Embodiment 1

[0023] A method for stocking whole plant corn, comprising the steps of:

[0024] S1. Harvest the whole plant corn with a stubble of 15cm, and obtain the stockpiled raw material with a moisture content of 65% after crushing, and transport the stockpiled raw material to the stockyard within 6 hours; among them, the stockpiled raw material includes a length of 0.9-1.9cm corn stalks, and if the transportation time exceeds 4 hours, add microbial additives during crushing, and add preservatives during transportation;

[0025] S2. Select a hardened site with a thickness of not less than 20cm in the storage yard, use 5% iodophor solution or 2% bleach solution to clean and disinfect the hardened site, and then use the pressure pit machine to carry out multi-layer pressure pit storage to obtain conical Heap storage body, and the density of the conical heap storage body is not less than 750kg / m 3 1. The inclination of the inclined plane is 20°; specifically, when storing in a multi-laye...

Embodiment 2

[0030] A method for stocking whole plant corn, comprising the steps of:

[0031] S1. Harvest the whole plant corn with a stubble of 20 cm, and obtain the stockpiled raw material with a moisture content of 68% after crushing, and transport the stockpiled raw material to the stockpiling yard within 6 hours; wherein, the stockpiled raw material includes a length of 0.9 to 1.9 cm corn stalks, and if the transportation time exceeds 4 hours, add microbial additives during crushing, and add preservatives during transportation;

[0032] S2. Select a hardened site with a thickness of not less than 20cm in the storage yard, use 5% iodophor solution or 2% bleach solution to clean and disinfect the hardened site, and then use the pressure pit machine to carry out multi-layer pressure pit storage to obtain conical Heap storage body, and the density of the conical heap storage body is not less than 750kg / m 3 1. The inclination of the slope is 25°; specifically, when storing in a multi-laye...

Embodiment 3

[0037] S1. Harvest the whole plant corn with stubble of 30cm, and obtain the stockpiled raw material with a moisture content of 70% after crushing, and transport the stockpiled raw material to the stockpiling yard within 6 hours; among them, the stockpiled raw material includes a length of 0.9-1.9cm corn stalks, and if the transportation time exceeds 4 hours, add microbial additives during crushing, and add preservatives during transportation;

[0038] S2. Select a hardened site with a thickness of not less than 20cm in the storage yard, use 5% iodophor solution or 2% bleach solution to clean and disinfect the hardened site, and then use the pressure pit machine to carry out multi-layer pressure pit storage to obtain conical Heap storage body, and the density of the conical heap storage body is not less than 750kg / m 3 1. The inclination of the inclined plane is 30°; specifically, when storing in a multi-layer press pit, ensure that the thickness of each layer does not exceed 1...

Abstract

The invention belongs to the technical field of whole-plant corn stacking and storage, and discloses a whole-plant corn stacking and storage method which comprises the following steps: harvesting whole-plant corn, crushing to obtain stacking and storage raw materials, and transporting the stacking and storage raw materials to a stacking and storage field within 6 hours; wherein the piled and stored raw materials comprise corn straws with the length of 0.9 to 1.9 cm; a hardened field with the thickness not smaller than 20 cm is selected in the stacking and storing field, multi-layer cellar pressing stacking and storing are conducted through cellar pressing machinery, a conical stacking and storing body is obtained, and the inclination degree of the inclined face of the conical stacking and storing body is 20-30 degrees; covering a sealing film on the conical stacking and storing body, and compacting the edge of the sealing film, so that the conical stacking and storing body is sealed and fermented; in conclusion, according to the method, full fermentation of piled raw materials is achieved through multi-layer pit pressing piled storage, the operation process is simple, reasonable, scientific and normative, and the corn silage prepared under the high-moisture condition has the advantages of being dark green in color, good in palatability, high in digestibility, small in nutrient substance loss and the like.

Description

technical field [0001] The invention belongs to the technical field of whole-plant corn heap storage, and in particular relates to a whole-plant corn heap storage method. Background technique [0002] At present, most of the processing of whole corn in China is to harvest it and dry it properly, and then collect silage for winter livestock. However, the moisture content of the whole plant corn is generally high (between 60% and 80%), so it is very easy to rot and deteriorate during storage. Contents of the invention [0003] In view of this, in order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide a kind of whole plant corn stockpiling method. [0004] Specifically, the reason why the whole plant corn is easy to rot is not only the raw material itself, but also the stacking state and internal structure of the straw. Generally, when stacked naturally, due to the characteristics of its stem struct...
