The nutritional characteristics of pepper growth.
The pepper continuously absorbs nitrogen fertilizer from the early stage of growth to the harvesting stage, and there is a direct relationship between the yield and the amount of nitrogen absorbed. The spicy taste of pepper is related to the amount of nitrogen fertilizer, and the application amount will reduce the spicy taste. For dried chili, the nitrogen fertilizer should be properly controlled to increase the proportion of phosphorus and potassium fertilizer. If the amount of nitrogen fertilizer is too much, the vegetative growth is too strong, and the fruit will produce umbilical rot due to the inability to obtain calcium supply in time. In the early flowering period, it is necessary to control the nitrogen fertilizer. Otherwise, the plants are long and the reproductive growth is delayed.
As the plants continue to grow, the amount of phosphorus absorbed increases. However, the amount of change in absorption is very narrow, and the total absorption is about 1/5 of that of nitrogen. Insufficient phosphorus can cause falling buds and falling flowers. Phosphorus is an important factor in the development of flower buds.
Potassium is less absorbed in the early growth stage of pepper, and it increases after picking fruit. In the result period, if the soil potassium is insufficient, the leaves will show potassium deficiency, defoliation occurs, the fruit setting rate is low, and the yield is not high.
The amount of calcium absorbed is lower than that of tomato, and if it is insufficient, the umbilical rot of the fruit has been induced. Calcium is indispensable throughout the growth period.
At the initial stage of planting, the absorption of magnesium is less, and the absorption amount increases during the harvesting period. At this time, if magnesium is insufficient, the veins become yellow and become magnesium deficiency, which affects plant growth and fruiting.
When the pepper is deficient in boron, the color of the leaves is yellow, the growth of the heart leaves is slow, the xylem of the roots becomes black and rot, the growth of the roots is poor, the flowering period is delayed, and the flowers are unrealistic, which affects the yield.
Regardless of the time of the pepper, proper use of fertilizer is important. It is necessary to apply scientific fertilization. It is important to fertilize at what time and what kind of fertilizer you like. Especially during the period of reproductive growth and vegetative growth, you should not use it to avoid unnecessary trouble.
Fertilization technology.
1. Base fertilizer: 5000 kg per mu, 5000-8000 kg of organic fertilizer (pig manure, human excrement, soil fertilizer, etc.), 25 to 50 kg of superphosphate and organic fertilizer, mixed with potassium sulfate 25~ 30 kg. Apply 60% base fertilizer before the preparation of the ground, and apply 40% of the ditch when planting.
2, seedling: In the 11.3 square meter seedbed, apply 150 ~ 200 kg of organic fertilizer, apply 1 to 2 kg of superphosphate, and plow 3 to 4 times.
3, the stable cultivation of manure water: the stems and leaves above the door fruit grow 3 to 4 knots, combined with watering to chase the manure urine 2000 kg per mu. After half a month, the second amount is applied as before. Apply 1500-2000 kg of organic fertilizer or 40 kg of ammonium sulfate per mu.
4, foliar topdressing: flowering results, can also spray 0.5% urea plus 0.3% potassium dihydrogen phosphate.
