Abstract

The invention discloses a drip irrigation fertilizer for promoting the increase of the oil content of oil-tea camellia fruits. The fertilizer comprises 10.35 wt% of urea, 38.09 wt% of diammonium phosphate, 51.18 wt% of potassium sulfate, 0.05 wt% of sodium tetraborate, 0.19 wt% of zinc sulfate and 0.05 wt% of magnesium sulfate. The drip irrigation fertilizer can solves the problems of low oil content, low fruit cracking rate and low seed yield of fruits in the key period of oil conversion of the oil-tea camellia fruits, and can effectively promote the increase of the oil content of oil-tea camellia fruits and promote the development of oil-tea camellia fruits in order to effectively increase the oil content of fruits.

Description

technical field [0001] The invention relates to a drip irrigation fertilizer preparation technology for increasing the oil content of camellia oleifera fruit, and belongs to the technical field of high-yield cultivation of camellia oleifera. Background technique [0002] Camellia ( Camellia oleifera Abel.) is the main woody oil tree species in southern my country. The pursuit of stable and high yield is the goal of Camellia oleifera planting, and the efficient management of Camellia oleifera fruit growth and development period is the premise of stable and high yield of Camellia oleifera. Camellia oleifera fruit transformation peak period is from late August to mid-September. The nutrient status at this stage is related to the growth and development of the fruit and the production and accumulation of photosynthetic products. Increase fruit weight and fresh seed rate to achieve the effect of maintaining continuous high yield of camellia oleifera. [0003] The fertilizers i...
