Effects Of Reclaimed Drip Irrigation On Growth,Yield And Quality Of Cucumber And Eggplant

In this paper,the effect of reclaimed drip irrigation on the yield and quality of cucumber and eggplant was studied.Based on the test site of Yingli Urban and Rural Municipal Industrial Group in Shapotou District,Ningxia City,using comparative experiments and orthogonal experiments,the system was tested under the membrane.The effects of different irrigation quotas and fertilization amount on the growth mechanism,photosynthesis,yield and quality of cucumber and eggplant under drip irrigation conditions provided theoretical basis and technical support for the improvement of yield and efficiency of cucumber and eggplant in Datian.The main research results are as follows:(1)Using the comparative test method of different drip irrigation irrigation quotas of reclaimed water and tap water,the growth and development indexes(plant height,stem diameter and leaf area)and photosynthesis index(chlorophyll,net photosynthetic rate,transpiration rate,Effects of stomatal conductance and intercellular carbon dioxide concentration,yield and quality(vitamin C,soluble solids,soluble sugars and total acids).The results showed that the growth and development,photosynthesis,yield,vitamin C,soluble solids and soluble sugar of cucumbers with regenerated drip irrigation increased compared with the value of tap water cucumber,while the total acid content decreased.With the increase of irrigation quota,the growth and development index,photosynthesis index,yield,vitamin C and total acid content of cucumber increased gradually,and soluble solids and soluble sugar gradually decreased.(2)Using the comparative test method of different irrigation quotas of reclaimed water and tap water,the growth and development index,photosynthesis index,yield and quality index(vitamin C,soluble sugar,free amino acid,crude fiber and nitrate)of eggplant with different irrigation quotas were studied.Impact.The results showed that the growth and development index,photosynthesis index,yield,vitamin C,free amino acid,and nitrate content of the regenerated water-stained eggplant increased compared with the indexes of eggplant irrigated by tap water,while the soluble sugar and crude fiber decreased.With the increase of irrigation quota,the growth and development index,photosynthesis index and yield of eggplant gradually increased,and the quality indicators gradually decreased.(3)Using three-factor and three-level orthogonal test methods to study the irrigation water quality,irrigation quota and fertilization amount on eggplant growth and development index,photosynthesis index,yield and quality index(vitamin C,soluble sugar,free amino acid,crude fiber and nitric acid)The effect of salt).The study found that the factors affecting growth and development indicators,photosynthesis indicators,yield and quality,primary and secondary factors,single factor changes and optimal combination.The range analysis and variance analysis were carried out for each treatment.The order of the three factors affecting eggplant yield was:irrigation quota B>fertilization amount C>irrigation water quality A.Among them,irrigation quota and fertilization amount have a significant impact on eggplant yield,and irrigation water quality has a significant impact on eggplant yield.
