Sesame mechanical planting techniques based on combination of agricultural machinery and agronomy.

According to the technical difficulties of sesame mechanical planting , based on the idea of the combination of agricultural machinery and agronomy , the information collection of sesame mechanical planting was carried out in China. 7 sets of medium and small - sized practical mechanical equipment suitable for sesame planting were introduced , selected and reformed , and key technologies of sesame production mechanization were proposed. Results of mechanical planting showed that suitable row spacing of sesame machine sowing was 33. 3 - 4 0 . 0cm , appropriate seeding rate was 0. 3kg/666. 7 m². The practical herbicide was 99% acetochlor before seedling after sowing. The highest yield was 151. 0kg/666. 7 m² , which occurred in the treatment of no - tillage , machine sowing and base application of compound fertilizer 25kg/666. 7 m² and topdressing urea 5kg/666. 7 m². The yield increased 16. 25% with exempting tillage , machine sowing and straw returning treatment , compared with no - straw returning treatment. The yield of chemical thinning and singling was close to the artificial thinning and singling , but the chemical thinning and final singling could save the labor cost more than 100yuan/666. 7 m² and could effectively control the weeds at seedling and seedling shortage. Nine times sesame mechanical planting and high - yield demonstration were carried out between 2009 and 2012. The average yield was 116. 3kg/666. 7 m² and increased by 34. 2% compared with the non - demonstration areas. [ABSTRACT FROM AUTHOR]
