After planting, it is necessary to grab a sunny day and topdressing seedling fertilizer, and the dosage should not be too much and too thick each time, otherwise it will easily lead to excessive growth and delay flowering and fruiting. When the first and second layers bear fruit, more fertilizer should be applied to promote fruit growth. After fruit picking, it is more necessary for the soil to have enough fertilizer and water for plants to grow and bear fruit normally.

If it rains heavily before the soil is dry after watering, the phenomenon of falling leaves and dying will be quite common, especially during the period from ups and downs to beginning of autumn. Therefore, when irrigating, we must decide the irrigation time according to the weather forecast. The depth of irrigation shall not exceed three-quarters of the side ditch, and it shall be carried out at night or in the early morning, and emergency irrigation and drainage shall be carried out.

2, intertillage weeding, increase the application of plant ash, reduce humidity and ventilation.

Through intertillage, soil hardening can be broken, soil ventilation can be improved, the development of pepper root system can be promoted, and a good soil environment can be created for pepper growth. The intertillage time should be chosen in sunny and high temperature period or before high temperature, shallow near the roots and deep between rows to avoid root injury. After intertillage, a large number of weeds died of water loss, and at the same time, they had the function of soil disinfection and sterilization. Combining intertillage to increase the application of plant ash, one is to reduce soil moisture; The second is to increase soil nutrients.

3, pruning, to prevent falling flowers and fruits.

When pruning pepper, keep the trunk and 2-3 lateral branches, wipe off all the lower axillary buds, and cut off the inner branches and old diseased branches to make the cavity ventilated and light-permeable. Leave 2 leaves for branches above grade 3, 1 fruit, and 2 leaves for newly grown branches, and remove the old diseased leaves at the lower part to promote the growth of upper branches and leaves and the elongation and expansion of fruits. At the same time, cultivate the soil again to promote new roots, and spray 2‰ urea, potassium dihydrogen phosphate and other fertilizers.

Extended data

Growing environment of pepper

1. Temperature requirements: adaptive temperature range 15 ~ 35℃, suitable temperature range 25 ~ 28℃, germination temperature 28 ~ 30℃.

2, moisture conditions: like to be wet, afraid of drought and flood, and require the soil to be wet without water.

3. Lighting conditions: the lighting requirements are not strict, and the light intensity is moderate. Sunlight 10 ~ 12 hours is beneficial to flowering and fruiting. The growth and development of green peppers need adequate nutritional conditions. Every 1 0,000 kg of green pepper requires 2 kg of nitrogen, 0 kg of phosphorus, 0 kg of potassium and 0.45 kg of calcium fertilizer. The requirement for soil is moist sandy loam, and the pH value of soil is neutral or slightly acidic.
