In recent years, with the development of the vegetable industry, the planting area of ​​peppers in Lulong County has increased year by year. Now that the peppers are in the fruiting period, the vegetable growers must strengthen the management of fertilizers and waters to ensure a bumper harvest.
Pepper has strict water requirements. It is neither drought nor odor resistant and prefers dry air conditions. When the pepper is flooded for several hours, it will die and die, so watering or draining conditions should be convenient. The root system of pepper is strict with oxygen, and it should be deep and fertile in the soil, rich in organic matter and good air permeability. Pepper grows with sufficient nitrogen, phosphorus, and potassium. Phosphorus plays an important role in the formation and development of flowers. Potassium is an essential element for fruit enlargement. Nitrogen, phosphorus, and potassium must be coordinated in production, and on the basis of sufficient base fertilizer, topdressing should be done well to increase yield and quality. .
First, fertilizer management
1. Chong fertilizer material. In the middle and late stages of pepper growth, there are many plants bearing fruit, and it requires a large amount of fertilizer. The base fertilizer was not applied with organic fertilizer, insufficient topdressing, and land with premature deterioration. After each harvest, water-soluble fertilizer (N:P:K=2:1:2) 10 kg or urea 10 kg plus sulfuric acid was used in combination with watering. Potassium 7.5 kg or diammonium phosphate 10 kg continuously applied 2-3 times.
2. Leaf spray fertilizer. Apply 0.3% KH2PO4 solution or 1% superphosphate leachate or 1%-2% KNO3 solution every time harvesting, spraying once every 7-10 days. 2-3 times; the results later, sprayed once every 5-7 days 0.3% potassium dihydrogen phosphate solution or 0.2% urea liquid can increase the weight of the fruit, make the fruit bright color, increase the level of pepper.
Second, moisture management
During fruit enlargement, there is a lot of water needed. If the water supply is insufficient, the fruit enlarges slowly, the skin of the fruit shrinks, the color is dull, and the deformed fruit is formed, which affects the yield and quality. However, if the water is too much, it can easily result in falling, fruit dropping, rotting, and death. seedling. If it is flooded for several hours, it will cause the death of chili peppers.
To harvest fresh pepper as the main pepper field, after each harvest, according to the water conditions appropriate watering, drought, generally every 7-10 days pouring a water; to harvest dry pepper-based plots in the late period of appropriate control Water, stop watering 15-20 days before harvest. Peppers are not tolerant to drought and are more afraid of earthworms. If there is less rain, watering should be done a few times. If there is accumulated water, it should be eliminated in time, otherwise it will cause the death of fallen leaves.
