Growth regulators are the general term for substances that regulate the metabolism and growth of plants. The correct use of growth regulators can promote or inhibit the growth of peppers, increase their resistance to stress, increase the seed-setting rate, early harvest, significantly increase yield, improve quality, and increase yield. The correct use of growth regulators has a miraculous effect that is more effective than ordinary cultivation methods that enhance fertilizer and water management.
One, brassin. It is a new growth regulator with the strongest physiological activity. In the seedling, flowering and fruiting stages of pepper, 0.01-0.017 mg/kg is applied once every 15-20 days (5 grams of 0.1% of the original powder is dissolved in 55-60°C water, and 30-50 kg of water is added. Brassinolide, sprayed 4-5 times, can promote pepper growth, early flowering results, increase the number of results and fruit weight, delay plant senescence, extend the harvest period, increase production by 10% -40%. When peppers show mosaic virus disease, add 5 pieces of medical ribavirin and 5 grams of 0.1% of brassin in 30 kilograms of water, and spray the whole plant after mixing, once in 7-10 days, and spray 2-3 times. , virus symptoms will soon disappear.
2,920. That is, gibberellin can make plant cells grow and promote growth. After the planting of spring chillies and peppers, as the long-term long-term low-temperature growth is slow, the seedlings tend to be weak. Each 667 square meters (1 mu) is filled with 3-4 g of 9200 (first dissolved in white spirit) and 5 kg of compound fertilizer. Alum, can promote the rapid root growth of pepper seedlings, markedly effective in about 3 days. The use of 90% plus 0.3% urea at a concentration of 10 mg/kg (1 gram of raw flour plus 100 kilos of water) to spray the field hot pepper seedlings (growing vigorously without spraying) can promptly and significantly promote their growth.
Third, naphthalene acetic acid. The main physiological role is to promote rooting and prevent flowering. In the flowering period of pepper, with 50 mg/kg naphthylacetic acid sprayed, the fruit setting rate increased significantly, and the fruit growth accelerated, so that the early yield of pepper increased by 22.6%, and the total output increased by 20.4%. The spraying of pepper plants with 10 mg/kg naphthylacetic acid sprayed once every 10-15 days for a total of 3-4 sprays can promote its growth, significantly reduce viral diseases and other diseases, reduce flowering, accelerate fruit enlargement, and extend the growth period. Increase production and income.
Spraying chili peppers with 30-50 mg/kg of vermiculite also has a good effect of flower protection and fruit protection. However, the vermin can only be sprayed on the flower spray and cannot be sprayed on the whole plant, otherwise it will cause phytotoxicity.
