浙江省金衢盆地低丘红壤丘陵是浙江省芝麻主要产地之一,总产占全省的42.3％,但由于地形起伏,灌溉不便,加之地处亚热带气候条件下,伏秋旱频繁,长期以来芝麻产量低而不稳。1984,1985两年,我们在红壤生荒地上对义乌黑芝麻采取喷灌、沟灌的方式,研究了芝麻的灌溉制度。实践证明,在灌溉条件下,芝麻喷灌、沟灌的产量比不灌的对照分别增产157.8％和59.9％,粗脂肪含量提高了1.33～1.39％。
The hilly red soil hills in the Jinqu basin of Zhejiang Province are one of the major producing areas of Zhejiang sesame, with a total output of 42.3% of the province’s total. Due to the undulating terrain and irrigation inconvenience, coupled with the sub-tropical climatic conditions, Sesame production is low and unstable. In 1984 and 1985, on the habitat of red soil, we studied the irrigation system of sesame seeds by sprinkling irrigation and furrow irrigation on the black sesame seeds of Yiwu. Practice has proved that under irrigation conditions, sesame sprinkler irrigation, furrow irrigation yield increased by 157.8% and 59.9% compared with non-irrigation control, crude fat content increased by 1.33 to 1.39%.
