摘  要:
按照初步制定的武汉市蔡甸区莲藕土壤主要养分丰缺指标及肥料养分施用指标进行配方施肥。结果表明,相比习惯施肥,该配方施肥肥料利用率平均提高了8.7个百分点,增施每千克N、P、K总养分的莲藕增产量(农学效率)达15.0kg,每公顷平均增产11.3%,产投比平均达9.2∶1.0,每公顷平均新增纯收入5554.5元。

摘  要:
The effects of formula fertilization based on the nutrient abundance and deficiency indicators of lotus root soil and fertilizer nutrient application of indicators were tested. The results showed that formula fertilization method had a better rationality and accuracy. Compared to custom fertilization method, its average rate of fertilizer utilixation ratio was increased by 7.6%, lotus root yield of the total NPK nutrients per kilogram (agronomic efficiency) was increased up to 15.0kg, the average yield was increased by 11.3%, the rate of production to investment was 9.2∶1.0, net income was increased by 5 554.5 Yuan per hm2.
