How to raise asparagus culture methods and matters needing attention

Asparagus is a kind of plant produced abroad, which was introduced and cultivated by our country. At present, it is still widely distributed in our country. Asparagus is highly ornamental, and many people like to raise it at home. However, when breeding, it must be that most people still want to have a comprehensive understanding of its breeding technology.

How to raise asparagus

1. Temperature and environment. The most suitable growth temperature of asparagus is about 20 ℃, and the temperature is more than 10 ℃ in winter. If the temperature is too low, freezing injury may occur. When the weather is too cold in winter, you can put a layer of plastic film on the outside of the potted plant to keep warm. In addition, the higher the air humidity, the better. In hot weather, often sprinkle water on the ground and leaves around plants to increase air humidity.

2. Soil. The soil should be loose and fertile. Asparagus has high requirements for soil drainage and air permeability, so it is best to choose humus-rich soil, peat soil and other loose soil with good drainage. Adding a little organic fertilizer to the soil as base fertilizer is beneficial to the growth of plants.

3. Light. Asparagus likes semi-overcast environment, it is best to put it indoors with astigmatism, except in winter, other seasons should not be placed in the sun, especially in summer, because the sun is more poisonous, it will burn branches and leaves, generally speaking, if you want to be placed in the sun in spring, summer and autumn, it should be 60% shielded.

Culture methods and matters needing attention of asparagus

1. Culture methods:

1. Watering asparagus is fleshy root, watering should be careful. Each watering should be thoroughly watered, not half of the water, so that the rhizome will not be able to absorb water and die. The amount of water should not be too much, not too little, and should be reasonably grasped. When the basin soil is slightly dry, it needs to be watered in time. It is necessary to "dry and water thoroughly". The winter weather is cold and the water evaporates slowly, so the amount of water should be reduced to avoid frostbite. If the room is too dry, water should be sprayed to the leaves in time to increase the air humidity.

2. Fertilization can be applied every half a month during the growing period, and liquid fertilizer can be applied together with watering. However, during the dormant period of high temperature in summer and low temperature in winter, fertilization should be stopped. The plant must have sufficient nutrients to grow when it is young, but the amount of fertilizer should be reduced after the plant is stereotyped, so as not to affect the beauty of the plant shape.

2. points for attention:

1. Asparagus can not be cultured outdoors in northern winter, so asparagus should be moved indoors in time to provide a warm growing environment. Asparagus can not be watered too frequently and can be kept moist by spraying water on the leaves.

2. Spray water once or twice a day in summer and once every 3-4 days in winter. Don't water directly with tap water. Should be placed 1-2 days in advance, release the chlorine in the water, etc., to ensure that the water temperature will not be too cold.

What if the leaves of asparagus turn yellow?

1. Overwatering. If there is too much watering, you can not water temporarily, but only spray water to the leaves to moisturize asparagus.

2. The light is too strong. Move the flowerpot to a cool place, and spray more water to the branches and leaves to increase humidity, water evaporation will take away a certain amount of heat, can cool asparagus.

3. Improper temperature. The solution is to keep asparagus in an environment of about 15 degrees, and can be irradiated with appropriate astigmatism and weak light.

4. Improper fertilization. If there is not enough fertilizer, it is recommended to increase the amount of chemical fertilizer to provide the nutrients needed by asparagus.

How to make asparagus blossom

Before asparagus blossoms, we should pay attention to timely fertilization and apply more phosphorus and potassium fertilizer to promote flowering. Keep the leaves of asparagus moist and often spray water on the leaves to prevent and control the withered and yellow leaves. Most of the asparagus planted by the family are kept indoors and do not blossom because they do not get enough light. To blossom, you need to put the plant on the balcony where there is plenty of sunshine, so that it can receive sunlight sooner or later, and appropriate sunshade at noon. Meeting the above three conditions, asparagus, which has been cultivated for 4 or 5 years, should be able to blossom and bear fruit.

In fact, the breeding skills of asparagus are not difficult, we can start from its growth habits. In breeding, we must pay attention to the control of soil and light, it should not be exposed to the sun, just put it in a ventilated environment. In the later stage of breeding, it is necessary to strengthen the management of fertilizer and water, so that asparagus will grow well.
