Allium fistulosum is also called Allium fistulosum. Its leaves are as delicate and green as onions, and as slim as onions. Allium fistulosum is a very common plant, which can be seen in flower beds on campus and green belts in parks.

so how is the onion lotus cultivated? What good methods are there in breeding? What matters should we pay attention to when breeding onion lotus? Please read with me with questions! Cultivation method (basic knowledge) of Allium fistulosum:

Best breeding time: after the middle and late September

Best growing soil: sandy loam rich in humus and well drained

Growth humidity requirements: keep the basin soil moist, but can't accumulate water

Best growing temperature: 15 ~ 2℃

Best growing light: sunny, but also tolerant to semi-shade. Matters needing attention in raising Allium fistulosum in a warm and moist environment:

Fertilizer application: There are many requirements for fertilizer and water, but I am most afraid of indiscriminate fertilization, concentrated fertilization and partial application of nitrogen, phosphorus and potassium fertilizer, and it is required to follow the principle of "frequent application of light fertilizer, less quantity and more times, and complete nutrition".

watering points: during the growth of Allium fistulosum, water should be sufficient, and the soil should be kept moist frequently, but no water should accumulate. When the weather is dry, it is necessary to spray water on the leaves frequently to increase the air humidity, otherwise the tip of the leaves will be yellow and withered

Pot soil replacement: Allium fistulosum usually does not rotate the pot specially, but only changes the pot and replants it every year when combining with ramets. First, put 2 ~ 3 cm thick coarse substrate in the bottom of the basin as the filter layer, and then put the plants in.

pest control: pests are mainly harmful to Allium fistulosum, such as Spodoptera fistulosa, which mainly harms Allium fistulosum, Zhu Dinghong, Lycoris radiata and other plants, and is a secondary pest. When Spodoptera fistulosa is serious, it can eat all the stems above the ground of Allium fistulosum. Although the stem and leaf of Allium fistulosum can still germinate and grow after being eaten by the insect, it will not cause the death of Allium fistulosum, but its growth potential is obviously weakened.

Control methods

Turn the ground in winter or early spring, dig out the overwintering pupae, and reduce the population base; When larvae occur, spray 1,5 times of Miman, 1,5 times of Lethbone or 8 times of phoxim emulsifiable concentrate, and spray in the morning or evening when larvae come out to feed, which has better control effect. Water culture and soil culture of Allium fistulosum: Allium fistulosum can be planted in a water tank and grow bright leaves. In August, the plant height has reached more than 3 centimeters. At this time, dozens of flower stems can be pulled out, and by the end of September, white flowers will bloom. It is commendable that these flowers are all located below the water surface, and through the bright water body, they set off the glittering and translucent white onion orchids.

specific methods: prepare several glass fish tanks with a length of 9cm, a height of 5cm and a width of 35cm. At the beginning of April, in a long or round white plastic bag or shallow porcelain basin with a height of 4 cm to 5 cm, the full onion bulbs are spread out according to the plant spacing of 2 cm to 3 cm, and the roots should be stretched. Press the roots with clay, fill the soil until it is even with the upper part of the bulbs, gently compact the soil, cover it with a layer of coarse sand of .5 cm, and finally separate the bulbs with pebbles. After planting, sink the pot in a sink or pool, gently swing it from side to side, wash away the floating mud on the surface, and put it in a fish tank filled with water. The water in the fish tank should not be too full, and 4/5 of the tank height is appropriate. In order to increase the interest, some small tropical fish can be kept in the tank.

Soil culture of Allium fistulosum: The propagation of Allium fistulosum is mainly divided into plants and sowing, but it is best to plant bulbs separately in the second half of spring. Allium fistulosum is easy to divide balls naturally, and it is easy to reproduce by dividing plants.

ramet method

ramet propagation is carried out after the soil is thawed in early spring.

Method of plant division:

Take the mother plant out of the flowerpot, shake off the excess pot soil, separate the root system that is knotted together as far as possible, cut it into two or more plants with a sharp knife, and each plant that is separated should have a considerable root system, and its leaves should be properly trimmed to facilitate survival.

Pot disinfection

Soak the divided plants in chlorothalonil 15 times solution for five minutes, then take them out and dry them, and serve them in pots. You can also irrigate the roots with chlorothalonil immediately after serving in the basin.

management after dividing plants

after dividing plants into pots, irrigate roots or water them once. Because its root system is badly damaged and its water absorption capacity is extremely weak, it takes about 3-4 weeks to germinate new roots. Therefore, it is necessary to control watering within 3-4 weeks after rameting to avoid root rot, but the transpiration of its leaves is not affected. In order to maintain the water balance of leaves, it is necessary to spray the leaves 1-3 times a day (spray more at high temperature, spray less or not at low temperature). Don't fertilize it during this time. After branching, we should also pay attention to the strong sunlight, and it is best to put it in a shade shed for maintenance.

Seeding method

Seed collection

The lotus seeds become hot about 2 days after harvest. Harvest them in time. Because it was two seasons at that time, it was very easy for seeds to germinate on plants. Because it is afraid of heat in the whole growth period, and the optimum temperature for sowing is 15-2℃. Rescue is often carried out in autumn after the middle and late September.

sowing

stick the seeds on the surface of the substrate one by one, covering the substrate 1 cm thick. Then put the sown flowerpot into the water. The depth of the water is 1/2-2/3 of the height of the flowerpot, so that the water can slowly invade the ground and be planted at the same distance of 3cm× 3cm. After sowing, the substrate is covered, and the covering thickness is 2-3 times that of the seeds. After sowing, you can get wet with a sprayer. Later, when the soil in the basin is slightly dry. After watering again, we should still pay attention to the intensity of watering, so as not to rush the seeds over. Experience of cultivating Allium fistulosum:

Allium fistulosum likes sunshine, but it can also tolerate semi-shade. It requires a warm and humid environment and is suitable for sandy loam with rich humus and good drainage. Allium fistulosum is mostly barren, and it is mainly propagated by planting bulbs separately, usually in spring. When planting in the ground, sufficient base fertilizer should be applied, and the planting should not be too deep. Choose 3~4 bulbs to plant together, and generally plant them separately once every 3~4 years. The planting site should be sheltered from the wind and sunny, and the soil is fertile and humid. During the growth period, the soil should be kept moist, and the thin cake fertilizer water should be applied 2~3 times a year to grow well and bloom luxuriantly. If yellow leaves and residual flowers are found during the blooming period, they should be cut off and removed in time to maintain beauty and avoid consuming more nutrients. Onion is not cold-tolerant, and potted plants are needed in East China. Loose, fertile and well-drained culture soil should be selected for the basin soil, which can be prepared by mixing humus soil or peat soil, garden soil and river sand. During the growth period, water should be sufficient, and the basin soil should be kept moist frequently, but no water should be accumulated. When the weather is dry, it is necessary to spray water on the leaves frequently to increase the air humidity, otherwise the tip of the leaves will wither easily. In the vigorous growth season, thin liquid fertilizer should be applied once every half month. The sunshine intensity in northern midsummer is large, so it should be maintained in the shade, otherwise it will grow poorly and affect flowering. If you can keep a certain temperature after entering the room in winter, you can still continue to grow and bloom.
