The Soil Fertility Status And Measures Of Agriculture, Forestry And Grass In Jiaocheng

This experiment studied the Jiaocheng country land use status, and analyzed of the soil nutrient condition about Jiaocheng country agriculture, forestry and grass,in turn, understand the problems existing in the soil of the county. The experimental results showed that:1. In different land use types of Jiaocheng country, the forest area is the most, followed the grass, and agricultural land to a minimum. From all the villages and towns of Jiaocheng country of agriculture, forestry, grass industry use area, grass of artificial grassland and natural grassland utilization in less, not even; Agricultural land in dry land is more than the area of irrigated land, agricultural land and facilities are relatively less; And forest land area is relatively more.2. Jioacheng country make the agriculture, forestry, grassland soil pH value above in 7.70, are alkaline, even strong alkaline. In addition to the grass in natural grassland soil pH alkaline, other types of farming, forestry and grass land soil pH has a strong alkaline, especially in the agricultural land irrigated land and the dry land in strong alkaline.3. Land for farming, forestry and grass industry in various types of soil extremely lack of effective phosphorus, slowly available potassium content on the high side, rapidly-available potassium content is rich. Agricultural land in the facilities of agricultural land, irrigated soil organic and nitrogen are relatively rich, dry land soil organic matter content is moderate, total nitrogen content is below average. Woodland of each land use type in the soil organic and nitrogen content is relatively rich; in natural grassland of soil organic matter and nitrogen content is rich, artificial grassland and other grassland soil organic matter and total nitrogen content were moderate levels.4. Each land use type soil of agricultural land, forest land and grassland effective iron content in the moderate level. The soil effective copper content is relatively and effective iron content is rich, agricultural land in the facility farmland and irrigated soil effective sulfur content on the high side, other available soil sulfur content more rich.To solve above city county soil problems, proposed the use of chemical fertilizer and organic fertilizer rates, and matching dry sump water, put straw returning to grass use again, balanced fertilization, planting green manure and use other techniques, to change the soil fertility.
