Problems solved by technology

Due to insufficient activity of foliar fertilizers and unstable irrigation water supply in some areas, the transpiration of tomato plants is weak, and the effective elements in fertilizers cannot reach the organs that need the elements with water, so it is often necessary to increase the amount of fertilizer application or Increase the frequency of fertilizer use to enhance the effect, which not only wastes fertilizer resources, but also destroys the ecological environment of farmland to a certain extent
So far, there is no report on the calcium-based compound foliar fertilizer for tomatoes developed by effective microbial technology

Abstract

The invention provides a special tomato leaf surface compound fertilizer which comprises mixed liquid fertilizer and an EM (Effective Microorganism) scale-up medium, wherein the mixed liquid fertilizer contains calcium chloride water solution, calcium nitrate water solution and potassium nitrate water solution, and the EM scale-up medium contains molasses, EM medium and water. The invention further provides a preparation method of the compound fertilizer. The compound fertilizer is simple in preparation technique and low in cost, effectively combines microorganism technology and compound fertilizer technology, effectively couples potassium nitrate, calcium chloride, calcium nitrate and other fertilizers, and performs fermentation treatment by taking EM as a carrier; on one hand, nutrition balance can be achieved, the growth and development of tomato plants can be promoted, and the tomato yield can be increased; on the other hand, the blossom-end rot disease attack rate of tomatoes can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a special foliage compound fertilizer for tomatoes, and also relates to a preparation method of the compound fertilizer. Background technique [0002] Tomato navel rot, also known as pedicle rot, is one of the most common diseases on tomatoes. Especially in coastal (river) sandy loam areas and drought years, the damage is serious. When the disease is severe, it often causes black spots and rot on the fruit, which directly affects the yield and quality. [0003] Tomato navel rot generally occurs when the fruit grows to the size of a walnut. Initially, water-soaked lesions appeared on the navel, and then gradually expanded, causing the top of the fruit to become sunken and brown. Lesions are usually 1-2 cm in diameter, and when severe, extend to half a fruit. When dry, the diseased part is leathery. When it encounters wet conditions, various mold layers grow o...
