Abstract
The invention discloses a honey pomelo sustained and controlled release decrement set meal fertilizer which is prepared from a tip-prompting flower-strengthening fertilizer, a fruit-stabilizing fruit-strengthening fertilizer and a harvested fruit preservation fertilizer according to a mass ratio of 91:120:523. The tip-prompting flower-strengthening fertilizer is prepared from a 42% sulfur-containing sustained and controlled release composite fertilizer, a 46% nitro-compound fertilizer and borax according to a mass ratio of 77:22:1; the fruit-stabilizing fruit-strengthening fertilizer is prepared from a 45% sulfur-containing sustained and controlled release composite fertilizer, 46% nitro-compound fertilizer, a 58% water-soluble fertilizer and magnesium sulfate according to a mass ratio of 66.7:16.7:8.3:8.3; the harvested fruit preservation fertilizer is prepared from a 45% sulfur-based compound fertilizer, borax, zinc sulfate, a commercial organic fertilizer and calcium superphosphate according to a mass ratio of 15.3:0.19:0.38:76.48:7.65. The set meal fertilizer can simultaneously provide a sustained and controlled release nitrogen source and a rapid-acting nitrogen source, and meets requirements of honey pomelo for nutriment in different periods; yield of the honey pomelo can be improved, the benefits are increased, fertilizer application times are reduced, and content of vitamin C in the honey pomelo and a sugar-acid ratio are improved.
Description
technical field [0001] The invention belongs to the field of preparation of slow-controlled-release fertilizers, in particular to a slow-controlled-release and weight-reduced package fertilizer for honey pomelo and a fertilization method thereof. Background technique [0002] Honey pomelo is the economic crop with the largest planting area in southern Fujian Province. The planting area in Pinghe County, Zhangzhou City alone has exceeded 800,000 mu. Honey pomelo is a perennial economic crop with a large amount of fertilization. Each fruit pomelo needs to be applied with 6-8kg of high-concentration compound fertilizer every year. At present, the fertilization of honey pomelo is mainly in accordance with the traditional fertilization method, urea and compound fertilizer are applied as basal fertilizer and top-dressing in the later stage. The compound fertilizer formula is generally simple, and the number of top dressings reaches 5-6 times, which is not only inconsistent with th...
