本文探讨了博罗县下村农场土壤养分含量概况,为今后长期试验研究提供基本理论依据。分析结果表明:下村场土镶有机质含量低,土壤酸性强,不利于土壤肥力的发挥,土壤全量养分N、P、K含量不平衡,速效养分虽然有些较高以至很丰富,但其含量范围大,有相当部分土壤仍很低,所以其供应水平亦很不平衡。而坡地赤红壤则全氮低,全磷不高,全钾则高低差异很大.至于果园土壤(即耕地),养分含量亦很不一致,相差极为悬殊,没有一定的规律性.土壤养分的高低水平,对作物的养分供应起很大的作用。由于下村场土壤养分的不均衡性,在生产管理上,应因地制宜,协调养分含量,以提高施肥效果。根据下村场土壤养分含量的特点,应增施有机肥,改良土壤,并适施石灰以改善土壤酸性,以利于作物的正常生长.
This paper discussed the soil nutrient content of Xiaocun farm in Boluo County, which provided the basic theoretical basis for the long-term experimental research in the future. The results showed that the content of soil organic matter in the lower village soil was low and soil acidity was strong, which was unfavorable to the soil fertility. The content of N, P and K in total soil nutrients was unbalanced. Although the available nutrients were higher and more abundant, , A considerable part of the soil is still very low, so its supply level is also very unbalanced. The slope of red soil is low total nitrogen, total phosphorus is not high, total potassium is highly different. As for orchard soil (ie, arable land), nutrient content is also very inconsistent, the difference is extremely disproportionate, there is no certain regularity. The level of soil nutrients, the nutrient supply of crops play a big role. Due to the imbalance of soil nutrients in the lower village farms, production management should be based on local conditions, to coordinate the nutrient content in order to improve the fertilization effect. According to the characteristics of the soil nutrient content of the lower village farms, organic fertilizer should be added to improve the soil and apply lime to improve soil acidity, in order to facilitate the normal growth of crops.
