A breeding method for sudden laughter

Suddenly laugh, also known as iron arrow, yellow Lycoris, etc., for the Lycoris family Lycoris perennial herbs, in the garden can do under the forest ground cover flowers, flower border planting or natural planting between mountains and rocks, because of its flowering time leaves, so it should be matched with other more tolerant herbs, with the characteristics of strong scape and long flower stalk, let's take a look at the breeding method of laughing suddenly!

The growth habit of sudden laughter

Suddenly laugh like the sun, wet environment such as shady and wet hillsides, rocks and stone cliffs, but also can withstand semi-shade and dry environment, slightly cold-resistant, strong vitality, no strict requirements for the soil, such as fertile soil and good drainage, the flowers are particularly prosperous. Distributed in Fujian, Taiwan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Yunnan, Japan and Myanmar.

The breeding method of sudden laughter

1. Ball division propagation: the ball division method is the simplest and most commonly used method of propagation. The plant is dug up during the dormant period or after flowering, and the epiphytic bulbs near the mother ball are removed and planted, and they can blossom after about a year or two.

2. Scale cutting: the cleaned bulb base was cut into rice shape, and the depth of bulb length was 1x2px3. After disinfection and shade drying, it was inserted into moist sand, perlite and other substrates. After separation and cultivation, seedlings could be formed.

3. Tissue culture: MS medium was used for tissue culture of Michelia vulgaris. Pedicel and ovary were used as explants. Callus could be formed at the incision, adventitious roots could be formed after 1 month, and adventitious buds could be formed after 3-4 months.

The breeding method of suddenly laughing

1, temperature: suddenly laugh like warmth, cold resistance is not high, high temperature resistance is not very good, so the temperature during the culture period can not exceed 30 degrees, nor lower than 8 degrees Celsius, the average temperature should be kept at least 24 degrees Celsius.

2. Watering: suddenly laugh and like to be wet, especially during the growth period, always pay attention to keep the soil moist, but not too much watering at the same time, to avoid stagnant water, resulting in plant bulb rot.

3. Fertilization: in general, it is enough to apply fertilizer 2 to 4 times a year. The first time is to apply organic fertilizer or compound fertilizer before flowering, and the second time is to apply nitrogen fertilizer, phosphorus and potassium fertilizer after flowering at the end of October.

Disease and pest control of sudden laughter

1. Carbon blast: the common diseases of Hudixiao are charcoal blast. The bulbs were soaked in 0.3% copper sulfate solution for 30 minutes before planting, washed and dried with water, sprayed with 50% carbendazim wettable powder every half a month, and sprayed with 50% benzoate 2500 times solution at the initial stage of the disease.

2. Spodoptera litura: Spodoptera litura mainly harms leaves, buds and fruits by larvae, gnaws on mesophyll and bites scape and seeds, generally from late spring to November. It can be controlled with 2500 times of 5% Regent suspension and 1000 times of Wanling.

3. Lycoris radiata: it can be combined with turning the ground in winter or early spring to dig out the overwintering pupae and reduce the population number. Spraying 1500 times of Lexben or phoxim EC at the time of occurrence, the spray effect was better when the larvae came out to feed in the morning or evening.

4. Thrips: thrips mainly absorb nutrients at the hair leaves of the bulbs, resulting in the loss of green leaves, especially after the fruit is ripe. It can be controlled by rotating spray with 3000 times of imidacloprid and 70% amyl 6000 times.
