Problems solved by technology

However, after the operation of these machines and tools, the efficiency of crop straw decomposing and returning to the field is low, which will cause a large amount of residual straw to entangle and block the ditch openers of the planting machines during sowing in the next year, which restricts the application and promotion of straw returning machinery

Embodiment 1

[0016] Embodiment 1: A method for quickly decomposing and returning field straw stubble to the field, comprising the following steps:

[0017] 1) Activation of the rot agent: divide the rot agent made of 40% yeast, 35% fermented filamentous bacteria and 25% photosynthetic bacteria into two parts, the first part of the rot agent and water The blending ratio is 1:600; the blending ratio of the second stalk rot agent to water is 1:300; the two stalk rot solutions mixed with water are respectively activated at 38°C for 10 hours;

[0018] 2) Use the combined operation machine for straw returning to the field and pesticide spraying to remove the stubble remaining in the field. The height of the stubble removal in the field is 10 to 12 cm; at the same time, spray the first part of humus agent solution described in step 1, and then remove the stubble that has been removed. Stay in the field for 1.5 days; the rotten agent solution mixed with the first part of the rotten agent and water...

Embodiment 2

[0025] Embodiment 2: A method for quickly decomposing and returning field straw stubble to the field, comprising the following steps:

[0026] 1) Activation of the rot agent: divide the rot agent made of 40% yeast, 35% fermented filamentous bacteria and 25% photosynthetic bacteria into two parts, the first part of the rot agent and water The blending ratio is 1:500; the blending ratio of the second stalk rot agent and water is 1:200; the two stalk rot solutions mixed with water are respectively activated at 35°C for 12 hours;

[0027] 2) Use the combined operation machine for straw returning to the field to remove stubble from the stubble remaining in the field. The stubble height of the stubble in the field is 9-11 cm; at the same time, spray the first part of the humic agent solution described in step 1, and then remove the stubble that has been stubbled. Stay in the field for 2 days; the first stalk rot solution mixed with water is 200L / hm 2 spraying;

Embodiment 3

[0034] Embodiment 3: A method for quickly decomposing and returning field straw to the field, comprising the following steps:

[0035] 1) Activation of the rot agent: divide the rot agent made of 40% yeast, 35% fermented filamentous bacteria and 25% photosynthetic bacteria into two parts, the first part of the rot agent and water The blending ratio is 1:700; the blending ratio of the second part of rotten agent to water is 1:400; the two parts of rotten agent solution mixed with water are respectively activated at 35°C for 8 hours;

[0036] 2) Use the combined operation machine for straw returning to the field and pesticide spraying to remove the remaining stubble in the field, and the height of the stubble removal in the field is 10-15 cm; at the same time, spray the first part of humus agent solution described in step 1, and then remove the stubble that has been removed. Stay in the field for 1 day; the first rot rot solution mixed with water is 250L / hm 2 spraying;

Abstract

The invention relates to the technical field of protective farming, in particular to a method for performing returning treatment on left stubbles of straws. A method for performing quick decomposition and returning treatment on left stubbles of field straws comprises the following steps of: activating a stalk rot agent; cleaning the left stubbles of the field straws by using a straw returning andspraying combined operation machine; and embedding the left stubbles of the straws which are retained in a field by using a straw embedding and quick decomposing combined operation machine. By the method, the problem of the quick decomposition and returning of the left stubbles of the field straws after mechanical harvesting can be solved in an accelerated way, winding and blocking which are caused by the left stubbles of the straws to an opener of a seeding machine are prevented from influencing the operational efficiency of the field, and the content of organic matters in soil, the fertilization soil productivity and the yield of crops can be improved.

Description

technical field [0001] The invention relates to the technical field of conservation tillage, in particular to a treatment method for returning stubble to the field. Background technique [0002] In recent years, most areas in northern my country have adopted combine harvesters to achieve crop harvesting. Therefore, it is urgent to solve the problem of straw harvesting in the field. Mechanized straw returning to the field can timely deal with a large amount of crop straw left in the field after mechanical harvesting, avoid environmental pollution caused by straw burning, and can increase soil organic matter content, fertilize soil fertility, and increase crop yield. In order to return the stubble to the field, my country has developed a variety of crop straw returning machines, such as straw crushing and returning machines, reverse rotary tillage and stubble removal machines, etc. However, after the operation of these machines and tools, the efficiency of crop straw decompos...
