近年来,向日葵作为一种新兴的油料作物得到了较快的发展。不少人对其生育规律及生理特性作了大量研究,但有关向日葵瘦果在灌浆期间干物质积累的研究却涉及还不多。在其它作物上灌浆规律的研究对生产起到了一定的积极效果。为此我们于1983年在向日葵上进行了这方面的初步研究,从中摸索了向日葵瘦果灌浆充实的一般规律,结果如下。 In recent years, sunflower as a new oil crop has been rapid development. Many people have made a lot of research on their reproductive laws and physiological characteristics, but the research on the accumulation of dry matter during the filling period of sunflower is not yet involved. The research on the law of grouting on other crops has played a certain positive effect on the production. To this end, we conducted a preliminary study in this field on sunflowers in 1983, from which we explored the general law of enrichment of sunflower achenes. The results are as follows.
