Description

Corn subsoiling full-layer fertilization precision seeder

technical field

The present invention relates to a planter among agricultural machines.

Background technique

According to the law of nutrient absorption during the growth period of corn, the principle of fertilization for corn is: apply enough base fertilizer, lightly apply seedling fertilizer, re-apply joint fertilizer and bract fertilizer, and apply granular fertilizer skillfully. As the amount of chemical fertilizers increases, the issue of economical and rational fertilization or high-quality, high-yield and efficient fertilization becomes more important. Insufficient fertilization will directly affect the yield of crops. Excessive fertilization will not only cause economic waste, but also affect the quality of products, and even cause environmental pollution and ecological disasters. Experiments have proved that on the basis of actively fertilizing the soil and increasing the soil organic matter and nitrogen content in agricultural production, timely topdressing a certain amount of available nitrogen fertilizer can make the corn yield stable and high, but at the same time it will inevitably increase the labor force input. With the development of agricultural production, the degree of agricultural mechanization is also increasing accordingly, and agricultural fertilization machinery is an inevitable way out for agricultural fertilization. The current corn fertilizing seeder generally applies fertilizer to a certain depth once during the sowing process, which cannot guarantee that there is sufficient fertilizer in the soil layer during the whole process of corn growth. Therefore, it is of great significance to design a corn subsoiling full-layer fertilization precision seeder to improve seeding quality and plant yield.

Subsoiling and full-layer fertilization refers to the one-time application of chemical fertilizers into the soil according to agronomic requirements to meet the nutritional needs of each stage of corn growth and development. At the same time, deep fertilization can play a role in subsoiling, breaking the plow bottom layer, and benefiting the growth of crop roots. One-time full-layer fertilization breaks the traditional farming procedures, saves excessive labor input, improves the utilization rate of fertilizers, and achieves the purpose of increasing grain production and farmers' income.

Contents of the invention

In order to ensure that there is sufficient amount of fertilizer in soil layers of different depths during the corn growth process, reduce the labor force added in the topdressing process, and improve labor efficiency, the invention provides a corn subsoiling full-layer fertilization precision seeder. The device can deeply apply the fertilizer under the surface, and a certain amount of fertilizer will be applied to different soil layers below the sowing depth. To ensure that the corn has sufficient fertilizer supply throughout the growth process. The device consists of a girder, a cutting disc bracket, a cutting disc, a full-layer fertilization ditching shovel, a front side soil covering wheel, a disc ditch opener, a rear side soil covering wheel, a pressing wheel, a seed meter, a four-bar linkage mechanism, a seed box and Fertilizer box composition.

The technical solution adopted by the wooden invention to solve its technical problems is: to open several holes at different heights on the baffle plate behind the full-layer fertilization ditching shovel; there is a baffle plate under each hole, which is convenient for receiving fertilizer and distributing it. Discharging; a covering wheel is installed between the full-layer fertilization ditching shovel and the disk opener; the full-layer fertilization ditching shovel and the disc opener under the seeder are staggered left and right by 5 cm; A cutting disc is added in front of the ditch to reduce the resistance of the soil and straw to the ditching shovel.

The beneficial effect of the invention is that the fertilizer is deeply applied to different depths in the soil, the utilization rate of the fertilizer is improved, sufficient fertilizer is ensured in every process of corn growth, labor input is reduced, and yield is increased.
