Cultivation method for high yield of Camellia oleifera forest

Abstract

The invention discloses a cultivation method for high yield of a Camellia oleifera forest. The cultivation method comprises the steps of land selection and land preparation, seedling selection, afforestation and planting, young forest management, harvesting and the like. The Camellia oleifera cultivated with the method is characterized in that survival rate is high, forest establishment is fast, fruit bearing period is short, and fruit bearing only takes 3-4 years after seedling planting. In the formula of basic fertilizer, nitrogen plays an important role in promoting plant growth and development; phosphate of phosphorus pentoxide has an important effect on plant metabolism, and can promote the development of root systems, improve the absorptive capacity of plants from the soil, enhance the stress resistance of plants, and promote the development of plant flowers and fruits; potassium of potassium nitrate plays a good role in promoting the growth of buds, young leaves and root tips of plants, and can enhance the stress resistance of plants, reduce diseases, prevent branches from being dry, and promote overwintering. Cake fertilizer of organic fertilizer is high in nitrogen and phosphate content, complete in nutrient, and lasting in fertilizer effect, and can continuously supply nutrients for crop growth and development; humus fertilizer has the effects of improving soil structure, supplying crops with a variety of nutrients and stimulating crop growth.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for cultivating camellia oleifera for forest growth and high yield. Background technique [0002] Camellia spp. is a general term for oil species with high seed oil content and production value in the Theacae (Theacae) genus Camellia. It is an important woody edible oil plant in southern my country. It is closely related to olive, oil palm, coconut And known as the world's four largest woody oil tree species. Its main product, camellia oil, has unique flavor, rich nutrition, high content of unsaturated fatty acids, reasonable composition of fatty acids, does not contain erucic acid and cornic acid that are difficult for the human body to absorb, and does not contain cholesterol that can cause blood pressure to increase and cause arteriosclerosis. The ideal edible oil is the crown of all edible oils. Camellia oil and its by-products have multiple uses in industry,...

Problems solved by technology

[0003] At present, due to the influence of the continuation of history, the Camellia oleifera left in the forest usually grows in valleys. Relevant experts also investigate Camellia oleifera according to the actual growth environment of Camellia oleifera, but Camellia oleifera grown in valleys cannot be well received by sunlight. If the sunshine time is short, the growth and fruiting of camellia oleifera will not be good.

When cultivating camellia oleifera nowadays, it is also appropriate to choose a relatively damp environment in the forest. The seedlings selected for planting are usually seedlings or bare-rooted seedlings, and the fertilizer used is ordinary farmyard manure or commonly used organic fertilizers. The measures taken in the cultivation and management of camellia oleifera cannot promote the survival of camellia oleifera seedlings, and the survival rate of seedlings can only reach 60-70%. As a result, Camellia oleifera does not grow luxuriantly, the fruit bearing rate is low, and it takes as long as 6-8 years for the tea seedlings to bear fruit after planting, which will greatly affect the application and promotion of Camellia oleifera
