Planting Technology of slightly Hot Pepper in greenhouse

? First, raising seedlings:

The flower buds of the middle and lower parts of pepper have been differentiated at the seedling stage, so the cultivation of sturdy seedlings is very important for the quality of flower bud differentiation and early flowering and fruiting. In the suitable temperature in the seedling stage, the seedling age is generally about 35 days, and it is planted when the bud is not in bloom. There are usually 9 to 13 true leaves. The seedling age is too short to blossom and set fruit.

? 2. Soil preparation, fertilization and planting:

1. Pepper likes potash fertilizer and phosphate fertilizer. Phosphate fertilizer should be fully applied in combination with organic fertilizer retting and ripening, and more potash fertilizer should be applied. Under normal circumstances, 50 kg of heavy superphosphate (46% phosphorus) is used per mu. The application of too much nitrogen fertilizer makes the leaves and branches tender and easy to grow, which is disadvantageous to flowering, fruit setting and later growth, the fruit becomes green and the fruit expands slowly.

2. The winter greenhouse should be planted around the end of September.

3. Before and after planting, the soil and planting holes should be disinfected to prevent root rot and stem rot in time (blight is rotten neck root).

? III. Management:

The main results are as follows: 1. Pepper is not resistant to drought or waterlogging. The variety has developed root system and vigorous growth. Before flowering and fruit setting, do not flood or water too frequently. Control the growth to prevent overgrowth and retting roots.

2. The suitable growth temperature of pepper is between 15.5 ℃ and 35 ℃. If the temperature is too high or too low, the normal flowering and fruiting will be affected. The suitable temperature in the shed should be controlled at 18 ℃-28 ℃.

3. Harvest door pepper and pair pepper in time to ensure normal flowering and fruit setting in the middle and upper parts.

4. The middle and upper part of the product has strong continuous fruit setting ability, large fruit and high yield. Fertilizer and water management should be strengthened after fruit setting. High nitrogen, high potassium, high calcium and fertilizers containing medium and trace elements were applied in time to ensure the yield and commercialization of fruits in the middle and later stage. (large amount of fruiting period, nitrogen: phosphorus: potassium = 18:5:22 and trace element fertilizers containing calcium, magnesium, zinc, iron and other trace elements, topdressing 30,50kg per mu (saleable area). Pepper harvest should not be empty, in case the upper part of the vigorous growth does not bear fruit.

6. Pepper should be sprayed with fungicide before and after harvest to prevent germs from invading from the wound and causing stem rot.

? 4. Relevant tips:

1. Root rot and stem rot (root rot) are important diseases of pepper. When planting hot pepper, special preparations should be applied at acupoints to control and prevent them as soon as possible.

2. If this variety is sprayed with chemical growth control agents such as B9, dwarf, zhuangsu, paclobutrazol, uniconazole and so on, it will make the fruit shorter, bend and darker, and affect the yield and quality, so it should be used with caution.
