High-yield cultivation techniques of Camellia oleifera forest
Camellia oleifera as a unique woody edible oil tree species,has both economic value and ecological maintenance functions.The techniques for high-yield cultivation of Camellia oleifera forests combined its biological characteristics were systematically explored,including selection of afforestation sites,superior varieties,and others.Camellia oleifera trees are 2-8 meters tall,with spherical or nearly spherical fruits that generally mature in autumn.The key points of high-yield cultivation techniques include selecting areas with an altitude of 100-500 meters,sufficient sunlight,and slopes below 25 degrees for planting;scientifically apply nitrogen,phosphorus,and potassium fertilizers based on the nutrient status of the soil and the growth needs of plants to improve the soil;select varieties with larger fruits,thinner skin,and higher seed and oil extraction rates;choose strong seedlings that are one or two years old,ensuring their good growth and strong stress resistance;excavate planting holes and adopt reasonable methods for seedling planting;reasonably irrigate and reasonably fertilize oil tea trees based on their age,soil texture,and local climate conditions;after the oil tea is harvested and before the new shoots sprout in spring,remove diseased and weak branches in a timely manner;adopt agricultural,biological,and chemical control measures to timely prevent and control diseases such as anthracnose and soft rot,as well as pests such as Biston marginata and Euproctis pseudoconspersa;when the fruit is 80%to 90%ripe,it should be harvested and processed promptly to prevent spoilage.These technological lare interrelated and together form a complete,efficient,and sustainable high-yield cultivation techniques system for Camellia oleifera,provide references for the efficient development of Camellia oleifera and its related industries.
