Embodiment 1

[0022] On April 1, 2015, 30 1.5-meter-high seedlings with fast growth, strong, straight stems, and no pests and diseases were selected as rootstocks; branches were trimmed, dead branches, diseased branches, weak branches, and elongated branches were cut off. and cross branches; use a sharp tool to cut the roots and spray 0.01mol / L naphthalene acetic acid solution, wrap it with shade nets, and backfill the soil. On February 1, 2016, it was transplanted into the American planting bag. The cultivation medium was loam, pond mud, and peat soil. The volume ratio of loam, pond mud, and peat soil was 1:1:1, and watered with 0.01mol / L Naphthalene acetic acid solution. On April 1, 2016, 1-year-old lignified, 5cm-long, 0.5cm-thick double-petaled crape myrtle branches were selected as scions. Lagerstroemia indica only keeps the trunk as the rootstock, and grafts are carried out as required. Careful management after grafting, strengthen water and fertilizer management and pest control. ...

Embodiment 2

[0024] On May 1, 2015, 10 large-flowered crape myrtle plants with a diameter of breast height of 3 cm were selected as rootstocks with fast growth, robustness, straight stem shape, and no pests and diseases; pruned branches, cut off dead branches, diseased branches, weak branches, leggy branches and Cross branches; use sharp tools to cut roots and spray 0.01mol / L naphthalene acetic acid solution, wrap with shade nets, and backfill with soil. On February 1, 2016, it was transplanted into the American planting bag. The cultivation medium was loam, pond mud, and peat soil. The volume ratio of loam, pond mud, and peat soil was 1:1:1, and watered with 0.01mol / L Naphthalene acetic acid solution. On May 1, 2016, select 1-year-old lignified, 6cm long, 0.8cm thick double-petaled crape myrtle branches as the scion and cut off 1 / 2 of the leaves, and put the cut part of the scion in 800 times chlorothalonil liquid Dip it for 10 minutes, keep 5 branches of each Lagerstroemia grandiflorum ...

Embodiment 3

[0026] On June 1, 2015, 10 Lagerstroemia grandiflora with a diameter of breast height of 5 cm were selected as rootstocks with fast growth, robustness, straight stem shape, and no pests and diseases; pruned branches, cut off dead branches, diseased branches, weak branches, elongated branches and Cross branches; use sharp tools to cut roots and spray 0.01mol / L naphthalene acetic acid solution, wrap with shade nets, and backfill with soil. On February 1, 2016, it was transplanted to the root control device. The cultivation substrate was loam, pond mud, and peat soil. The volume ratio of loam, pond mud, and peat soil was 1:1:1, and 0.01mol / L of Naphthalene acetic acid solution. On June 1, 2016, select 1-year-old lignified, 8cm-long, 1.0cm-thick double-petaled crape myrtle branches as the scion and cut off 2 / 3 of the leaves, and put the cut part of the scion in 800 times chlorothalonil liquid Dip it for 10 minutes, keep 8 branches of each Lagerstroemia indica as rootstock, and gr...

Abstract

The invention discloses a grafting method of double-petal lagerstroemia speciosa. A lagerstroemia speciosa seedling which is high in growth speed, strong, straight in truncal form and free of diseases and pests is selected as a stock, and a one-year branch which is full in bud, free of diseases and pests, semi-lignified and strong is selected as a scion branch; the incision of the scion is firstly selected to be soaked in 800-fold chlorothalonil for 5 min in April to June, then the incision is dripped in 800-fold thiediazole copper liquid for 10 min, the incision of the scion is attached to a formation layer of the stock, the scion and the stock are wrapped by a thin film, tied, sleeved with a plastic bag and tied on the portion below a grafting opening; the grafting wound can completely heal 1 month later, and the grafted branch grows normally; the plastic bag and the thin film are untied; the grafting survival rate is checked and counted. By means of the grafting method, the grafting survival rate can reach 80% or above, a large number of double-petal lagerstroemia speciosa saplings can be rapidly propagated, and excellent properties are kept.

Description

technical field [0001] The invention relates to a method for grafting crape myrtle with double petals. Background technique [0002] Lagerstroemi a speciosa (L.) Pers. is a large tree of the genus Lagerstroemi a speciosa (L.) Pers., which has the advantages of large and colorful flowers, long flowering period, rapid growth, and no serious pests and diseases. flowering tree species. Due to the large amount of flowering and seed setting and high seed germination rate, it is easy to sow and raise seedlings. [0003] Lagerstroemia indica is a natural mutant of Lagerstroemia indica. In addition to the advantages of Lagerstroemia indica, it also has the characteristics of petalized stamens and many petals. It is not easy to take root. How to breed Lagerstroemia indica with double petals is an urgent problem for the industry to solve. [0004] At present, there are only single-petal large-flowered crape myrtle in the market, and no double-petal large-flowered crape myrtle has be...
