黄淮区域芝麻集约化栽培技术模式比较试验OA

To study the yield-increasing effect of intensive cultivation on sesame in the Huang-Huai Region, 7 sesame varieties with good performance in this area, namely Fuzhi 006, Fuzhi 125 and Zhuzhi 21, were selected. With conventional management as the control, a intensive cultivation technology model was set up, including pre-sowing seed treatment with chemicals + control of wilt disease and stem-end blight during the seedling stage + control of leaf spot disease during the flowering and fruiting stage, applying superphosphate and potassium dihydrogen phosphate during the early flowering stage, and spraying potassium dihydrogen phosphate on the leaves 1-2 times during the peak flowering period. The initial capsule height, phenological periods, plant growth conditions, main economic traits, disease resistance and yield of each sesame variety under different technology models were measured. The results showed that compared with conventional management, the sesame growth stage under the intensive cultivation technology mode was shortened (86-98 days), and its economic traits were better (for Fuzhi 125, the tip length of the empty shoot was 8.1 cm, the number of capsules per plant was 104.2, and the weight per plant was 12.2 g; for Fuzhi 9, the initial capsule position was 8.3 nodes and the effective fruit number was 22.1). The control effect of stem tip blight and wilt disease was also good, and the yield was significantly increased (1 848.00-2 187.50 kg/hm 2 ). In conclusion, the application of intensive cultivation techniques can shorten the phenological period, promote plant growth and enhance disease resistance, and increase yield, thereby enhancing the economic benefits of large-scale sesame cultivation.
