Forget-Me-Nots is a genus of forget-me-nots in the family of purple grass. Forget-Me-Nots originated in Eurasia. Leaves are alternate, narrowly oblanded or striate oblateolate. Forget-Me-Nots flowers are small and beautiful, with a yellow core in the center of the blue flower. The color matching is harmonious and eye-catching. The cymbals gradually elongate with the opening of the flowers, half containing and half dew, making them attractive and memorable.
Forget-Me-Nots is a perennial herb. Stems are erect, single or several fascicled, 20 -- 45 cm tall, usually branched, sparsely spreading hispid, sometimes curly. Basal leaves and lower stem leaves are stalked, narrowly oblanceolate, oblong-lanceolate or linear-lanceolate, 8 cm long and 5-12 mm wide, apex rounded or slightly acute, base tapering, lower wing, strigose on both surfaces, base of hair with small basal discs; Stem is above middle leaves sessile, shorter and narrow. Inflorescences are short, elongate to 15 cm long after anthesis, bracteate; Pedicels are coarser, erect in fruit, 4-6 mm long, as long as or slightly longer than calyx, densely short hairy; Calyx is 1.5 -- 2.5 mm long, fruitally enlarged, 4 -- 5 mm long, lobes 2/3 -- 3/4 of calyx length, lobes lanceolate, apically acuminate, densely covered with extended or hooked hairs; Corolla is blue, 6-8 mm in diam., tube ca. 2.5 mm long, lobes 5, suborbicular, ca. 3.5 mm long, laryngeal appendages 5, ca. 0.5 mm high; Forget-Me-Nots anthers are elliptic, apex with rounded appendage. Nutlets are ovate, ca. 2 mm long and 1 mm wide, dark brown, smooth, shiny, narrowly marginal around but apically conspicuous, base without appendages.
Forget-Me-Nots has strong adaptability, likes dry and cool climate, avoids heat and humidity, likes light, and is resistant to drought. The suitable temperature for growth is 20℃-25℃. It is suitable for growing in loose, fertile and well-drained alkaline soil.
Forget-me-not distributed in Europe, Iran, Russia, Pakistan, Kashmir, India, and China's jiangsu province, northwest, north, northeast, sichuan, yunnan and other places, growing within 200 meters to 4200 meters, more than in broad-leaved forest margins, hillsides, forests and grass valley, yet by artificial cultivation.
Forget-Me-Nots uses two methods: sowing propagation and tissue culture. Sowing is generally from September 1 to January of the next year, the seeds have light, the seeds after sowing to slightly add soil, maintain humidity. Germinated for 10 ~ 15 days under the optimum temperature of 15- 20℃. Sowing should pay attention to the temperature and should not exceed 25℃, the germination unearthed after ventilation, seedlings with more than 5 pieces of true leaves when planting. Tissue culture seedlings were planted with 4 ~ 6 leaves.
Forget-Me-Nots likes dry soil, deep soil layer, loose and breathable, slightly alkaline sandy loam, such as decomposable organic fertilizer and slow-acting compound fertilizer, which are evenly poured into the soil after application. The row spacing of plants should be 30 cm ×40 cm, and the planting depth should be slightly higher than the root neck. After planting, the temperature should be kept below 15℃ for 2 months to facilitate the plants to pass the vernalization stage and facilitate the normal growth and flowering.
Forget-Me-Nots does not require much soil, but loose and breathable sandy loam with a deep soil layer is preferred. Before colonization, adjust the pH of the soil to make it slightly alkaline. The amount of basic fertilizer accounts for 70% of the total amount of fertilizer. According to 2 planting beds per 100 meters, it should contain 1.75kg of nitrogen, 2.0kg of phosphorus, 2.1kg of potassium and 0.14kg of boron. The base fertilizer should be slow - acting compound fertilizer and manure organic fertilizer, which should be evenly turned into the soil after application. Leveling to do the bed, bed high about 20cm. Plantlet row spacing is 30 cm ×40 cm, double row staggered. If planting Forget-Me-Nots 3 lines, the 3 lines staggered, conducive to ventilation and light. Seedling planting should not be too deep, planting depth to root and soil surface flush is appropriate, after transplanting timely pouring permeable.
In the growing period, 70% of the total amount of fertilizer, such as nitrogen and potassium, was applied as the base fertilizer, 30% as the top dressing, and all the phosphorus was applied as the base fertilizer, and the top dressing was usually applied once a season. Potassium fertilizer and boron fertilizer can improve the quality and yield of cut flowers.
Forget-Me-Nots prefers dry and well-drained environments and avoids waterlogging. Watering should be properly controlled throughout the growth period, otherwise flowering quality and yield will be reduced.
When the seedlings began to grow alive, every 10 days with irrigation for topdressing, in the water to supplement 200 mg/kg of nitrogen fertilizer, 100 mg/kg of potash mixture for fertilization. Keep the soil moist during the seedling period of Forget-Me-Nots, pay attention to often plow weeding, promote the robust development of the root system of the seedling. About 2 months after the seedling planting, begin to pull out the flowering branches. Into the flowering period of Forget-Me-Nots, water and fertilizer to be sufficient, otherwise short flowers, flowers are not luxuriant. Nitrogen and potassium mixture of 200mg/kg can be added to irrigation water and applied every 10 days or so.In order to improve the yield and quality of the cut flowers of A. Forget-Me-Nots, in addition to topdressing liquid fertilizer, the mixture of 0.1% potassium dihydrogen phosphate and O. 01% boric acid should also be used for foliar spraying.
Forget-Me-Nots likes sunshine and avoids high temperature and humidity. It takes 1.5 to 2 months for Flower bud differentiation, and the temperature is below 15℃. Long sunshine conditions are favorable for flower formation, while temperature higher than 30℃ or lower than 5℃ is unfavorable for its growth. Therefore, when the forget-me-nots planted in spring and summer are not treated with low temperature, the time of entering the greenhouse should be delayed to make them fully accept low temperature and complete the vernalization.
Forget-Me-Nots prefers a cool environment and is afraid of hot weather. It is best to control the ambient temperature at 12 ~ 20℃ in the cultivated species. Forget-me-nots plants have strong cold resistance. Under the natural temperature conditions of Kunming in winter, some varieties can overwinter on the ground. Most varieties will bud and blossom in the next spring as long as their roots have fully grown before winter, even if all the above-ground leaves are dead. However, Forget-me-nots flowering is very sensitive to low temperature. Only when the daytime temperature is above 20°C and the night temperature is not lower than 10℃, can flower branches grow and blossom.
Forget-me-nots must be exposed to sufficient sunlight to grow properly. If the environment is shaded, the plexus is lush, but the flower-scapes are few. Therefore, the plants should receive more than 4 hours of sunlight per day. Growth is better if full sunshine can be guaranteed.
In order to produce high-quality forget-me-nots cut flowers, it is usually necessary to pull a net to fix the Forget-Me-Nots branches. The specific practice is to use a nylon net of 25 cm ×25 cm or 30 cm ×30 cm, 20 ~ 30 cm from the ground to pull a layer of net frame before the plant is moss plucked.
To produce high-quality forget-me-nots cut flowers, a net is usually drawn to secure the branches. Specific approach is to be in the plant before taking out moss, be apart from the ground 20 ~ 30 cm pull a net frame, wait for the plant to grow after flower-scape, again be apart from the ground 45 cm high place cover on the second layer of net. As the flowers grow, lead the flowers into the grid and keep the stalk upright.
Forget-Me-Nots should be treated differently during growth according to the size of the seedling. For the larger plants with basically closed leaves between Forget-Me-Nots, each Forget-Me-Nots should keep 4 to 5 flower branches for their growth and flowering. For smaller Forget-Me-Nots, the flowering branches can be removed to inhibit their temporary non-flowering, so that their plants can fully grow, and lay a foundation for the production of high-quality cut flowers. When Forget-Me-Nots are fully grown, they can enter the flowering period. During this period, it is necessary to regularly remove the newly extracted delicate branches to concentrate the nutrient supply of flowering branches, and improve the ventilation and light transmission conditions inside the plant, reduce the number of blind flowers in the lower part of the plant, and improve the quality of single flower branches. After cutting more than 50% of the flowers, we should start to cultivate the next crop of flowering branches. The practice is to retain a small number of fresh flowers in this period, after the last stubble cut all the flowers, the reserved flowers have grown to a certain height, so as to effectively shorten the time between the two stubble flowers, so that the love grass can continue to bloom and supply the market.
The diseases of forget-me-nots include gray mould, powdery mildew, viral disease and so on.
We can use 800 ~ 1000 chlorothalonil, methyl tobutin continuous spraying 3 ~ 4 times control. Powdery mildew can be used powder xiuning spraying prevention and control, virus diseases mainly take timely removal of the infected strains burned, spraying insecticide to prevent insect transmission of disease and other measures to control.
It is the most common insect pest of turtleback bamboo. It can be cleaned with a small amount of old toothbrush and sprayed with 40% oxidized dimethoate emulsion 1000 times liquid.
Forget-Me-Nots flower language is eternal love, deep friendship, unchanging heart, eternal memory.
