Problems solved by technology

Since the mid-1990s, open-air burning of crop stalks and dumping of livestock and poultry manure have become serious problems facing the ecological environment in the vast rural areas of our country. This not only seriously pollutes the environment, but also greatly wastes the raw materials of organic fertilizer products, and causes A large number of nutrient resources are lost outside the soil-plant system

Embodiment 1

[0025] Embodiment 1: The preparation that is used for planting Mexican corn environmental protection matrix

[0026] Preparation process and slot molds such as figure 1 and figure 2 shown.

[0027] (1) Fresh livestock and poultry manure is collected in the livestock manure tank and stacked naturally (temperature 25-32°C, humidity 50-60%) for about 30 days. The straw straw is naturally air-dried and cut to about 2cm, and then the livestock and poultry The feces and straw fragments are stirred and mixed according to the dry weight ratio of about 7:3 to make agricultural organic waste.

[0028] (2) Lay vermiculite (particle size about 2-4mm) in a trough mold (the mold is a rectangular trough with a length of 100cm, a width of 50cm, and a height of 60cm) to make a vermiculite layer about 15cm high, and then Lay a sieve a with a pore size of 800 μm on the surface of the vermiculite layer, add the agricultural organic waste prepared in step (1) on the surface of the sieve a to f...

Embodiment 2

[0031] Embodiment 2: the recipe optimization of environment-friendly matrix

[0032] The depth of the vermiculite layer in the environmental protection matrix is ​​15cm, respectively adjust the volume ratio of the agricultural organic waste A layer and the vermiculite layer to 1~3:1, add the total amount according to the agricultural organic waste A layer as described in Example 1 Nitrogen source 3.0 mol / m 3 (in N 2 O), phosphorus source 4.5 mol / m 3 (in P 2 o 5 meter) and potassium source 1.0mol / m 3 (in K 2 (2 meter), then the agricultural organic waste A layer and the vermiculite layer in the tank mold (ie the tank type earthworm treatment reactor) are fixed and formed. The added inorganic nitrogen source is urea, the inorganic phosphorus source is calcium superphosphate, and the inorganic potassium source is potassium nitrate. At the same time, the water content of the matrix is ​​controlled to about 70% by artificial spraying.

Embodiment 3

[0033] Embodiment 3: environmental protection matrix is ​​used for the plantation of Mexican corn

[0034] According to the method of embodiment 1, the environment-friendly matrix for planting Mexican corn is prepared, and the operation and parameters of each material are the same as in example 1, except that the environment-friendly matrix samples are divided into 3 groups, and the vermiculite layer and agricultural organic waste in group 1 The volume ratio of layer A is 1:1, urea 11g, superphosphate 49g, potassium nitrate 15g; the volume ratio of vermiculite layer and agricultural organic waste A layer in group 2 is 1:2, urea 22g, superphosphate 98g, Potassium nitrate 30g; the volume ratio of the vermiculite layer and the agricultural organic waste A layer in group 3 is 1:3, urea 32g, superphosphate 250g, potassium nitrate 44g; at the same time, the soil is used as a control, and the soil is planted on the environmental protection substrate and the control respectively For M...

Abstract

The invention discloses an agricultural organic waste for the planting of zea mexicana and a preparation method and application thereof. The method for preparing the agricultural organic waste comprises the following steps of: adding vermiculite into a tank body die to prepare a vermiculite layer; putting an animal manure mixture (a) on the surface of a screen (a) to prepare an animal manure mixture layer A, and performing pre-fermentation; inoculating earthworms on the animal manure mixture layer A, and standing at the temperature of between 10 and 20 DEG C under the conditions of sunshading and the humidity of 60 to 75 percent for 25 to 45 days; and taking the animal manure mixture layer A out, performing pile turning, removing the earthworms, and adding a nitrogen source, a phosphorus source and a potassium source to obtain the agricultural organic waste for the planting of the zea mexicana. According to the agricultural organic waste, raw materials are renewable resources, so that environmental damage is avoided; and the earthworm treatment of the agricultural organic waste and the production of an environment-friendly matrix are integrated into the same tank type earthworm reactor, the reactor and the matrix which is regulated by a formula can be used for pasture planting directly, and obtained pastures can be circulated in the production process of animal husbandry again.

Description

(1) Technical field [0001] The invention relates to the treatment and resource utilization of agricultural organic waste, in particular to an environment-friendly substrate for planting Mexican corn and a manufacturing method thereof. (2) Background technology [0002] There are many types of agricultural organic waste, mainly livestock manure and crop straw. my country's agricultural waste presents four major characteristics, that is, large quantity, poor quality, low price, and more harmful pollution characteristics. According to reports, the total annual output of various crop straws in my country is more than 700 million tons, including 230 million tons of rice straw, 220 million tons of corn straw, 100 million tons of beans and autumn miscellaneous grains straw; sawdust, wood shavings and other forestry waste 1.6×1010Kg; my country’s annual livestock manure discharge is about 2.04 billion tons, and its total storage of nitrogen, phosphorus, and potassium is about 0.633×...
