Problems solved by technology

However, the existing methods basically increase the lactic acid content by artificially adjusting the content of lactic acid bacteria or the fermentation coefficient. Obviously, this still has the problem of inconvenient operation, especially not suitable for farmers to operate

Embodiment 1

[0022] Example 1. A mixed silage process of rice straw and Daheishan Coix coix, the steps include: cutting off the roots of the harvested fresh straw and then drying, controlling the moisture content of the dried straw to 11.5±0.2%, kneading the dried straw with a kneading machine Shredded and cut into segments with a length of 3±0.5cm and a width of 1-3mm; remove the fresh Daheishan Coix coix and cut it into segments with a length of 3-5cm. Moisture control is 88 ± 2%; Gained straw segment is mixed with the gained Daheishan Coix segment according to the weight ratio of 2:8, and mixed thoroughly to obtain a mixture; the gained mixture is placed in a silage container, and the compacted density is 630kg / m 3 , and carry out vacuum treatment, and immediately package after vacuum; put the packaged silage in a cool environment with a temperature of 10-18° C. to ferment for 60 days.

Embodiment 2

[0023] Example 2. A mixed silage process of rice straw and Daheishan Coix coix, the steps include: cutting off the roots of the harvested fresh straw and then drying, controlling the moisture content of the dried straw to 11.5±0.2%, kneading the dried straw with a kneading machine Shredded and cut into segments with a length of 3±0.5cm and a width of 1-3mm; remove the fresh Daheishan Coix coix and cut it into segments with a length of 3-5cm. Moisture control is 88 ± 2%; Gained straw segment is mixed with the gained Daheishan coix segment according to the weight ratio of 1:9, and mixed thoroughly to obtain a mixture; the gained mixture is placed in a silage container, and the compacted density is 630kg / m 3 , and carry out vacuum treatment, and immediately package after vacuum; put the packaged silage in a cool environment with a temperature of 10-18° C. to ferment for 60 days.

Embodiment 3

[0024] Example 3. A mixed silage process of rice straw and Daheishan Coix coix, the steps include: cutting off the roots of the harvested fresh straw and then drying, controlling the moisture content of the dried straw to 11.5±0.2%, kneading the dried straw with a kneading machine Shredded and cut into segments with a length of 3±0.5cm and a width of 1-3mm; remove the fresh Daheishan Coix coix and cut it into segments with a length of 3-5cm. Moisture control is 88 ± 2%; Gained rice straw segment is mixed with gained Daheishan Coix coix segment according to the weight ratio of 3:7, mixes well, obtains mixture; Gained mixture is placed in the silage container, and the compaction density is 630kg / m 3 , and carry out vacuum treatment, and immediately package after vacuum; put the packaged silage in a cool environment with a temperature of 10-18° C. to ferment for 60 days.

Abstract

The invention provides a method for improving lactic acid in silage, and a straw and coix seed mixed silage process. Air-dried straw segments and fresh Coix lacryma-jobi L. cv. Daheishan segments with green stems and leaves are mixed in proportion, and then silage is carried out in an anaerobic environment. By the adoption of the scheme, under the condition that no auxiliary materials or lactic acid bacteria are added, the lactic acid content in the Coix lacryma-jobi L. cv. Daheishan silage can be increased, the silage operation process is greatly simplified, the operation difficulty is greatly lowered, the silage cost is greatly reduced, and Da Haishan coix lacryma-jobi can be silage with Coix lacryma-jobi L. cv. Daheishan as the main material.

Description

technical field [0001] The invention belongs to the technical field of coix silage, and in particular relates to a method for increasing lactic acid of (Daheishan coix) silage and a process for mixing rice straw and coix silage. Background technique [0002] Daheishan coix, also known as Daheishan coix grass, is a new forage variety selected from traditional coix by experts from Sichuan Agricultural University in recent years. It is a perennial grass plant. Coix coix for feeding in Daheishan has a sweet taste, no burrs, livestock like to eat it, and high utilization rate. It is a high-quality forage grass with high feeding value. Feeding herbivores can produce good economic benefits. It is an excellent grass in tropical and subtropical regions. Green forage grass species. It is also a kind of perennial green feed with long growth period, fast growth speed, strong regeneration ability and high yield, and has strong adaptability and stress resistance. It can effectively cont...
