How to raise grape hyacinth culture methods and matters needing attention

Grape hyacinth is a very ornamental plant, its shape is similar to that of ordinary hyacinths, and the flowers are blue and coated, looking like small grapes, so it has the origin of the name. Nowadays, there are many people who breed grape hyacinth, and they still need to master some skills before breeding.

How to raise grape hyacinth

1. Illumination: grape hyacinth only needs more than 5000Lx to maintain normal physiological activity. If the light is too weak, the plant will be thin, the stem is too long, the bud is small, the flowers are early, and the leaves are yellow. incandescent lamp can be used to fill the light at about 1 meter, but too strong light can also cause leaves and petals to burn or shorten the flowering period.

2. Humidity: soil moisture should be kept between 60-70%, too high, root respiration is inhibited and perishable, and if it is too low, the aboveground part wilts or even dies; the air humidity should be kept at about 80%, and can be increased by spraying and ground watering, and can also be reduced by means of ventilation and ventilation.

Culture methods and matters needing attention of grape hyacinth

1. Culture methods:

1. Grape hyacinth is generally cultivated in autumn and winter every year. The soil we cultivate grape hyacinth had better choose more fertile soil with good drainage performance. Rotten leaf soil and sandy loam are good soil for planting grape hyacinth.

2. After planting the grape hyacinth bulb, immediately water it thoroughly, and then put it in a sunny place to cultivate it. During this period, it should be watered frequently to keep the soil moist.

3. after the inflorescence grows, we should plant the grape hyacinth in a semi-cool place, so that the inflorescence can grow rapidly, and the environment for planting grape hyacinth should be kept between 15 °C and 20 °C, which is beneficial to plant growth.

2. points for attention:

When planting the bulb of grape hyacinth, be careful to leak out the stem of the bulb. We plant the bulbs in wet soil and water them immediately. After that, we should water less or no water, but be careful not to let the soil dry.

What about the rotten roots of grape hyacinth?

1, the root of grape hyacinth is different from other plants, the root system grows on the bulb, if it is only rotten root, that is no problem, clean up the rotten root system directly, then disinfect it with potassium permanganate solution, dry it in a cool place, replant it in the soil, and don't continue hydroponics, so there is a good chance of saving it.

2. If the bulb is also rotten, be sure to clean the moldy area, peel off the rotten part, carefully check the depth of the surrounding ball for Flemish marks, and then disinfect and dry and replant.

Common diseases of grape hyacinth and their control

1. Yellow rot: control method: choose a strong sterile seed ball when planting. Disinfect the bulb and soil with formalin solution before planting. If you want to carry out hydroponics, you should choose clean water without pollution. Carbendazim solution can be sprayed at the time of onset, once every 2 to 3 days, and the symptoms can be relieved for 3 to 5 times.

2. Artemisia nuclear disease. Control method: choose strong aseptic seed ball when planting. The pot soil was disinfected with pentachloronitrobenzene, sprinkled directly in the soil, stirred evenly and then planted. Diseased plants should be treated in time, and diseased leaves should be removed in time.

3.Botrytis cinerea. Prevention and treatment: reduce the source of infection: find diseased leaves and remove them in time. Chemical control: Bordeaux solution was sprayed, mixed according to the ratio of 1: 1 / 1000, sprayed 2 times 3 times, 1 / 2 days apart.

4. Root nodule disease. Prevention and control methods: the bulbs should be strictly sterilized during the storage period, and the storage environment should be well ventilated and the temperature should be suitable. Check once a week to see if it is abnormal and burn the diseased plant in time. The soil must be disinfected before planting. Careful maintenance, found that there are dead branches and leaves on the soil surface should be removed in time. Do not often turn the root in the process of maintenance, so as not to hurt the root system and increase the probability of disease.

Grape hyacinth in breeding must do a good job in light and temperature management, in breeding also need to strengthen the control of water charges, too much or too little is not good. When grape hyacinth is cultivated, if there is a phenomenon of rotten roots, do not panic, first find out the cause, and then thoroughly solve the problem from the root.
