Study On The Screening Of Compound Matrix Formula Of Tomato

In this study, fermented cassava dregs are as primary’ material, mixed with different proportion of mature vinegar residue and vermiculite. And compound matrix suitable for tomato, cherry tomato seedling was selected. Based on the optimum substrate, Application technology of nitrogen phosphorus potassium on tomato and cherry tomato seedlings is studied. The results are as follows:1、Analysis of physical properties of matrix material, and the cassava residue as raw materials were studied through germination rate, seedling selection of complex determination of seed. The results showed that germination effect L1 (The cassava dregs: vinegar residue:vermiculite= 4:1:3) is the best.2、The seedling germination rate, emergence rate, morphological index, whole plant dry matter content, seedling index analysis of tomato, cherry tomato seedling in 5 kinds of mixed substrates in the performance, seedlings after transplanting, analysis of tomato, cherry tomato fruit growth index and fruit index. The tomato, cherry tomato seedling in compound L1 (The cassava dregs:vinegar residue:vermiculite= 4:1:3) is the best.3、The optimum compound matrix based on the addition of different nitrogen, phosphorus and potassium content, analysis of tomato, cherry tomato seedling morphological indicators, whole plant dry matter content, seedling index, and the seedling planting, growth index analysis of tomato, cherry tomato. The plant of tomato seedlings to N 0.030g, P2O50.060g, K2O 0.075g (N:P2O5:K2O=1:1.9:2), growth index of seedling growth indexes and after planting were the best, individual plant of cherry tomato seedlings to N 0.030g, P2O5 0.060g, K2O 0.075g (N:P2O5:K2O=1:1.9:2), growth index of seedling growth indexes and after planting w;ere the best.
