The results showed that： dry mass per plant and leaf area per plant of formula 3 were higher than Jiangxi cotton seedling nurs- ery substrate.the higher proportion were 48.4% and 73.5%; the rate of forming plantlets, survival rate of transplant and the unginned cotton yield had no obvious difference with the other matrix seedling and transplanting; nursery substrate was returned using as fertilizer, reduced environment pollution, achieved comprehensive utilization and cyclic utilization. Cotton seed hulls after the production of edible fungi residue was a cotton seedling substrate material of saving work,reducing cost and protecting environment and would have a good application prospect.展开更多

[Method] A seedling-raising orthogonal test was carried out on green cabbage under different irrigation upper limits and different substrate nutrient levels. [Result] Proper irrigation could promote leaf expansion, while excessive irrigation wa- ter inhibited leaf expansion; fertilization inhibited leaf expansion; and water and fertil- izing coupling showed a superimposed effect on leaf expansion. Proper irrigation promoted stem and root growth; fertilization inhibited stem and root growth; and there was a very strong water and fertilizer interaction effect. Under more irrigation water and proper fertilizing amount, root growth was promoted, stem elongation was inhibited, material accumulation of plants was increased, and sound seedling index was improved. [Conclusion] Water and fertilizer coupling effect could be used for regulating growth and development of various organs of green cabbage and improv- ing seedling-raising efficiency and quality.展开更多
