2. Sowing: Good color sowing and propagation is relatively simple, but seeds are not easy to obtain and last for a relatively long time. When sowing, the temperature should be controlled above 65438 06℃, and acid pot soil should be selected, and sowing should be carried out after the temperature rises in the morning. After sowing, cover with chopped moss or plastic film to keep moisture. After sowing, the temperature is controlled at 25 ~ 30℃, and seedlings can emerge in about 25 days.
3. Tissue culture: At present, Haocai also adopts the method of tissue culture, that is, culture in Petri dishes in a sterile environment. Although the domestic technology can't meet the requirements now, the quality of good lottery propagated by this method is better and the number of breeding is large.
Conditions and requirements 1. Lighting: In Lucky Strike, lighting plays an important role in aquaculture. You need at least 4 to 5 hours of sunshine every day in the cold season. Cloudy days can use light instead of sunlight, so it is not suitable for exposure, and it should be placed in a cool place in summer.
2. Temperature: The suitable temperature for good luck is 15℃ to 22℃, and the lowest temperature in winter can't be lower than 10℃, otherwise it will cause freezing damage to plants, yellow leaves and affect the robust growth of plants.
3. Soil: Haocai is suitable for the growth of loose, fertile and humus-rich soil. Two parts of peat soil can be mixed with 1 part of fine sand to make culture soil.
4. Fertilizer: In good luck, the flowering period should be full of fertilizer. Usually, rare organic liquid fertilizer is applied once every two weeks, such as bean cake, sesame sauce residue soaking solution, soybean soaking solution or fermented rice washing water.
5. Humidity: Haocai likes humid environment. Keep the soil moist on weekdays, and generally do not water it in rainy days. For family rearing, it is best to use dry purified water instead of tap water.
6. Pests and diseases: Haocai is prone to pests and diseases in high temperature, high humidity and poor ventilation. If diseases are found, carbendazim can be sprayed in time, and omethoate can also be sprayed on pests.
Matters needing attention in the Lucky Strike
1, good color likes cold and warm, likes humid and semi-cloudy environment, and avoids direct glare. If the light is too strong, the leaves will be yellow, mottled and faded, thus losing their ornamental value, so they should be shaded by 50-60% in spring, summer and autumn. Haocai and other red-backed varieties prefer light, and the leaves are brightly colored in strong sunlight, so they should be maintained on sunny windowsills and balconies. Suitable for growing in loose, ventilated and water-permeable soil.
2. The auspicious growth temperature is 18 ~ 30℃, the suitable temperature is 20 ~ 25℃, and the lowest temperature is above 12 ~ 15℃. It is safe to overwinter above 10 ~ 12℃ in winter, and vulnerable to cold damage below 10℃, and the suitable temperature is 16 ~ 20℃. If the temperature is too high in summer, the leaves will become dry and sharp because of too much water. Therefore, attention should be paid to spraying leaves frequently, increasing air humidity, shading appropriately, and strengthening ventilation and cooling.
3. Haocai prefers acidity, requiring the pH value of water to be 5.5 ~ 6.5, and dislikes salt, especially calcium salt and sodium salt. If the pH value is higher than 7, plants can't absorb nutrients well, their leaves lose luster and their photosynthetic capacity decreases, which is easy to cause heart rot and root rot. Hard water contains too many calcium and magnesium salts, so it is not suitable for use. Tap water contains a lot of chlorine and sodium, so it is not suitable for use. Groundwater varies greatly due to different geographical components, and should be used after water quality analysis. In addition, good colors are most afraid of soaking, and the water content of the substrate is too high, and the drainage or permeability is poor, which often causes rotten roots and rotten hearts.
4. The suitable relative humidity for good luck is 50 ~ 75%. Above 80%, it is necessary to strengthen ventilation, otherwise it is easy to get sick or grow too fast. When it is lower than 40%, it is easy to cause blade tip withering, so it is necessary to spray water regularly or humidify it with high-pressure spray humidification system. During the period of high temperature and high humidity in summer, ventilation should be strengthened as much as possible, but it is not advisable to spray more water during the period of low temperature in winter and more water during the period of high temperature and drying in spring.
