Heartleaf false pickerelweed (Monochoria korsakowii), also called oval-leaved pondweed, is a species of plant in the Heartleaf false pickerelweed family. Heartleaf false pickerelweed grows mainly in shallow pools, ponds, ditches or swamps. This plant is found in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Henan, Shandong, Shanxi, Shaanxi, Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei, Hunan and other provinces of China. In addition, North Korea, Russia, and Japan also have it.
Heartleaf false pickerelweed Flower is big and beautiful, light blue, like a flying bluebird, so it is also called the bluebird flower. The leaf color is green, bright, simple and elegant. Heartleaf false pickerelweed is often used with other aquatic ornamental plants in Garden waterscape layout, which is an excellent and beautiful aquatic flower. The inflorescences can be used for cutting and arranging flowers.The whole grass can be used as fodder for livestock and poultry, and can also be used as medicine. It has the effect of clearing away heat and detoxification and reducing swelling.
Heartleaf false pickerelweed is an erect aquatic herb. Rhizome is stout, with soft fibrous roots.Stems erect, 30-70 cm tall, whole plant smooth glabrous, base sometimes purplish red. Leaves are basal and cauline; Basal leaves are broadly ovate-cordate, 4 -- 10 cm long and 3 -- 8 cm wide, apically acute or acuminate, base cordate, entire, with many arc-shaped veins; Petiole is up to 30 cm long, sometimes enlarged into a saccate; Cauline leaf petiole gradually short, the base increases into a sheath, holding the stem.
Racemes of Heartleaf false pickerelweed are terminal, sometimes paniculate; Flowers are more than 10, pedicels 5 -- 10 mm long; Perianth segments are elliptic, 10-14 mm long, apically obtuse, bluish; Heartleaf false pickerelweed has 6 stamens, among which 1 is large, the petals are oblong and pale blue, the others are smaller, the anthers are yellow and the filaments are filiform. Capsule is ovoid, 10-12 mm long. Seeds are oblong, ca. 1.5 mm long, longitudinally ribbed.
Heartleaf false pickerelweed is a hardy species found near marshes, ditches and ponds.It grows mainly in shallow pools, ponds, ditches or swamps.
Heartleaf false pickerelweed likes warm weather, but in the summer, the high temperature and sultry environment (35℃ or more with relative humidity above 80%) is not conducive to its growth. The winter temperature requirements are very strict, when the ambient temperature is below 10℃ to stop growth, in the frost can not be safe overwintering.
1. In the growth environment above 34℃, the correct treatment method is:
(1) Strengthen the air convection as much as possible so as to facilitate its transpiration and reduce the temperature in the body;
(2) To leaf spray, 2 ~ 4 times a day: the higher the temperature, the corresponding number of times is also more.When the temperature is low or rainy, spray less or not spray;
(3) Spray wet the ground around it, which is very helpful to reduce the temperature of the environment around it.
2. In the growth environment below 0℃, the correct treatment method is:
(1) Move it to a room not lower than 0℃ for wintering;
(2) If it cannot be moved, it must be wrapped in straw or buried with earth;
(3) When the temperature drops further, consider wrapping it in a film, but remove the film every two days to allow air to breathe at high noon temperatures.
Heartleaf false pickerelweed in the summer heat (daytime temperatures above 35 ° C), if placed in direct sunlight, will grow very slow or semi-dormant state, and the leaves will burn and slowly yellow, shed.Therefore, in the hot summer to give it to block about 50 percent of the sun.
In spring, autumn and winter, because the temperature is not very high, it is necessary to give it direct sunlight, in order to facilitate its photosynthesis and the formation of flower buds, flowering, fruiting. Put in indoor maintenance, put in the place that has bright light as far as possible, wait for a place like the sitting room with good daylighting, bedroom, study. After indoor maintenance for a period of time (two months or so), it is necessary to move it to the outdoor shade (winter heat preservation conditions) of the place for maintenance for a period of time (a month or so), so alternate.
With other brews, water demand is more, but the most afraid of chaos fertilization, concentrated fertilizer and n, p, k, required to follow the "light weight more frequently, and less time and complete nutrition" and "room of dry wet, dry to dry, not stem not watering, watering is drenched the" principles of two fertilization (water), and after fertilization, the evening want to keep dry leaf and flower:
(1) Autumn: after a period of recovery from sowing seedlings on the pot, the fertilizer and water management should be quickly followed up. Fertilizer and water management follows the sequential cycle of "Huabao" -- "Huabao" -- "Huabao" -- "Huabao" -- "Huabao" -- "Qingshui", the interval period is about 1 ~ 3 days, and irrigation is conducted one cut or two days according to the weather and air humidity.
(2) Winter: Although Heartleaf false pickerelweed still continues to grow, the low temperature will slow its growth rate, and it does not require much fertilizer and water, and it even needs to control fertilizer and water. Fertilization and water management follows the sequential cycle of "Huabao" -- clear water -- clear water -- "Huabao" -- clear water -- clear water, with an interval of about 4 ~ 7 days. The watering time should be arranged as far as possible on sunny days when the temperature is high at noon.
(3) Spring: after the temperature rises, the growth recovers rapidly, and gradually enters the stage of flower bud differentiation and flowering, which requires a lot of fertilizer and water. Fertilizer and water management follows the sequential cycle of "Huabao" -- "Huabao" -- "Qingshui", with an interval of about 2 ~ 4 days. Fertilizer supply will be stopped after entering the Fruit 'stage.
Heartleaf false pickerelweed usually starts sowing in autumn: The best way to disinfect the substrate used for sowing is to put it in a wok and heat it up. It will kill any disease. Soak the seeds in warm water (about the same temperature as your face wash) for 3 to 10 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this job can be left out.
Heartleaf false pickerelweed likes light and shade.In order to flourish, the plants should receive at least 4 hours of direct sunlight each day. It likes warmth and is not cold resistant. Heartleaf false pickerelweed grows well in the temperature range of 18 ~ 32℃, and its overwintering temperature should not be lower than 4℃. Under good management conditions, Heartleaf false pickerelweed is not susceptible to disease and is less susceptible to invasion by harmful animals.In the open water culture, mosquitoes often breed. Some small fish can be put into ponds and POTS to remove larvae.
Heartleaf false pickerelweed is perennial, its seedling is rapid, is easy to age.The best viewing time of pond growers can reach to 3 ~ 4 months after forming. The best viewing time for potted plants is only from April to May after forming. Seedlings should be separated each year in order to renew the plants and ensure their strong growth.
The Heartleaf false pickerelweed family is a completely aquatic family with about 39 species of 9 genera and is found in tropical, subtropical, and temperate freshwater.
