Acetic acid manufacturing method for manufacturing acetic acid root, fruit fly control method for how to eliminate fruit flies

Do you know the manufacturing method of acetic acid? Do you know the law of fruit fly control? If not, let's take a look at it.

1. Manufacturing method of acetic acid

Purpose: soil irrigation has the effect of inhibiting nematodes, foliar spraying has fertilizer effect, and has the function of repellent and sterilization.

Materials: shrimp or crab shell powder, industrial research vinegar (using high concentration of acetic acid, about 10%, generally called 10 degrees; edible vinegar is 3-5 degrees.) , wood vinegar (materials to be sent for review), buckets.

Production method:

1.150g shrimp or crab shell powder + 1000c.c.~1500c.c. Industrial research vinegar. Mix evenly and soak to dissolve.

two。 Mix 1.30 liters of wood vinegar. Stir once a day and can be used in a week.

Note:

1. The solution will blister during production, so the bucket should be doubled.

two。 Spraying leafy vegetables should be used in seedlings or a long time before harvest, diluted by 300 times. Fruit trees are diluted with the same leafy vegetables.

Join the exhibition effect to make it more complete

Qidao acetic acid (diluted 500 times)

+ neem seed oil (diluted 500 times)

+ wood vinegar (diluted 300 times)

Note: Melia azedarach is wild in Taiwan, and November of the Chinese calendar is the peak period for its seed-bearing.

Note:

1. The use of all kinds of natural pesticides should depend on the reaction of leaves, adding or decreasing the concentration. But 250 times is the thickest bottom line.

two。 Qidao acetic acid should be kept in a cool place for a period of two weeks.

II. Prevention and control of fruit flies

l. Use a trap.

two。 The expired (cheaper) oasis guava juice is placed in the trap to attract fruit flies to enter, which can only enter but not out, resulting in suffocation or starvation. However, because the aroma of guava juice is only spread within 5 to 10 meters, so the number of hanging needs more, about one tree, and not in the same direction, it is better to hang in a staggered way.

1. About 200 hectares are needed.

3. It is said that due to the vigorous promotion of the Eastern Peasants' Association this year, the problem of fruit flies seems to have decreased significantly.

4. Prevention is better than cure, and you need prevention and treatment before it happens.
