Abstract:

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.
