Wide-narrow row corn planter

Abstract

The invention discloses a wide-narrow row corn planter. The wide-narrow row corn planter comprises a rack, a fertilizer hopper, fertilizer furrow openers and seeders; each seeder comprises a seed hopper frame, a seed hopper, a seeding disc, a seed furrow opener, a ground wheel, a ground wheel frame, a ground wheel adjustor and a corresponding power transmission device. The wide-narrow row corn planter is characterized in that at least four seeders are arranged, the transverse distance between the seed furrow openers of the four seeders is distributed in a narrow-wide-narrow mode, and the narrow distance, the wide distance and the narrow distance are formed by the adjacent seed furrow openers; one fertilizer furrow opener is arranged between the two seed furrow openers of each narrow distance in the transverse direction. The wide-narrow row corn planter has the advantages that after seeding, corn seedlings are arranged in narrow rows and wide rows alternately, and plant positions are staggered, rational close planting is achieved, fertilizer is fully used, and tests show that the yield increasing effect is remarkable.

Description

technical field [0001] The present invention relates to agricultural machinery, further to planters, especially for corn. Background technique [0002] For the corn cultivation mode of traditional agriculture in my country, see figure 1 . In the figure: a refers to fertilizer, b refers to corn seedlings, and c refers to field ridges; a row usually consists of 4 rows, and the distance h between rows is about 60 cm. When fertilizing corn seedlings, the fertilizer is usually applied (buried) to the corn Seedling left side or right side (the present invention shows as the right side), apart from corn seedling f1=about 10 centimeters, but like this, fertilizer has about f2=50 centimeters away from the corn seedling of another row. The fertilizer permeates around the center of the fertilization point. Since the fertilizer is far away from the corn seedlings in another row, it cannot be absorbed by the roots of the corn seedlings in another row; thus, on the one hand, the fertili...

AI Technical Summary

Problems solved by technology

The fertilizer permeates around the center of the fertilization point. Since the fertilizer is far away from the corn seedlings in another row, it cannot be absorbed by the roots of the corn seedlings in another row; thus, on the one hand, the fertilizer cannot be completely absorbed by the corn seedlings, resulting in reduce the waste of fertilizer; on the other hand, the fertilizer that is not absorbed can easily form soil compaction and cause a certain degree of soil pollution

[0003] However, it is not easy to find and solve this problem. This is because: 1. The increase of grain production requires a gradual process. During the period of steady growth of grain production, people often neglect to explore the details

2. Due to the continuous improvement of the scientific and technological content of seeds, the yield increases accordingly, and people rely more on seeds to increase yield, thus ignoring the improvement of farming methods

3. People are accustomed to the traditional farming mode, so it is difficult to pay attention to this problem

4. If the distance between corn seedlings and corn seedlings is shortened artificially and simply, there will be a problem of ventilation and light transmission in the later stage of corn crops
