Last Updated: 2024/11/05, The production of 1000 kg pepper requires 5.2kg of pure nitrogen, 1.2kg of phosphorus pentoxide and 6.5kg of potassium chloride. Before planting, 5000 kg of high-quality farm manure and 50 kg of phosphate fertilizer were applied per mu. The pepper began to be fertilized for the first time at the initial stage of expansion in order to promote fruit expansion. Apply 15-18 kg of pure nitrogen and 18-20 kg of phosphate fertilizer per mu.

Now it is the summer harvest season, and there is a bumper harvest of wheat. At the time of welcoming the bumper harvest, we remind farmers that they must do a good job in the prevention and control of herbicide damage to chili peppers. Chili peppers cultivated in bare land often suffer from herbicide damage caused by herbicide drift in neighboring corn fields. Especially in the case of low temperature, the drug damage can not be alleviated, seriously affecting the growth and development of transplanted pepper seedlings, and even make pepper seedlings suffer from fallen leaves, flowers, serious death and no harvest, pepper farmers can only hope that pepper sighs. In view of the herbicide damage to corn, the herbicide was selected for detoxification according to the symptoms of pepper leaves and growing points. 1. For the earlier drug damage, you can quickly spray the leaves of the affected crops with a large amount of water. As most pesticides are easy to reduce their efficacy in case of alkaline substances, an appropriate amount of 0.2% baking soda solution or 0.5% lime water can be added to the spraying water to wash or flush. two。 Apply quick-acting fertilizer quickly. On the crops with drug damage, quick-acting fertilizers such as urea should be applied quickly to increase nutrients, promote crop growth vitality and speed up crop recovery. 3. Spray medicine to relieve the damage. Spraying drugs that can alleviate the drug damage, such as brassine, indoleacetic acid, chloropyruron, compound nitrophenol sodium and so on, can significantly alleviate the drug damage of crops. 4. Can be used to protect 1 gram + spray Shibao (organic water-soluble fertilizer) or resurrected 1 gram + spray Shibao to 15 kilograms of water evenly sprayed on the leaf. It was sprayed once every 3 days for 2 times in a row. Note: all the above chemicals are hormone plant growth regulators, which should be sprayed according to the situation to prevent excessive growth.
