this study examined suitable mechanized methods to seed rice in dry-bed conditions using dried seeds and determined the most suitable varieties for each method. the experimental design was strip-plots in a randomized complete block design with two factors (seeding methods and rice varieties) and three replications. the testing took place during 2003-2004 at the shavour agricultural research sta...

This study is aimed at the special working conditions of seeding on sloping land, combining advanced precision technology and structure rotary hole filling corn metering device seed rowers home abroad, studying soil entry characteristics, characteristics particles transport pattern in puncture process, order to improve dispersal qualified index reduce coefficient variation process seeding. The ...

In present-day mechanized garlic seeding, high missing rates and low qualified percentages of single seeds are common problems; thus, a finger clip plate seed-metering device was designed in this study. First, the structure working principle were studied. Subsequently, critical component parameters determined using theoretical calculations; then, EDEM software used single-factor simulation expe...

Mechanized reasoning uses computers to verify proofs and to help discover new theorems. Computer scientists have applied mechanized reasoning to economic problems but – to date – this work has not yet been properly presented in economics journals. We introduce mechanized reasoning to economists in three ways. First, we introduce mechanized reasoning in general, describing both the techniques an...

This paper designed a centrifugal shellfish seeding device with conical disc structure to improve the efficiency and uniformity of device. The dynamic model seedling moving on disk is established, main parameters affecting seedling’s movement characteristics are determined as cone angle impeller, speed offset blade. Using EDEM software seedlings blanking rate influencing factors, single factor ...
