Effect Of Increasing Potassium Nutrition Or Spray Hormone On Growth And Physiology Characerristics Of Cotton On Liquid Foster

In this paper,takeXIN LU ZAO 13# and ZHONG MIAN 36# for example to study growth and development,as well as physiological in the light density and heavy potassium ,by monitoring grown states of cottons which cultivate by liquid foster. In the heavy density, the effect physiological characteristic on XIN LU ZAO 13# andZHONG MIAN 36# by spraying nine kinds of different density hormone ,in the seedling stage and the bud times.At the same time,it is necessary to study XIN LU ZAO 6#,XIN HAI 16#,XIN LU ZHONG 15#,which they are in the heavy potassium,and SHI K 7#,XIN LU ZAO 10#,which are in low states potassium, in lack ,in light,and heavey potassium ,which are experiments growth and the physiologicalcharacteristic's response,in the seedling and bud times.we find :1,In the heavy states potassium ,It is remarkable promoter XIN LU ZAO 13# and ZHONG MIAN 36# growth and the physiological characteristics, and ZHONG MIAN 36# physiology characteristics absorption more potassium thanXIN LU ZAO 13#. In the light potassium processing, XIN LU ZAO 13# total areas are greater than ZHONG MIAN36#.2,In the heavy states potassium①it can promote XIN LU ZAO 13# and ZHONG MIAN 36# plant high ,when spray hormone IAA-0ug/L, GA3-50ug/L, Z-0ug/L.②it can promote XIN LU ZAO13# seedling stage chlorophyll content when spary hormone ,GA3-50ug/L, IAA-80ug/L, Z-50ug/L.③it is to be abLe obviously to urge ZHONG MIAN 36# root areas enhancement,when spary hormone ,GA3-50ug/L, IAA-40ug/L, Z-50ug/L④when hormone GA3-0ug/L, IAA-40ug/L, Z-0ug/L to be possible to enhance XIN LU ZAO 13 stems, leaves potassium accumulation quantities.⑤GA3 and Z the hormone's influence are quite greater to cotton's leaf, but IAA to cotton plant's root, the stem, the leaf has the promoter action. 3,①XIN LU ZAO 6#, XIN HAI16# and XIN LU ZHONG 15# in the absorption more potassium than absorption in SHI K7#,XIN LU ZAO 10# light potassium②The potassium is high state and not onLy the potassium light efficiency's chLorophyll synthesis is very high in heavy potassium the content, but in the light potassium's content.③The seedling stage, the cotton in the highy potassium , root system surface area, the root system vigor must be higher than the potassium light, and existence extremely remarkable difference④potassium accumulation quantities, when seedling stage: in the potassium heavy cotton along with the potassium density's enhancement, nutrient content must be greater than the potassium light nutrient content, showed that it explanted the promoter action to the potassium heavy cotton.⑤The bud times, the heavy potassium in cotton and light potassium in cotton endogene hormone content in the light potassium medium and heavy density potassium, the leaf, the stem, the root content is quite small.
