Dimethoate, Omethoate: Kiwifruit is particularly sensitive and avoids it; it can produce obvious phytotoxicity to plum, cherry, flower peach, eucalyptus, stalked sea bream, apricot, pear, etc. It is also very harmful to the shrimp flower and coral flower of Jujube. If it is sprayed with dimethoate from June to October, it often causes the petals to be rolled up, and the leaves, inflorescences and small schools fall off and lose their ornamental value. In addition, music It also has a certain impact on melons. Therefore, it is not appropriate to use dimethoate and omethoate in the above ornamental plants.
Being enemies: Dichlorvos has obvious phytotoxicity to plum, cherry, peach, apricot, eucalyptus, 20th century pear, Jingbai pear and other ornamental plants. Usually, other types of pesticides should be used instead. Dichlorvos also has different degrees of phytotoxicity to rhododendrons, taro, kiwi, sorghum, walnuts and melons. When using pesticides to control pests of these plants, care should be taken to avoid unnecessary losses.
Trichlorfon: It has phytotoxic effects on cherry blossoms and plum blossoms.
Stone sulphur mixture: Stone sulphur mixture has phytotoxicity to plants such as peach, plum, plum, pear, etc. If stone sulphur mixture is used on these plants, it is best to spray in the deciduous season, not in the growing season or flowering period. Use; stone sulfur mixture has certain phytotoxicity to kiwi, grape, cucumber and legume flowers.
Killing pine: use the killing insects in the hot season, have serious phytotoxicity to the pomegranate, and have certain damage to the flowers of the cruciferous family.
Bordeaux mixture: sensitive to peach and plum in the growing season; when less than double, pear, apricot and persimmon are susceptible to phytotoxicity. When the amount is higher than that, the grape is susceptible to phytotoxicity.
Pine fat tableting agent: In the summer, the use of rosin mixture has obvious phytotoxicity to persimmon, and the spring and summer season has an adverse effect on citrus.
In order to prevent pesticides from causing phytotoxicity to many ornamental plants, one is to purposefully switch to other high-efficiency and non-toxic pesticides; the second is to minimize the use concentration; the third is not to spray under high temperature and high humidity conditions; in order to avoid losses, Also pay attention to the rational use of pesticides.
Led grow light provide the following value in the agricultural and horticultural industries:
1. Provide light: indoor grow lights can provide the light required by plants, especially in the indoor planting environment, which can make up for the lack of natural light. This is important for the agriculture and horticulture industry, as light is a key factor in plant photosynthesis, which promotes plant growth and development.
2. Control spectrum and photoperiod: grow lights led can adjust the color and intensity of light to meet the light needs of different plants at different growth stages. For example, during the germination and flowering of plants, providing the appropriate spectrum and photoperiod can promote plant growth and flower fruit production.
3. Increase yield and quality: The use of plant lights can extend the growth time of plants and improve the yield and quality of plants. By controlling light conditions, photosynthesis and nutrient absorption of plants can be promoted, thereby increasing crop yield and improving the quality of agricultural products.
4. Energy saving: Compared with traditional agricultural planting methods, Led grow lights can use light energy more effectively and reduce energy consumption. grow lights can provide suitable light according to the needs of plants and avoid waste of energy.
5. Expand the scope of planting: The use of plant lights can free the agricultural and horticultural industries from the limitations of the natural environment and can be planted indoors or in a soilless culture environment. This can expand the range of cultivation and increase the availability and diversity of agricultural products.
In short, growth lights can provide important value in the agricultural and horticultural industry, such as light, spectrum and photoperiod control, increase yield and quality, save energy and expand planting range.
