什么,是怎样起作用的?对此,今年我们在过去研究的基础上,着重进行了试验研究,现将结果总结如下。试验设置(一)试验地规划和处理本试验在本院农场进行,供试品种为
According to the results of our study from 1972 to 1974, the application of sugar nucleotide “702” to sugar beets has obvious effect of increasing sugar yield. Through the research, we got a better understanding of the effects of spraying period, concentration and the nutrition and metabolism of sugar beet. However, “702” sprayed onto the beet leaf, the factors that play a role, is how to play a role? In this regard, we have in the past based on the study, focused on the pilot study, the results are summarized below.
