Problems solved by technology

However, due to drought, water shortage, strong light and hot weather in the ecologically fragile areas represented by dry-hot valleys, and the best time for grafting emblica from March to April coincides with the extreme drought and high temperature season in dry-hot valleys, traditional grafting methods cannot guarantee The humidity required for grafting emblica seedlings, there is no corresponding means of disease and insect pest control, and the management of adult plants is complicated. Therefore, the traditional grafting method makes the grafting survival rate of emblica seedlings in dry and hot valleys low, which limits the preservation and expansion of excellent germplasm resources of emblica emblica. Multiplication and production

Embodiment 1

[0033] Embodiment 1: the implementation steps of the present invention

[0034] (1) Selection of grafting time

[0035] Grafting should be carried out in mid-March to mid-April every spring when the average daily temperature reaches above 25°C.

[0036] (2) Selection of scion and rootstock

[0037] The scion adopts the fruiting mother branch of the excellent emblica variety, and the rootstock is ≥ 1 year old emblica seedlings that need to be improved. The diameter of the selected fruiting mother branch and emblica seedlings are both 0.8-1.0 cm. After the mature plants do not need to wipe the buds, It is convenient to manage after choosing such a rootstock to graft and survive.

[0038] (3) Carry out scion treatment liquid immersion and wax seal embedding process to scion

[0039] Cut the fruiting mother branch of the excellent emblica variety into 5-8cm from the top of the bud eye, and ensure that each branch has 1-2 full bud eyes. Prepare multivitamin 1%-3%, antiviral bac...

Abstract

The invention discloses a method for increasing the grafting survival rate of phyllanthus emblica seedlings in a dry-hot valley region. The grafting method specifically comprises steps as follows: (1)selection of grafting time; (2) selection of stock and scion; (3) scion treatment; (4) grafting; (5) management after bud grafting. According to the method, the grafting survival rate of the phyllanthus emblica seedlings is effectively increased by four links including optimization of the optimum time and stock form for bud grafting, optimization of scion and wax-sealed embedding treatment, optimization of a leaf-unfolding type bud grafting technology and management after grafting. By means of the seedling grafting method, later management is simple, the disease and pest damage resistance isimproved, the bud grafting survival rate of the phyllanthus emblica seedlings is higher than or equal to 95%, and the method is very suitable for grafting of the phyllanthus emblica seedlings in the drought and high-temperature dry-hot valley region.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for improving the grafted survival rate of emblica seedlings in dry-hot valley areas. Background technique [0002] The dry-hot valley is a unique ecosystem in Southwest my country. Its unique topography, monsoon, foehn and other factors have prepared sufficient light and heat resources for the development of characteristic agricultural production in this region. At the same time, these factors have also created ecological problems such as regional drought and low rainfall, soil and vegetation degradation. According to statistics, the dry-hot valley has an average annual rainfall of 667mm, with distinct dry and wet seasons, and the rainfall is concentrated from June to October. The K value is 1.5-2.8, therefore, the dry-hot valley region has typical climatic elements of drought and high temperature. [0003] Emlical emblica, commonly known as Yunnan olive, is...
