Embodiment 1

[0019] The herbicide of the present invention is prepared by using the following raw materials in weight proportions: 0.1 parts of isopropylamine, 5 parts of menaphthylamine, 30 parts of sodium hexametaphosphate, 5 parts of cyclohexam, 10 parts of 0.1% potassium dihydrogen phosphate, and 25 parts of white vinegar , 10 parts of pumpkin leaves, 15 parts of pothos, the preparation method of which comprises the following steps:

[0020] (1) Mix and grind pumpkin leaves and pothos to fine powder, add white vinegar, heat and stir for 20 minutes at 40°C, cool and filter;

[0021] (2) Add cyclohexamin to 0.1% potassium dihydrogen phosphate solution and heat, the heating temperature is 18°C, fully stir until it dissolves completely, let stand and cool, then add menaphthylamine and heat, the heating temperature is 23°C, fully stir until Dissolve completely, cool down;

[0022] (3) Add isopropylamine to the liquid obtained in step (1), shake it fully, then mix it with the liquid obtaine...

Embodiment 2

[0024] The herbicide of the present invention is prepared from the following raw materials in weight ratio: 5 parts of isopropylamine, 10 parts of menaphthylamine, 35 parts of sodium hexametaphosphate, 10 parts of cyclohexam, 15 parts of 0.1% potassium dihydrogen phosphate, and 30 parts of white vinegar , 20 parts of pumpkin leaves, 20 parts of pothos, its preparation method is with embodiment 1.

experiment example

[0026] Test method: use the herbicide as the treatment area, do not do the treatment as the control area, spray the herbicide and do not treat the angelica of the same area respectively, and take 3 points immediately after spraying the herbicide 20 days, each point 0.3 square meters, record the number of plants of various weeds respectively, and by: weeding effect=(number of weeds in control area-number of weeds in experimental area) / number of weeds in control area, calculate the control effect of various common weeds, The test results are shown in Table 1:

[0027] Table 1

[0028]

[0029] As can be seen from the table: when the herbicide prepared in Example 1 is used in an amount of 80 grams / mu, the weeding effect reaches about 90%, and when the amount is 100 grams / mu, the weeding effect reaches about 92%, and when the amount is 120 grams / mu, The weeding effect reaches about 95%; according to the herbicide prepared in Example 2, when the consumption is 80 grams / mu, the ...
