Embodiment 1

[0056] Example 1 A method of indirect returning straw to the field in the wheat-corn rotation area of ​​the Huang-Huai-Hai region to link planting of characteristic plants.

[0057] Embodiment 1 adopts 1 hectare of field near the road, with a width of 22m and a length of 456m. For the convenience of operation, the rotting ditch is selected to be near the side of the road, and a space of 1.5m is reserved near the road. For the excavation of the heap rot ditch, after the corn is harvested, the corn stalks are first integrated into long strips by hand or by a hay rake for subsequent collection into the heap rot ditch. The pile rot ditch is opened into an inverted trapezoid with a width of 50 cm and a depth of 50 cm. The upper part is wider and the lower part is narrow. Part of the excavated soil is placed on both sides of the pile rot ditch, 20 cm above the ground, and the rest of the soil is evenly sprinkled on the field.

[0058] After the excavation of the heap rot ditch is co...

Embodiment 2

[0064] Example 2 The method of indirect return of Xinjiang cotton field straw to link planting characteristic plants

[0065] In this example, a cotton field of 10 hectares is used, with a width of 96 m and a length of 1500 m. During the cotton harvest period, the cotton stalks will be crushed by the cotton stalk crushing residual film recovery integrated machine and then transported into strips and piled in the field. At this time, 4 pile-rot ditches are opened in the north-south direction, and the distance between each pile-rot ditch is 22m. Sprinkle on the field.

[0066] After the excavation of the heap rot ditch is completed, the cotton stalks are sent into the heap rot ditch with a pick-up and side-throwing machine. In two years, the straw can be directly thrown into the heap rot ditch by combining the residual film recycling and the cotton stalk crushing and side throwing machine. Mix the decomposing bacteria equivalent to 1‰ of the straw amount plus 10 times the fine...

Embodiment 3

[0071] Example 3 The method of indirect return of corn stalks in the Northeast cornfield to link planting characteristic plants

[0072] In this example, a 5-hectare corn field is used, with a width of 90 m and a length of 830 m. During the corn harvest period, the corn stalks will be transported into strips and piled in the field after being crushed by an integrated machine for ear picking and straw crushing. At this time, 4 pile-rot ditches were opened in the north-south direction, and the distance between each pile-rot ditch was 21.5m. Sprinkle evenly on the field.

[0073] After the excavation of the pile rot ditch is completed, the corn stalks are sent into the pile rot ditch with a pick-up and side-throwing machine. Years can be combined with corn harvesting and straw crushing and side throwing all-in-one machine to directly throw straw into the pile rot ditch. Mix the decomposing bacteria equivalent to 1‰ of the straw amount plus 10 times the fine soil, and evenly spr...

Abstract

The invention discloses a method for planting featured plants by indirectly returning crop straw to the field and linking. The method comprises the following steps: layout and excavation of a composting ditch field, composting of straw in ditches, selection and layout of the featured plants, returning of a composting organic fertilizer to the field and whole-process management and harvesting. Crop straw field ditch composting is carried out according to local conditions, nectariferous plants suitable for the local economic or culture tourism are planted in composting ditches, the straw is put into the field composting ditches in the harvesting period, and when next-stubble crops are cultivated, the organic fertilizer in the composting ditches is taken out and applied to the field, so that straw composting and returning are achieved. The featured plants are planted on the sides of the composting ditches, on one hand, space can be fully utilized, on the other hand, featured plant belts have the economic production function and the ecological culture tourism value and can serve as ecological corridors for supplementing nutrition and providing shelters for natural enemy insects, the natural enemy insects protect field crops, so that use of chemical pesticides can be reduced, and the economic, sightseeing and natural enemy ecological corridors improve the additional value, reduce fertilizer and pesticides and improve the quality and efficiency.

Description

technical field [0001] The invention relates to the fields of straw resource utilization and agricultural green development, and specifically relates to a method for indirectly returning crop straws to fields and linking planting characteristic plants. Background technique [0002] my country is a large agricultural producer, with 1.8 billion mu of arable land, which is mainly used to grow crops. According to survey statistics, the total grain output in 2019 was 663.84 million tons. While producing grain, a large amount of crop straw was produced. Crop straw is the general term for the stems and leaves of mature crops, and it is the remaining part of crops after harvesting seeds, generally accounting for more than 50% of the biomass. Because it contains nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, it is an abundant and directly usable renewable resource. According to survey statistics, in 2015, the national straw theoretical resources amounted to ...
