Development and experiment of one model manual corn planter for plot experiments
Due to the numerous and scattered breeding units in China,considering the impact of economic indicators such as input-output ratio,we were facing the problem of small experimental areas and uneven distribution in small plots.A simple and practical manual corn plot experimental seeder was developed to address issues such as high labor costs and poor seedling emergence in corn plot experiments.Compared to the community seeders developed and promoted domestically and internationally,this machine has lower technical requirements for operators and was simpler to operate;there were no strict requirements for sowing plots and seed arrangement,making it more practical.It was very suitable for the current situation of maize breeding in China and has good application prospects.
