Abstract

The invention discloses a high tower granulation biological compound fertilizer with a function of preventing and controlling pests and diseases and a preparation method thereof, wherein the high tower granulation biological compound fertilizer is prepared from the following raw materials in parts by weight: 92-94 parts of a granular core fertilizer, 2-3 parts of a urea formaldehyde resin coatingagent, and 4-7 parts of a compound microbial inoculant. The high tower granulation biological compound fertilizer with the function of preventing and controlling pests and diseases is reasonable in ingredient collocation; through the synergy of various nutrient elements, the high tower granulation biological compound fertilizer promotes the balanced reasonable absorption of crops in nutrients, activates soil nutrients, improves a soil structure, reduces soil bulk density, effectively prevents and controls pathogenic bacteria in soil, strongly promotes rooting, inhibits soil degradation, improves the fertilizer and water retention capacity of the soil, and has a good role in prevention and control of nematodes and underground pests, and is of great significance to realize sustainable development of agriculture.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a high-tower granulated biological compound fertilizer with the function of preventing and controlling pests and diseases and a preparation method thereof. Background technique [0002] my country is a country with a large population and a large agriculture. It uses 7% of the world's land to feed 22% of the world's population. Food issues are always a major issue related to the national economy and people's livelihood. my country has 2 billion mu of arable land and needs 150 million tons of fertilizers annually. It is the world's largest importer of fertilizers and producer of nitrogen fertilizers. Even so, the amount of chemical fertilizers still cannot meet the needs of agricultural development. The reason is that the key problem is that the utilization rate of chemical fertilizers is too low. According to investigations, the utilization rate of my country's chemical ferti...
