Technical analysis of peanut high-yield development tackling with 12982 kg/hm2
In order to further exploit the high-yield potential of peanuts and promote large-scale unit yield through demonstration,the Team of Peanut Cultivation and Physiological and Ecological Innovation Team from Shandong Academy of Agricultural Sciences has been consistently organizing high-yield research since 2013.Yields successively broken through the actual unit yield of 11 250 kg/hm2,11 700 kg/hm2,and 12 000 kg/hm2,with the highest yield reaching 12 982 kg/hm2 in 2023.This paper conducts an analysis of the factors contributing to the high-yield records,including cultivation techniques,climate conditions,and yield components,and compares the input and output.In terms of cultivation technology,the high-yield cultivation technology system integrates single seeds precision sowing,whole process-controlled fertilization,coupling with bio-fungicides,and three-preventions and three-promotions regulatory approach.By fully utilizing the production potential of individual plants and culti-vating high-quality populations to achieve high yields,which provides technical support for the next breakthrough in achieving a unit yield of 13 500 kg/hm2.
