Embodiment 1

[0017] Embodiment 1 The present invention is used for the single hole double planting of corn. Sowing is carried out around April 20th to May 1st in North my country. Before sowing, the seeds are first manually screened, and the sown corn seeds are required to be neat and uniform in size. And treat with plasma space machine 5-12 days in advance, and carry out seed coating disease prevention treatment, then use drought-resistant seed coating agent to dress corn seeds, dry in the shade and sow.

[0018] Apply 20-25kg of urea, 25-30kg of diammonium phosphate, and 15-20kg of potassium sulfate to the sowing land per mu.

[0019] Corn planting is carried out according to the equal ridge spacing, the ridge spacing is about 60cm, and the two plants are planted in one hole according to the plant spacing of 50-65cm, that is, 2 seeds are planted in each hole, and the distance between the two seeds in the same hole is 5-10 cm. The seeds are distributed perpendicular to the direction of ...

Embodiment 2

[0022] Before sowing in Example 2, the corn seeds were first screened, and the sown corn seeds were required to be neat and uniform in size. It is best to select two adjacent seeds on the same cob, or take the seeds in the middle part of the seed ear, and select them to achieve the same growth and character, and treat them with a plasma space machine 5-12 days in advance, and carry out seed packaging Clothing and disease prevention treatment, and then use the drought-resistant seed coating agent to dress the corn seeds, dry them and sow them.

[0023] Corn planting is carried out according to equal ridge spacing, the ridge spacing is about 65cm, and sowing is carried out in the form of two consecutive holes with double plants and one hole after planting. The plant spacing between the two holes is 60-70cm. When sowing, ensure that each hole has at least two seeds, and use about 1 kilogram of corn seeds per mu.

[0024] When the corn seedlings grow to 3-4 true leaves, carry ou...

Abstract

The invention relates to a high-yielding planting method for yellow maize. The method is characterized in that during maize planting, one-pit double-plant planting is carried out among maize of different growing periods in a manner that equal ridging spacing is adopted, the planting distance between every two continuous pits is 3,055cm, and the planting distance between corresponding two continuous pits and another two continuous pits is 60-75cm. According to the high-yielding planting method for the yellow maize, the method can be in line with the habit of growth of the maize and adapt to the growth characteristic of the maize, the requirements of a whole growth process on ventilation and light transmission can be met, the number of maize plants planted is increased in case of lowering the planting density of the maize, and the aims of saving fertilizers and increasing yield are achieved by using principles such as biodiversity.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield planting method of yellow corn. Background technique [0002] Corn is the main crop in my country, and corn production is an important industry in my country. For increasing agricultural production, increasing farmers' income is very important. In order to increase corn yield and change the traditional corn planting method, people increase the yield of corn through intensive cultivation and increasing the planting density of corn per plant. This method will reduce the sunlight and ventilation of corn. performance, resulting in negligible increases in corn yields. [0003] In the prior art, wide and narrow rows are adopted to reduce the adverse effects on ventilation and light transmission while increasing the number of corn plants by reducing the distance between plants. Because this method has changed the traditional farming methods of fa...
