Problems solved by technology

At present, almost all corn in Heilongjiang Province is continuously cropped. Obstacles to continuous cropping of corn cause an imbalance of soil nutrients and surface water resources, and damage to the soil structure, which is not conducive to the sustainable reproduction of corn.
In order to increase the yield of corn, a large amount of chemical fertilizers are applied to the soil in the process of planting corn, which will cause soil acidification, environmental pollution, damage the soil structure and make the soil harden, and even lose the value of agricultural cultivation

Embodiment 1

[0030] The technical steps of simultaneous two-to-two hole sowing and supporting planting technology for corn planting and raising are as follows:

[0031] 1. Land preparation and ridging: Clean up the straw, weeds and sundries on the soil surface, and use a rotary tiller with a rotary tillage width of 130cm to carry out rotary tillage with a distance of 65cm;

[0032] Two, hole sowing and fertilization: adopt the two-to-two empty planting method, that is, plant two ridges and two empty ridges; use a corn hole seeder with a model of 2BY-2 to carry out hole sowing, and the corn seeds are sparsely planted large ear corn varieties, and each hole is sown with two plants. The average distance between two adjacent holes on the same sowing ridge is 30-33cm. When sowing, the points on the two rows of sowing ridges correspond in parallel and synchronously, and sow 3000-3300 plants per mu;

[0033] The corn seeder with the model 2BY-2 is used to apply the fertilizer at one time during t...

Embodiment 2

[0039] The steps of simultaneous three-to-three hole sowing and supporting planting methods for corn planting and land raising are as follows:

[0040] 1. Land preparation and ridging: Clean up the straw, weeds and sundries on the soil surface, and use a rotary tiller with a rotary tillage width of 130cm to carry out rotary tillage with a distance of 65cm;

[0041] 2. Hole sowing and fertilization: adopt the three-to-three-empty planting method, that is, plant three ridges and three ridges in the air; adopt a corn hole sower with a model of 2BY-2 to carry out hole sowing, and the corn seeds are sparsely planted large ear corn varieties, and two plants are sown in each hole. The average distance between two adjacent holes on the same sowing ridge is 33cm, and the points on the 3 rows of sowing ridges correspond to each other in parallel and synchronously when sowing, and 3000 plants are sown per mu;

[0042] The 3-row corn seeding machine that adopts model is 2BY-2 and fertiliz...

Embodiment 3

[0048] The steps of simultaneous four-to-four hole sowing and supporting planting methods for corn planting and land raising are as follows:

[0049] 1. Land preparation and ridging: Clean up the straw, weeds and sundries on the soil surface, and use a rotary tiller with a rotary tillage width of 130cm to carry out rotary tillage with a distance of 65cm;

[0050] 2. Hole sowing and fertilization: adopt the four-to-four-empty planting method, that is, plant four ridges and four ridges in the empty four ridges; use a corn hole seeder with a model of 2BY-2 to carry out hole sowing, and the corn seeds are sparsely planted large ear corn varieties, and two plants are sown in each hole. The average distance between two adjacent holes on the same sowing ridge is 33cm, and the points on the two rows of sowing ridges correspond to each other in parallel and synchronously during sowing, and 3000 plants are sown per mu;

Abstract

The invention belongs to the technical field of corn planting and particularly relates to corn planting and land improvement synchronous equal ratio empty cave bunch planting and supporting cultivation. The planting method comprises the following steps of land preparing and ridging, equal ratio empty cave bunch planting and fertilization, harvesting, stalk application and one-year fallow land improving, transferring rotted stalk into an organic fertilizer, and crop rotation planting. The equal ratio empty cave bunch planting method is adopted, corns can be well ventilated with light transmitting in both transverse and vertical directions, therefore, during the growth of corns, light energy absorption and light energy utilization and transformation in high photosynthetic efficiency can be achieved, increases of the corncob row number, the row niblet number and the thousand kernel weight are promoted, the formation of large corncobs is promoted, the lodging resistance of the corns is enhanced, the water content of the corns drops by 2-5%, and the yield increase range of the corns can reach 5-20%. According to the equal ratio empty cave bunch cultivation, 50% of a land can be fallowedand improved, fertilization and land fertility are achieved, the soil is loosened, surface water is preserved, and 40-50% of fertilizer usage amount is reduced. The corns can be planted organically and efficiently in a green and low-carbon mode.

Description

technical field [0001] The invention belongs to the technical field of corn planting, and in particular relates to synchronous hole sowing and matching cultivation of corn planting and raising land. Background technique [0002] Corn is the main crop planted in Heilongjiang Province. In 2016, the sown area of ​​corn in the province reached 70 million mu, and the sown area of ​​corn accounted for 48% of the sown area in Heilongjiang Province. The development of corn production in Heilongjiang Province is closely related to the innovation of corn planting technology. At present, corn planting mostly adopts the traditional single planting mode of small ridges. In order to increase the yield of corn, it is often necessary to increase the planting density. However, high-density planting in large areas will lead to severe shading, poor lighting, poor ventilation, and reduced photosynthetic efficiency. The growth and seed setting of corn are poor; in addition, the excessive planti...
