1985年,分析了大面积生产调查和高产试验示范结果,发现夏芝麻单位面积经济产量同生物学产量相关程度较低。许多田块芝麻植株虽然高大,但是始蒴部位太高,植株果轴短,蒴果稀,蒴果少,经济产量低。尤其夏播芝麻,生育季节短,前中期因高温高湿,植株生长发育快,后期又易受低温阴雨影响,植株中上部蒴果质量差,产量低。因此,1985—1986年,我们从播期、密度、施肥量、施肥方法、防病保叶和植物生长调节剂等方面研究芝麻群体的调控方法和效果,形成了配套的芝麻促控栽培技术。1987—1988年在试验示范的基础上,又进行芝麻库源关系的研究,进一步明确了促控能培条件下芝麻的形态指标及生理参数。
In 1985, the results of large-area production survey and high-yield experiment were analyzed. It was found that the economic yield per unit area of summer sesame was lower than the biological yield. Many plots of sesame plants although tall, but the beginning bolt parts too high, the plant fruit axis short, thin capsules, capsules, low economic output. In particular, summer sowing sesame, the breeding season is short, due to high temperature and humidity in the first half of the mid-term, rapid growth and development of plants, the latter vulnerable to low temperature and rainy weather, plant upper capsule quality is poor, low yield. Therefore, from 1985 to 1986, we studied the control methods and effects of sesame populations from aspects of sowing date, density, fertilizer amount, fertilization methods, disease prevention leaves and plant growth regulators, and formed a supporting cultivation and cultivation technology of sesame. From 1987 to 1988, based on the experimental demonstration, the research on the relationship between source and sink of sesame was carried out, which further clarified the morphological index and physiological parameters of sesame under the condition of promoting and controlling cultivation.
