Embodiment 1

[0023] A special disease prevention 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.

[0024] The preparation method of the special disease-preventing composition for rice comprises the following steps:

[0025] (1) Pyrethrum is dried and pulverized, 3 parts by weight of pyrethrum is added with a mass concentration of 60% ethanol solution, extracted in a water bath at 70 degrees Celsius for 2 hours, filtered, and the filtrate is concentrated to 1 / 2 of the initial volume, Add allicin therein, then stir well to obtain material 1;

[0026] (2) Add methylisothiazolinone to distilled water with a weight ratio of 2 times to prepare a solution, then add the solution to material 1, and use a high-speed shearing machine to cut into a mixed solution to obtain a special disease-prevention product for rice combination.

[0027] A special ecological fertilizer for rice, its ...

Embodiment 2

[0029] 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.

[0030] Others are the same as in Example 1.

Embodiment 3

[0032] A special disease prevention composition for rice, the raw material composition and parts by weight are as follows: 1 part of pyrethrum extract, 3 parts of allicin, and 3 parts of methylisothiazolinone.

[0033] Others are the same as in Example 1.

Abstract

The invention relates to a special disease-preventing composition for paddy rice, which is prepared from the following materials in parts by weight: 1 to 5 parts of pyrethrum extract, 1 to 3 parts ofallicin and 1 to 3 parts of methylisothiazolinone. By preparing the disease-preventing composition for paddy rice from the pyrethrum extract, allicin and methylisothiazolinone and adding the special disease-preventing composition for paddy rice into an ecological fertilizer for paddy rice growing, and the ecological fertilizer can remarkably reduce the incidence of diseases, such as yellow rice borer disease, leaf folder disease and rice false smut, when applied to paddy rice growing, thus remarkably increasing the acre yield of paddy rice fields.

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...
