There are several methods for treating peanut seeds with pharmaceutical agents:
1. Seed dressing with herbs: use 50% carbendazim WP, 0.15-0.25 kg per 50 kg of seeds (0.075-0.125 kg according to the active ingredient), and mix the powder with 2.5-5 kg ​​of fine soil. Evenly, formulated into medicinal soil. Peanut seeds are washed with water first, then layered and mixed with the soil. Each peanut seed should be evenly stained with the soil, and the soil can be immediately planted after mixing the soil.
Second, the liquid seed dressing: use 50% carbendazim WP, 0.15-0.25 kg per 50 kg of peanut seeds, add 2 kg of water into a liquid, spray on the peanut seeds with a sprayer, so that each Peanut seeds are evenly dipped in the liquid and can be sown after drying.
3. Soaking seeds with chemical solution: use 50% carbendazim wettable powder, 0.15-0.25 kg per 50 kg of seeds, add 30 kg of clear water to prepare liquid medicine, soak peanut seeds 50 kg, cold soak for 24 hours, middle flip 2 - 3 times, soaked after soaking.
The above methods have an effect of controlling stem rot, blight, root rot more than 90%, and there is no significant difference in the effect of seed dressing and soaking, but considering the seed dressing method is simple and easy, or the seed dressing is it is good. The peanut leaves treated with the drug are dark green and grow vigorously, with an average yield increase of about 30%, some increase 50%, or even more than double, the minimum increase is about 10%, the fruit rate increases by 10-20%, and the increase in yield is related to the drug. The amount increases and increases, but when the amount of the drug (active ingredient) exceeds 1% of the seed, there is a phytotoxicity that affects emergence.
Although the treatment of peanut seeds with carbendazim has obvious disease-preventing and yield-increasing effects, this agent has no disease-preventing effect on peanut bacterial wilt. For the diseased plots where peanut seeds are not treated with carbendazim, 1000 times of the liquid medicine can be sprayed at the seedling stage if necessary, and the disease prevention effect is also over 90%, increasing yield by more than 10%, and rooting with 500 times of liquid medicine Certain effect.
Tubular waterproof lights are waterproof, corrosion-proof and dust-proof. The respirator design quickly balances the pressure difference between the inside and outside of the lamp to prevent water and dust from entering the inside of the lamp to ensure the normal operation of the lamp.
Compared with the traditional waterproof lamp, it is more convenient to install. It only needs to open the orange end cap of the Led Tube Light, thread the wires in, and connect the terminals.
Led Tube Light can not only be linkable in series but also Parallel Connection, as shown in the figure below.
There are two installation methods, one is a sling and the other is ceiling installation. There are two types of ceiling installations, one is fixed and cannot be moved, and the other can be rotated 180°.
IP66 LED Tri-proof Light has emergency and sensing functions, which is very suitable for parking lots, warehouses, basements, workshops, etc.
