Development Of Guangxi Camellia Infant Formula Fertilizer

Camellia Oleifera is an important Woody edible oil tree.Camellia in the South is generally planted in the soil is barren hills,and fertilization conditions and poor tree growth deficiency was severe, affect the normal growth and bearing oil tea tree body.Therefore, in view of characteristics of soils in different parts of the South was developed to fertilization technique on the nutrition diagnosis of nutrient complete sterilization and formulation science, insects, and other special fertilizer for tea, to promote oil-tea Camellia oleifera in good growth results, improving fertilizer use efficiency, increase resistance is important, improve the quality and yield of Camellia oleifera.This study combines the characteristics of young Camellia oleifera forests in Guangxi, to young Camellia oleifera as materials, using plant analysis, soil analysis methods, in the system of juvenile forest soil condition of oil-tea Camellia, Camellia leaves, plant growth, nutrient content and year cycle based on dynamic variation law of developed indicators of nutrition diagnosis of Guangxi young Camellia oleifera and recommended fertilizer programme.The main results are as follows:(1) the fertilizer effect of fertilization on the young plantation of Camellia oleifera is mainly to promote vegetative growth of young plantation, characterized by the increase in tree height, diameter, Crown diameter.By different formula fertilizer test, to N:P2O5:K2O= 16:6:8 the best, tree height, diameter and Crown width control improved, and 32.84%, and 28.13%, respectively.(2) fertilization on the young plantation of tree height, diameter, Crown diameter absolute growth impacts no significant difference, but for each fertilizer treatment relative to tree height, diameter, Crown diameter increment had significant effects.Comprehensive comparison, fertilizer for the promotion of 0.50kg/strains on the growth of tea-oil tree plantations works best.Different fertilization treatments on soil nutrient and fertilization on the young plantation of Camellia oleifera disproportionate in size, fertilizer for 0.50kg/best strain to raise tea plantation soil fertility.(3) the growth potential of young Camellia oleifera and its biomass accumulation was positively correlated, characterized by the increase in tree height, diameter, Crown diameter.Growing good tea their accumulated mainly in the aboveground part of tree biomass with poor growth potential is accumulated into the ground.Tea plantations each organ biomass in proportion of total plant biomass in order of size:trunk (35.01%)> main root (22.16%)> leaves (19.65%)> branches (16.9%)> lateral roots (6.27%).Nutrient accumulation in vegetative organs are:leaf (29.75 g/kg)> lateral roots (19.02 g/kg)> branches (17.11 g/kg)> main root (14.55 g/kg)> trunk (10.76 g/kg).Distribution of nutrient elements and the disproportionate relationship between the biomass of each organ. Size of nutrient content in different organs of young Camellia oleifera:nitrogen> potassium, calcium> magnesium> p> iron and manganese> zinc> boron> copper.Thus,young Camellia oleifera tree nitrogen and potassium and calcium absorption and accumulation of the highest fertilization on the young plantation of Camellia oleifera should pay attention to calcium fertilizer application,taking into account the combined application of trace elements.
