摘要
《齐民要术》时代，北方每亩约植桑2．4株（间种禾豆等）。《四时纂要》时代，北方专业桑园每亩约植桑9株～10株。陈■《农书》时代，长江下游专业桑园亩植桑约15株。金元之际或稍早，长江下游专业树桑桑园亩植桑7株～8株；专业地桑桑园亩植桑约240株。明清时期，大体仍如此。到了近代，湖州专业桑园的植桑密度更达每亩1000株上下。亩植桑50株上下的专业桑园，汉唐间未曾大面积出现，金元以后亦未曾大面积出现。唐田令规定的永业田植桑，是20亩植桑50根以上，而不是每亩植桑50根以上。
During the period of Qi-Min-Yao-Shu 6th century AD. ) the density of mutherry-planting was ahout 2.4 trunks per mu (also crops and beans being planted among them) in the northen China, and in the period of Si-Shi-Zuan-Yao 9th century AD. ) the density was about 9 pet mu in special mulberry-garden in this region. In the time of Chen-Fu-Nong-Shu 12th century AD. ) the number of mutherry-planting per mu was about 15 in the special gar den in the lower reaches of the Yangzi River, and in the turn of the Jin and Yuan dynasties or in the pe-riod a little early before that, the density of taller-mulberry garden was 7 ~ 8 each mu, and in the special garden of lower-mulberry the number was about 240, and the situation was like this on the whole during the Ming-Qing dynasties. Up to modem thaes, the density reached 1000 more or less per mu in special mulberry-garden in Huzhou not only The specialmulberry-garden which planted approximately 50 trunks per mu did not emerged exensively during the Han-Tang dynasties, but also after the Jin-Yuan dynasties. So the author thinks that the mu lberry-planting number in Yong-Ye-Tian stiputated by the Land-law of the Tang dynasty is 50 trunks within 20 mu, not over 50 ones per mu.
