Embodiment 1
[0029] Such as figure 1 , a method for cultivating and planting corn in the black soil region of Northeast China, comprising the following non-sequential steps:
[0030] A. Straw returning to the field for conservation tillage: After the crops are harvested in autumn, the grass will be collected and rowed;
[0031] B. When sowing, increase the number of plants through the effect of wide and narrow rows. When the original ridge spacing is about 65 cm, adjust the narrow row spacing to 42-45 cm and the wide row spacing to more than 85 cm;
[0032] C. Increase the application of organic bacterial fertilizer: the organic bacterial fertilizer includes base fertilizer and mouth fertilizer; the base fertilizer uses 1000g, 40% organic and inorganic blended slow-release fertilizer; the mouth fertilizer uses 160g organic bacterial fertilizer;
[0033] D. Use the herbicide treated by the second dilution method for weeding;
[0034] E. Subsoiling and breaking the plow bottom layer i...
Embodiment 2
[0036] This example explains the straw returning protective tillage:
[0037] After the crops are harvested in autumn, the grass is collected in time. When the straw is particularly large, the straw is packed in an appropriate amount, but the straw is mainly returned to the field to increase the content of soil organic matter and fertilize the soil. This embodiment selects subsoiling in autumn, thereby improving the ground temperature when sowing in spring next year. When subsoiling in autumn, only the leisure bands sown in the next year are subsoiled, and the sowing bands in the coming year cannot be loosened, so as not to affect the moisture content during sowing in spring next year.
Embodiment 3
[0039] Present embodiment explains sowing time and sowing method:
[0040] Sow seeds in time during Grain Rain. When the stalks are blown by the wind, hang a front return machine in front of the sowing truck for secondary collection. Lowering the weed wheel of the no-tillage machine to one level can prevent the phenomenon of stubble and other padding and affect the number of plants to be planted, and can peel off the dry soil on the surface to ensure moisture content. At the same time, it can be easily watered in the early spring.
[0041] When the type of cultivated land is windy and sandy land, the weed wheel of the no-tillage machine can be adjusted or not adjusted according to the situation.
[0042] Sow in wide and narrow rows. When the original ridge spacing is about 65 cm, the narrow row spacing should be adjusted to 42-45 cm, and the wide row should be more than 85 cm, so as to facilitate deep loosening in summer and ensure the edge row effect. Since the base fertiliz...
