[0044] Cross breeding of Lagerstroemiafauriei (Lagerstroemiafauriei) and Lagerstroemia (indicaxfauriei) ‘Tuscarora’)

[0045] (1) Cross-breeding with Lagerstroemia fuchii (♀)×Lagerstroemia speciosa (♂);

[0046] Pest control: From June 15th to 30th, 2012, during the budding period of Lagerstroemia fowleri, the flowering branches of Lagerstroemia fowleri were sprayed with medicine to prevent insects from laying eggs in the buds, and 50ml of methamidophos was used to spray 20kg of water , 2 times a week, 4 sprays in total;

[0047] (2) Flower thinning: On July 5, 2012, each flower branch of Lagerstroemia fowles was retained with the strongest 3-4 branches, the two side flower buds were removed from each branch, and the largest flower bud in the middle was retained, and each flower branch was finally retained twice 10 flower buds that bloom daily, then spray 1000ppm of NAA to the entire flower branch to prevent new branches from sprouting at the cut and form secondary flowering;
