Seed field arrangement mode for increasing corn mechanical sowing seedling emergence tidiness rate

Abstract

The invention discloses a seed field arrangement mode for increasing the corn mechanical sowing seedling emergence tidiness rate. Corn planters currently used in China are all monoseeding machines. In order to solve the problem that seedlings are seriously insufficient through a current corn mechanical single-particle accurate sowing mode, the seed arrangement rhythm of a corn planter is adjusted, so that two seeds are sowed in a hole within a line from space to space in the sowing process, and the single-double-particle corn seed plum-blossom-shaped field arrangement mode is formed; under the condition that seedlings are inevitably insufficient in the single-particle field sowing mode, compensation is made in an adjacent-hole double-seedling mode, and group insufficiency is avoided or reduced; through the compensation function between individuals inside corn groups, the yield potential of double seedlings is exerted, yield loss is reduced, and planting benefits of corn are guaranteed.

Description

technical field The invention discloses a seed field layout method for increasing the rate of maize machine-sowed uniform seedlings, relating to the technical field of corn mechanized sowing, and more specifically, a seed field layout method for improving the rate of corn machine-sowed uniform seedlings. Background technique Missed sowing and lack of seedlings in maize mechanized sowing is a serious problem hindering the development of maize production in the Jianghuai region of my country. The corn planters currently used in my country are all single-seed planters, and the uniform single-seed seeding method in the row is adopted when sowing. Because the existing corn seeding machine is difficult to adapt to the unevenness of the farmland in the Jianghuai area, the soil quality is stiff, there are many clods, and the situation of large soil clods, there will be a large number of lack of seedlings or uneven emergence during the sowing process. According to statistics, in the...

Problems solved by technology

In the Jianghuai area where the sowing conditions are unfavorable, people can only adopt some compensatory countermeasures in the face of the inevitable shortage of seedlings in machine sowing

One is to check seedlings to make up for vacancies. This method not only requires a large amount of labor, but also has serious impacts on production.

The second is to double the seeding rate. Although this method can reduce the lack of seedlings and ridges of corn, it is difficult to thin out the seedlings after emergence due to the use of more seeds, more labor, and a decline in economic benefits, so it cannot be popularized.

The third is to use replanting after emergence. Although this method is simple and requires less labor, the size of the seedlings is serious, which eventually leads to a substantial increase in the rate of empty stalks.

The fourth is to carry out seedling cultivation, transplanting and supplementing seedlings. Although this method can effectively solve the technical problem of lack of seedlings in the field, it requires a lot of labor and cannot be popularized.

In order to solve the above problems, agricultural machinery manufacturers have also carried out a lot of research and discussion, but in the end they cannot be solved because of the complexity and difficulty.

In some areas, in order to solve the above problems, they even imported advanced photoelectric sensor corn seeders from abroad, but the effect was not satisfactory in the face of poor sowing conditions.
