花生是合浦县主要经济作物之一,常年种植面积在20万亩上下。近几年,花生施肥水平有较大的提高,但很多农民为了方便起见,少施甚至不施有机肥,在化肥施用上,无论是高产田、中产田或低产田都搞平均施用,结果经济效益不高。为了探索花生经济合理施肥的有效途径,我们于1984～86年进行了花生产量与土壤肥力的相依关系及对当年施肥的依赖程度作了试验研究,现将结果报告如下。 Peanut is one of the main cash crops in Hepu County. Its perennial planting area is about 200,000 mu. In recent years, peanut fertilization levels have greatly improved, but for the sake of convenience, many farmers do not apply or even apply organic fertilizer, fertilizer application, whether it is high yield field, middle field or low yield fields are engaged in the average application, the results of the economy Benefit is not high. In order to explore the economic and rational fertilization of peanuts an effective way, we carried out in 1984 to 86 the relationship between peanut yield and soil fertility and dependence on the degree of fertilizer made the pilot study, the results are reported as follows.
