Problems solved by technology

In the existing methods, sparse planting and unreasonable dense planting are the bottlenecks restricting the high yield of corn, especially when corn is tasseling, if the light is insufficient, the corn cobs will be bald, resulting in reduced yield

Embodiment 1

[0024] Example 1: The influence of planting density on yield

[0025] A method for planting corn with wide rows, one hole and two plants, includes the following steps:

[0026] A. Site preparation: Choose a non-saline-alkali block with 30-50% aggregate structure and loose soil as the field, deep till 20-35cm, leveling, and applying basic fertilizer;

[0027] B. Seed selection: sprouting the coated corn seeds until they are exposed, and remove the broken and moldy seeds that cannot germinate. The method for sprouting the coated seeds is: put the coated seeds in the germination container, spray water and stir. , So that all seeds are covered with water and there is no water in the bottom of the container, then spread the seeds flat and the thickness of the seeds does not exceed 10cm, and then soak the sacks in warm water and wring out until no water drips, and finally cover the sacks on the coated seeds, and Spray water once every 3 hours;

[0028] C. Seedling: Sowing the selected seed...

Abstract

The invention provides a wide-row double-tree planting method for planting corn. The method comprises the steps of land preparation, seed section, seedling planting, transplanting, field management, harvesting and the like, wherein the seed selection step comprises the following specific steps of: performing sealed seed pregermination on corn coated seeds until seeds sprout, and removing broken and rotten seeds which are not sprouted; the transplanting step comprises the following specific steps of: when seedlings grow to obtain two leaves and one core or three leaves, transplanting the seedlings to a large farmland, wherein a planting row distance is 90-100cm, the hill spacing is 35-40cm, and two seedlings are planted in one hill. According to the method, the row distance is increased, so that the ventilation condition is greatly improved, the solar energy utilization rate is enhanced, improvement of late-stage yield is promoted, field management is relatively convenient, and labor hours are saved; by use of a one-hill double-tree planting mode, the fertilizer utilization rate is improved, and the fertilizer consumption is saved; by virtue of sealed seed pregermination treatment, waste seeds are effectively removed, and the yield is ensured. The method is low in cost, simple to implement and easy to popularize and apply.

Description

Technical field [0001] The invention relates to the field of corn planting, in particular to a method for planting corn with wide rows and one hole and two plants. Background technique [0002] Conventional corn planting is widely used in equal rows or wide and narrow rows, usually with a row spacing of 66-75cm, plant spacing of 25-35cm, and a density of 2400-3000 plants per mu. For example, the patent publication No. 102138423A discloses a corn planting method in which wide rows and narrow plants and wide and narrow rows are equally densely planted. In the existing methods, sparse planting and unreasonable dense planting are the bottlenecks that restrict the high yield of corn, especially when the corn is tasseled, if the light is insufficient, the corn cob will be bald, resulting in reduced yield. Summary of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a method for planting corn in wide rows and one hole with two plants. [0...
