Problems solved by technology

[0003] The purpose of the present invention is to solve the activation method of using compound fertilizer or increasing farmyard manure, so that 70% of the phosphate fertilizer used every year is fixed by the soil, which increases the workload and input cost, and the nutrient utilization rate is low in the crop growth process. The problem of agricultural non-point source pollution provides a method for activating soil nutrients in slope farmland

specific Embodiment approach 1

[0008] Specific embodiment one: the method for activating soil nutrients in slope cultivated soil layer in this embodiment is as follows: Step 1, prepare phosphorus-solubilizing bacterial fertilizer: inoculate phosphorus bacteria cells on the grass carbon, make the phosphorus-solubilizing bacteria in every gram of phosphorus-dissolving bacterial fertilizer Cell number 10 11 1; step 2, during spring sowing, apply phosphate-dissolving bacterial fertilizer, crop rhizosphere fertilizer and chemical fertilizer together according to the application amount of 1kg phosphate-dissolving bacterial fertilizer, 4kg crop rhizosphere fertilizer, and 10kg compound fertilizer per mu; step 3, Before the onset of the rainy season in early July, after the last trip to the field, cover the surface of the sloping farmland with straw until harvesting in autumn, and then plow the straw into the soil with a tractor after the autumn harvest.

[0009] The crop rhizosphere fertilizer described in step 2 ...

specific Embodiment approach 2

[0011] Embodiment 2: This embodiment differs from Embodiment 1 in that the phosphate-solubilizing bacteria in step 1 is Bacillus megaterium. Others are the same as the first embodiment.

specific Embodiment approach 3

[0012] Specific embodiment three: the process of planting crops in the present embodiment is as follows: one, when sowing in the spring of the first year, apply soybean special-purpose fertilizer 17kg per mu, then take two shovels and three times of management mode, carry out rotary tillage after autumn harvest, average per acre after autumn harvest The yield per mu of soybeans is 160kg; 2. In the spring of the second year, plant corn on the original ridge of the previous soybean crop, apply 30kg of compound fertilizer per mu, and adopt the management method of two shovels and three trips. After the autumn harvest, the average yield of corn per mu is 700kg .

Abstract

The invention provides a method for activating nutrients of a soil plough layer of a slope farmland, which relates to a method for activating nutrients of soil. The invention solves the problems that the workload and the investment cost are increased due to the condition that 70 percent of phosphatic fertilizer applied to every year is cured by the soil by using the method for activating soil by applying a compound fertilizer or additionally applying a farm manure and the area pollution in agriculture is increased due to lower nutrition utilization rate during the growth of crops. The method comprises the steps of: applying a phosphorus-solubilizing bacterial manure, a crop root fertilizer and a fertilizer together when planting crops in spring; before the rains come at the beginning of the July, covering straws on the surface of the slope farmland until the crops are harvested in autumn after the last time of turning the soil and digging weeds; and after the crops are harvested in autumn, turning over the straws into the soil by using a tractor. Compared with the conventional planting method, the fertilizer utilization rate is increased by above 10 percent, the yield is increasedby above 10 percent, the soil erosion modulus is reduced, and the scientific significance is obtained.

Description

technical field [0001] The invention relates to a method for activating soil nutrients. Background technique [0002] At present, in the process of agricultural production on sloping farmland, the nutrient management technology is relatively backward. The traditional method is to increase production by applying a large amount of chemical fertilizers or farmyard manure to the planting site of sloping farmland. However, in the process of agricultural production, with With the development of modern science and technology, there is less and less farmyard manure available for agricultural production, so that only a few farmers use farmyard manure every year to fertilize the soil, and they can only use a large amount of chemical fertilizers every year to increase food production and increase production. The cost increases the workload, and a large amount of chemical fertilizer is invested every year, which increases agricultural non-point source pollution and cannot meet the low-c...
