Title: Study on the Characteristic of Potassium Absorption and Low Potassium Endurance Mechanism for Different Genotypes Maize
Abstract: This article studied 12 different genotypes maize systemically by seedling depletion and potted plant,soil culture experiment with low Potassium in soil.The results were that seedling depletion experiment showed Nong-da86 was best in absorbing and accumulating Potassium and sweet corn was the worst.In soil seedling depletion ex-periment,the ratio of absorbing mineral Potassium was highest,the next slow-release.Potassium and the lowest was available Potassium.Soil culture experiment showed that Nongda86 having high absorbing Potassium could still ab-sorb and accumulate more Potassium to meet the need of self growth and to gain more yield,and it was a variety which could absorb Potassium,sweet corn and Liaoyu18 could use Potassium with high efficiency and it belongs to a variety which could use Potassium in higher efficiency and could tolerate low Potassium.When using Potassic fertilizer,Denghai9 had the highest absorbing and its increasing yield was higher and the utilization rate of Potassic fertilizer is higher too.According to this study,it showed though there was difference between different genotypes maize about us-ing Potassium efficiency,There was no remarkable change about absorbing Natrium efficiency.Whether high Potassi-um or lowPotassium,there was no remarkable change about absorbing Natrium efficiency.This showed maize varieties which had high ability to absorb Potassium and then could tolerate low Potassium didnt’ exist Natrium and Potassium vicarism.
