Abstract:
The cucumber secondary salinized soil in Fangshan solar greenhouse was used as the test soil,and the effects of soil conditioner (750,1 500,2 250 kg?hm-2) under mild salt stress were applied with organic fertilizer and microbial fertilizer,in order to improve soil fertility and cucumber growth and development.The results showed that after applying soil conditioner and microbial fertilizer,the content of soil organic carbon and available nutrients increased,and soil fertility improved.Cucumber plant height,stem diameter,number of leaves relative content of chlorophyll increased significantly,malondialdehyde content decreased,proline content increased significantly,with a maximum increase of 24.1%.Soil conditioning agent and microbial fertilizer combined had a better effect on alleviating salt stress on cucumber.The content of total nitrogen,total potassium,calcium,iron,manganese,zinc and boron in cucumber stem and leaf organs were significantly increased.The content of vitamin C,soluble solid and cucumber yield in cucumber were increased by 22.4%,12.6% and 36.8% respectively compared with CK in the control group,which significantly increased the quality and yield of cucumber.Soil conditioner showed significant effects in improving the fertility of secondary salinized soil,reducing salt stress,promoting the growth and development of cucumber plants and increasing the yield and quality of cucumber plants.
