Chili fertilization control
Pepper (including sweet pepper) is an important fruit and vegetable vegetable that is the key to high yield fertilization. After a long-term production practice, the pepper fertilization technology has summed up a good set of experience, namely, “light application of seedlings, stable application of flower buds, heavy application of flower and fruit fertilizer, early application of autumn fertilizerâ€.
I. Light application of Miaofei
It has a good effect on promoting the early development of pepper plants. Generally, after transplanting, combined with the appropriate amount of manure as a seedling fertilizer, it should not be applied to avoid excessive growth.
Second, stable application of flower bud fertilizer
From the time when the plant is budded to the first time, the plant is planted in large quantities and the fruit is still not much. In this period, it is necessary to apply appropriate amount of fertilizer to meet the flowering and fruiting needs of the pepper, and to prevent excessive planting and lead to plant growth. Falling flowers. Generally, 1000 kg of manure can be applied per 667 m2, and 5-8 kg of urea and 7-8 kg of phosphate fertilizer can be added.
Third, re-apply flower and fruit fertilizer
From the first harvest to the beginning of the autumn, this period is a period of fruitful results of the plant, and it is necessary to focus on fertilization. Generally, 1500-2000 kg of livestock manure is applied per 667 m2, 25-40 kg of phosphate fertilizer and 10 kg of urea. Because of the large amount of application, the fertilizer should be applied 6-10 cm away from the roots of the plants to avoid burning the roots. Usually topdressing every 15 days, a total of 4-5 times.
Fourth, early application of the autumn fertilizer
Turning the autumn fertilizer is very important for the mid-late ripe varieties, which can promote the later results and increase the yield of autumn pepper. Usually 20 kg of NPK compound fertilizer per 667 m2 of animal manure per 667 m2 is applied separately before and after Liqiu. Turning the autumn fertilizer can not be applied too late or it will be difficult to work due to the temperature drop.
In short, high-yield cultivation of pepper should not only apply the base fertilizer, but also scientifically replenish the topdressing according to the requirements of nutrients in different growth stages of pepper to ensure the early development, long-term, and no premature senescence of the pepper to achieve high quality and high yield.
