How are the seeds of Lagerstroemia indica spread?

Common propagation method include sowing and cuttage,

Among them, the cutting method is better, the survival rate of cutting is higher than that of sowing, the plants bloom earlier, grow faster and the seedling yield is higher. A large number of healthy and tidy seedlings can be obtained at one time by sowing and propagating Lagerstroemia indica. The process of sowing and propagation includes seed collection, soil preparation and bed making, seed germination accelerating treatment, sowing time and sowing method. Lagerstroemia indica has a long flowering period, from June to September, flowers and fruits coexist, and the results are orderly. From September to165438+1October, when the capsule turns from green to brown and some individuals begin to crack, the fruit sequence can be picked and the mature fruit sequence at the base can be harvested. Osmanthus fragrans stored until March of the following year has strong adaptability to the environment, drought resistance and cold resistance, and has no strict requirements on soil, but it grows best when planted in deep, fertile and loose sandy soil with acidic soil. First, hoe the seedbed soil, and treat the sowing ditch according to the specifications of 20-2~3cm wide and 2-3 cm deep. Generally, Lagerstroemia indica is planted in March and April, and the seeds are sown in the open air, and the seeds are evenly scattered on the flat seedbed. Sprinkle about 2-3 capsules every 3-4cm. After sowing, cover with fine soil about 2 cm thick. After about 10~ 14 days, most seeds germinated. Make sure the soil moisture after coming out. After the seedlings grow two pairs of true leaves, in order to ensure that the seedlings have enough growth space and nutrient area, we can choose to interplant the nursery after the rain, so that the air between the seedlings can circulate and the sunshine is sufficient. During the growing period, we should strengthen management, topdressing thin fertilizer 2-3 times in June-July, preventing drought in summer, watering frequently, and keeping the nursery moist, but remember not to overdo it. The height of seedlings can reach 50 ~ 70 cm in winter. Plants that grow well can bloom in the same year. After defoliation in winter, trim the side branches and open the flower branches in time. Transplanting in early spring of the following year.
