Abstract

The invention provides a lagerstroemia excelsa cultivation method. The lagerstroemia excelsa cultivation method comprises the steps that a field is prepared: seeds collected in the same year are sowed from November to December; when the seedling height is up to 2 cm, a compound fertilizer with the content greater than or equal to 50% is applied for one time, the fertilizer is applied once again when the seedling height is up to 20 cm, the fertilizer applying amounts of two times of fertilizer application are both 30-35 kg per mu; qualified strong seedlings are selected, seedling planting is performed, the compound fertilizer is applied in July of the first planting year for one time, the applying amount every time is 50 g/plant, the fertilizer is applied in March and July respectively for one time starting from the second planting year, and the applying amount every time is 100 g/plant. The lagerstroemia excelsa cultivation method adopting sowing while collecting has the advantages that newly-collected seeds are large in moisture content, sowing while collecting is beneficial to maintenance of the seed moisture content, the germination rate of the seeds is improved, a seedling growth cycle is increased, and the growth amount of annual seedlings is increased.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a cultivation method of Sichuan and Guizhou crape myrtle. Background technique [0002] Lagerstroemia excelsa is a rare deciduous tall tree in the genus Lagerstroemia (also known as Lagerstroemia) in the genus Lagerstroemia. It is unique to China and is a subtropical positive tree species. It has strong germination, light-loving, warm and humid climate, and strong cold resistance. , Drought and waterlogging, likes fertile, moist and well-drained sandy loam and calcareous soil. According to experiments, Sichuan-Guizhou Lagerstroemia can grow into trees on the slopes of limestone mountains, and has strong germination ability after felling. It is an excellent tree species for rocky desertification control. Chuanqian crape myrtle has a straight trunk, hard and fine material, fine structure, strong termite resistance, and is an excellent and precious timber tree species; the bark peel...
