Anonymous users2024-02-15If you want to grow sweet potatoes, it is best to use pesticides to kill insects first. After harvesting the peanuts at home, turn the soil over and over on a sunny day, so that the top is empty and the bottom is empty. When ploughing the ground, I found a lot of underground pests such as ground tigers and grubs.
50 kg of quicklime was sprinkled per acre. Sweet potato seedlings are not harmed by underground pests at the beginning of growth. With the growth of sweet potatoes, the stems and leaves are more and more vigorous, which provides a place for the rapid reproduction of underground pests.
Only by taking the method of trapping to get rid of insects, the adult tigers are trapped, that is, 3 parts of brown sugar, 4 parts of rice vinegar, 1 part of liquor, 2 parts of water plus 1% of trichlorfon, stir evenly, pour it into the rice bowl, pour about 15 bowls per mu.

Use less unrotted organic fertilizer, which contains insect eggs.

How to do it in case of an insect outbreak: Chlorpyrifos or rain on the roots!
For ground tigers, mole crickets can be used to use its aromatic properties to fry about 5 kilograms of soybean cake, or wheat bran, or corn crush, and then mix well with 30 times the liquid kilogram of 90% trichlorfon, add an appropriate amount of water and mix the tide for the degree, sprinkle about kilograms per mu, and sprinkle about kilograms in the windless and sultry evening.

2. Selection of location: To prevent insects from growing in the process of planting sweet potatoes, it is recommended to implement the method of water and drought when selecting the cultivation area. In the first half of the year, rice and other crops are planted, and in the second half of the year, sweet potatoes are planted.
Replacing wet and dry crops every six months is more conducive to preventing insect pests.
3. Insecticides: Sweet potato insects are generally underground insects. There is the best spraying Lesben solvent on the market, which has a strong ability to remove underground insects.
The self-prepared superphosphate is mixed with dry and pure plant ash to leach the clarification solution, tea bran aqueous solution, etc., which is also very strong in preventing underground insects.
4. Install insecticidal lamps: For flying insects on the ground, when planting sweet potatoes in a large area, install several frequency-vibration insect-trapping lamps in the greenhouse to trap and kill insect pests. Dead flying insect carcasses can be cleaned up or allowed to blend into the soil on their own, increasing the protein content of the soil.
5. Group cultivation seedlings: If conditions permit, sweet potatoes can be cultivated by propagation of group culture seedlings. Although the operation method of group cultivation of fierce seedlings is relatively complicated, the ability of this planting method to prevent seedling diseases and insect pests is very strong, and it can effectively reduce the situation of sweet potato insects.
6. In the process of daily breeding of sweet potatoes, the problem of field drainage should be dealt with, so as not to cause water accumulation in rainy days, affect the growth of crops, and also induce pests and diseases, so that sweet potatoes have sufficient light time, shouting can enhance its disease resistance, which is very beneficial to plant growth.
You can put some pesticides in the land, so that the insects will not dare to eat them, which is very good and makes the sweet potatoes grow better.
In rural areas, sweet potatoes are generally put in the morning when cooking or steaming rice on the stove, and compared with sweet sweet potatoes, I prefer Jiangxi's local starchy white potatoes, which are glutinous and delicious, and can also be made into potato flour and vermicelli.

In the sweet potato root expansion period, the roots can be irrigated with 20 times the tobacco leaf leaching solution, 3500 kg per mu, and the roots can be irrigated about 3 times in a row. This liquid is pure plant and will not cause any pesticide damage to sweet potatoes, so you can use it with confidence. It can also be applied in the sweet potato planting stage, potato tuber expansion stage or larval peak stage after the spore infects the grub larvae, making it lethal, and there is still a certain control effect after three years of fungus soil application.
