How to reproduce asparagus best?

Asparagus is a very high ornamental plant, can be placed in the living room, study, purify the air at the same time also add bookish flavor. There are many friends who like asparagus. Although asparagus is not bamboo, its branches are knotted like bamboo and its posture is very beautiful. Many friends who cultivate asparagus do not know how to reproduce asparagus. Today, the editor will introduce the breeding methods of asparagus.

Growth conditions of asparagus

1. Asparagus likes warm, humid and semi-overcast and ventilated environment, can't bear cold and drought in winter, can't pour too much water, root will rot, and avoid direct sunlight in summer.

2. The soil should be cultivated in sandy soil rich in humus, which is loose, fertile and well drained.

3. It is suitable to keep the room temperature between 12-18 ℃, ventilation and heat dissipation when it is more than 20 ℃, the suitable temperature for growth is 15-25 ℃, and the overwintering temperature is 5 ℃.

Sowing and propagation of asparagus

Sowing is the main method of propagation of asparagus. When the pericarp of asparagus seed blackens and softens, it is ripe, then it should be picked gradually according to the degree of maturity, rubbed to remove the pulp, cleaned with clean water, dried and stored semi-dry.

The sowing and propagation of asparagus is generally sowed in early April, and it can be used as a commercial seedling or furnished indoors in the autumn of that year. The sowing substrate is generally fine sand, and the container is tile pot or wooden box. The seeds are placed on the basin soil at a distance of 2-3 cm, 2-3 seeds per hole. After sowing, it is covered with fine sand 5 mm thick, covered with glass or plastic film, the temperature is maintained at 20-25 ℃, and water is often sprayed to keep the basin soil moist. About 30 days after sowing, the seedlings begin to germinate and emerge. When the seedlings are 4-5 cm high, they can be transplanted and cultured, and 8-10 cm can be planted on the pot.

Ramet Propagation of asparagus

The family potted plants of asparagus can also be propagated by individual plants, and the clumps of asparagus are strong. The 4-5-year-old plants can sprout root tillers from the rhizosphere continuously, so that the clumps of plants can be expanded continuously. In spring, the pots can be changed, and the potted plants can be divided into tufts and planted in pots respectively to obtain new plants.

Family Culture of asparagus

1. Potted soil: fertile sandy loam should be used to cultivate asparagus, which should be warm and humid, rich in rotten branches and good drainage. Generally, it can be prepared in the proportion of 4 parts of garden soil, 2 parts of rotten leaf soil, 2 parts of compost soil and 1 part of sand. And to change the soil regularly to add fertilizer. If excessive fertilization causes "watering roots", it is necessary to pour the pot to remove the fertilizer, irrigate the soil with clean water, and then put it into the new soil for breeding.

2. Watering: watering is the key point of asparagus cultivation and culture. too much watering and too wet basin soil can easily cause root rot, and too little watering will lead to scorched and yellowed leaf tips. Therefore, in the process of watering, it depends on the weather, growth and the dry and wet condition of the basin soil, so that if it is not dry, it will be watered thoroughly. When the weather is hot and dry, water spraying can be used to humidify and cool the leaves, but less watering is needed in winter.

3. Fertilization: asparagus is not good at fertilizer, but it can not be short of fertilizer. Limited by potted soil, asparagus culture must replenish nutrients in time to meet the growth requirements. In the process of fertilizing asparagus, it is necessary to apply more times and less amount, and do not apply thick fertilizer, otherwise it will cause leaf yellowing. Generally, you can choose to apply rotten thin liquid fertilizer once a month, and after the plant grows and finalizes, you can properly control and reduce fertilization. During the growing period, thin fertilizers containing ammonia and phosphorus should be applied once or twice a month to promote the growth of branches and leaves, as well as other liquid fertilizers. It should be noted that not too much fertilizer should be applied at flowering stage, and liquid fertilizer should be applied twice in May-June and September-October respectively.

4. Lighting: asparagus culture can not be exposed to the hot sun, hot season, should be placed in a cool and ventilated place. At the same time, asparagus flowering is not only afraid of wind, but also afraid of rain, should pay attention to good ventilation, good weather can be properly placed outside to receive sunlight. The temperature of potted asparagus in winter should be kept above 5 ℃ to avoid freezing.

5. Display: asparagus loves a clean and well-ventilated environment. If stimulated by harmful gases such as smoke, gas and pesticides, the leaves will turn yellow, curl and even die. Therefore, asparagus should be placed in a clean, well-ventilated environment, away from marble decorative materials that release mercury gas.

6. Plant pruning

Lack of pruning of ① leafy branches: when the growth position of leafy branches on the main branch is not ideal or missing for some reason, short pruning can be carried out in the appropriate position of the main branch to force the hidden buds to germinate. In general, the height of truncation is the height of leafy branch germination, and the position of prickles on the branch is the location of leafy branch germination, and the thicker the branch is, the higher the germination rate of hidden bud is.

② whole plant renewal pruning: if the branches and leaves of the whole plant grow poorly due to strong sunburn or basin soil over-drying, lack of fertilizer and some unknown reason, the whole plant can be renewed. When renewing and pruning, all the leafy branches can be cut off, but we should pay attention to the parts of the branches, because they determine whether the distribution of the remaining branches is uniform. Pruning in the growing season is generally high and easy to sprout new branches, and the amount of water should be reduced appropriately after pruning, never make the basin soil too wet, otherwise it will lead to pruning failure.
