Abstract In order to improve the simplified water-saving cultivation technology for Chinese cabbage
〔Brassica campestris L. ssp. pekinensis（Lour）Olsson〕，this paper confirmed the application details of
correlation technique implement．This study observed the effect of adding pesticide on seed germination and
insect pests occurrence at the seedling stage，with different concentrations of phoxim and imidacloprid were
added during the seed encapsulation process separately or simultaneously；investigated the effect of different
seeding rate，different planting patterns on the emergence rate at seedling stage；and surveyed the planting
benefits of different types of Chinese cabbage using precision seeding and simplified planting technology．The
results showed that phoxim（effective ingredient content ≤ 3 g · kg-1）or imidacloprid（effective ingredient
content ≤ 70 g · kg-1）added in the seed encapsulation could reduce the insect pests occurrence at the seedling
stage without affecting seeds germination．The emergence rate of 2 seeds per hole could reach over 88%，and
basically fulfilled the production needs．The emergence rate of drip irrigation was 95%-99%，significantly
higher than that of the traditional furrow irrigation．Compared with the traditional cultivation pattern，
water consumption and labor use were reduced by 10.4%-29.5% and 42.2%-79.0%，respectively by this new
cultivation technology during Chinese cabbage growth period．
