The so-called who can carry the boat can also overturn the boat. In addition to removing weeds, the herbicide can also inhibit the growth of crops. Some herbicides should be used with caution and disabled. Let's take a look at the small series of pesticide nets . . Quick kill You can't grow any crops except for rice within 300 days after the quick killing of cockroach (dicloquine). You can't grow eggplant or tobacco within 12 months. You can't grow tomatoes or carrots within 2 years. In addition, umbelliferous crops such as carrots, celery, and cilantro are very sensitive to fast killing, and it is not possible to water the above crops with the water of the paddy fields that have been killed. Chlorsulfuron It has a long retention period in the soil, and it is not suitable to grow beets, rice, potatoes, melons, vegetables, sorghum and cotton. Sike (methadazine, oxalofenone) test reported that 20,000 to 1120 grams of active ingredient per hectare (15 acres) can be used to grow alfalfa, asparagus, wheat, barley, corn, potato, sweet potato after 4 months. , sugar cane, soybean, grass pasture; rice and cotton can be planted after 8 months, and other crops other than roots can be planted after 12 months. At present, it is generally recommended that the dosage of Sike is 210-560 grams per hectare of active ingredient, which is generally safe for the crop after harvest. Guangmingling According to reports, per turf (15 acres) with active ingredients 560 ~ 1400 grams of chlorhexidine, 9 months after application can be planted rice, cotton, corn, pepper, tobacco, cucurbit crops, all crops can be planted after 16 months . At present, it is generally recommended that the amount of chlorhexidine used in combination with other drugs has no effect on the sorghum crop, but heavy spray has a slight effect on wheat. The main features of the T8 lamp include: Herb Led Grow Light,Herb Grow Light,Indoor Herb Grow Light,Indoor Herb Light Shenzhen Pvison Technology Co., Ltd. , https://www.pvisunggrowlight.com
1. High luminous efficiency: T8 lamps use phosphors and electronic ballasts, which can provide high brightness and high luminous efficiency lighting effect, providing sufficient light for plants.
2. Energy saving and environmental protection: Compared with traditional incandescent lamps, T8 lamps have a higher energy efficiency ratio and longer service life, which can save energy and reduce carbon emissions.
3. Good spectrum: T8 lamps can provide spectra of different wavelengths according to the growth needs of plants, such as blue, red and full spectrum, which is conducive to the growth and reproduction of plants.
4. Easy installation: The T8 lamp adopts the common G13 interface, which can be directly installed on the T8 lamp holder without additional modification and installation work.
In the field of plant planting, T8 lamps are widely used in the growth lighting of indoor flowers, vegetables, fruits, lawns and potted plants. It can provide sufficient light intensity and appropriate spectrum, promote plant photosynthesis and growth and development, improve yield and quality.
It should be noted that different plants have different needs for light, so when choosing T8 lamps, it is necessary to choose the appropriate spectrum and light intensity according to the growth stage and type of plants. At the same time, reasonable lamp layout and use time are also key factors to ensure good plant growth.
After 3 kinds of herbicides, the crops should be used with caution.
