Abstract:
Taking processing tomato as test material，the project in processing tomato nutrient uptake and growth in seedling stage were studied using hole tray seedling cultivation，adopt the method of light cultivation，eight kinds of different humic acid fertilizers application fertilizer formula were applied，the seedling biomass，nitrogen，phosphorus，potassium content of processed tomatoes and soil organic matter and available nutrients were determined.The roots tomatoes were scanned.The results showed that the formula for N-P-K：7-18-13，humic acid 8%，organic matter 2% of humic acid compound fertilizer（K2SO4) and formula for N-P-K：9-23-7，humic acid 8%，organic matter 2% of humic acid compound fertilizer (KCl) formula promoted root of processing tomato plant in the seedling stage and the accumulation of nitrogen，phosphorus and potassium；significantly increased the root length and specific surface area of root；improved soil organic matter and available nitrogen，available phosphorus and available potassium content，reduced the difference between the fertilizer.
