Embodiment 1

[0033] Shajiang Black Soil Inspired Straw Misalignment Wheel Return Full Tillage Layer Fertilization Method:

[0034] The field experiment of straw misalignment and full-plow layer fertilization in Shajiang black soil was carried out in 2017 at the Taihe Modern Agriculture Comprehensive Experimental Station in Taihe County, Anhui Province. The experiment set up nine treatments (Table 1) and was continuously monitored until 2020.

[0035] Table 1 Experimental treatment of straw dislocation wheel returning full tillage layer to fertilize field

[0036]

[0037] Such as figure 1 As shown, the wheat yield data in 2020 shows that compared with the control treatment of treatment 6 without returning to the field + no fertilization, the treatment of 7 misplaced rounds + biostimulants + chemical fertilizers increased wheat production by 195.85%, and treatment 8 misplaced rounds + chemical fertilizers increased production 240.56% of wheat, 32.92% of wheat yield increased by treatmen...

Embodiment 2

[0041] Huanghuaihai tidal cinnamon soil stimulation method of straw dislocation wheel and full tillage layer fertilizer method:

[0042] The field verification test was carried out in Luancheng, Hebei Province as a typical pilot site (Table 2). In order to facilitate mechanized operation, the activator I used was 100 kg / mu of yellow humic acid substances, and the straw returned in the wheat season was corn, and the straw returned in the corn season was wheat. The trial started in 2016 and has been in field trials for four years. The experimental treatments included: misplaced wheel return treatment, straw removal and conventional straw return, that is, corn stalks were returned to the field by rotary plowing during the wheat season, and wheat straw was covered and returned to the field during the corn season as a control treatment. Consistent agricultural cooperatives and no fertilization, straw returning to the field with additional activator application treatment, straw rem...

Abstract

The invention relates to an excitation type straw dislocation wheel returning full plough layer fertilization method. The excitation type straw dislocation wheel returning full plough layer fertilization method comprises the following steps that previous crushed corn straws are deeply ploughed by using a deep ploughing plough in a wheat season in the first year, and uniformly mixed to a 35 cm soil layer; the crushed corn straws are shallowly rotated by using a rotary cultivator in the wheat season in the second year, and uniformly mixed to a 20 cm soil layer; the crushed corn straws are shallowly rotated by using a rotary cultivator in the wheat season in the third year, and uniformly mixed to a 15 cm soil layer; the crushed corn straws are shallowly rotated by using a rotary cultivator in the wheat season in the fourth year, and uniformly mixed to a 20 cm soil layer; the crushed corn straws are shallowly rotated by using a rotary cultivator in the wheat season in the fifth year, and uniformly mixed to a 15 cm soil layer; and in the wheat season of the sixth year, the crushed corn straws are shallowly rotated by using a rotary cultivator and uniformly mixed to a 15 cm soil layer, the previous wheat straws in the corn season every year are crushed to cover the surface layer of the soil, and then cyclically and circularly fertilizing is carried out every six years as a staggered wheel. The organic matter level of the high-strength planting soil is improved; the straw returning problem is solved, and the soil structure is improved; and the fertility of a lower plough layer is improved, nutrient backflow is enhanced, and the supply proportion of organic nutrients is increased.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a stimulating method for fertilizing the whole plow layer with straw dislocation wheels. Background technique [0002] Straw returning is an effective measure to improve soil and increase soil productivity. One is to put the straw into the soil after composting and retting; the other is to chop the straw and scatter it on the surface of the ground after the crops are harvested, turn it over and press it with a plow, and return it directly to the field, which can improve the physical properties of the soil and promote the formation of soil aggregate structure , Increase air permeability, water permeability, and fertilizer retention capacity, thereby improving soil fertility. To sum up, improving soil organic matter is the core of fertilization, but due to the ecological restoration process of the high-intensity planting soil in the Yellow-Huai-Hai and Northea...
