Abstract

The invention discloses a compound liquid fertilizer for promoting early maturity of citruses and a preparation method of the compound liquid fertilizer. The compound liquid fertilizer is prepared from 600mg/L of potassium nitrate, 300mg/L of ammonium sulfate, 500mg/L of monopotassium phosphate, 200mg/L of magnesium sulfate, 100mg/L of calcium chloride, 10-20mg/L of ammonium molybdate, 0.2mg/L ofcopper sulfate, 50-100mg/L of urea, 50-100mg/L of cobalt dichloride, 50-100mg/L of niacin, 5-10mg/L of folic acid, 5-10mg/L of amino acid, 5-10mg/L of a plant growth regulator, 50-100mg/L of choline chloride and 30-50mg/L of an organic chelating agent. By adoption of a reasonable raw material ratio, the compound liquid fertilizer is capable of providing all essential nutrients to growth of citrustrees, high in permeability and solubility and capable of promoting vigorous growth of the citrus trees to realize early maturity.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and relates to a compound liquid fertilizer for promoting early ripening of citrus and a preparation method thereof. Background technique [0002] Citrus is a small evergreen tree that usually blooms in spring and matures in November-December. In my country, the medium-maturing varieties of citrus that mature in November and December account for more than 85%, and the early-maturing and extra-early-maturing varieties that mature before the end of October only account for about 10%. In order to make citrus enter the market earlier, the main measure is to develop early-maturing varieties, but the number of early-maturing varieties is currently small. If corresponding cultivation measures can be taken to make citrus mature earlier, it will help improve economic benefits. Obviously, the cost of cultivating early-maturing varieties is higher, and the cultivation period is longer. Fertilizer...
