Embodiment 1
[0032] S1. Cultivate Quercus variabilis seedlings
[0033] Sterilize the yellow heart soil and peat with carbendazim, and put them in pots at a volume ratio of 2:1; water-select the seeds of cork oak to remove hollow, pest-damaged seeds, and soak them in 0.5% carbendazim solution for 10-15 minutes The seeds of Quercus cork are the provenance of Quercus cork in Beijing; sowing in April, sowing the selected plump Quercus cork seeds horizontally to the depth of 5 cm in the potted substrate, and cultivating them in the greenhouse for 1 month, until they grow into uniform seedlings .
[0034] S2, preparation of biological fertilizer
[0035] Firstly, the fruiting body of puffball was collected from the chestnut plantation in Liuyang City, Hunan Province. The fruiting body of puffball was sterilized with 70% alcohol on the aseptic operation table, and the fruiting body was cut longitudinally with a scalpel, and the tissue pieces the size of soybean grains were picked , inoculate i...

Abstract
The invention discloses a method for cultivating mycorrhizal seedlings of Quercus variabilis. The method includes the following steps that (1) seedling cultivation is carried out, specifically, from March to April, disinfected Quercus variabilis seeds are selected and sown into a disinfected seedling cultivating medium to cultivate for 20-40 days to obtain Quercus variabilis seedlings; (2) fertilization is carried out, specifically, the obtained Quercus variabilis seedlings are planted in a sterilized culture medium, after the lateral roots of the variabilis seedlings are developed, a biological bacterial fertilizer is applied near the roots of the variabilis seedlings; and (3) seedling management is carried out, specifically, regular watering and weeding are carried out, and the Quercus variabilis seedlings with well-developed mycorrhiza are selected for field planting. The cultivating method enables the roots of the Quercus variabilis seedlings and fungus to form a symbiotic system,the contact area of the roots of the seedlings and soil is increased, the problem of underdeveloped roots of the Quercus variabilis seedlings is effectively solved, and the survival rate of the seedlings after transplantation can be improved.
Description
technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a method for cultivating mycorrhizal seedlings of Quercus cork. Background technique [0002] Cork oak (Quercus variabilis) is a deciduous tree of the genus Quercus in the Fagaceae family. It is a traditional economic forest tree species, water and soil conservation tree species and fireproof tree species in China. Its fruit is rich in starch and is also known as "woody food". The distribution of Quercus variabilis in my country is extremely wide. Its horizontal latitudinal distribution ranges from southern Liaoning in the north to the central part of Yunnan Province in the south. The upper limit of the distribution increases continuously from north to south. 2000 ~ 3000m distribution. The wood of cork oak is ring-porous wood, the sapwood is light yellow, the heartwood is light red, and the cork layer of the bark is developed. The main raw material of cork; the shel...
