Problems solved by technology

Cakes are stacked and retting, soaked and fermented until they are used. The time is too long, because applying them before they are fully fermented will burn the roots of the crops, and it is inconvenient to transport them to the field for use, and it is impossible to transport them to places with steep hillsides. Heat preservation is required during the retting process, which increases production costs
There are also a small number of cakes that are directly sprinkled on the field and let them decompose naturally to be used as fertilizers for crops. In this case, because the cakes cannot be decomposed for a long time, the organic nutrients will be naturally lost after being washed by rain and oxidized by air. Low

Embodiment 1

[0028] Example 1 Accelerated Fermentation Experiment of Rapeseed Cake Fermentation Agricultural Organic Manure

[0029] Test method: Mix koji, fertilizer nitrogen, and superphosphate for brewing evenly, add water I to make mother liquor, stir evenly, add hard lumps of rapeseed cake to the mother liquor until stirred and soaked, soak for 25 days, then add water II Stir to soak and ferment to maturity. The time required for the rapeseed cake to ferment to mature was measured, and the specific experimental conditions and experimental results are shown in Table 1 below.

[0030] Table 1 Experimental conditions and experimental results

[0031]

[0032]

[0033]The above-mentioned experimental results show that: in the preparation method, koji, chemical fertilizer nitrogen and superphosphate play a role in accelerating fermentation in the fermentation process of rapeseed cake, adding only one or both of them will The fermentation time is extended to 30-43 days. When koji m...

Embodiment 2

[0035] Example 2 Preparation of rapeseed cake fermented agricultural organic fertilizer

[0036] After mixing 20g of koji medicine for brewing, 2kg of fertilizer nitrogen (30% by weight of pure nitrogen), and 80kg of superphosphate, add 400kg of water to make a mother liquor, stir evenly, and add rapeseed cake to the mother liquor Stir and soak the lumps until soaked, soak for 15 days, then add water until stirred and soaked, ferment at 20°C for 10 days or 31°C for 6 days or 5°C for 20 days to obtain the rapeseed cake fermented agricultural organic fertilizer.

[0037] Or mix 10g of koji medicine for brewing, 1.2 catties of fertilizer nitrogen (20% by weight of pure nitrogen), and 28 catties of superphosphate, then add 160 catties of water to make a mother liquor, stir evenly, and add rapeseed to the mother liquor Stir and wet the hard cake, soak for 20 days, then add water until it is stirred and soak, ferment at 30°C for 7 days or 37°C for 3 days or 19°C for 15 days to obtain...

Embodiment 3

[0045] Embodiment 3 organic fertilizer is used for the cultivation of paddy rice

[0046] The experimental site is Gao Countryside, Shiban Town, Jiulongpo, Chongqing City. The organic fertilizer prepared in Example 2 is used as the base fertilizer of rice. The amount of organic fertilizer is 70 jin per mu, supplemented with 50 jin of conventional chemical fertilizer, and the rice with 120 jin of conventional chemical fertilizer per mu is used as a control. Sprinkled on the ground, other management measures are the same. The result shows: the rice that uses the organic fertilizer of the present invention (experimental group) as the base fertilizer has no root burning phenomenon, and compared with the rice (control group) that routinely applies chemical fertilizers, the plant height, stem diameter, and panicle shape of the experimental group's rice are all significantly improved. Advantages, the final yield has increased by 20%, and the rice grains are full, the rice tastes sof...

Abstract

The invention discloses a rape cake-fermentation agricultural organic fertilizer which is prepared with the method comprising the following steps: uniformly mixing the materials of distiller's yeast for wine making, chemical fertilizer nitrogen and calcium superphosphate, adding water into the mixture to form a mother liquor, uniformly stirring, adding hard rape cake lumps into the mother liquor and wetting the hard rape cake lumps through stirring, soaking for 15-30 days, and then adding water to enable the rape cake lumps to be wetted through stirring, and fermenting for 3-20 days, so as to obtain the rape cake-fermentation agricultural organic fertilizer. The rape cake-fermentation agricultural organic fertilizer provided by the invention is a high-content organic matter fertilizer which has the advantages of short production period, low cost, zero contamination, good convenience in transportation and the like. The invention further provides application of the rape cake-fermentation agricultural organic fertilizer in planting of grain crops, vegetable crops, industrial crops or fruit crops. The rape cake-fermentation agricultural organic fertilizer can effectively improve the quality and yield of various agricultural products, and has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production; more specifically, the invention relates to a rapeseed cake fermented agricultural organic fertilizer and a preparation method and application thereof. Background technique [0002] Since ancient times, various kinds of cakes have been abundant in my country, especially rapeseed cakes. Farmers usually steam and grind rapeseed cakes into powder, add water to ferment naturally, and use them as fertilizers. Because cakes contain a lot of organic matter and trace elements, they are extremely beneficial to the growth of various crops. Regardless of universities, research institutes, enterprises, farmers or individuals, the production and creation of crop brands are inseparable from the application of rapeseed cake fertilizer, combined with other fertilizers. [0003] Before the 1980s, the rapeseed cake was left over from manual pressing of vegetable oil. The rapeseed cake was as hard a...
