钙素是花生的重要矿质营养物质之一,它对花生的生长发育有重要意义。自从1895年汉迪报导了“若无石灰,则花生只长茂盛的蔓和不结仁的空壳”以来,世界不少学者研究了花生对钙素的吸收与利用,有的国家已把施用钙肥作为花生增产的重要措施。国内对钙素的效果进行过一些研究,但对花生吸收钙素后的运转分布特点报导不多。我们于1960—1964年,以放射性~(45)Ca为指示剂,对花生吸收钙素后的运转分布特点进行了初步试验研究,以期为实施农业技术措施提供依据。 Calcium is one of the important mineral nutrients of peanuts, which is of great significance to the growth and development of peanuts. Since Hedi reported in 1895 that “without lime, peanuts only lush vine and shellfish without nuts”, many scholars in the world studied the absorption and utilization of peanut calcium, and some countries have applied Calcium fertilizer as an important measure for peanut production. Domestic research on the effect of calcitonin has done some researches, but there are few reports on the distribution of trait distribution after the peanut absorbs calcium. In 1960-1964, we used radioactive 45 Ca as an indicator to study the initial distribution of Ca (OH) 2 in peanut after its operation distribution, in order to provide the basis for the implementation of agricultural technology measures.
