Planting technology of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma was studied on the base of other studies, the experiment adopted with the combination design of orthogonal and quadratic regression equation. The affection of three factor (nitrogen, phosphorus, potassium) and five levels on the yield of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma were studied, different transplanting and plucking flower period was experiment with based on the design of two factor, gtowlh, yield, aid appearance quality of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma were studied on different transplanting and plucking flower period, single leaf area and branching number were investigated in closure stage, the content of chlorophyll was determined in different growth period, the length of root tuber and the course of root tuber expansion were measured in root tuber expansion stage, dry matter percentage, dry weight of single root tuber, 100-seed weight and appearance quality were determined in harvest period. The results were as followed1 environmental quality of atmosphere, amount of heavy metal and pesticide of soil, the quality of irrigating water was determined in the experiment field, the organic matter, amount of heavy metal and pesticide of soil and water quality have not exceeded the national current relevant standard, environmental quality of atmosphere was very well, the area was regard as GAP field of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma2 the measure of high yield of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma was thatN: 30.6972-32.7076kg/666.7m2, P2O5: 17.7222-20.3911kg/666.7m2, k2O: 46.8335-49.9901 kg/666.7m2.3 effect of different transplanting period to yield have extremely remarkable difference, the yield which was transplanting was the highest on 25th March in this experiment, the yield decreased gradually with postponement of transplanting, mathematics model of yield and transplanting was significant curve correlation, number of leaf, single leaf area, branch number, root tuber number, activity of root was extremely remarkable difference in different transplanting period, 100-seed weight and appearance quality was not significant in different transplanting period.4 leaf number, single leaf area, content of chlorophyll, activity of root and yield of LiriopeSpicata(Thumb)Lour. Var. ProliferaY. T. ma was extremely significant liner correlation in root tubers emerges. Single leaf area, activity of root and fresh and dry weight were extremely remarkable. Leaf number, content of chlorophyll and yield was extremely significant.5 leaf number, branching number and activity of root were increased remarkably when flowers was plucked in bonnets period, root tuber number, fresh and dry weight of root tuber was increased, leaf number, content of chlorophyll and yield was not significant.6 root tubers of LiriopeSpicata (Thumb) Lour. Var. ProliferaY. T. ma emerged in September, fast expanding period was from the beginning of November to December and the beginning of February to March in the next year, volume of root tuber expanding reaches ripple after march, diameters expand was a little faster than length expand in this experiment,(in the first month of expanding ,The diameter reaches 73.89% of the final diameter. The length reaches 71.44% of the final length.)7 amount of dry matter accumulation was not different in different transplanting period. Amount of dry matter accumulation of early transplanting was larger than that of early transplanting, amount of dry matter accumulation of plucking flowers was higher than that of non-plucking flowers. T/R of early transplanting and plucking flowers were higher than that of late transplanting and non- plucking flowers, it showed that amount ofdry matter accumulation of early transplanting and plucking flowers was higher.8 the yield was firstly determined by root tubers number, the yield was increased with enhancing of branching number in the yield constituent factor, effect of 100-seed weight on...
