Isoproturon will reduce the anti-freezing ability of wheat seedlings. In the short-term, the wheat seedlings will be frozen in the short-term frosty weather, and there will be “frozen poisoningâ€. Generally speaking, the average daily temperature will be frosted at 4~5°C. If this weather occurs within half a month after the application of isoproturon, it may cause phytotoxicity to wheat, and the wheat seedlings may have leaf chlorosis and growth inhibition. phenomenon.
After the application of isoproturon, the wheat field in the case of freezing damage caused by low temperature, if the field wheat seedlings are less damaged, only the leaves appear yellow and so on, there is no dead seedlings, and then the wheat seedlings can gradually return to normal growth, with little effect on the yield. If the damage is serious, but there are still more wheat seedlings that have not died in the field (more than 100,000 total stems per acre in the field), do not easily replant.
Spraying foliar fertilizer such as potassium dihydrogen phosphate or humate on wheat seedlings subjected to freezing phytotoxicity is conducive to promoting recovery of wheat seedlings. In addition, low temperature occurs frequently in winter, and measures should be taken to prevent freezing and seedlings, such as covering crop straw and applying organic fertilizer. Watering before the low temperature can increase the soil heat capacity, bridge the soil joints, and protect the seedlings from freezing.

When choosing a solar Ptz camera, the battery capacity is important
The battery capacity of the solar camera determines how long the camera can run without sunlight. The battery of the best solar safety camera can provide power for at least 12 hours, even when the sun is not big, and some models can run for 3 days on battery power. If you live in an area where there is a lot of sunshine all year round, the solar monitoring battery can only work continuously for one night. Long life rechargeable batteries are essential if you live in a place that is not exposed to sunlight for part of the year.
Whether solar monitoring is compatible with smart home Monitoring integrated with smart home systems allows users to view security videos from their smart displays and smart TVs.
