A bunch of red cultivation

Biological characteristics: Herbs are perennial, stems are verticillate, smooth, stem segments often purple, stem base more lignified, up to 90cm, some dwarf plant height is only 20cm-30cm. Leaves opposite, long-handled, leaf-ovate or triangular-ovate, apex acuminate, margin serrate. Crimson flowers, 2 - 6-flowered, densely integrated into terminal racemes, red-fleshed; sepals ovate, dark red, caducous; calyx campanulate, 2-lip, persistent, with corolla color; The corolla lip has a long tube extending outside. The small nuts are oval in shape and have black seeds inside, which are easy to fall off. Flowering July-October; fruit ripening August-October. A string of red and a string of white, a string of purple, a string of powder and other variants, its ornamental value is generally not as good as a string of red. Sex is not cold-tolerant and is often cultivated for one year. Hi sunshine, but also able to resist half shade, avoid frost. The optimum growth temperature is 20Â°C-25Â°C, and it grows slowly below 15Â°C and leaves yellow to fall off; at 30Â°C, the mosaic becomes smaller. Long sunshine is beneficial to a string of red nutrient growth, and short days are conducive to reproductive growth. A lot of red lotus seedlings need more water, avoid drought, when the lack of water, the leaves are easy to wilt, when the leaves are easy to fall off, but afraid of earthworms, when the water is large, the leaves are also easy to fall off, the water will be able to drown in one day. Hi loose fertile bed soil, avoid using heavy earth soil for seedling bed soil. Cultivation techniques: A bunch of red sowing or cutting propagation. Eleventh National Day flowers, sowed in spring March-April, sowing a small amount of base fertilizer into the bed, leveling the bed and irrigating the water, soaking after the water sowing, about 1cm cover fine soil, often spray water to keep the bed Wet surface, 8 days to 10 days seed germination. When the cotyledons of the seedlings are expanded, they can be transplanted, and they can be planted with soil after one month. Before planting, it is necessary to pick up the heart so as to reduce the evaporation of water and promote the emergence of new shoots. When the lateral branches give birth to three to four leaves, they can be picked again and picked several times to increase branching, enlarge the crown, and increase flower spikes. If Mayflower is used, it can be broadcast in open field in the middle and late August. In the middle of October, it will be planted in the greenhouse. After more than 10 days, the roots will grow. In the middle and late November, the pots can be gradually raised and cultivated in the greenhouse. A string of red cuttings is easy to reproduce, rooting can be done 10 days to 20 days after cutting, and 30 days can be planted. The flowering of the cutting seedlings is earlier than the seedlings propagated with seeds, and the height of the plants is also easy to control. Cutting sand with river sand. Origin of cuttings: In the fall, a bunch of red plants are moved into the greenhouse for winter, and fresh branch cuttings are cut in the early spring. The ground temperature is controlled at about 20Â°C, and the rooting is easy. In winter, the seedlings are grown after the seedlings are grown, and then the cuttings are continued. Cutting seedlings must be picked up after many times to bloom. It takes about 130 days from cuttings to flowering. The flowering date can be extended by picking the heart. The main disease during the seedling stage is damping-off. The main insect pests are whitefly, aphids, and red spiders.
