Complex fertilizer for increasing oil tea yield

Abstract

The invention discloses a complex fertilizer for increasing oil tea yield. The complex fertilizer comprises the following raw materials in parts by weight: 70-80 parts of a main material, 30-50 partsof fermented castor seed oil, 10-20 parts of soybean meal, 4-12 parts of diatomite, 4-10 parts of radish sprout, 6-12 parts of coconut shell flour, 4-12 parts of oat bran, 1-2 parts of trace element,2-4 parts of pectin, 2-8 parts of vermiculite powder, 1-8 parts of coal slag, and 1-3 parts of perlite; and the main material comprises the following components in parts by weight: 50-65 parts of a composite nitrogenous fertilizer, 4-18 parts of a calcium magnesium phosphate fertilizer, and 2-8 parts of potassium nitrate. A method for preparing the composite nitrogenous fertilizer comprises the following steps: calcining Chinese medical stone powder, under a stirring state, adding ammonium hydroxide, then placing the materials in a polyvinyl alcohol aqueous solution, uniformly stirring the materials, then adding urea and carboxymethylcellulose sodium, heating the materials and stirring the materials, and performing spray drying to obtain the composite nitrogenous fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer for improving the yield of camellia oleifera. Background technique [0002] Camellia oleifera is an oil species with high seed oil content and high production value in the Theaceae Camellia family. It is an important woody oil economic tree species in southern my country, also known as camellia oleifera or tea seed tree, and olives, palms, coconuts And known as the world's four largest woody oil tree species. [0003] Camellia oleifera plants are 4-6m high, with thick and lignified fruit petals, which contain seeds. Camellia oleifera has a well-developed root system, is resistant to barren soil, and can adapt to a wide range of growth. It can make full use of marginal land for growth, and it has both economic and ecological benefits. In recent years, major Camellia oleifera planting provinces in my country have successively expanded the planting area of ​...

[0003] Camellia oleifera plants are 4-6m high, with thick and lignified fruit petals, which contain seeds. Camellia oleifera has a well-developed root system, is resistant to barren soil, and can adapt to a wide range of growth. It can make full use of marginal land for growth, and it has both economic and ecological benefits. In recent years, major Camellia oleifera planting provinces in my country have successively expanded the planting area of ​​Camellia oleifera forests, but the fertilizers applied are still ordinary chemical fertilizers, resulting in serious soil compaction and obvious reduction in yield and quality, which urgently needs to be solved
