How to plant forget-me-not

Cultivation type

If it is an annual cultivation, the seedlings of early-maturing varieties that have been subjected to low temperature treatment are selected, planted in April to June every year, and the flowers bloom in autumn, and the cut flowers continue throughout the winter until the following spring, mainly for winter flowers. Pay attention to proper shading and cooling in hot weather in summer, and do a good job of heat preservation in winter. As a biennial cultivation, seedlings are planted in October to December every year, so that the seedlings can fully accept the natural low temperature in winter, and bloom in the next spring, which can last until the winter of that year, and be eradicated after the winter flower production.

forget-me-not-soil colonization

forget-me-not-me-not-not-very-demanding soil, but loose and breathable sandy loam with deep soil layer is better. Before planting, adjust the pH of soil to make it slightly alkaline. The amount of base fertilizer accounts for 7% of the total amount of fertilizer, and it should contain 1.75 kg of nitrogen, 2. kg of phosphorus, 2.1 kg of potassium and .14 kg of boron per 1 m 2 planting beds. Slow-acting compound fertilizer and decomposed organic fertilizer are used as the base fertilizer, and they are evenly turned into human soil after application. Leveling the border, the border is about 2cm high. The plant spacing is 3 cm× 4 cm, and the two rows are staggered. If three rows are planted, the three rows are staggered, which is beneficial to ventilation and light transmission. Seedling planting should not be too deep, and the planting depth should be flush with the rhizome and soil surface, and it should be watered in time after planting.

fertilizer and water management

during the growth period, 7% of nitrogen and potassium are used as base fertilizer, 3% as topdressing, and all phosphorus fertilizers are used as base fertilizer, and topdressing is usually once a season. Topdressing potassium fertilizer and boron fertilizer at flowering stage is beneficial to improve the quality and yield of cut flowers.

don't forget me, like a dry and well-drained environment, and avoid waterlogging. The watering amount should be properly controlled throughout the growth period, otherwise it will lead to the decline of flowering quality and yield.

water and fertilizer management

when the seedlings survive and start to grow, topdressing should be carried out with irrigation every 1 days, and the mixed solution of 2 mg/kg nitrogen fertilizer and 1 mg/kg potassium fertilizer should be added to the water for fertilization. Keep the soil moist during the seedling period, and pay attention to regular intertillage weeding to promote the healthy development of the root system of the seedling. About 2 months after the seedlings were planted, they began to shoot flowers. The lover grass in the flowering period should be full of water and fertilizer, otherwise the flowers will be short and the flowers will not flourish. 2 mg/kg mixed liquid of nitrogen and potassium can be supplemented in irrigation water, and the fertilizer can be applied once every 1 days or so. At bolting and flowering stage, in addition to topdressing liquid fertilizer, the mixed solution of .1% potassium dihydrogen phosphate and .1% boric acid should be used for foliar spraying to improve the yield and quality of cut flowers of Lovegrass.

temperature management

I suddenly forget myself and like cool environment, but I am afraid of high temperature weather. It is best to control the ambient temperature at 12 ~ 2℃ in cultivated species. Forget-me-not plants have strong cold resistance. Under the natural temperature conditions in Kunming in winter, some varieties can overwinter in the open air. Most varieties will sprout and blossom in the next spring as long as their roots have fully grown before winter, even if some leaves on the ground die. However, forget-me-not flowering is extremely sensitive to low temperature reaction. Only when the temperature reaches above 2℃ during the day and not lower than 1℃ at night can the flower branches grow and bloom.

illumination

forgetting oneself suddenly can only grow normally under sufficient sunlight. If the environment is shaded, although the bushes are lush, there are few flowering buds. Therefore, plants should be exposed to sunlight for more than 4 hours every day. If full sunshine can be guaranteed, the growth will be better.

flower branch fixation

To produce high-quality forgotten cut flowers, it is usually necessary to pull the net to fix the flower branches. The specific method is to pull a layer of net rack 2 ~ 3 cm away from the ground before bolting, and then cover the place 45 cm away from the ground with a second layer of net after the plants grow flowers. With the growth of flower branches, guide them into the grid in time to keep the scape upright.

shaping and pruning

forget yourself. During the growth period, the sprouted flower branches should be treated differently according to the size of the seedlings. For plants that have grown larger and the leaves between plants are basically closed, 4 ~ 5 flower branches are reserved for each plant to grow and bloom; For small plants, the flowering branches can be removed to prevent them from flowering temporarily, so that their plants can grow fully, laying the foundation for the production of high-quality cut flowers, and then let them enter the flowering period when the plants grow fully. During this period, it is also necessary to regularly remove the newly-sprouted thin flower branches to concentrate nutrients for opening the flower branches, improve the ventilation and light transmission conditions inside the plants, reduce the number of blind flowers in the middle and lower parts of the plants, and improve the quality of single flower branches. After the amount of cut flowers exceeds 5%, it is necessary to start to cultivate the next flowering branch. The practice is to keep a small number of newly-sprouted flower branches in this period, and after all the flowers are cut in the last crop, the remaining flower branches have grown to a certain height, thus effectively shortening the time between two crops of flowers and enabling Lovegrass to continuously bloom and supply the market.

cut flowers and marketing

when the petals on each small flower branch are spread to 3% and all inflorescences are colored, they can be cut. When picking flowers in the morning or evening, it should be cut from the base of the plant, especially at the early stage of cutting, which can promote the axillary bud germination of the plant. After cutting, the base of the flower branch is immersed in the fresh-keeping liquid to keep the water content of the flower branch sufficient for marketing. Forget-me-not cut flowers can be stored for 2 ~ 3 weeks at about 2℃.

pest control

The diseases of forgetting me suddenly include gray mold, powdery mildew, virus disease and so on. Botrytis cinerea can be controlled by spraying 8 ~ 1 chlorothalonil and thiophanate methyl continuously for 3 ~ 4 times. Powdery mildew can be prevented and controlled by spraying fenxiuning, and virus diseases can be mainly prevented and controlled by pulling out diseased plants in time and burning them, spraying pesticides to prevent insect-borne diseases. Scale insects are the most common pests of Phyllostachys praecox, which can be washed with an old toothbrush and sprayed with 4% omethoate EC 1 times.

introduction

forget-me-not (scientific name: Myosotis sylvatica) is a plant belonging to the genus forget-me-not of Lithocarpaceae. Forget-me-not is a perennial herb with a height of 3-6cm. Verticillate cymes, 1-15cm; long; Don't forget me, there are light blue flowers, and the flowering period is April-May. Strong adaptability, like dry and cool climate, avoid damp heat, like light, drought-resistant, and the suitable growth temperature is 2℃-25℃.

It is distributed in Europe, Iran, Russia, Pakistan, Kashmir, India and Jiangsu, Northwest China, North China, Sichuan, Yunnan, Northeast China and other places in Chinese mainland. It grows in areas from 2 meters to 4,2 meters above sea level. Mostly in mountain forest margins, hillsides, forests and valley grasslands. It has not been artificially introduced and cultivated.

The "Don't forget me" commonly made into dried flowers in the market is actually a plant of Limonium called Limonium. Please pay attention to distinguish it.
