Problems solved by technology

[0004] The purpose of the present invention is to carry out advanced fermentation treatment on the straws in cold or severe cold areas after being pulverized and collected, and then carry out terminal treatments such as soil modification and improvement, paddy field seedling cultivation, and flower planting on the humus obtained after fermentation treatment. On the one hand, it solves the problem of land The organic matter content is too low. On the other hand, a large amount of straw produced every year has been thoroughly fermented. The straw has been effectively and fully recycled, and the occurrence of straw burning has been avoided. It has truly realized energy saving and environmental protection. Low cost, high benefit, economical and applicable, easy to promote and apply on a large scale

Embodiment 1

[0020] At present, aerobic fermentation of straw in cold or severe cold areas is done by stacking in the field or in the field before fermentation. The size of the straw pile is small, the temperature is not enough, and the humidity of the autumn-dried straw is not enough. Insufficient temperature makes it difficult to ferment straw. It is impossible to carry out small-scale fermentation of straw in the field in cold regions. Effective aerobic fermentation of straw requires an appropriate temperature and humidity environment.

[0021] A process for treating straw in cold regions, taking corn straw as an example, comprising the following steps:

[0022] Step 1: Straw crushing, collection and transportation

[0023] When the corn harvester harvests corn, the stalks are not sprayed on the ground after being crushed, but the crushed stalks are sprayed onto the vehicle bucket through the spray tube. Taking an administrative village as a unit, the straw is crushed and recycled in t...

Embodiment 2

[0030] After the advanced treatment of the straw in Example 1, high-grade humus is obtained, and these humus are mixed back into the soil to a thickness of about 6 cm, the soil will be repaired in the same year, the soil organic matter will increase significantly, and the problem of land compaction can be effectively solved , the sponge field will be produced. At present, the organic matter content in the soil of our country is less than 1%, and the organic matter content of the land in many foreign countries will be repaired if the organic matter is below 2%. Using the humus in this example to modify and improve the farmland can increase the organic matter content of some farmland in my country to More than 2%, the soil has been effectively repaired and improved. The production of corn stalks per hectare in Northeast my country is about 10 tons. After the straw produced in 5-6 mu of land is made into humus, one mu of land can be repaired and improved, and the land can be repai...

Embodiment 3

[0033] In paddy field production areas, soil must be excavated from dry fields to raise seedlings every year. Year after year, taking soil to raise seedlings has become the most difficult problem for rice farmers to solve. And rice seedlings are very prone to "blooming blight" and "bacterial wilt", if the soil quality is poor, other diseases will occur, and the humus in Example 1 can obtain excellent effects for cultivating rice seedlings after being treated. Fertile soil for rice seedlings. The fertile soil for rice seedlings can effectively prevent pests and diseases, and the growth of rice seedlings is much higher than that of rice seedlings cultivated with soil borrowed locally.

[0034] The terminal treatment process of the humus in the rice seedling fertilizer in Example 1 is as follows: the humus and biogas residue are pulverized by a pulverizer and then added to the soil and stirred evenly. The preferred mass percentages are respectively 80%, 10% and 10%. The above-me...

Abstract

The invention belongs to the technical field of energy saving and environmental protection, and specifically relates to a straw treatment process in cold regions. In an administrative village as a unit, straws are transported to a fermentation yard after crushing and recycling in fields; the stacking height of the crushed and recycled straws is not less than 4m, and the stacking width is not lessthan 10m; while stacking, a straw fermentation agent is sprayed into a straw stack, 5 kg-10 kg of clean water are sprayed into every cubic meter of straw stack, the humidity of the straws is 30%-45%,and the humidity of the straws after water spraying is 55%-65%; the stacked straws are fermented for 25-35 days; in a township or a town as a unit, firstly-fermented straws of every administrative village are centralized to a fermentation yard of the township or town for secondary centralized stacking fermentation, the firstly-fermented straws are stacked for centralized stacking fermentation through a lifting conveyor, the stacking height is 10m-15m, the fermentation time is 90-120 days, and after the second fermentation of the straws, fermentation product humus is obtained.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a straw treatment process in cold regions. Background technique [0002] On March 4, 2017, the relevant documents of the [Soil Pollution Prevention and Control Action Plan] under the State Council required all localities to take action. In severely polluted areas, forests and grasslands must be returned compulsorily. In many areas, crops are rotated and fallow. Heilongjiang has about 400,000 mu of farmland rotated every year. This is enough to illustrate the importance of agricultural environmental protection. In Northeast my country, the phenomenon of straw burning has been repeatedly banned. Governments at all levels have focused on the disposal of straw after the autumn harvest. Although various straw disposal technologies, methods and methods have been implemented, the results have been minimal. Large-scale burning, smoke everywh...
