What are the cultivation and maintenance of Lagerstroemia indica?

Lagerstroemia indica likes the dry growing environment, and the land requires high terrain, which is conducive to drainage and irrigation, loose and fertile soil and sufficient sunlight. Only good plots can cultivate high-quality seedlings.

2. Soil preparation

The fertility of nursery land directly determines the growth quality of seedlings. Before deep ploughing, 6-8 tons of agricultural fertilizers such as chicken manure, pig manure and cow dung should be applied per mu, and then plowed with tractors to a depth of 30 cm, preferably before winter, so that most pests can freeze to death. After soil preparation, the optimum width of the boundary is1.5m, depending on the local conditions. The target is flat, and large pieces of soil are broken and leveled. Irrigation canals should be left at the head of the boundary and drainage ditches should be left at the tail of the boundary. The height should be from beginning to end.

Step 3: sow.

The temperature is different all over the country, which is far from each other. It can be planted in most areas in spring, summer and autumn. Select excellent varieties, and soak Lagerstroemia indica seeds in clear water to accelerate germination 1 day before planting. Then plant it according to the row spacing of 30 cm and drill it. Similar to planting corn, the sowing depth is 1 cm, and the dosage per mu is 10~ 15 kg, which generally germinates in 10~ 15 days. Cover with moist straw or plastic film after planting.

4. Maintenance methods

When Lagerstroemia indica seedlings grow to 8~ 15 cm, the first thinning should be combined with weeding opportunity, mainly to remove piled seedlings, weak seedlings and seedlings with late germination, improve ventilation and light transmission conditions, and make the strong seedlings grow better and more symmetrical.

When the height of the seedlings is 25 ~ 30cm, the seedlings are thinned for the second time. At this time, according to the row spacing of 10cm, about 20000 seedlings are left per mu. June-August is the fast-growing period of Lagerstroemia indica. Combined with watering, apply 40 kilograms of three-element compound fertilizer of nitrogen, phosphorus and potassium per mu, so as to apply fertilizer less frequently and in three times. It rains for a long time and should be drained in time to prevent waterlogging.

Ziwei can live for a long time.

Lagerstroemia indica is very old, within the normal time range of 200 years.

Tropical areas are widely cultivated as garden ornamental trees and sometimes as bonsai. Lagerstroemia indica has high ornamental value and is easy to plant and manage.

In the garden, according to the local actual situation and the needs of landscaping, single planting, opposite planting, group planting, cluster planting and row planting can be used for scientific and artistic landscaping.
