The latest culture methods of asparagus

Asparagus, also known as Yunpian pine, prickly asparagus, cloud bamboo, etc., is an evergreen plant belonging to the asparagus family, with slightly fleshy roots, soft and clumpy stems, up to a few meters high, with extremely high ornamental plants, which can be placed in the living room and study, purifying the air and adding a scholarly flavor at the same time. Let's take a look at the breeding methods of asparagus.

Culture environment of asparagus

Asparagus likes warm, humid and semi-overcast 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. It is better to cultivate loose, fertile and well-drained sandy loam rich in humus. It is suitable to keep the room temperature between 12-18 ℃, ventilation and heat dissipation when the temperature is over 20 ℃, the suitable growth temperature is 15-25 ℃, and the overwintering temperature is 5 ℃. Born in the mountains, but also cultivated in the garden.

Propagation methods of asparagus

1. Sowing: 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. Sowing in early April 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 basin or wooden box. Put the seeds on the basin soil at a distance of 2 cm to 3 cm, 2 to 3 seeds in each hole. After sowing, it is covered with fine sand 5 mm thick, covered with glass or plastic film, the temperature is kept at 20: 25 ℃, and water is often sprayed to keep the basin soil moist. About 30 days after sowing, the seedlings began to sprout. When the height of the seedling is 4-5 cm, it can be transplanted and cultured, and when it is 8-10 cm, it can be planted in the pot.

2. Ramet: the 3 ~ 5-year-old plants of asparagus grow thickly and can be propagated. When changing pots in spring, use a sharp knife to divide the tufted stems and roots into 2-3 clumps, so that each clump contains 3-5 branches and buds, and then plant them on the pot. When ramet, damage the root system as little as possible, water thoroughly after planting, put it in a semi-shady place, and pay attention to moisturizing and shading. Watering should be properly controlled in the future, otherwise it is easy to cause yellow leaves.

Bonsai production of asparagus

1. Material selection first: one asparagus with a height of about 20 cm, two asparagus with a height of more than 10 cm, a shallow basin of irregular white marble and its supporting frames, a number of rocks with a height of about 10 cm, and an appropriate amount of soil and moss.

2. Bonsai shaping: spread a thin layer of cultivation soil on the shallow basin surface of white marble, plant the tallest asparagus and curved branches and leaves to the right end of the basin, plant the second height asparagus not far from the left side of the first asparagus on the right side of the basin, and then put the shortest asparagus at the junction of 1ploke 3 and 2x3, and the curved branches and leaves of asparagus should also be to the left, so as to achieve the coordination and unity of the three asparagus. Then adjust the position of asparagus in the basin to achieve natural beauty.

3. Point stone and spread moss: put a number of mountains and stones on the basin surface on the right side, and cover the moss on the basin surface to achieve the artistic effect of greening. Finally, spray asparagus and moss with clean water to make the culture soil moist.

Culture methods of asparagus

1. Pot soil: fertile sandy loam should be used in the cultivation basin soil of 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 the soil should be changed and fertilized regularly. 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 for fertilizer, but it can not be short of fertilizer. Limited by potted soil, nutrients must be replenished in time to meet the growth requirements. In the process of fertilization, it is necessary to apply more and less, and do not apply thick fertilizer, otherwise it will cause leaf yellow. 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. Do not apply too much fertilizer at flowering stage, and topdressing liquid fertilizer 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.
