摘  要：
通过田间小区试验,研究了几种施肥结构对辣椒和茄子产量及对氮、磷、钾养分吸收的影响。结果表明:(1)在供试土壤条件下,茄子和辣椒的地力产量相差不大,但茄子的施肥效应远远大于辣椒。不同施肥处理相比,无论茄子还是辣椒,有机无机肥配施及施用蔬菜专用配方肥均可显著提高蔬菜产量,其产量明显高于当地习惯施肥和NPK处理。(2)与NPK处理相比,有机无机肥配施可明显提高茄子和辣椒的氮、磷、钾吸收量和对氮、磷、钾肥的当季利用率。当地习惯施肥处理的氮、磷肥施用量明显高于茄子和辣椒的需要量,而施钾量明显偏低,因而其对氮、磷肥的利用率明显低于平衡施肥处理。(3)茄子对菜地土壤养分的利用能力低于辣椒,而对氮、磷、钾养分的需求量却大于辣椒。因此,在同样土壤肥力条件下,茄子的施肥量应大于辣椒的施肥量。(4)在供试土壤条件下,茄子和辣椒的N、P2O5、K2O施用量分别为188.94、100.16、212.46 kg/hm2和132.37、59.55、133.77 kg/hm2,茄子和辣椒所施肥料的N∶P2O5∶K2O值分别为1∶0.53∶1.12和1∶0.45∶1.01。据此,可以制定供试土壤条件下茄子和辣椒的平衡施肥量和研制其专用配方肥。

摘  要：
To understand the effect of different fertilization structure on summer pepper and eggplant yield and nutrients uptake, the field plot experiment was carried out in Vegetables base of Junshan District of Yueyang city, Hunan Province. The results showed that:( 1) The combined application of organic fertilizers and chemical fertilizers may significantly increase the yield of pepper and eggplant compared with NPK(pure chemical fertilizer) treatment and the local custom fertilization.(2) N, P and K nutrient uptake and nutrient recovery rate of the combined application of organic fertilizers and chemical fertilizers are higher than that of the local custom fertilization treatment and the pure chemical fertilizer treatment.( 3) the utilization of eggplant for soil nutrients is less than that of pepper while the requirement of eggplant for nutrient is lager than that of pepper.(4) Under the tested soil conditions, fertilizer amount of N, P2O5, K2 O for eggplant and pepper were 188.94, 100.16, 212.46 kg/hm2 and 132.37, 59.55, 133.77 kg/hm2, respectively. And the corresponding fertilizer ratios were 1:0.53:1.12 and 1:0.45:1.01, respectively. Therefore, the fertilization rate of eggplant should be larger than that of pepper at the same soil condition. According to the principle of balanced fertilization, the optimized fertilization rate for pepper and eggplant was calculated.
