Abstract
The effects of ground mulching on topsoil water and growth of Jerusalem artichoke were studied under semi-arid rain-fed conditions in northeast China.The experiment used Yulin 6 pickle-type Jerusalem artichoke variety as the test material with three treatments: no-mulching (CK),plastic film mulching(FM) and corn stalk mulching(CS).The results showed that soil water content in the plastic film mulching and corn stalk mulching were respectively 1.7~2.0 and 1.3~2.0 times of that in no-mulching.Both plastic film mulching and corn straw mulching reduced soil pH compared to no-mulching treatments.The cover measure significantly affected plant growth.In the flowering stage,CS had the highest plant height (average for 162 cm) and the stem diameter(average for 18 mm) among the three treatments.Average yield of Jerusalem artichoke tubers in the FM and CS treatments was respectively 9 585 and 11 685 kg·hm-2,increasing by 63% and 99%.Therefore,the ground mulching could improve soil moisture and be beneficial to the high yield and high efficiency cultivation of Jerusalem artichoke in arid region,which it was worth promoting the application.关键词
