Problems solved by technology

The traditional direct-seeding production does not undergo anti-rodent feeding treatment, and the preservation rate of seeds in the planting hole is low, and the seed germination rate is often only about 50%, which limits the large-scale direct-seeding afforestation of cork oak

Embodiment 1

[0030] The direct seeding afforestation method of Quercus variabilis provided in the embodiment of the present invention includes the following steps:

[0031] 1) Seed collection and treatment: Collect mature Quercus variabilis seeds in autumn, and select seeds to keep the number of seeds at 260-300 seeds / kg. Soak the cork oak seeds in warm water at 53°C for 15 minutes, remove the soaked cork oak seeds, and spread them out to dry in the shade in a place not exposed to direct sunlight.

[0032] 2) Coating production: The following components are composed according to the weight component ratio, 5000 parts of soil dried and ground through a 2mm sieve, 600 parts of dried chili powder, 400 parts of dried camphor powder, 400 parts of dried mint powder, and dried bay powder 400 parts and 200 parts of dried pepper powder are mixed and stirred uniformly to obtain a mixed powder; put the mixed powder into a plastic bucket, gradually add water and stir, the mixed material and water are compo...

Abstract

The invention discloses a direct seeding and afforestation method of cork oaks, which comprises the following steps of: soaking cork oak seeds with water for a period of time, taking out the cork oakseeds, and drying in the shade; mixing soil and powder with pungent smell, and uniformly stirring to obtain mixed powder; adding water into the mixed powder, and stirring to form a slurry-shaped lagging cover; placing the dried cork oaks seeds into the slurry-shaped lagging cover, and stirring uniformly; digging planting holes in a land for direct seeding, digging at least one sowing pit in each planting hole, sowing at least one seed coated with the lagging cover in each sowing pit, and covering with soil and pressing. According to the invention, sensitivity of rodents to the odor is fully utilized, the seed lagging cover is made of natural materials with pungent smell such as camphor powder, chilli powder and the like to reduce the feeding of rodents to the cork oak seeds in germinationperiod, and the preservation rate and germination rate of the seeds in the planting holes are increased.

Description

Technical field [0001] The invention relates to the technical field of forest seeds, in particular to a direct seeding afforestation method of cork oak preventing rodents from eating. Background technique [0002] Quercus variabilis (scientific name: Quercus variabilis Bl.) belongs to the order Fagaceae and belongs to the deciduous tree of the Fagaceae Quercus. It is an important timber species in China. Distributed in China's Liaoning, Hebei, Shanxi, Shaanxi, Gansu, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Taiwan, Henan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan and other provinces. North China is usually born on a sunny slope below 800 meters above sea level, and the southwest region can reach an altitude of 2000-3000 meters above sea level. [0003] At present, the common cultivation method of Cork oak is direct seeding afforestation. As the seeds of cork oak are commonly used food for rodents in autumn and winter, the prior art lacks anti-rodent f...
