Scope

Main Technical Content: 3 Terms and Definitions This document does not define any terms or definitions that require clarification. 4 Production Technology 4.1 Straw Collection 4.1.1 Collection Time The collection of straw must be completed within one week after the harvest of fresh corn cobs. If it rains, the collection should be postponed until the weather is clear for at least one day; if it is cold and frosty, the collection work should be suspended to avoid the straw from freezing. 4.1.2 Collection Methods The collection can be carried out by mechanical or manual methods, and the stubble height of the straw should be no less than 15 cm. At the same time, efforts should be made to avoid mixing impurities such as soil, stones, and weeds into the straw to maintain its purity and quality. 4.2 Shearing and Crushing 4.2.1 Shearing Requirements The collected fresh corn straw should be sheared into 2-5 cm-long pieces by machinery to provide suitable materials for subsequent fermentation and cultivation. 4.2.2 Crushing Control The sheared straw should be crushed into even-sized particles to facilitate the balanced decomposition of nutrients during the fermentation process. 4.3 Cultivation Material Preparation 4.3.1 Cultivation Material Formula The crushed fresh corn straw and other auxiliary materials should be mixed according to the following proportions: 70% fresh corn straw, 20% wheat bran, 5% corn flour, 1% gypsum powder, 2% lime, and 2% calcium phosphate. The proportions can be adjusted according to different cultivation needs. 4.3.2 Pre-processing Before preparing the cultivation material, the pre-wetted straw should be pre-processed 2-3 days in advance to achieve a water content of 60%-65%. 4.3.3 Mixing and Stirring The pre-wetted straw and other auxiliary materials should be mixed evenly using a mechanical mixer to avoid localized over- or under-mixing. During the operation, efforts should be made to prevent clumping or s
