Design, DEM Simulation, and Field Experiments of a Novel Precision Seeder for Dry Direct-Seeded Rice with Film Mulching

Agriculture, 2021
Existing devices for dry direct-seeded rice with film mulching in northern China have limitations such as imprecise sowing, unadjustable sowing depth, and seeding device blocking.

Progress of Research on Phytohormone Interaction in Germination of Direct-Seeded Rice under Submergence

Agronomy, 2022
Due to rainfall, closed weeding of paddy fields and other reasons, submergence stress often occurs during the germination and emergence stages of direct-seeded rice (Oryza sativa L.), which leads to intensified anaerobic respiration, accelerated ...

Laboratory phenomics predicts field performance and identifies superior indica haplotypes for early seedling vigour in dry direct-seeded rice [PDF]

, 2021
Seedling vigour is an important agronomic trait and is gaining attention in Asian rice (Oryza sativa) as cultivation practices shift from transplanting to forms of direct seeding.

Energy assessment of different rice–wheat rotation systems

Food and Energy Security, 2021
Food and energy security are important issues that threaten human survival and development. The rice–wheat rotation system provides a stable source of food for more than 20% of the world's population, but there have been no reports on the energy balance ...

Effects of Low Light after Heading on the Yield of Direct Seeding Rice and Its Physiological Response Mechanism

Plants, 2023
As a photophilous plant, rice is susceptible to low-light stress during its growth. The Sichuan Basin is a typical low-light rice-producing area. In this study, eight rice varieties with different shade tolerances were studied from 2021 to 2022.

The design of rice direct seeding machine [PDF]

Advances in Engineering Research, 2015
In order to change the existing status of big turning radius of the large direct seeding machines with diesel and gasoline as fuel and improve the low efficiency and time-consuming condition of the machine driven by human or animal, an electric rice planter was designed. The mechanical parts and circuit design had been finished.

Non-puddling rice cultivation increases subsequent soybean yield in a rice–soybean rotation system

Plant Production Science, 2020
Non-puddling rice cultivation would increase subsequent soybean yield. Soybean (cv. ‘Yukihomare’) was grown in farmers’ fields previously cultivated with puddled transplanted rice (Puddled Rice), non-puddled transplanted rice (Non-puddled Rice), and dry ...

Rice Direct Seeding Method with Recycled-paper Mulching [PDF]

Plant Production Science, 1999
We developed a new direct hill seeding method, paper-mulched direct seeding (PMDS). In this method, recycled-paper sheets with rice (Oryza Sativa L.) seeds affixed are spread over a flooded paddy field just after puddling and leveling. Three or five rice seeds were sandwiched between biodegradable gauze or non-woven mesh, fixed to a hole (25 mm ...
