Problems solved by technology

[0003] However, there are two problems in the application process of organic fertilizers: one is that the amount of application is large, which requires a lot of labor; the other is that the operation is inconvenient, which often prolongs the time of fertilization, resulting in uneven growth of crops
3. Most of the organic fertilizers are dirty and smelly, making users feel uncomfortable
[0005] Solid organic fertilizers are currently not available for drip application or pipe fertigation

Embodiment 1

[0024] Embodiment 1 farm chicken manure is drip-applied to field crops

[0025] Adopt the retting processing device shown in accompanying drawing 1. In the attached drawing 1, 1 is a composting tank, 2 is a drain pipe, 3 is a 20-mesh stainless steel filter, 4 is a primary filter, 5 is an 80-mesh stainless steel filter, 6 is a system valve a, and 7 is a secondary filter Pool, 8 is the filtrate outflow pipe, 9 is the spacer layer, 10 is the system valve b, 11 is the system valve c, 12 is the system valve d.

[0026] The retting treatment device comprises a retting tank 1, a filter tank 4 and 7, a filter screen 3 and 5, system valves 6, 10, 11 and 12; Spacer layer 9, filter screen 3 and 5 are arranged on spacer layer 9; Retting pool 1 and filter pool 4 and 7 are all provided with drainpipe, filter pool 7 and drip irrigation device (existing conventional device, not indicated in accompanying drawing 1 ) are connected through the filtrate outflow pipe 8; the drain pipe and the fi...

Embodiment 2

[0036] Embodiment 2 Farmhouse pig manure is drip-applied to field crops

[0037] Adopt the retting treatment device shown in accompanying drawing 1.

[0038] (1) Put the collected pig manure in the composting tank 1, add water to retting for 15-30 days according to the weight ratio of pig manure: water = 1:3; let it fully ferment and decompose.

[0039] The retting solution in the upper layer of the retting tank 1 first enters the primary filter pool 4 through the 20-mesh stainless steel filter screen 3 due to the natural pressure difference, and after reaching a certain liquid level, the filtrate enters the secondary filter pool 7 through the 80-mesh stainless steel filter screen 5;

[0040] (2) Open the system valve d, the filtrate flows out through the filtrate outlet pipe 8, and enters the drip irrigation system after passing through the 120-mesh screen or laminated filter at the head of the drip irrigation device (not marked in Figure 1), and reaches the crop root by the ...

Embodiment 3

[0043] Embodiment 3 Peanut bran or bean cake is applied dropwise to field crops

[0044] Adopt the retting treatment device shown in accompanying drawing 1.

[0045] (1) Put peanut bran or bean cake in the composting pool 1, add water to retting for 30 to 45 days according to the weight ratio of peanut bran: water = 1: 3 ~ 5; bean cake: water = 1: 4; let it fully ferment and decompose .

[0046] The retting solution in the upper layer of the retting tank 1 first enters the primary filter pool 4 through the 20-mesh stainless steel filter screen 3 due to the natural pressure difference, and after reaching a certain liquid level, the filtrate enters the secondary filter pool 7 through the 80-mesh stainless steel filter screen 5;

[0047] (2) Open the system valve d, the filtrate flows out through the filtrate outlet pipe 8, and enters the drip irrigation system after passing through the 120-mesh screen or laminated filter at the head of the drip irrigation device (not marked in ...

Abstract

The invention discloses a method for processing and applying organic fertilizer and a processing system. The applying method comprises the following steps: after adding water into solid organic fertilizer and retting, filtering or directly filtering liquid-state organic fertilizer to obtain organic fertilizer filtrate, carrying out drip irrigation on the organic fertilizer filtrate by an irrigation device into the root area of a crop and the like. The invention also provides a system realizing the method. By the method, the solid organic fertilizer which is commonly used in farmhouses is processed into uniform liquid-state fertilizer capable of carrying out irrigation and drip application, and the uniformity of fertilization is ensured; a traditional organic fertilizer application mode isfundamentally changed, and the invention is clean, sanitary, timesaving and laboursaving, can utilize the prior conventional irrigation device, has low running cost and low technical requirement, is simple and practical and is very suitable for popularization and application in industries applying drip-irrigation fertilization facilities, such as fruit gardens, tea gardens, economic forests, vegetables and the like, in hills and mountainous areas in China.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a novel application method of organic fertilizers including solid or liquid organic fertilizers. Background technique [0002] Organic fertilizer is an important fertilizer source for crops to increase yield and improve quality, and has the advantages of nutrient balance, soil fertility and soil improvement. In the process of agricultural production, people usually apply 8 to 10 kg of organic fertilizer as base fertilizer in the planting pit before fruit trees are planted. kg of organic fertilizer. The use of chemical fertilizers in pollution-free vegetables and A-grade green vegetables is limited, and the use of organic fertilizers is advocated; only organic fertilizers are allowed in the production of AA-grade green vegetables, and chemical fertilizers are not allowed. Therefore, organic fertilizer has an important position in agricultural producti...
