Special tomato liquid fertilizer for comprehensive prevention and control of diseases and insect pests and preparation method of special tomato liquid fertilizer

Abstract

The invention provides special tomato liquid fertilizer for comprehensive prevention and control of diseases and insect pests and a preparation method of the special tomato liquid fertilizer. A formula is prepared from the components: 10 to 20 parts of a urea ammonium nitrate solution, 5 to 10 parts of an ammonium polyphosphate solution, 10 to 20 parts of potassium fertilizer, 1 to 5 parts of medium elements, 5 to 10 parts of humic acid, 0.5 to 2 parts of microelements, 20 to 40 parts of water, 1 to 5 parts of a homemade biogenic pesticide extracting solution, 1 to 2 parts of a soil conditioner and 1 to 2 parts of a natural surfactant, wherein the homemade biogenic pesticide extracting solution is obtained by mixing pyrethrum, azadirachta indica and radix sophorae flavescentis according to a ratio and extracting with water; the preparation method comprises the following steps: mixing the prepared urea ammonium nitrate solution and the prepared ammonium polyphosphate solution into a mixing groove according to a formula ratio and adding other metered materials into the mixing groove; uniformly mixing and dissolving; filtering to prepare the liquid fertilizer. The liquid fertilizer provided by the invention has the advantages of high efficiency, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special liquid fertilizer for tomato used for comprehensive control of diseases and insect pests and a preparation method thereof. Background technique [0002] Tomato, alias tomato, foreign persimmon, ancient name June persimmon, good news three yuan. The fruit is rich in nutrients and has a special flavor. Can be eaten raw, cooked, processed into ketchup, juice, or canned whole. Tomato is one of the most commonly cultivated fruit vegetables in the world. Its root system is developed and its regeneration ability is strong. Many root groups are distributed in the soil layer of 30-50cm. According to the principle of nutrient balance, plants can grow and develop normally only after the absorption of various nutrients reaches a physiological balance. Once the nutrient ratio is out of balance, the metabolism of the plant will be destroyed accordingly and there will be phy...

Problems solved by technology

According to the report of Chinese patent document CN 201510640183.8, vitamin C and B were dissolved in water, vitamin E was dissolved in absolute ethanol, and the three liquids were mixed, added to MS liquid medium, and cultivated in a shaking table at room temperature for 30 days to obtain a biological fertilizer for tomato. This method has the disadvantage that the business elements in the fertilizer are not rich, and cannot meet the nutritional needs of tomatoes throughout the growth process.

There is also the Chinese patent document CN201410125337.5 reporting that the formula is calculated by weight, according to urea, calcium nitrate, potassium dihydrogen phosphate, magnesium sulfate, iron sulfate, borax, manganese sulfate, sodium molybdate, zinc sulfate, copper sulfate, ethephon, Mix rotenone and ytterbium nitrate evenly to get special fertilizer for tomato. This patent has insufficient organic matter content. Extensive use of inorganic fertilizers will reduce the organic matter content in the soil, and the soil is easy to harden. Moreover, due to the comprehensive influence of fertilizer properties and soil environmental conditions, etc., Low fertilizer use efficiency is a common problem in the application of inorganic fertilizers. Excessive application of inorganic fertilizers leads to soil compaction and reduced soil permeability.
