In 2020, three cities have agricultural lands 165296.46 hectares, but the cultivated lands only have 16133.73 hectares, account for 9.76% of the total agricultural land area, 8.39% of the total national area of the whole city, and the average cultivated land area is only 240 square meters, which accounts for 26.61% of the average domestic cultivated land area (910 square meters) of the same year.
Comparing and analyzing the change data of the farmland in 2010-2020, and displaying the result: in 2009-2019, the whole cultivated land area in the whole market shows a trend of reduction, but the reduction is not large, and the annual average growth rate is-0.21%. The water irrigated land area is reduced from 5.43 hectares in 2009 to 2.16 hectares in 2019 at a rate of-8.81% by adjusting the water field area and the water irrigated land area to a speed of 0.34% in year. The area of the dry land fluctuates for 10 years, but the overall situation of small increase is shown, and the annual average increase rate is 0.06%.
The table above shows how the landscape pattern of the cultivated land changes in the three-city in the last 10 years.
The comparative analysis of the evaluation results of the other areas such as the three-city farmland in 2015-2018 shows that: by the end of 2018, the area of investigation and assessment of the quality of the three-city cultivated land and the like is 23235.995 hectares, and the three-city cultivated land comprises cultivated lands of 4 and 13 and cultivated lands of 10 grades according to the rules of agricultural land quality classification and the like (GB/T28407-2018). By adopting an area weighting method, the average quality of the three-city cultivated soil is calculated to be 7.33 and the like, the cultivated soil quality grade is generally low, and the quality is poor. Only 1238.49 hectares (1-4 etc.) are available in the whole city, most of the cultivated lands are concentrated on three levels of 5 etc., 6 etc. and 12 etc. with areas of 7264.04, 3841.76 and 4608.32 hectares respectively. Meanwhile, the total area of the cultivated lands (11-15, etc.) with relatively poor quality is 4,617.48 hectares, and the proportion is approximately 20%. The area of low yield in the whole city is overlarge, the area of high yield field is insufficient, and the integral quality of the cultivated land in the city is not high.
According to the national second soil census nutrient grading standard, the three-city soil presents the characteristic of high phosphorus and potassium deficiency, the average effective phosphorus content of the soil in 2019 is 97.99 mg/kg, which is far higher than the critical value of the first-level standard, the quick-acting potassium content is lower, only 4.7 mg/kg, the soil belongs to the sixth-level, and the organic matter content (15.62 g/kg) also belongs to the medium lower level. Compared with 2013, the method has the advantages that the effective phosphorus content of the soil is improved, the soil per kilogram is increased by 58.86 mg, the organic matter content of the soil per kilogram is reduced by 4.13 mg, and the quick-acting potassium content per kilogram is reduced by 1.11 mg, so that the conditions of a certain degree of nutrient imbalance, unreasonable nitrogen, phosphorus and potassium nutrient proportion of the soil, weak acid of the soil, reduced comprehensive production capacity of the soil and the like exist in all-market cultivated lands, negative influences are formed on crop growth, and certain threat is presented to grain safety.
The above table shows the quality of the three-city cultivation in 2015-2019.
