Embodiment 1

[0023] A method for preparing a special disease-preventing composition for rice, the raw material composition and parts by weight are: 3 parts of pyrethrum extract, 2 parts of allicin, and 2 parts of methylisothiazolinone; the preparation method comprises the following steps:

[0024] (1) Dry and pulverize pyrethrum, add 3 parts by weight of ethanol solution with a mass concentration of 60% per part by weight of pyrethrum, extract in a water bath at 70 degrees Celsius for 2 hours, filter, and concentrate the filtrate to 1 / 2 of the initial volume, Add allicin therein, then stir well to obtain material 1;

[0025] (2) Add methylisothiazolinone to 2 times the weight ratio of distilled water to prepare a solution, then add the solution to material 1, and use a high-speed shearing machine to cut into a mixed solution, so as to obtain a rice special disease prevention combination.

[0026] A special ecological fertilizer for rice, its raw materials include by weight: 15 parts of co...

Embodiment 2

[0028] A special disease prevention composition for rice, the raw material composition and parts by weight are: 5 parts of pyrethrum extract, 1 part of allicin, and 1 part of methylisothiazolinone.

[0029] Others are the same as in Example 1.

Embodiment 3

[0031] A special disease prevention composition for rice, the raw material composition and parts by weight are: 1 part of pyrethrum extract, 3 parts of allicin, and 3 parts of methylisothiazolinone.

[0032] Others are the same as in Example 1.

Abstract

The invention relates to a preparation method of a special paddy rice disease control composition, which is composed of following raw materials in parts by weight: 1 to 5 parts of pyrethrum extract, 1to 3 parts of garlicin, and 1 to 3 parts of methyl isothiazolinone. The special paddy rice disease control composition, which is prepared from pyrethrum extract, garlicin, and methyl isothiazolinone,is added into a paddy rice organic fertilizer; can obviously reduce the happening rate of diseases such as diseases caused by tryporyza incertulas, diseases caused by leaf folders, false smut, and the like, and thus prominently increases the acre yield of paddy rice.

Description

technical field [0001] The invention belongs to the field of agricultural planting fertilizers, in particular to a special disease-preventing composition for rice. Background technique [0002] The macronutrients nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth, and fertilizers containing nitrogen, phosphorus, and potassium need to be used to make up for it. In the micronutrient elements, except chlorine, which is not lacking in the soil, other nutrients need to be applied with trace element fertilizers. Fertilizers are generally mostly inorganic compounds, and only urea is an organic compound. Any chemical fertilizer that contains only one nutrient element that can indicate the content is called a unit fertilizer, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc. Any chemical fertilizer that contains two or more of the three nutritional elements nitrogen, phosphorus, and potassium and whose content c...
