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...

Abstract

The invention discloses a corn cultivation and planting method for a northeast black soil area. The corn cultivation and planting method comprises the following non-sequential execution steps of A, performing straw returning protective cultivation, namely after crop autumn harvest, performing grass raking and row collecting; B, during sowing, arranging a front row returning machine to a sowing vehicle, and carrying out secondary row collection; C, during sowing, increasing the number of plants through the wide-narrow row effect, and when the original ridge spacing is about 65 cm, adjusting thenarrow row spacing to 42-45 cm and adjusting the wide row spacing to 85 cm or above; D, additionally applying organic bacterial fertilizer, wherein the organic bacterial fertilizer comprises base fertilizer and seed fertilizer, 1000g of organic-inorganic blended slow-release fertilizer with the content of 40% is used as the base fertilizer, and 160g of organic bacterial fertilizer is used as theseed fertilizer; E, performing weeding by using herbicide treated by a secondary dilution method; and F, in summer, performing deep scarification for breaking a plow pan, namely performing deep scarification on a flat land parcel to 40 cm through a side column type subsoiler, and breaking the plow pan. According to the method, the purposes of standardized production of corn cultivation and planting and cost reduction and yield increase are achieved.

Description

technical field [0001] The invention relates to the field of corn planting, in particular to a corn planting method used in the black soil region of Northeast China. Background technique [0002] Corn is one of the three major food crops in my country and plays an important role in ensuring national food security. With the increase of population and the reduction of arable land, fully tapping the potential of corn yield has become one of the fundamental ways to increase corn production. As the main component of the new agricultural management system, agricultural cooperatives play an important role in the agricultural field, and have increasingly become the organizational carrier for promoting large-scale operations in the main grain-producing areas of Northeast China. However, the land under the trusteeship of agricultural cooperatives currently has the problems of non-standard crop production process and land production potential that has not been fully realized. [0003...
