Melon chrysanthemum blossoms from winter to early summer. Plant height 30 to 60 cm, generally takes 8 months from sowing to flowering. If you want to make it "May 1" bloom, the usual is to plant in August. Over the past few years, we have been experimenting and sowing seeds in the mid-to-late October. After technical processing, we can also flower in May 1st, and we will spend 185 days in the whole period of growth. This will save management time. Let us try.
First, sowing
Seedlings were planted in late mid-October. The seedlings were transplanted into shallow basins in mid-November with a spacing of 4*5 cm. In late January, the youngest seedlings will be topped with pots and pots, cultivated with garden soil, sand, and decomposed chicken manure in a ratio of 4:3:3. After putting the pots into the middle temperature greenhouse, the night temperature should not be lower than 8°C, the daytime temperature should be kept at 23°C to 25°C, the relative humidity should be 85% to 90%, and when six or seven leaves grow, they can be moved into the low temperature greenhouse. Seedlings.
Second, management
When the seedlings grow four or five leaves, they are planted into pots 15 to 20 cm in diameter. One week later, a 200-fold dilution of bean cake was used to apply water, applied every 7 to 10 days, once a month, 5 days, until one week before flowering. In order to make the flower colorful, small seedlings can be used for the "leaf face treasure" and potassium dihydrogen phosphate spray foliar. In order to inhibit shoots and leaves, 15% of wettable paclobutrazol powder 1000 times can be sprayed once every 20 days. After bud emergence, the plants can be dwarfed and stout, and the flowering period is neat and consistent.
Third, pest control
Cineraria is susceptible to powdery mildew and leafminer during its growth in the greenhouse. To control powdery mildew, except for removing diseased leaves, spray 25% carbendazim or 50% thiophanate 500 to 800 times and 20% triadimefon 3000 times. Leaf miners can be sprayed with 2.5% deltamethrin for 2000 times with good results.
