Abstract

The invention discloses special organic/inorganic compound fertilizer for earthworm dung-sourced citrus and a production method thereof. The special organic/inorganic compound fertilizer is prepared from the following raw materials by weight percent: 60 to 70 percent of earthworm dung, 5 to 10 percent of earthworm amino acid nutritional stock solution and 20 to 35 percent of inorganic fertilizer.The earthworm dung, the earthworm amino acid nutritional stock solution and the inorganic fertilizer are uniformly mixed to obtain organic/inorganic compound fertilizer. By utilizing the earthworm dung, the soil environment of a citrus orchard can be effectively improved, the clay is loosened, the pH of the soil is neutral, the nutrition absorption of the citrus tree can be facilitated, the resistance of the citrus tree for diseases and insect pests can be improved, the soil-borne diseases can be inhibited, and the quality of the oranges can be improved; by adopting an amino acid nutritional solution, the absorption and utilization of the citrus tree to medium and trace elements can be improved by virtue of a complexing effect; and by adopting the inorganic fertilizer, the insufficient part of nutritional elements in the organic raw material can be compensated, and the nutrition requirement of the citrus growth can be met.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a special organic-inorganic compound fertilizer derived from vermicompost for citrus and a preparation method thereof. Background technique [0002] Citrus is one of the most widely planted fruit trees in the world. my country has a long history of citrus cultivation. In 2014, the output of citrus in my country reached 3.49×10 7 t, the citrus planting area reached 2.52×10 7 hm 2 . Scientific and reasonable nutrient supply is one of the important links for high-yield and high-quality citrus. However, the management of nutrient resources in most orange orchards in my country is unreasonable. The nitrogen, phosphorus, potassium and their total application amount per ton of citrus fruit production in my country are 4.48, 15.85, 3.93 and 5.37 times of the required amount respectively. Excessive nutrient input leads to extremely low fertilizer utilization efficiency in orchard...
