Embodiment 1

[0024] (1) Rapeseed stalks are crushed into short rods less than 10cm; Ammonium bicarbonate is added with water to be mixed with an aqueous ammonium bicarbonate solution with a mass fraction of 8.5%, and then 6% surface activity of the aqueous ammonium bicarbonate solution weight is added in the aqueous ammonium bicarbonate solution The mixed solution was obtained by using a surfactant, and the surfactant was compounded with sophorolipid and sodium lignin sulfonate at a mass ratio of 1.5:4; the mixed solution was sprayed on the surface of the short stalks of rapeseed, and the spraying amount was 1 time of the quality of the short stalks of rapeseed, and the short stalks of rapeseed were sprayed. The stems are piled up and compacted, covered and sealed for 5 days, and the short stems of pretreated rapeseed are obtained;

[0025] (2) in the pretreatment rape short stalk of step (1), add 4% fermented bacterial agent of pretreatment rape short stalk weight to mix and obtain the sho...

Embodiment 2

[0029] (1) Rapeseed stalks are crushed into short rods less than 10cm; ammonium bicarbonate is added with water to be mixed with ammonium bicarbonate aqueous solution with a mass fraction of 10%, and then 4% surface activity of the ammonium bicarbonate aqueous solution weight is added in the ammonium bicarbonate aqueous solution The mixed solution was obtained by using a surfactant, and the surfactant was obtained by compounding sophorolipid and sodium lignosulfonate in a mass ratio of 2:5; the mixed solution was sprayed on the surface of the short stalks of rapeseed, and the spraying amount was 0.8 times the quality of the short stalks of rapeseed, and the short stalks of rapeseed were sprayed. The rods are piled up and compacted, covered and sealed for 5 days, and the pretreated rapeseed short rods are obtained;

[0030](2) in the pretreatment rape short stalk of step (1), add 2% fermented bacterial agent of pretreatment rape short stalk weight to mix and obtain the short sta...

Embodiment 3

[0034] (1) Rapeseed stalks are crushed into short rods less than 10cm; Ammonium bicarbonate is added with water to be mixed with ammonium bicarbonate aqueous solution with a mass fraction of 9%, and then 3.5% surface activity of the ammonium bicarbonate aqueous solution weight is added in the ammonium bicarbonate aqueous solution The mixed solution was obtained by using a surfactant, and the surfactant was obtained by compounding sophorolipid and sodium lignin sulfonate with a mass ratio of 1:3; the mixed solution was sprayed on the surface of the short stalks of rapeseed, and the spraying amount was 0.9 times the quality of the short stalks of rapeseed, and the short stalks of rapeseed were sprayed. The rods are piled up and compacted, covered and sealed for 7 days, and the pretreated rapeseed short rods are obtained;

[0035] (2) add 3.5% fermented bacterial agent of pretreatment rape short stalk weight in the pretreatment rape short stalk of step (1) and mix to obtain the sh...

Abstract

The invention relates to the technical field of agricultural waste recycling, and particularly discloses a rape straw returning method. The method comprises the following steps: crushing rape straws, and then adding a surfactant to an ammonium bicarbonate aqueous solution with the mass fraction of 8-10% to obtain a mixed solution; spraying the mixed solution to the surfaces of the short rape straws, stacking and compacting the short rape straws, and sealing and placing the rape straws for 5-7 days with a film to obtain pretreated short rape straws; adding a fermentation inoculant to the pretreated rape short straws to perform composting fermentation treatment for 5-7 days, then performing pile turning treatment on the piled rape short straw mixture, adding kaolin during pile turning treatment, performing uniform mixing, performing high-pile compaction, and continuing fermentation to obtain the decomposed rape straw organic fertilizer; and scattering the decomposed rape straw organic fertilizer on the surface of the field, and then performing rotary tillage on the decomposed rape straw organic fertilizer to be into the soil to finish returning the rape straws to the field. According to the rape straw returning method, the purpose that the rape straws are quickly decomposed and returned to the field is achieved, the soil fertility of the field can be improved, the application amount of chemical fertilizer is reduced, the yield of crops is increased, and the quality of the crops is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste recycling and reuse, and in particular relates to a method for returning rapeseed stalks to the field. Background technique [0002] my country is a big rapeseed country, and the rapeseed planting area and rapeseed production account for about 20% of the world's total. Rapeseed is the most important oil crop in my country and plays a key role in ensuring the safety of edible oil supply in China. In recent years, with the vigorous development of rural tourism and agricultural tourism in my country, rapeseed has become one of the important tourism resources. Every year, various "rape flower festivals" attract a large number of tourists. Now rape is not only an important source of oil crops, but also a tourism resource, which plays an important role in promoting the development of rural economy. [0003] Rapeseed planting produces a large amount of agricultural waste - rapeseed stalks wh...
