Nowadays, many farmers are using hormones to make their crops grow better. So, how should agricultural hormones be used?
Choose the appropriate agricultural hormone and its concentration. If you want to ripen the fruit, you should choose ethephon; canola. Rice, soybeans, peanuts. Sweet potatoes and other crops are prosperous and prosperous. It is advisable to choose a multi-effect cockroach or enestroconazole. When spraying, the concentration should be moderate. For example, 2, 4, D, 2 to 3 parts per million, sprayed in the cotton bud period, can effectively prevent the buds from falling off; and when using a concentration of 5 to 1000 parts per million It will make some dicots necrotic, but not harmful to monocots. Multi-effect å“© application in dry rice breeding, due to the impact of climate, the spraying concentration should not exceed 200 parts per million; used in late rice breeding, the concentration can be increased to 300 parts per million. The agricultural hormone is determined according to the time of the drug and the object of use. For example, gibberellin is applied before the tillering stage of rice, and it has the effect of promoting tillering. It is applied at the stage of tillering and at the end of tillering, but it has an inhibitory effect on tillering.
Some agricultural hormones are very sensitive to temperature and can only be applied in the morning, evening or cloudy days, if applied under hot days. It not only reduces the effect or has no effect, but also causes phytotoxicity to crops, resulting in reduced production. When adding pesticides, fertilizers and other substances to agricultural hormones, it is necessary to prevent precipitation. The method for separating the reaction layer from other pesticides and fertilizers is to mix the agricultural hormones with the pesticides or fertilizers in the same container and make a solution. If there is no turbidity, precipitation and bubbles, it indicates that the phenomenon occurs. Can be mixed.
