Abstract:

Effects of waterlogging tolerance at the full flowering stage of the sesame in differences planting patterns. The sesame in ridge planting and flat planting patterns were treated by waterlogging at full flowering stage (after 28 days of early flowering), and surveyed area of wilting plant, rate of wilting plant, degree of disease occurrence and other indicators of the sesame in two planting patterns after the sprinkler of water, determined dry matter accumulation of sesame at the different stages, tested species and determined yield indoor in maturity stage, calculated input-output ratio, compared economic benefit. The results showed that ridge planting pattern were effective better than flat planting pattern at the occurring of sesame wilting, lodging, leaf spot, stem blight; waterlogging at full flowering stage were inhibition to sesame in two planting patterns, but was letter to ridge planting sesame, waterlogging significant impacted the agronomic traits and yield of the sesame in two planting patterns, and the impact of the sesame in flat planting pattern was greater than the sesame in ridge planting pattern, which, Significance test showed that the differences were capsules per plant > yield per plant > yield > length of capsule axis > capsule nodes per plant > height per plant, and significant test was highly significant, the difference of length per capsule was significant, the differences of seeds per capsule and 1000 seeds weight were not significant. Input-output ratio of ridge planting sesame and flat planting sesame were 1:2.86 and1:2.04, ridge planting sesame increased in net income per hectare was 5 492.7 yuan.
