Novel liquid fertilizer special for peanuts and applied to comprehensive prevention and control of plant diseases and insect pests, and preparation method thereof

Abstract

The invention provides a novel liquid fertilizer special for peanuts and applied to comprehensive prevention and control of plant diseases and insect pests, and a preparation method thereof. The formula is as follows: 10 to 20 parts of a urea ammonium nitrate solution, 10 to 20 parts of an ammonium polyphosphate solution, 5 to 10 parts of a potassium fertilizer, 1 to 5 parts of trace elements, 20 to 50 parts of water, 1 to 10 parts of a self-made plant pesticide extracting liquid, 1 to 5 parts of a soil conditioner, 1 to 5 parts of natural active organic materials and 1 to 2 parts of a natural surfactant, wherein the self-made plant pesticide extracting liquid is prepared by mixing red clover, folium artemisiae argyi, szechwan Chinaberry fruit, radix sophorae flavescentis and black false hellebore according to a ratio and performing lixiviation by using water. The preparation method comprises the following steps: adding the prepared urea-ammonium nitrate solution and the ammonium polyphosphate solution into a mixing groove according to the proportion, adding the above materials into the mixing groove, mixing, stirring, dissolving and filtering to prepare the novel liquid fertilizer. The liquid fertilizer provided by the invention is convenient to use, has good effects and is an environmentally-friendly liquid fertilizer.

Description

Technical field [0001] The invention belongs to the field of fertilizers, and specifically relates to a new type of special liquid compound fertilizer for peanuts that can be used for comprehensive prevention and control of diseases and insect pests and a preparation method thereof. Background technique [0002] Peanut is an annual herb with abundant nodules at its roots. The flowering and fruit period is generally 6-8 months. Peanuts need nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, zinc, manganese, copper, iron, boron, molybdenum and other essential nutrients during the growth process. At present, peanuts in China generally use conventional fertilizers and do not pay attention to the application of trace elements. In addition, the low fertilizer utilization rate results in the lack of trace elements such as molybdenum, iron, and boron in peanuts in our country. If molybdenum is lacking, the rhizobia loses the ability to fix nitrogen; iron-deficient peanuts canno...

Problems solved by technology

There is also patent CN201510467233.7 reporting multifunctional bio-organic liquid fertilizer and its production method. Plant pesticides and growth regulators are combined into liquid fertilizers. There is a lack of trace elements, resulting in insufficient peanut production. There are also direct addition of plant pesticides and growth regulators. These commercial preparations contain a large amount of organic solvents, polluting environment, and there is a risk of insufficient stability in water, delamination
