Problems solved by technology

Therefore, in production, oak afforestation is generally harvested and sown in autumn, and the seeds will start to germinate when they encounter suitable water and air conditions. However, the success rate of afforestation is low. The main reason is that small animals such as squirrels and mice in the forest eat acorns. , handling and storage are strong
However, planting seedlings for afforestation or young replanting, seedlings have a slow seedling stage, require high water conditions, and the cost of afforestation is also high

Embodiment 1

[0048] 1. Seed Collection

[0049] In October of that year, mature oak seeds were collected in the cork oak forest in Lushan County, Henan Province. The seeds that are plump and free from diseases and insect pests are selected as experimental materials.

[0050] 2. Seed insecticide

[0051] Before storing the seeds in sand, use 0.5% BHC powder to dress the seeds at a weight ratio of 1:100, pile up the seeds, and cover them with pure sand. The thickness of the covering should be such that the seeds cannot be seen. Insecticide stays on for 24 hours. Weevils and their eggs, the main pests of oak seeds, are killed with poison. Disinfection of the seeds before sand storage is carried out afterwards.

[0052] 3. Seed and substrate disinfection

[0053] Soak the dewormed oak seeds with 1-3% potassium permanganate aqueous solution for 1 hour. to disinfect the seeds.

[0054] Equally, the matrix (table 1) that is used to store seeds in sand is stirred evenly with 1~3% aqueous po...

Embodiment 2

[0091] Arborvitae lower replanting

[0092] 1. Planting method

[0093] There are 3 working plots on the same hillside, and the vertical contour divides each working plot into 4 5m*20m small plots. The matrix treatment in each small plot is the same, and there are 4 treatments in each plot. They are respectively: nutrient soil + oil pine soil, nutrient soil + understory soil, soil plus bacteria, no-treated control ( image 3 ).

[0094] Replanting in gaps under arborvitae. Cluster-like replanting, 4 plants in clusters, 3 clusters in clusters ( Figure 4 ).

[0095] 2. Replanting method

[0096] The planting pit is 40cm×40cm×40cm. When digging the pit, the humus layer, surface soil and raw soil are placed separately. Before placing the seedlings, first return the surface soil and humus, then return to the substrate, and finally return to the raw soil. Thumb and forefinger together lightly compact the soil, and if there are sprouts, lightly compact the soil around the di...

Abstract

The invention provides a method for quickly forming a forest of Quercus variabilis in an artificial forest of Arborvitae, and relates to the technical field of artificial forestation. The invention starts from four technical subsystems of the whole process from the cork quercus seed collection to the formation of mixed saplings, the processing time, the growth state, the nutrient matrix, the symbiotic species and the growth environment. Each subsystem has an established goal. By forming the synergistic development of the elements in the subsystem, it can make a unique contribution to the overall goal and ensure the rapid and high-quality growth of cork oak from seed to sapling. The method of the invention can quickly and high-quality realize the mixed pattern of the regeneration layer of Quercus arborvitae, and the indicators such as germination rate, survival rate, leaf quantity and growth quantity are all higher than the traditional sowing afforestation mode by more than 3 times.

Description

technical field [0001] The invention belongs to the technical field of artificial afforestation, and in particular relates to a method for rapidly forming a forest of Quercus variabilis in an artificial forest of oriental cypress. Background technique [0002] There are widely arborvitae plantations formed by multi-year afforestation since the 1960s in Beijing and North China. Due to the inherent characteristics of coniferous plantations and the cross-influence of various natural and human disturbance factors, these plantations generally show problems such as slow tree growth, stunted or degraded soil development, and poor stand and tree health. [0003] North China has four distinct seasons and sufficient sunlight; winter is cold and dry and long, summer is relatively high temperature and precipitation is relatively high, and spring and autumn are short. Water shortages and frequent drought disasters make it one of the most important climate-vulnerable regions in the world...
