Embodiment 1

[0027] Embodiment 1: Rice

[0028] First, this powdery pesticide is evenly spread in the cultivated land that needs to be planted with rice, and the above-mentioned pesticide is spread in each mu of cultivated land as shown in Table 1. After the pesticide is sprayed, the cultivated land is irrigated to keep the soil humidity at 60%, and then according to the temperature The height is placed for more than 10 days.

Embodiment 2

[0031] Example 2: Pepper

[0032] First, the granular pesticide is evenly spread in the cultivated land that needs to be planted with capsicum. The amount of the above-mentioned pesticide in each mu of cultivated land is shown in Table 2. The cultivated land where the above-mentioned pesticide is applied is deeply plowed. Irrigate the cultivated land after deep plowing to keep the soil humidity at 60-85%, and place it for about 20 days according to the temperature.

Embodiment 3

[0035] Embodiment 3: watermelon

[0036] First, the granular pesticide is evenly spread on the cultivated land that needs to plant watermelons. The amount of the above-mentioned pesticide in each mu of cultivated land is shown in Table 3. The cultivated land after the above-mentioned pesticide is applied is deeply plowed. The depth of deep plowing is 20-40cm. The cultivated land is covered with plastic film, and the surrounding area of ​​the plastic film is sealed tightly with soil, and water is poured under the film to keep the soil humidity at 60-85%. After 15 days of airtight storage, the plastic film is removed, and it is planted after 2 days in the sun.

Abstract

The present invention relates to a pesticide, in particular, it relates to a pesticide for killing injurious germ and pest in soil, its preparation process and application method. Said pesticide contains (by wt%) 15-70% of calcium cyanamide, 10-75% of calcium oxide and the rest is impurity. Its preparation method includes the following steps: placing calcium carbide, calcium cyanamide and additive into a reaction furnace, introducing nitrogen gas at 1000-1100 deg.C to make azotizing reaction for 18-24 hr so as to obtain the invented finished product. Said pesticide can be used as fungicide, insecticide, weedicide, nematocide and plant growth regulator, etc.

Description

technical field [0001] The invention relates to a pesticide, in particular to a pesticide for killing harmful germs and pests in soil, a preparation process and a use method thereof. Background technique [0002] Currently commonly used pesticides are divided into fungicides, insecticides, herbicides, rodenticides, acaricides, nematocides and plant growth regulators according to the control objects, and the original drugs of the above-mentioned different types of pesticides generally cannot To be used directly, it must be processed and formulated into various types of preparations before it can be used. In this way, when farmers use pesticides, on the one hand, they must understand the nature and objects of pests and diseases, and choose corresponding pesticides. Bring a lot of inconvenience. For this reason, many scientific and technical personnel have been dreaming hard to find a broad-spectrum pesticide that can sterilize and kill insects, improve the quality of crops, ...
