The purpose of the invention can be realized by the following technical scheme: a sowing and cultivating method of zinnia involves selecting a plot with fertile soil, flat terrain, superior geological conditions and less land pollution; after land is finished, base fertilizer is applied, a single double-layer heat-preservation greenhouse is built, a special film is covered above the greenhouse, and a sunshade net is covered outside the greenhouse. The small arched shed is built by building a brick cuttage bed along the direction of the greenhouse, a layer of clean fine sand is laid at the bottom of the small arched shed, and cuttage matrixes prepared in advance are laid on the fine sand. And carrying out sealed fumigation by using a sulfur fumigator every day, wherein the fumigation can be carried out for 1 time every 5-7 days as prevention, generally for 1.0-1.5 hours at night, after the fumigation is finished, the greenhouse is kept sealed for more than 5 hours, and ventilation is carried out to keep the sterilization effectiveness. Preparing a mixture matrix by using leaf mold, garden soil, river sand soil and perlite according to the proportion of 4: 3: 2, and disinfecting by using 0.05 percent potassium permanganate or 1000 times of agricultural formaldehyde solution; the method is characterized in that excellent zinnia elegans seeds are selected for seedling tray seeding, reasonable planting density is determined during seeding, the density is controlled to be most suitable when leaf tips touch each other before transplanting of the seedlings after germination, the seedlings are not easy to be squeezed or dredged, the thickness of covering soil is suitable for preventing the seeds from being seen, the seeds are lightly compacted after seeding, and the seeds are enabled to be tightly combined with media. Transplanting the seedlings in the 2-leaf 1-heart stage, preferably transplanting in the shade or in the evening after the noon, carefully taking the seedlings to avoid damaging roots, watering the seedlings after transplanting, and shading for 4-5 days to promote survival. After the seedlings survived, the seedlings gradually exposed to light. In the growth period, 0.2% urea can be properly applied to promote the vegetative growth. The culture soil for field planting can be prepared according to 3 parts of garden soil, 2 parts of leaf mold and 1 part of sandy soil, and is disinfected, the seedlings are directly potted when growing to 3-4 pairs of true leaves, a nutrition pot of 12 cm multiplied by 13 cm is generally adopted for potting, the pots can be put in place at one time, the pots do not need to be changed, and the seedlings can be placed in a warm sunny or direct-sunlight field and are properly picked after potting; in the reproductive growth stage, especially in the bud stage, fertilizer can be additionally applied.
