Problems solved by technology

[0003] Lagerstroemia can usually be propagated by sowing, cutting or branching. At present, seed propagation is the main method, but this method of propagation is not good for seedling emergence, and the overwintering damage is relatively large; while the operation of branching propagation is more cumbersome, and attention should also be paid to the growth of Lagerstroemia indica. trimming
However, the existing cutting technology is not systematic, the rooting rate is not high, and it is easy to get sick

Embodiment 1

[0022] A cutting method with high survival rate of Lagerstroemia indica, the specific method steps are as follows:

[0023] 1) Lagerstroemia has no strict requirements on the soil, but it is better to use deep, fertile and well-drained soil, which can be planted in mountains, slopes, and fields; after selecting the land according to the growth habits, the tillage depth is 20cm, combined with tillage every 667 square meters Rice is mixed with 1000-2000 kg of decomposed farm manure, mixed with 25 kg of superphosphate and 25 kg of cake fertilizer, and raked evenly to make a high border with a width of 150 cm and a height of 20 cm, with a border spacing of 30 cm;

[0024] 2) In March-April, select lignified crape myrtle strong branches for two years or more, and cut 6-10 cm trident branches with flat shears, and cut the bottom 0.4-0.6 cm from the intersection of the three branches. Cut the 2 secondary branches short on both sides, and cut the branches for later use;

[0025] 3) Put the ...

Abstract

The invention provides a high-survival-rate cutting method for oriental-red lagerstroemia indica. The method specifically comprises the steps that (1), a field is selected according to the growth habit of lagerstroemia indica, deeply ploughed for 20 cm, 1000-2000 kilograms of thoroughly decomposed farm manure is applied per 667 square meters of the field in the ploughing process, the field is raked finely and uniformly, and rectangular pieces are made at the distance of 30 cm; (2) between March and April, a strong lignified lagerstroemia indica branch with the age of two years or above is selected, a Y-shaped branch with the length of 6-10 centimeters is sheared off in a straight shearing mode, two subsidiary branch parts on the two sides are sheared shortly, and a cutting branch is obtained for use; (3) the sheared cutting branch is placed in disinfectant to be soaked for 2-3 hours and then taken out to drain water until no water drips off, a disinfection treatment agent is smeared on a cut, and the cut is protected against infection to increase the survival rate of the branch; (4) the root of the cutting branch is stained with nutrient slurry and inserted in one rectangular piece for cutting, the two subsidiary branch parts on the two sides are inserted in soil in the rectangular piece for cutting, and the main branch part on the upper portion is left; (5) fertilization is not applied from cutting to sprouting, and management is conducted through a conventional management method after sprouting.

Description

Technical field [0001] The invention relates to the technical field of tree cuttings, in particular to a cutting method with high survival rate of Lagerstroemia indica. Background technique [0002] Ziwei, also known as Hundred Days Red, Full House Red. Lagerstroemia is a dicotyledonous plant of the Lythrum family. Produced in southern Asia and northern Australia. It is distributed in East China, Central China, South China and Southwest China, and is widely cultivated everywhere. The crape myrtle tree has a beautiful posture, a smooth and clean trunk, and a gorgeous flower color; when it blooms, it is the season of little flowers in summer and autumn. The compliment "This flower is full of red flowers" is a good bonsai material for viewing flowers, stems and roots. It likes light and is slightly tolerant to shade; it likes warm weather, it likes fertile, moist and well-drained soil, it tolerates drought and is afraid of flooding. Strong budding, slow growth, long life, stron...
