摘  要:
在日光温室内,以番茄品种卡鲁索(Caruso)为试材,进行长季节栽培,研究植株对氮、磷、钾的吸收特性。结果表明:在本试验条件下,番茄在不同时期对氮、磷、钾的吸收比例不同,全生育期内N:P_2O_5;K_2O=1:0.220~0.545:2.079~3.312,氮、磷、钾的吸收量呈单峰曲线,采收中期达最大值,营养吸收高峰期在采收中期,营养敏感期在坐果期至采收中期。每生产 100kg番茄产品需吸收N 0.19~ 1.03kg, P_2O_5 0.06~ 0.16kg, K_2O 0.58~ 3.42kg。番茄需钾最多,氮次之,磷最少。

摘  要:
The experiment was conducted using Caruso tomato variety in solar greenhouse, in order to study the absorption properties to N, P, K in long season cultivation. The results showed that the proportion of nutrient absorbed to N, P, K was different in different time of tomato, N: P_2O_5: K_2O= 1:0.220 ~ 0.545:2.079 ~ 3.312 in all the time, the content of absorption to N, P, K was a single peak curve, the maximum appeared at the middie stage of picking. The peak stage of nutrient absorbed appeared at the middle stage of picking, the sensitive stage of nutrient absorbed appeared from fruit setting to the middle stage of picking. The plant needed to absorb N 0.19 - 1.03kg, P_2O_5, 0.06 ~ 0.16kg, K_2O 0.58 ~ 3.42kg to produce 100kg tomato product. The character of nutrient absorbed of tomato was K>N>P.
