- Abstract:
- To screen out the optimum formula of wolfberry fertilization under integrated water and fertilizer fertigation,in this study,3yearold ‘Ningqi No.7’ was taken as the test material and six fertilization treatments were designed according to different ratios of organic matter,nitrogen,phosphorus and potassium.Compared with CK,traditional fertilization pattern of soilcovered hole was applied for A1 to A6 treatments.The integrated water and fertilizer intelligent control equipment was used for precision fertilizer recommendation management.A1 and A2 treatment were under fertilizer treatment with N,P and K,and A3,A4,A5 and A6 treatment were under treatment with organic matter+N,P and K.The field experiment was carried out in Zhongning county,the main wolfberry production area in Ningxia,to study the influences of various treatments on wolfberry production and quality.The results showed that compared with CK,the average increase rates of wolfberry production,100grain mass,content of total sugar,polysaccharide content,protein content under treatments of A1 to A6 were 18.75%,2.13%,2.16%,1.11% and 4.36%,respectively.The average grain size was reduced by 7.33 grains·(50g)-1,and the fat was reduced by 0.06 g·(100g)-1 on average.Obviously,the integrated technology of water and fertilizer could improve the wolfberry quality and production.By the comparisons of various indexes under the treatments with N,P and K and organic matter+N,P and K,it could be found that the latter had better effects.A5 treatment had the highest rate of increase in wolfberry production,100garin mass,content of total sugar and polysaccharide content,that was 39.58%,24.12%,4.75% and 2.85%,respectively.The comprehensive analyses showed that A5 treatment under the treatment of integration of water and fertilizer was the optimum fertilization.
