Embodiment 1

[0036] A method for cultivating wheat, rapeseed and corn in rotation, comprising the steps of:

[0037] A. Wheat planting

[0038] Sow wheat in the middle and late March of the first year, sow wheat at an average day and night temperature of 0-2°C, sow at the top when the surface soil is thawed at 5-7 cm, plant evenly at a row spacing of 15 cm, sow at a depth of 3-5 cm, and sow at a rate of 20-25 kg / mu;

[0039] B. Rapeseed planting

[0040] After the wheat is harvested, rapeseed is sown. The sowing rate is 1-1.5 kg / mu. When the seedling height is 30-50cm, the above-ground part of the rapeseed is crushed, and all the crushed rapeseed is plowed into the soil with a plowing depth of 15-20cm.

[0041] C. to plant corn

[0042] In the second year, corn is sown from late April to mid-May, and the ground temperature of 5-10 cm in the underground layer is 7°C-8°C. Sow after plowing and compacting. The sowing depth is 3-4cm, and the seedlings are preserved per hectare. strain.

Embodiment 2

[0044] A method for cultivating wheat, rapeseed and corn in rotation, comprising the steps of:

[0045] A. Wheat planting

[0046] Sow wheat in the middle and late March of the first year, sow wheat at an average day and night temperature of 0-2°C, sow on top when the surface soil is thawed at 5-7 cm, and improve the ventilation, fertilization, and lighting efficiency of the lower part of the crop. In step A, large and small rows can be used. Sowing wheat, the large row is 18 cm, the small row is 12-13 cm, the sowing depth is 3-5 cm, and the sowing rate is 20-25 kg / mu;

[0047] B. Rapeseed planting

[0048] After the wheat is harvested, rapeseed is sown. The sowing rate is 1-1.5 kg / mu. When the seedling height is 30-50cm, the above-ground part of the rapeseed is crushed, and all the crushed rapeseed is plowed into the soil. The plowing depth is 15-20cm. And lay plastic film on the plot, the edge of the plastic film is compacted with soil belt, and the thickness of the plasti...

Embodiment 3

[0052] A method for cultivating wheat, rapeseed and corn in rotation, comprising the steps of:

[0053] A. Wheat planting

[0054]Sow wheat in the middle and late March of the first year, sow wheat at an average day and night temperature of 0-2°C, sow at the top when the surface soil is thawed at 5-7 cm, plant evenly at a row spacing of 15 cm, sow at a depth of 3-5 cm, and sow at a rate of 20-25 kg / mu;

[0055] B. Rapeseed planting

[0056] After the wheat is harvested, rapeseed is sown. The sowing rate is 1-1.5 kg / mu. When the seedling height is 30-50cm, the above-ground part of the rapeseed is crushed, and all the crushed rapeseed is plowed into the soil. Spray water to soak the surface soil of the plot, and lay plastic film on the plot, the edge of the plastic film is compacted with soil tape, and the thickness of the plastic film is 0.006-0.008mm;

[0057] C. to plant corn

[0058] In the second year, corn is sown from late April to mid-May, and the ground temperature ...

Abstract

The invention relates to the technical field of crop rotation culture, in particular to a wheat, oilseed rape and maize crop rotation cultivation method. The method comprises the steps that wheat, oilseed rape and maize crop rotation is performed in a field, due to the oilseed rape planting water-logged compost link, the application amount of chemical synthesis fertilizer can be greatly lowered, the current situation that two cropping systems of crops are not sufficient and single cropping is abundant in a Northern loess plateau dry land planting area is changed, due to the water-logged compost link, the soil section nitrogen supply capability can be improved, the available phosphorus, available iron and manganese contents are effectively increased, and the activities of sucrose, urease, alkaline phosphatase and proteinase are improved to different extents; compared with continuous cropping, due to crop rotation is performed on green manure crops of growing after wheat, the soil microbial diversity can be remarkably improved, the stability of an agroecological system is affected, the soil carbon cycling and phosphorus mobilization are accelerated, and the effective soil nutrient content is increased; meanwhile, the soil nitrogen mineralization rate is lowered, and stability and accumulation of soil nitrogen are promoted, so that the soil fertility level is increased, and the application amount of the chemical fertilizer is decreased.

Description

technical field [0001] The invention relates to the technical field of crop rotation cultivation, in particular to a method for crop rotation cultivation of wheat, rapeseed and corn. Background technique [0002] Crop rotation refers to the planting method of planting different crops or multiple crop combinations sequentially between seasons and years on the same field. It is a biological measure that combines land use and land cultivation. It is conducive to the balanced use of soil nutrients and the prevention and control of diseases, insects, and weeds; it can effectively improve the physical and chemical properties of the soil and regulate soil fertility. It is consistent with the concept of "environmentally friendly planting and green food" advocated in recent years, but the existing crop rotation technology simply discloses which crops are suitable for crop rotation. Due to various conditions such as geographical distribution, soil nutrients, uneven temperature and hum...
