Problems solved by technology

Since the organic flush fertilization adds urea to change the c / N ratio, it does not belong to the strict sense of organic flush fertilization and cannot be used in the production of organic agricultural products
Existing organic fertilizer production technology is not enough to make flushing fertilization rich in available nutrients (except amino acids), which greatly limits the production of organic flushing fertilization products, and it is even more impossible to diversify the nutrient distribution ratio of organic flushing fertilization. suitable for different crops

Embodiment 1

[0049] Embodiment 1: Organic flushing fertilization, the components are as follows:

[0050] 60 kg of protein hydrolyzate, 20 kg of phytic acid hydrolyzate, and 20 kg of plant ash extract.

[0051] The preparation method is as follows:

[0052] (1) Take 300 kg of fresh corn germ oil residue and add it to the container, add 1500 kg of water, adjust the pH value to 8.0, add 0.5 kg of lipase preparation (SUKALip PW12.5), stir for 5 minutes, and place it at 38°C for 48 hours , stirring once every 2 hours during this period, each time for 3 minutes, to obtain lipolysis oil residue; set aside;

[0053] (2) Take 200 kg of lipolytic oil residue prepared in step (1), boil for 15 minutes, adjust the pH value to 7.0 after cooling, add 0.01 kg of neutral protease preparation SUKAPro NEPW50, stir for 4 minutes, and place it at 58°C 2 hours, stirring once every 0.5 hours during the period, 2 minutes each time, spray drying after the end, to obtain protein hydrolyzate; set aside;

[0054]...

Embodiment 2

[0058] Embodiment 2: organic flush fertilization, composition is as follows:

[0059] 25 kg of protein hydrolyzate, 50 kg of phytic acid hydrolyzate, and 25 kg of plant ash extract.

[0060] The preparation method is the same as in Example 1, except that the oil residue is a 1:1 composition of peanut oil residue and rapeseed oil residue.

[0061] The fertilizer in this embodiment is suitable for crops that require more phosphorus nutrition, such as root and tuber crops, sugar crops, and leguminous crops.

Embodiment 3

[0062] Embodiment 3: organic flush fertilization, composition is as follows:

[0063] 30 kg of protein hydrolyzate, 35 kg of phytic acid hydrolyzate, and 35 kg of plant ash extract.

[0064] The preparation method is as follows:

[0065] (1) Take 300 kg of fresh soybean oil residue and put it into a container, add 1000 kg of water, adjust the pH value to 7.6, add 1.0 kg of lipase preparation (SUKALip PW10), stir for 5 minutes, and place it at 44°C for 43 hours. Stir once every 2 hours, 3 minutes each time, to obtain lipolysis oil residue; set aside;

[0066] (2) Take 300 kg of lipolysis oil residue prepared in step (1), boil for 10 minutes, adjust the pH value to 7.5 after cooling, add 0.05 kg of neutral protease preparation SUKAPro NE PW50 and NE PW30 in a mass ratio of 1:1 The composition was stirred for 4 minutes, and placed at 53°C for 3 hours, during which it was stirred every 0.5 hours for 2 minutes each time, and spray-dried after the end to obtain a protein hydrolyza...

Abstract

The invention relates to a preparation method of an organic water flushed fertilizer. According to the preparation method of the water flushed fertilizer, oil residue is taken as the raw material; a lipase preparation, a neutral protease preparation and a phytase preparation are used for decomposing effective nutritional ingredients in the oil residue; protein hydrolysate, phytase hydrolysate and plant ash extract are used for preparing the water flushed fertilizer according to a ratio. The organic water flushed fertilizer is abundant in available nitrogen, available phosphorus and available potassium and capable of meeting the requirements on nutrients of different crops; after performing field experiment, a good yield-increasing effect is achieved.

Description

technical field [0001] The invention relates to flush fertilization, in particular to a method for preparing organic flush fertilization, and belongs to the technical field of fertilizer production. Background technique [0002] Flush fertilization is a kind of fertilizer that is applied to the soil with watering during the growing period of crops. It requires good solubility and fast fertilizer efficiency, which can meet the requirements of large amounts of nutrients needed by crops during the rapid growth period. At present, inorganic flushing fertilization and organic-inorganic compound flushing fertilization are the main types of fertilization, and some biological flushing fertilizations containing microorganisms are also used. There are almost no organic flushing fertilizations without adding any chemically synthesized fertilizers. CN1789218A (CN200510045090) discloses an organic flushing fertilization and a production method thereof. The raw material composition of th...
