e0“compared with non-subsoiling,subsoiling at jointing stage achieved the following characters: plant height and ear height decreased by 17.3 cm and 9.0 cm,stem diameter decreased by 2.7 mm,and one leaf less;the increase of LAI before silking was limited,while decrease of LAI after silking was slow;stomatal conductance,intercellular CO2 concentration,transpiration rate,net photosynthetic rate of ear leaves decreased 38%,25.3%,42.5% and 2.0%,respectively;dry matter production was clearly reduced with 1 519.5 kg/ha less before flowering,168.8 kg/ha less after flowering;ear characteristics became bad,i.e.grain number was 100 less,the economic index decreased by 7 percentage,grain yield reduced 1 662.0 kg/ha.”
e1“Zhendan958 was applied in the field experiment.”
