海涂蔬菜基地由于土壤碱性强,导致钙对磷素产生固定效应,土壤速效磷含量降低,一般在10毫克/公斤(ｍｇ/ｋｇ)左右,远低于高产蔬菜土壤速效磷60毫克/公斤的水平,对蔬菜的产量质量影响较大。为解决涂园蔬菜的缺磷问题,我们于近年进行了磷肥不同用量的肥效试验,现将结果整理如下。1 Due to the strong alkalinity of the soil, the vegetable base of TURP has a fixed effect on phosphorus and the content of available phosphorus in the soil decreases, generally about 10 mg / kg (mg / kg), much lower than 60 mg / kg of available phosphorus The level of vegetable yield and quality impact. In order to solve the problem of phosphorus deficiency in painted garden vegetables, we carried out fertilizer efficiency tests on different amounts of phosphate fertilizer in recent years. The results are summarized as follows. 1
