Efficient cuttage method capable of increasing survival rate of crape myrtle

Abstract

The invention discloses an efficient cuttage method capable of increasing the survival rate of crape myrtle. The method comprises the following steps: selecting a piece of field having the characteristics of flat terrain, convenience in road passage, irrigation and drainage, and looseness and fertility of soil along with water conservation and fertilizer conservation for serving as a piece of cuttage field; covering the cuttage field with a layer of sandy soil with the thickness of 3-10 centimeters for serving as a cuttage substrate; selecting a Y-shaped branch of over 2 years for serving as a cuttage branch, cutting at 0.2-1 centimeter away from the juncture of three branches at the bottom, leaving a longer major branch in the middle of the upper part, and cutting two secondary branches on both sides; inserting the Y-shaped cuttage branch into the cuttage substrate, inserting the two secondary branches on both sides into the cuttage substrate, leaving the major branch on the upper part, controlling the temperature at 15-25 DEG C during cuttage and keeping the moisture of the cuttage substrate at 15-25 percent; after germination, trimming the branches, and only keeping the major branch; not fertilizing from cuttage to germination, keeping the soil moisture at 15-25 percent, and keeping the temperature at 15-25 DEG C; during 7-15 days after germination, applying 500 kilograms of farmyard manure per mu, and performing management according to the conventional management method at subsequent growing periods.

Description

technical field [0001] The invention relates to the technical field of cuttings, in particular to a high-efficiency cutting method capable of improving the survival rate of crape myrtle. Background technique [0002] Lagerstroemia indica, also known as hundred day red, full house red. It is a dicotyledonous plant of the genus Lagerstroemia in the genus Lagerstroemia. Native to southern Asia and northern Australia. It is distributed in East China, Central China, South China and Southwest China, and is widely cultivated in various places. The crape myrtle tree is beautiful, the trunk is smooth and clean, and the flowers are gorgeous; when it blooms, it is the season of few flowers in summer and autumn, and the flowering period is extremely long, from June to September, so it is called "hundred-day red" and "midsummer green cover eyes". , This bounty is full of praise" is a good bonsai material for viewing flowers, viewing stems, and viewing roots. It likes light, slightly ...

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, and the rooting rate is not high. Especially in summer, it is easy to die from dehydration, or cause losses due to various reasons such as excessive humidity, insufficient ventilation, or wilting due to lack of water.
