实验表明“库”容物主要来自灌浆成熟期当时的光合产物(约占70～80％),因此要设法采取一系列相应的措施,保持和提高后期同化器官的同化效率来增加“库”容物的来源。在进行水稻植株对氮的反应研究中表明:在低氮水平下产量主要因“库”容量小而受到限制,但在高氮水平下“库”容量的增加幅度较大,“源”则因群体内的光环
Experiments show that the content of “pool” mainly comes from the photosynthetic products (about 70-80%) at the time of filling and maturity, so try to take a series of corresponding measures to maintain and enhance the assimilation efficiency of late assimilation organs to increase the “storage” capacity The source of things. In response to nitrogen in rice plants, it was shown that the yield was limited mainly due to the low “sink” capacity at low nitrogen levels, but the increase in “sink” capacity was greater at high nitrogen levels and “source” Aura within the group
