How is growth promotion and control cultivation carried out for summer sesame? Please give an introduction
Based on the principles of sesame trait correlation, plant stage development, stage nutrient uptake and factor interaction, and through research on supporting cultivation techniques, a technical system for growth promotion and control cultivation of summer sesame has been obtained.
Technical indicators for promotion and control:
(1) Seedling-stage plants are strong but not excessive. Seedling-stage plants are uniform and consistent, the population leaf area index is 0.6-0.8, and the budding and flowering position is below 50cm;
(2) Plants grow rapidly at the middle stage. After flowering, plant height increases by more than 2cm per day, each plant opens 8-10 flowers per day, and the maximum population leaf area index is about 5;
(3) Plants at the late stage are steady and do not senesce early. At the end of flowering, leaves are green, leaf area per plant is 2000cm, the leaf-to-capsule ratio per plant is 20-40cm/capsule, and the population leaf area index is about 3.5, not exceeding 4;
(4) Uniform maturity, robust capsules and full seeds. At maturity, each plant has 50-80 effective capsules, more than 60 seeds per capsule, 1000-grain weight 2.5-3.0g, and seed yield per plant 15-20g.
Main economic indicators: The high-yield trial and demonstration results of this technology show an average yield of 134.6kg/mu (112-154.3kg/mu), an increase of 19.68% (18.5kg/mu) over conventional high-yield cultivation techniques, and an average increase of 63.27% (51.25kg/mu) over traditional planting. The results of large-scale application demonstrations show that for this project's 8.9855 million mu, the average yield was 52.02kg, an average increase of 14.4kg/mu over the 16.25 million mu of non-demonstration areas, with an increase rate of 38.29%. Based on the growth and development process of summer sesame, this technology has developed high-yield morphological indicators and physiological parameters. By promoting material accumulation and nutrient distribution in reproductive organs, it breaks through the conventional high-yield cultivation method of increasing economic yield by increasing biological yield per unit area (per plant). The overall technology is at an advanced level domestically and internationally.
