Embodiment 1

[0015] First will contain the powdered pesticide that the calcium cyanamide of 70% and 10% calcium oxide and 10% impurity composition are evenly spread in the arable land that needs planting pickled mustard by weight percentage, 20kg of above-mentioned agricultural chemicals are sprinkled in every mu of arable land, Irrigate the cultivated land after spraying pesticides to keep the soil moisture at 60%, and then place it for 7-30 days according to the temperature.

[0016] On the basis of the steps in Example 1, the weight percentage concentration and application rate of pesticides were changed, and the results of controlling clubroot of mustard mustard were shown in Table 1.

Embodiment 2

[0018] First will contain the granular pesticide that the weight percent is 70% calcium cyanamide and 10% calcium oxide and the impurity composition of 10% evenly spread in the cultivated land that needs to plant pickled mustard, spread above-mentioned pesticide 20kg in every acre of cultivated land, Deeply plow the above-mentioned cultivated land sprayed with pesticides to a depth of 20-40cm, then irrigate the plowed cultivated land with water to keep the soil humidity at 60-85%, and place it for 7-30 days according to the temperature.

[0019] On the basis of the steps in Example 2, the results of controlling mustard clubroot by changing the weight percent concentration and application rate of pesticides are shown in Table 2.

Embodiment 3

[0021] First will contain the granular pesticide that the weight percent is 70% calcium cyanamide and 10% calcium oxide and the impurity composition of 10% evenly spread in the cultivated land that needs to plant pickled mustard, spread above-mentioned pesticide 20kg in every acre of cultivated land, Deep plow the cultivated land after the above-mentioned spraying of pesticides, the depth of deep plowing is 20-40cm, cover the cultivated land with mulch film, seal the surroundings of the mulch film tightly with soil, irrigate under the film to keep the soil humidity at 60-85%, and place it in an airtight place for 15 Days later, remove the mulch, dry for 2 days, and plant mustard.

[0022] On the basis of the steps in Example 1, the weight percent concentration and application rate of the pesticides were changed, and the results of controlling clubroot of mustard mustard were shown in Table 3.
