Embodiment 1

[0023] Raw materials required for the production of special fertilizer for drip irrigation during grape fruit expansion: 722.22 kg of potassium nitrate, 107.08 kg of monoammonium phosphate, 40.01 kg of urea, 124.798 kg of magnesium sulfate heptahydrate, 0.38 kg of boric acid, 3.69 kg of EDTA chelated iron, 0.21 EDTA chelated copper kg, 0.6 kg of EDTA chelated manganese, 0.002 kg of sodium molybdate, and 1.01 kg of EDTA chelated zinc. (In order to ensure the water solubility of the special fertilizer and reduce impurities as much as possible, the raw materials are all selected agricultural grade or industrial grade elemental fertilizer with impurity content below 2%).

[0024] Preparation:

[0025] In order to prevent the crystal water in magnesium sulfate heptahydrate from reorganizing and agglomerating the finished product due to repeated mechanical stirring, and to ensure that trace elements and other raw materials with a small amount of mixing are evenly mixed, the producti...

Abstract

The invention provides high concentration drip irrigation fertilizer exclusively used in the fruit enlargement period of grapes utilized in a drip irrigation system and a preparation method thereof. The main components of the drip irrigation fertilizer exclusively used in the fruit enlargement period of grapes are as follows (according to the parts by weight): 611-723 parts of potassium nitrate, 90-108 parts of monoammonium phosphate, 33-41 parts of urea, 124-256 parts of magnesium sulfate heptahydrate, 0.3-0.6 part of boric acid, 3.6-5.8 parts of EDTA chelated iron, 0.2-0.4 part of EDTA chelated copper, 0.6-1.0 part of chelated manganese, 0.002-0.004 part of sodium molybdate and 1.0-1.6 parts of EDTA chelated zinc. The drip irrigation exclusively used fertilizer has dramatic effects, canobviously improve the yield and quality of grapes, and can save fertilizer and improve efficiency. The drip irrigation exclusively used fertilizer combines the domestic all-pervading trend of the irrigation system and the main national principle of saving fertilizer and improving efficiency and has quite wide market prospect.

Description

technical field [0001] The invention relates to a special fertilizer for drip irrigation and full nutrition for agricultural production, in particular to a special high-concentration drip irrigation fertilizer for grape fruit expansion period and a preparation method thereof. Background technique [0002] The fruit of grapes (Vitis vinifera L.) of the genus Vitaceae (Vitaceae). It is a deciduous vine and one of the "four major fruit trees" in the world. Because grapes are widely used and have high economic value. In recent years, my country's grape planting industry has developed rapidly. According to statistics, in 2007 China's grape receiving area ranked fifth in the world, and its total output ranked third. However, there is a clear gap between the output per unit and the world's advanced level, ranking only 20th in the world. The production methods in most of China's grape producing areas are still relatively traditional, and the methods of hand-poured and furrow irr...
