It can also be sown and propagated. A large number of seedlings can be obtained by sowing but due to complicated operation, low survival rate and long seedling cycle. At the beginning of summer till the small full season, the newly collected seeds can be sown after being placed in a cool and ventilated place to dry. In order to increase the germination rate and early emergence, the seeds can be soaked in a concentration of 1%-2% permanganate at about 30°C. Potassium solution for 1 to 2 hours, can be sown after taking out and drying, cover soil about lcm and pay attention to keep moist and shading ventilation, 7-10 days to emerge.
ã€Cultivation management】
Any plant that is a positive species of the genus Jacaranda must be placed in a full sun or half-day environment, regardless of whether it is planted or potted. When the seedling grows 3--5 pairs of leaves, it can be carried on the basin or bagged. Potted or bagged soils are best placed with well-drained, humus-rich loam or sandy loam, and they should be irrigated immediately after transplanting to establish roots. Due to root damage during transplantation, in order to adjust the body's water balance and reduce evaporation, the seedlings need to be picked up or picked. When the temperature is between 20°C and 30°C, the branches and leaves grow faster. The soil should always be kept moist to apply fertilizer once per month. Later, with the growth of seedlings, in order to promote dwarfing and fullness of the plants, it is necessary to carry out repeated toppings. During the growth process, the long branches may be thinned, and the styling may be required for styling. At the same time, the dry branches, old branches, dense branches, leggy branches, disease branches, and pest branches are cut off in time to improve the ventilation and light transmission conditions. After the flower is cut, remove the stumps to reduce nutrient consumption and promote flowering again. During the growing season, sufficient light should be given to control the moisture. In summer, the leaves should be sprayed with water to reduce the temperature. Diligently plough weeds to improve soil air conditions. During the flower bud period, it is necessary to dilute the thin-phase fertilizer, and it is also possible to take the fertilizer from outside the roots, ie, foliar dressing, and pay attention to the management of N, P and K fertilizers. After each bud removal, it is necessary to pour enough water. After one week, light fertilizer and water can be applied, and appropriate P and K fertilizers can be added to promote the flowering of new shoots. Pay more attention to phosphorus and potassium fertilizers at the seedling stage, and apply thin fertilizers during flower buds, and you can also use foliar fertilizer. Adult plants may be given 2 additional phosphate fertilizers during flowering. Prune after flowering to control shoot sprawl. When the temperature in winter is lower than 0°C, the plants are likely to produce defoliation. If the temperature is low for a long time, it will easily cause dry and dead in the aboveground parts. Therefore, in the southern open field planting or northern pot should pay attention to insulation in winter to ensure that plants safely overwinter.
Reproduction Management Techniques and Methods of Jade Leaf Golden Flower
Breeding mainly based on cuttings. In spring, select annual, vigorous and vigorous twigs, cut the length of cuttings 8-12cm and cut the lower end into 45-degree angles, and soak the bottom of the cuttings in low-concentration potassium permanganate solution for 1 hour to 2 hours before cutting. In the permeability of water permeability, good river sand or perlite, the cutting depth should be 1/2 of the length of the cutting, and the water should be irrigated once after being inserted. In future management, care should be taken to shade and maintain air humidity, which is generally 80% to 90%. When spraying, water should be sprayed to the foliage and the surrounding space in time. After 10 to 15 days, it can take root and survive.
