阜阳市颍东区耕地地力与粮食增产潜力分析

为了研究阜阳市颍东区耕地地力对粮食增产潜力的影响，通过利用阜阳市颍东区耕地地力评价结果，将颍东区耕地地力划分为5个等级，并对颍东区的各等地的地力状况进行分析。结果表明，颍东区一、二等地面积为16876 hm2，占全区耕地总面积的41.04%，该类地土壤养分含量水平呈中等偏上水平，地力水平较高；三至五等地地力水平较差且面积较大，共24248.2 hm2，占全区耕地面积的58.96%。研究得出，三至五等地粮食生产具有很大的增产潜力，同时，颍东区生产实践表明，一、二等地仍具有一定的增产潜力。通过实行秸秆还田、科学施肥、合理轮作以及土地流转等措施，可有效提高耕地地力，促进粮食增产，颍东区粮食生产具有很大的增产潜力。

The Analysis of the Arable Fertility and the Potential of Grain Production in Yingdong Area of Fuyang City

In order to research the influence of the arable fertility and the potential of grain production in Yingdong area of Fuyang City. This paper analyzed the fertility status of different levels of arable and divided the arable fertility into 5 levels by using the results of the evaluation of arable fertility. The results indicated that the area of level 1 and level 2 of Yingdong area was 16876 hm2 and the area proportion was 41.04%. The soil nutrient content of these levels was above the average level and arable fertility level was higher. The arable fertility level of the arable in level 3 to 5 was lower and the area was larger, a total of 24248.2 hm2, accounting for 58.96% of the all arable area in Yingdong area of Fuyang City. As a results, the grain production of level 3 to 5 have a great capacity of increasing production. At the same time, the production practice showed that level 1 and level 2 still had certain capacity for increasing production. The measures of straw returned, scientific fertilization, proper crop rotation and land circulation, which could effectively improve the arable fertility and promote the grain production, the potential for grain production was great in Yingdong area.
