腐植酸复混肥对新疆温室苗期加工番茄养分吸收和生长的影响

Study on Effect of Applied Humic Acid Compound Fertilizer on Nutrient Absorption and Growth of Greenhouse Seedling Processing Tomatoes in Xinjiang

以加工番茄为试材,采用穴盘育苗栽培,利用光照栽培的方法,底肥施用8种不同腐植酸复混肥配方,测定了苗期加工番茄的生物量、氮、磷、钾的含量及土壤有机质和速效养分含量,并进行根扫描。结果表明:配方为N-P-K:7-18-13,腐植酸8%,有机质2%的腐植酸复混肥(硫酸钾)和配方为N-P-K:9-23-7,腐植酸8%,有机质2%的腐植酸复混肥(氯化钾)的配方促进了苗期加工番茄植株和根氮、磷、钾的积累;显著增加了根长和根比表面积;提高了土壤中有机质和速效氮、速效磷、速效钾的含量,减少了肥料用量间的差异。

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 humie acid compound fertilizer（K2 SO4 ）and formula for N-P-K：9-23-7,humie acid 8%, organic matter 2% of humic acid compound fertilizer （KCL） formula promoted root of processing tomato plant in the seedling stage and the aceumulation of nitrogen,phosphorus and potassium;signifieantly 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.
