Embodiment 1

[0012] A kind of special fertilizer for tomato fruit expansion stage, the weight ratio of raw materials is: 10 parts of urea, 11 parts of ammonium nitrate, 15 parts of ammonium phosphate, 20 parts of potassium nitrate, 15 parts of potassium dihydrogen phosphate; 3 parts of abamectin dregs, 3 parts of vermicompost; 0.1 part of borax; 3 parts of gypsum; 5 parts of attapulgite clay powder; 6 parts of forsterite; 0.1 part, 0.4 part of ammonium molybdate.

[0013] Abamectin dregs in the present embodiment is the filter residue produced by fermentation broth filtration after fermentation is completed in the process of preparing avermectin by fermentation. After testing, the total content of nitrogen, phosphorus and potassium in abamectin dregs reaches 5%-9%; the organic matter content (by dry weight) is over 54%.

[0014] The preparation process of the special fertilizer for the above-mentioned tomato swelling period is as follows:

[0015] (1) Take the above-mentioned raw materia...

Embodiment 2

[0023] A kind of special fertilizer for tomato fruit expansion stage, the weight ratio of raw materials is: 12 parts of urea, 10 parts of ammonium nitrate, 10 parts of ammonium phosphate, 30 parts of potassium nitrate, 10 parts of potassium dihydrogen phosphate; 6 parts of avermectin dregs, 1 part of vermicompost; 0.2 part of borax; 2 parts of gypsum; 10 parts of attapulgite clay powder; 5 parts of forsterite; 0.1 part of disodium edetate, 0.3 part of ferrous sulfate, 0.2 part of manganese sulfate, zinc sulfate 0.3 parts, 0.6 parts of ammonium molybdate.

[0024] Abamectin dregs and preparation method are the same as in Example 1.

[0025] Table 2 Effects of special fertilizers on tomato diseases and insect pests and yield during fruit expansion stage

[0026]

[0027] Table 2 shows that the special fertilizer for tomato fruit expansion can effectively kill bacteria and prevent diseases, and increase tomato yield.

Embodiment 3

[0029] A kind of special fertilizer for tomato fruit expansion period, the weight ratio of raw materials is: 15 parts of urea, 15 parts of ammonium nitrate, 13 parts of ammonium phosphate, 26 parts of potassium nitrate, 12 parts of potassium dihydrogen phosphate; 8 parts of abamectin dregs, 5 parts of vermicompost; 0.3 part of borax; 5 parts of gypsum; 8 parts of attapulgite clay powder; 8 parts of forsterite; 0.5 parts, 0.2 parts of ammonium molybdate.

[0030] Table 3 Effects of special fertilizers on tomato quality during tomato fruit expansion stage

[0031]

[0032] It can be seen from Table 3 that the special fertilizer for tomato fruit expansion significantly increased the content of soluble solids in the fruit, the reduced VC also increased, the sugar-acid ratio increased, and the tomato quality was better than ordinary compound fertilizers.

Abstract

The invention provides a special fertilizer used in a tomato fruit swelling period. The special fertilizer used in the tomato fruit swelling period can be used for regulating or improving a tomato strain growth process, so that the effects of increasing the yield and improving the quality are realized. The fertilizer used in the tomato fruit swelling period is prepared from the following raw materials in parts by weight: 10-15 parts of urea, 10-15 parts of ammonium nitrate, 10-15 parts of ammonium phosphate, 20-30 parts of potassium nitrate, 10-15 parts of monopotassium phosphate, 3-8 parts of abamectin decoction dreg, 1-5 parts of wormcast, 0.1-0.3 part of borax, 2-5 parts of gypsum, 5-10 parts of attapulgite powder, 5-8 parts of magnesium olivine, 0.1-0.5 part of ethylenediamine tetraacetic acid disodium, 0.2-0.3 part of ferrous sulphate, 0.2-0.5 part of manganese sulphate, 0.1-0.5 part of zinc sulphate and 0.2-0.6 part of ammonium molybdate.

Description

technical field [0001] The invention relates to a special fertilizer for tomato, in particular to a special fertilizer for tomato fruit expansion stage, which belongs to the field of fertilizer. Background technique [0002] Tomato fruit expansion period is a critical period for the formation of tomato yield and quality. Improper management during this period often results in small fruit, low yield, and many deformed fruits. Existing special fertilizer for tomato has: application number is 200810015500 disclosed a kind of tomato special-purpose fertilization, consists of 25-35 parts of urea, 8-20 parts of monoammonium phosphate, 35-45 parts of potassium sulfate, 15-25 parts of ammonium humate . Preparation method: The raw materials are respectively crushed to 150-200 mesh, mixed evenly according to the proportion, and finally measured and packaged to be the finished product. The application number is 20071011554, which discloses a special controlled release fertilizer for ...
