Blueberry special fertilizer and preparation method thereof

Abstract

The invention discloses blueberry special fertilizer and a preparation method thereof; the granular blueberry special fertilizer is obtained mainly by crushing raw materials of organic materials, ammonium sulfate, ammonium dihydrogen phosphate, potassium sulfate, ferrous sulfate, and sulphur according to certain weight percents, screening, and performing mechanical granulation. The blueberry special fertilizer of the invention promotes the growth of blueberry, provides blueberry plants with a normal leaf color, strong branches, a high fruit-setting rate, and improved blueberry fruit quality, provides the possibility of large area planting of blueberry in our country, and fills the gap of domestic blueberry fertilizer.

Description

technical field

[0001] The invention relates to a special fertilizer for blueberries, which relates to the field of compound fertilizers in fruit tree or flower production, in particular to a special fertilizer for blueberries and a preparation method thereof. Background technique

[0002] Blueberry (Blueberry) scientific name Vaccinium spp, also known as bilberry, blueberry, is a perennial deciduous or evergreen shrub in Rhododendronaceae Vaccinium. There are 3 major commercial cultivation types: highbush blueberry, rabbit eye blueberry, and lowbush blueberry. Blueberry fruit has a unique flavor and rich nutrition, and is known as the "king of berries". Blueberries are rich in anthocyanins, low in sugar, low in fat, and have strong antioxidant capacity. Because of their unique nutritional value and health care effects, blueberries are listed as one of the top five health foods for human beings by the International Food and Agriculture Organization, and are listed as the thi...
