Abstract
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
One, technical field
The present invention relates to a kind of soil for kind of plant, is exactly a kind of compound nutritional soil taking deep soil as main component.Described deep soil refers at least 10 meters of following soil that take out from earth's surface.
Two, background technology
China's cultivated land resource (only 1.46 mu of per capita cultivated lands except critical shortage at present, the half of not enough world average level), also face following problem, one, the whole nation is because of conceding the land to forestry, economic and technological development zone and town development, and the great infrastructure construction such as traffic, the energy, follows the reinforcement of improvement of the ecological environment, state plan to 2010 year is conceded the land 2.2 hundred million mu, and the impetus that national quantity of cultivated land reduces is irreversible.Its two, soil quality serious degradation, for many years due to Farmland was overused without proper attention to the maintenance of its fertility, cause that Soil degradation, topsoil shoal, tilth variation, preserve moisture and fertility and anti-disaster ability reduce, in China, low fertility cultivated area accounts for 2/3 left and right at present, and soil organic matter content is on the low side, and nutritional deficiency area increases day by day.Have 56% area severe potassium deficiency, in arable soil approximately over half, trace element is deficient, and the shortage area of boron, manganese, zinc, iron amounts up to 23.6 hundred million mu (inferior).Its three, pollution grows worse, the whole nation has 1.5 hundred million mu of arable lands to be subject to pollution in various degree.The malicious rice event particularly occurring is in the recent period the alarm bell that people have beaten heavy metal contamination.
For solving the problem of Soil degradation, the national Ministry of Agriculture has issued " planning of fertile soil Engineering Project Construction ".But the improvement of soil quality takes time and efforts, and to containing green, non-harmful food requirement cry day, so Nutrition Soil just arises at the historic moment.Current Nutrition Soil is mainly taking humus or free of contamination ecosystem veneer of soil as substrate preparation.
Current advancing in Chinese Urbanization, industrialization, modern process, the appearance of deep soil is not only to environment, ecology, and national economy and social development has been brought to serious threat.To build 200km subway as example, need to take out 7,200 ten thousand side's deep soil (high 12m, wide 30m), though according to modern extruding type excavate also have 50 percent 3,600 ten thousand sides' deep soil must take out, transport, stacking or landfill, country will pay huge expenditure for this reason.Deep soil deposits extruding through for many years, soil property unity structure is poor, permeability extreme difference, and biological activity is low, and sowing is not germinateed, and plants seedling and does not survive, even if also No kernels or seeds are gathered, as in a year of scarcity in minority survival, must can plant plant through several years slaking.Have experiment to show, even if adopt modern advanced immature soil into cultivated land, Study on Fertilizing technology, the every triennium of the soil organism just improves 5-8g/kg.Visible culture fertility is a very long process, not by accomplishing once, effort in 2 years.Someone uses the method for breeding earthworm with accelerating maturing, but so a large amount of earthworms source cannot solve.
Three, summary of the invention
The present invention is directed to the environment and ecology problem that deep soils a large amount of in urban construction faces, be intended to deep soil and find an outlet.
Applicant's experiment shows, deep soil just becomes loose after the solar radiation (different different because of season) of 5-10 days, and adds water into mud, no longer hardens after solid, and its ventilation property, water permeability are greatly improved.
The present invention is processed into compound nutritional soil according to this characteristic of deep soil just.
This compound nutritional mount is drawn together each component of following mass percent:
Preferred:
In above-mentioned compound nutritional soil, also can add the plant ash of total mass 5-10%.
Described root-inducing powder is a kind of broad-spectrum germicide.
Described deep soil matrix refer to deep soil after 5-10 day solar radiation, roll again, broken, cross and screen out the soil that rubble obtains.
This compound nutritional Tu Song Anhui Province academy of agricultural sciences's clay fertilizer detects (report number AHKW-0003-2013) result: pH6.7, available phosphorus 14.41mg/kg, alkali-hydrolyzable nitrogen 60.72mg/kg, available potassium 67.43mg/kg, organic 6.79g/kg, water content 15.37 ‰.Meet the standard regulations such as NY/T1121.2-2006, LY/T1233-1999, NY/T889-2004.
This compound nutritional soil can be used for nutrition bowl, also can be used for big area farmland cover, in, on low yield farmland, cover thick compound nutritional soil, also can replace for soil moved in to improve the original.
This compound nutritional soil adopts cladding process to carry out field comparison test to tomato, capsicum, cucumber, eggplant through Tian Bie mountain, Hefei City sprout vegetable institute, generally increases production more than 20%, and tomato, capsicum are increased production up to 30%.Particularly, to being subject to the farmland of the slight pollutions such as agricultural chemicals, after covering certain thickness (exceeding the root system degree of depth), still can produce green non-pollution vegetables.
Four, embodiment
Get the deep soil that track traffic line in Hefei City's takes out, through Exposure to Sunlight (except overcast and rainy) in seven days, then roll, broken, sieve, obtain having the deep soil matrix of certain air permeability and water permeability.
1, get deep soil matrix 800kg, urea 140kg, calcium superphosphate 40kg, potassium sulfate 18kg, root-inducing powder 2kg, fully stirs, mixes.
2, get deep soil matrix 750kg, urea 178kg, calcium superphosphate 50kg, potassium sulfate 20kg, root-inducing powder 2kg, fully stirs, mixes.
3, get deep soil matrix 850kg, urea 108kg, calcium superphosphate 30kg, potassium sulfate 10kg, root-inducing powder 2kg, fully stirs, mixes.
4, in example 1,2,3, also can add 50-100kg plant ash.
Claims (3)
1. a compound nutritional soil, is characterized in that comprising each component of following mass percent:
Described deep soil refers at least 10 meters of following soil that take out from earth's surface; Described deep soil matrix refer to deep soil through within 5th~10, rolling again after solar radiation, broken, cross and screen out the soil that rubble obtains.
2. Nutrition Soil according to claim 1, is characterized in that:
3. Nutrition Soil according to claim 1 and 2, is characterized in that: in Nutrition Soil, also contain plant ash, the 5-10% that add-on is total mass.
