Effects Of Reclaimed Drip Irrigation On Growth,Yield And Quality Of Pepper And Tomatoes

Aiming at the effect of reclaimed drip irrigation on the yield and quality of pepper and tomato,based on the vegetable base of Zhongshui Plant in Zhongwei City,Ningxia,the effects of growth and development,yield and quality of reclaimed drip irrigation pepper and tomato were studied.It provides theoretical basis and technical support for water-saving irrigation and upgrading of vegetables.The main research results are as follows:(1)Using the comparative test method,the effects of different irrigation quotas on the growth index,yield and quality of pepper were studied.The results showed that:1 Reclaimed drip irrigation can promote the growth and yield of pepper.Recycled drip irrigation reduces the content of vitamin C,capsaicin and soluble protein in pepper,and increases the content of nitrate and soluble sugar.2 Under the same conditions of water and fertilizer,the plant height,vitamin C,capsaicin and soluble protein of the hornhorn pepper were lower than that of the horn pepper,but the stem diameter,soluble sugar,nitrate and yield were higher than that of the horn pepper.3 The irrigation quota is 4540m3/hm2.When the water quality is reclaimed water,the growth index and yield are the best,and the optimal irrigation quota is under the test conditions.(2)Using the comparative test method,the effects of different irrigation quotas on the growth index,yield and quality of tomato were studied.The results showed that:1 Reclaimed drip irrigation can promote the growth and yield of tomato.Recycled drip irrigation reduces the vitamin content of tomatoes and increases the content of total acid,soluble solids,lycopene and soluble sugar.Regeneration drip irrigation promotes photosynthesis in tomato.2 The irrigation quota is 3235m3/hm2.When the water quality is reclaimed water,the growth index and yield are the best,and the optimal irrigation quota is under the test conditions.(3)Using three-factor and three-level orthogonal design methods,the effects of different water quality,irrigation quota and fertilization amount on pepper growth index,photosynthesis,yield and quality were studied.The results showed that different factors on pepper growth index and photosynthesis The primary and secondary factors,the single factor variation law and the optimal combination of the action index value,yield and quality.The results showed that the main difference between the three factors and the variance analysis was:irrigation quota B>fertilization amount C>water quality A.The amount of irrigation,water quality and fertilizer application had significant effects on yield.For tap water,the irrigation quota is 180 m3/hm2 and the fertilization quota is 75 kg/hm2.
