摘要
马铃薯(克新1号)块茎产量在38 718 kg／hm2水平下,平均每生产1 000 kg块茎,植株需吸收Ca 1.739 kg,Mg 1．195 kg．S 0．504 kg,比例为1．00:0．69:0．29。5月2日～5月16日(孕蕾～开花),是植 株吸收Ca,Mg,S最多的时期,占各自总吸收量的36．31％,38．30％,33.62％。收获时,植株吸收的Ca,Mg主 要贮存在叶中,S主要贮存在块茎中。
In order to produce every 1 000 kg tubers under the level 38718 kg/hm^2 of potato （Kexin No. 1） tuber yield, 1. 739 kg Ca, 1. 195 kg Mg, and 0. 504 kg S should be assimilated by the plants. The proportion was 1.00 ： 0.69 ： 0.29. Ca, Mg and S were mainly assimilated in the period from March 2nd to 16th, which were 36.31%, 38.30% and 33.62% of the total value of assimilation. At harvest time, Ca and Mg were mainly stored in leaves; S was mainly stored in tubers.
