The long acting composite fertilizer consists of nitrogen fertilizer 9-25 wt%, phosphate fertilizer 10-20 wt%, potash fertilizer 8-15 wt%, zeolite 5-20 wt%, weathered coal or turf 5-30, and proper amount of plant ash and plant extracting synergistic water solution. The long acting composite fertilizer has balanced nutrients, lasting action, high utilization and easy absorption, so that it has the functions of increasing yield, raising effect and promoting maturity.

The invention discloses an efficient cultivation method for increasing the yield and starch content of canna edulis. The method comprises steps of land selection, soil preparation, sowing, field management, pest disease and weed control, maturation, harvest, and seed reservation. The method comprises following operation steps: (1) land selection and soil preparation; (2) sowing including variety selection, sowing time selection, potato seed processing, base fertilizer application and planting mode selection; (3) filed management including seedling stage management, intertillage weeding and hilling, top application of fertilizer, water management and florescence management; (4) disease and pest control including disease control and pest control; (5) maturation and harvest; and (6) seed reservation. By employing the method, the canna edulis is high in yield and starch content, and problems that the canna edulis is low in mu yield and starch content are effectively solved. Through the interplanting of canna edulis and soybeans, the growth of weeds can be effectively controlled, soil is loosened, nitrogen is fixed through soybean rhizobium, the application amount of fertilizer can be reduced, green leaves and stems of the harvested soybeans can be returned to the field, the soil productivity can be increased, and finally the income of farmers can be increased.

The invention relates to a use method for a soilless culture box tank for dioscorea opposita. The use method includes the following steps that a, a cultivation medium is prepared and disinfected; b, the box tank, a medium collecting position and a culture box are cleaned; c, the culture box is installed and filled with the medium; d, dioscorea opposita seedlings are transplanted; e, cultivation and management are conducted; f, the dioscorea opposita is harvested. The use method has the technical advantages that the action principle is clear and easy to understand, can be grasped by people of all ages and both sexes, and is not limited by the scientific and technological culture level; the specific soilless cultivation medium is adopted for cultivation of the dioscorea opposita, organic matter in the medium is high in content, nutrients are balanced, the purpose of the high yield of the cultivated dioscorea opposita is achieved, the average per unit yield is 4,162-5,766 kg / 667 m<2>, the adopted medium is disinfected with formalin or manually disinfected in a workshop or replaced in the workshop, and disease and pest damage caused by a cultivation medium for the dioscorea opposita and the negative effects caused by continuous cultivation are avoided.

The invention discloses a cultivation method ensuring field growth time of fen-flavor tobacco leaves and belongs to the technical field of the tobacco plant cultivating technology. The method comprises the working procedures of float breeding, soil preparation, ridging, under-membrane transplanting, membrane covering period management, and field management. A seeding period is from the middle ten days of October to the middle ten days of December. A floating disk float breeding method is adopted. Hardening-seedling is conducted for 8-14 days before transplantation. Soil is broken, and moisture in the soil is stored. Soil is prepared, and a field is irrigated. Ridges are built up with 100-120cm row distances. The height of each ridge is 20-30cm. The width of the bottom of each ridge is 75-95cm. Base fertilizer is added at ridging time in a double-strip mode. A transplanting period is from the middle ten days of January to the last ten days of March. Caves are built up with 45-55cm plant distances. The width of each cave is 10-15cm. The depth of each cave is 15-20cm. 1-2kg root locating water is watered on each plant after transplantation. Land membrane is covered. Fertilize plants additionally for two times after transplantation. Seedlings are induced when tops of tobacco seedlings jack the membrane on the 15th-25th day. The field membrane is uncovered when the tobacco seedlings enter the middle flourishing growth period. Ridging, weeding, watering, tip pruning and branch removing are conducted timely. The method can effectively ensure the field growth time of tobacco leaves, improves the output and the quality of tobaccos, increases the accumulation of aroma substances, and strengthens the fragrance style of fen-flavor tobacco leaves.
