摘要
通过赤峰市元宝山区2011年番茄田间试验,研究了不同施氮量对番茄养分吸收、养分分配及番茄产量的影响。结果表明,增施氮肥可以显著提高番茄的产量,番茄果实中的N、P、K含量,番茄果实与茎叶中N、P、K养分的比值,但对番茄的茎叶影响不明显。说明在当地气候和土壤条件下,应该增加氮肥的施用量提高番茄产量和养分含量。
A field trail in Yuanbaoshan District of Chifeng City to study the effect of different nitrogen application rates on the concentration and distribution of nutrients in tomato and the yield of tomato. The results showed that with the raise of N fertilizer rate,the yields of tomato and the concentration of NPK in the fruit of tomato was raising. The ratio of NPK that differentiated in the fruits of tomato and the stems and leaves of the tomato was raising with the raising of N fertilizer rate. The results also indicated that effect of different nitrogen application rates on the stems and leaves yield of tomato was not obvious. Note in the local climate and soil conditions,should increase the amount of nitrogen fertilizer to improve yield and nutrient content of tomato.
