Effects of Physiological and Biochemica of Okra under Different Irrigations and Potassium
Using okra as the research object,a pot experiment was conducted to reveal the effect on physiolog-ical and biochemical indicators of okra,with wet irrigation,tray only irrigation,Israel's new generation irriga-tion,and traditional irrigation methods.The results showed that irrigation methods and potassium fertilizer concentrations had a significant impact on the chlorophyll content of okra plant leaves.Under wet irrigation conditions,the chlorophyll content in the leaves of okra plants was relatively high,with a maximum value of 22.55 mg/g,which was less affected by potassium fertilizer concentration.Under the same potassium fertilizer concentration,the vitality of plant root system showed as follows wetting irrigation ≈ only the diaphragm>traditional cultivation ≈ Israel's new generation irrigation.The activity of nitrate reductase in the leaves of okra plants was affected by potassium fertilizer,the concentration had a relatively small impact,with wetting irrigation ≈ only on the diaphragm>Israel's new generation irrigation>traditional cultivation,and Israel's new generation irrigation was significantly higher than traditional irrigation.
