It is inevitable to grow vegetables on the balcony, and pesticides can't be used at home. What should you do?

The bird guard team will share some agricultural knowledge with you today! Planting vegetables on the balcony not only has the function of providing edible vegetables, but also allows people to provide a leisure and entertainment activity after busy work. In the reinforced concrete city, you can go home and look at the green, which is very interesting. For families with children, planting vegetables on the balcony can also play the role of popular science, so that roots, stems and leaves are no longer boring knowledge points in textbooks.

But it is still difficult to grow vegetables on the balcony for technical requirements. Improper operation may lead to soil and water on the balcony at home. If pests occur, it is not easy to spray pesticides on the balcony at home, which may endanger the health of family members.

For the first step of pests, it is important to contain the breeding source, plant the soil and substrate of vegetables, and choose sterilized commercial soil to avoid pathogenic bacteria and eggs carried in the soil. And if you want to apply base fertilizer to vegetables, you must choose a thoroughly decomposed finished fertilizer. If there are pests on vegetables, control them as soon as possible. For carnivorous insects such as Pieris rapae, artificial capture can be used.

For other insects, physical control methods can be used. Using the yellowing characteristics of insects, a sticky stick was made by coating glue on a yellow wooden board, so that insects could stick to it. However, some pungent liquids can also be prepared for spraying, such as pepper water, garlic water, laundry detergent and so on. Remember to spray evenly on both sides when spraying. If there are too many pests, simple control methods can no longer be controlled, then it is best to remove these vegetables to avoid the rampant pests at home because of small losses.

Planting vegetables on the balcony is a green leisure activity, and pests are inevitable. You don't have to worry too much. Take the initiative to prevent it. This is also the fun of experiencing farming operations. If the children at home can participate, I believe they can gain a lot.

When the occurrence of pests is relatively light, it is not recommended to use chemicals. Although chemicals can control the number of pests in a short time after spraying, they will bring many negative effects when used. For example, when spraying, chemical molecules are atomized, which is easy for the sprayer to inhale, and the large dose will be life-threatening. Therefore, it is recommended that operators wear masks and gloves when spraying chemicals. When pests appear on vegetables grown on your balcony, the first suggestion is artificial prevention.

If the pests are small, you can wipe the leaves of plants with a rag dipped in water, and then you can make your own medicine. For example, mixing washing powder with water to make a solution, and then adding a drop of clear oil. The purpose of cleaning oil is to prolong the control effect and spray insects on plants. The laundry detergent made by this method can kill aphids, scale insects, red spiders, green thorn moths, butterflies, whiteflies and so on. And flower plants with tuberous roots (such as Paeonia lactiflora and Dahlia) or bulbs (such as Lily and Lycoris radiata) and fleshy roots. This method is also effective in preventing nematodes. In addition, soap liquid, tobacco liquid, garlic liquid and baking soda liquid all have effects on pests and are favored by people. The application principle of garlic liquid is that many insects have avoidance reaction to the pungent smell of garlic.
