摘要
以有利于推进嫩江县农业生产节本增效,有利于促进耕地质量建设,发展可持续农业,促进粮食稳产高产,增加农民收入为目标,于2009年结合农业部实施的测土配方施肥项目对嫩江县耕地地力进行调查与评价,主要表现为:有机质含量下降,氮、钾等养分也相应减少,土壤肥力逐年减退;土壤水蚀、风蚀严重。人们在生产经营中注重用地,不注重养地,用地养地失调,广种薄收,掠夺地力的不合理耕作模式,是土壤肥力减退,土壤生产能力降低的主要原因。因此,要建立优良的农田生态环境,采取多种措施增加土壤肥力,提高耕地质量。
In order to save the cost and increase the benifit of agricultural production in Nenjiang county,stimulate the construction of land,develop the sustainable agriculture,make the production of crop increasing and stable,increase the income of farmers,the farmland fertility of Nenjiang county was investigated and evaluated combining with the fertilization project of Ministry of Agriculture in 2009.The results showed that:the organic matter content and nutrients of nitrogen and potassium were decline,the fertility decreased year by year,soil erosion by water and wind was seriously.The reasons causing the decline of soil fertility and soil production capacity were as follows:farmers attached importance to use land only but not to protect land,imbalance of utilization and culture of the land,irrational cultivation mode of extensive cultivation and plunder the fertility.So we should construct good agricultural ecological environment,adopt many measures to increase soil fertility and improve the quality of cultivated field.
