Problems solved by technology

[0004] In order to solve the problem of low survival rate of existing Yunnan olives in summer grafting, the present invention proposes a method for grafting Yunnan olives. The grafting method not only helps reduce the grafting time by selecting the grafting time of Yunnan olives in summer after the rain and clear weather. and it is not prone to mildew, and the use of wild Yunnan olives as rootstocks improves the survival rate of grafted Yunnan olives

Embodiment 1

[0019] Natural conditions of the test site

[0020] The test site is located in the Germplasm Resource Garden of Amla and Tamarind of the Institute of Ecological Agriculture, Institute of Ecological Agriculture, Yunnan Academy of Agricultural Sciences, Yuanmou County, Jinsha River dry-hot valley area. It is a typical dry-hot monsoon climate with an altitude of 1100m. The average temperature is 21.9°C, the extreme high temperature is 42°C, and the extreme low temperature is -0.1°C; the annual sunshine hours are 2670.4h; the annual average rainfall is 616.7mm, the annual evaporation is 6.4 times the rainfall, and the annual average relative humidity is 53.0%. Gentle slope platform. This region has wide distribution, large area and rich genetic diversity of wild emblica in this area, which is one of the best areas for collection, preservation and research of emblica resources.

Embodiment 2

[0031] In the experiment of grafting survival rate, the control group chose artificial Yunnan olive as the rootstock, and the grafting time was carried out in the summer of 2013 in hot weather (there was no rain for at least 3 days before grafting);

[0032] The grafting was carried out immediately; the survival rate was counted after 40 days of grafting, and the specific results were as follows:

[0033] Table 1 Survey of grafting survival rate

[0034] grafting method

[0035] As can be seen from Table 1, the grafting survival rate of olives using the grafting method of the present invention is significantly higher than that of the experimental group. During the experiment, it was found that the grafted olives of the present invention did not rot at the grafting place. In the control group experiment After 2 days of grafting, individual Yunnan olives were found to be rotten at the grafting site.

Abstract

The invention provides a grafting method for phyllanthus emblica. The method comprises the following steps: step a, selecting wild phyllanthus emblica as a rootstock; step b, obtaining a scion; and step c, taking the rootstock and the scion in the summer and the time that the sun shines again after the rain, performing joint, and performing binding by using a membrane. According to the grafting method provided by the invention, grafting time of the summer phyllanthus emblica is selected at the time that the sun shines again after the rain, so that reduction of problems when grafting is performed is facilitated, and mildewing is not easy to have; and the wild phyllanthus emblica is selected as the rootstock, so that a grafting survival rate of the phyllanthus emblica is improved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, and in particular relates to a Yunnan olive grafting method. Background technique [0002] Emblica (phyllansthus emblica) is a small tree of the Euphorbiaceae Phyllanthus genus, commonly known as olive, Yunnan olive, etc., which originated in the tropical region of southeastern Asia. The distribution of emblica covers a wide area of ​​70°-122° E, 1°-29° N, from the Himalayas to Sri Lanka, the Straits of Malacca, and tropical and subtropical regions in southern China. Wild emblica resources in Yunnan Province are very rich. Compared with other growing areas in the country, it has the characteristics of relatively high distribution altitude and large distribution area. Part of the river system is in the dry-hot valley region, which is located in the subtropical evergreen broad-leaved forest and tropical grassland area south of the Hengduan Mountains (south of 27° 40′ N). Due to the un...
