The combined seeder, with its multi-effect integration feature, has emerged as a new powerhouse for boosting efficiency in agricultural production.

I. Introduction: Agricultural Production Efficiency Demands Drive Change

As the process of agricultural modernization accelerates and planting scales continue to expand, the contradiction between tight farming seasons and rising labor costs has become increasingly prominent. Traditional seeders have a single function. To complete multiple tasks such as sowing, fertilizing, and film-covering, different equipment must be used multiple times. This not only consumes time and labor but also increases production costs. The advent of the combined seeder, with its characteristic of multi-effect integration, enables the completion of multiple tasks in a single operation, effectively addressing the pain points of traditional sowing operations and becoming a key piece of equipment for improving efficiency in modern agricultural production.

II. Overview of Combined Seeders

2.1 Definition and Composition

A combined seeder is an agricultural machinery device that integrates multiple operational functions. It is mainly composed of components such as a seed bin, a fertilizer bin, a seed metering system, a fertilizer metering system, a furrow opener, a soil covering device, and a press wheel. Through the coordinated operation of these components, it can simultaneously complete multiple operation steps such as sowing, fertilizing, furrow opening, soil covering, and pressing in a single pass, simplifying the planting process and improving operational efficiency.

2.2 Working Principle

During the operation of a combined seeder, the power system drives the entire machine forward, and the furrow opener first creates seed furrows and fertilizer furrows in the soil. At the same time, the seed metering system accurately dispenses seeds into the seed furrows according to the preset sowing rate and spacing, while the fertilizer metering system applies fertilizer into the fertilizer furrows as per the predetermined fertilization rate. Subsequently, the soil covering device covers the soil over the seeds and fertilizer, and finally, the press wheel compacts the soil to ensure close contact between the seeds and the soil, creating favorable conditions for seed germination. The entire process is carried out seamlessly, achieving efficient collaborative operation of multiple procedures.

III. Core Advantages of Combined Seeders

3.1 Multi-effect Integration for Significant Boost in Operational Efficiency

The combined seeder integrates multiple operations, eliminating the need for repeated multiple operations and significantly shortening the sowing cycle. Compared with traditional sowing methods, it can reduce operational time by more than 50%. Especially in large-scale planting areas, it can complete sowing tasks in the shortest possible time, ensuring that crops are sown on schedule without missing the optimal farming season. Meanwhile, it reduces the number of back-and-forth trips of the equipment in the field, lowering fuel consumption and further saving production costs.

3.2 Precise Operations for Guaranteed Planting Quality

The combined seeder is equipped with precise seed metering and fertilizer metering systems, enabling accurate control of the seed and fertilizer application rates, spacing, and depth. Uniform sowing density and reasonable fertilization amounts are conducive to the growth of crop roots and nutrient absorption, improving the emergence rate and seedling uniformity, and laying a solid foundation for high crop yields in the later growth stages. In addition, accurate furrow opening, soil covering, and pressing operations create a suitable growing environment for the seeds, reducing the occurrence of missing seedlings and broken seedling rows caused by poor sowing quality.

3.3 Cost Reduction for Improved Economic Benefits

From the perspective of equipment investment, the combined seeder replaces multiple single-function devices, reducing equipment purchase costs. During use, it lowers costs in terms of labor, fuel, and equipment maintenance. At the same time, as it ensures planting quality, it increases crop yields and quality, thereby enhancing the market revenue of agricultural products and bringing significant economic benefits to agricultural producers.

3.4 Strong Adaptability to Meet Diverse Needs

The combined seeder can flexibly change its operating mode by adjusting components and parameters according to the planting requirements of different crops. It is suitable for a wide range of crops, including grain crops, cash crops, vegetables, and flowers. In addition, it can adapt to different soil conditions and terrains, operating stably on various plots such as plains and hills, meeting the diverse planting needs of modern agriculture.

IV. Suitable Scenarios for Combined Seeders

4.1 Large-scale Planting of Field Crops

In the large-scale planting of field crops such as corn, wheat, and soybeans, the combined seeder has significant advantages. It can complete multiple tasks such as sowing and fertilizing in a single operation, enabling rapid completion of sowing work on large areas of land and improving planting efficiency.

At the same time, its precise operations ensure uniform crop growth, facilitating subsequent unified field management and mechanized harvesting.

4.2 Cash Crop Planting

For cash crops such as cotton and rape, the combined seeder can accurately control the sowing and fertilization parameters according to their growth characteristics, ensuring good crop growth. For example, in cotton planting, reasonable fertilization and sowing depth contribute to the development of cotton roots and improve cotton yield and quality. In rape planting, uniform sowing density can make full use of land resources and increase per-unit area yield.

4.3 Composite Planting Patterns

In composite planting patterns such as intercropping and relay cropping, the combined seeder can achieve simultaneous sowing and fertilizing of multiple crops by adjusting different seed metering and fertilizer metering channels. This precise operation method can meet the growth needs of different crops, improve land utilization efficiency and per-unit area economic benefits, and promote the popularization and application of composite planting patterns.

V. How to Select and Use Combined Seeders

5.1 Key Points for Selection

Clarify Planting Needs: Choose an appropriate combined seeder model based on your own planted crop types, planting scale, and planting mode. If you plant a single type of crop on a large scale, you can opt for a large and efficient model. If you plant multiple crops or have scattered plots, you need to select a model with more flexible functions and stronger adjustability.

Pay Attention to Equipment Quality: Check the manufacturing process and materials of the combined seeder to ensure that key components such as the seed metering device, fertilizer metering device, and transmission system are of reliable quality, with good wear resistance and stability. At the same time, understand the technical parameters of the equipment, such as the sowing depth adjustment range, seed metering accuracy, and fertilization rate adjustment range, to ensure that they can meet actual planting requirements.

Consider After-sales Service: Give priority to brands and merchants with comprehensive after-sales service. Comprehensive after-sales service can provide timely technical support, equipment maintenance, and spare parts supply, ensuring that problems with the combined seeder during use can be quickly resolved and reducing production delays caused by equipment failures.
