Review of precision rice hill-drop drilling technology and machine for paddy

Abstract

Mechanized rice direct seeding is a cost-effective and efficient approach for rice cultivation. Recently, the use of rice direct seeding has been increasing rapidly owing to rural labour shortages and continuous increases in agricultural production costs. This article reviews the research and application progress of mechanized rice direct seeding including direct seeding technologies, precision rice seeding, precision rice seed-metering devices, key supporting agronomy technologies for mechanized rice direct seeding. South China Agricultural University developed precision rice hill-drop drilling (PRHDD) with synchronous furrowing and ridging technology and series machines for paddy that affords remarkable advantages in terms of saving time and labour, higher yield, and higher efficiency. In this approach, pre-germinated seeds are uniformly hill-dropped in the expected positions in puddled soil. It significantly improved the crop growth population and effectively solved the problems of high frequency of disease and pests caused by the irregular distribution of rice seeds with manual broadcasting, and generally reduces seed usage and increases the yield. Therefore, this technology has broad application prospects and great potential for promoting the development of mechanized rice direct seeding in China.

Pengaruh Penggunaan Traktor Terhadap Pendapatan dan Penggunaan Tenaga Kerja pada Usahatani Padi di Kabupaten Sambas

“…Selain itu penggunaan traktor telah dapat menghemat penggunaan tenaga kerja yang dapat mempercepat kegiatan persiapan lahan, karena ketersediaan tenaga kerja yang semakin berkurang dan petani dapat melakukan penanaman tepat waktu pada musim tanam. Penerapan mekanisasi pertanian dalam jangka panjang akan mempengaruhi permintaan tenaga kerja manusia, meningkatkan efisiensi tenaga kerja manusia, serta meningkatkan kuantitas dan kualitas hasil produksi pertanian (Zhang, et al, 2018), (Fulin, Shengxue, & Xiaoming, 2016), (Yinggang, et al, 2013).…”

Sowing uniformity of bed-type pneumatic maize planter at various seedbed preparation levels and machine travel speeds

“…This precision seeding system may either be mechanical or pneumatic. Seed spacing uniformity is an important indicator in evaluating seed drill performance because a uniform distribution of seeds can not only provide maximum space for each plant but also make for uniform root size, which can increase yields and reduce harvest loss [4,5] . Thus, productivity depends on the spatial distribution of plants in the crop field.…”

“…Various studies were conducted to design and evaluate the performance of the pneumatic planting system [4][5][6][11][12][13][14][15][16][17][18] . Yang et al [3] reviewed the research progress and development of precision maize planters and concluded that the usage, modification and improvement in the pneumatic planter depended upon the geophysical and climatic crop requirements.…”

Magnetic field distribution simulation and performance experiment of a magnetic seed-metering device based on the combined magnetic system

“…Studies reported that the mechanical, pneumatic and magnetic seed-metering devices are the most common apparatuses for plug tray seeding [4][5][6] . As for a mechanical seed-metering device, seeds' filling, holding and discharging processes are completed by the seeds' gravity and mechanical device [7][8][9] .…”
