Embodiment Construction
[0018] The deep soil taken from Hefei Rail Transit Line 1 was exposed to the sun for seven days (except for cloudy and rainy days), and then rolled, crushed, and sieved to obtain a deep soil matrix with certain air permeability and water permeability.
[0019] 1. Take 800kg of deep soil substrate, 140kg of urea, 40kg of superphosphate, 18kg of potassium sulfate, and 2kg of rooting powder, stir well and mix well.
[0020] 2. Take 750kg of deep soil substrate, 178kg of urea, 50kg of superphosphate, 20kg of potassium sulfate, and 2kg of rooting powder, stir well and mix well.
[0021] 3. Take 850kg of deep soil substrate, 108kg of urea, 30kg of superphosphate, 10kg of potassium sulfate, and 2kg of rooting powder, stir well and mix well.
[0022] 4, in example 1,2,3 also can add 50-100kg plant ash.

The invention discloses composite nutrient soil. The composite nutrient soil comprises, by weight, 75 % to 85 % of a deep soil substrate, 10 % to 20 % of urea, 2 % to 8 % of calcium superphosphate, 1 % to 3 % of potassium sulfate, 0.1 % to 0.3 % of rooting powder and 10 % to 50 % of plant ash. Deep soil is the soil taken out from at least 10 meters below the ground, the deep soil is exposed to sunlight for 5 to 10 days and is grinded, broken stones are smashed and sieved and then the deep soil substrate is obtained; the composite nutrient soil can be applied to a nutritional bowl, and can also cover a low-yielding farmland, or new soil replacement can be carried out on a farmland by using the composite nutrient soil. The composite nutrient soil can carry out a field contrast test on tomatoes, peppers, cucumbers and eggplants through a covering method, and increase production is generally more than 20 percent.
Description
1. Technical field [0001] The invention relates to a soil for planting crops, specifically a compound nutrient soil with deep soil as the main component. The deep soil refers to the soil taken out from the surface at least 10 meters below. 2. Background technology [0002] At present, in addition to the severe shortage of cultivated land resources in my country (per capita cultivated land is only 1.46 mu, less than half of the world average), the following problems are also faced. Major infrastructure construction, along with the strengthening of ecological environment construction, the state plans to return 220 million mu of farmland by 2010, and the momentum of reduction in the number of cultivated land in the country is irreversible. Second, the quality of the soil has been seriously degraded. Over the years, due to heavy use and light cultivation, the soil has been degraded, the cultivated layer has become shallower, the tillability has deteriorated, water conservation a...
