For the farmers who grow pepper, more manure and phosphorus and potassium fertilizer can effectively promote the growth of pepper, improve the quality and yield of pepper, and have a very good help to improve the planting efficiency. So, what's the best fertilizer for chili? How do you put the top dressing on the pepper? This article will give you a detailed introduction, for your reference.
1 and first topdressing
After flowering and fruiting, the door pepper and pepper have been formed and timely fertilizer should be applied. The first topdressing should be done 3~4 weeks after planting (20~30 d after planting). This is the process of hot pepper after planting from green to yellow to green pepper, the door has small flowering and fruit, lower stem branch gradually, showed that the root has been more developed, each branch has 4 ~ 5 leaves, fruit growth will accelerate. Irrigation is needed at this time. Combined with irrigation, 5 kg of urea or diluted manure water is applied every 667 m2. The topdressing can promote the coordinated growth of roots, leaves, stems and fruits. After 1 weeks of dressing, pepper dark green leaf color, leaf increased gradually thickened, branch elongation thickening, small fruit dark green light bright, small will be closed. When asked to increase the amount of fertilizer in some trace elements required for the growth of pepper, need to foliar nutrient solution (as part of "liquid fertilizer and fruit spirit).
2 and second topdressing
Should be 5~6 weeks after planting (35~40 d after planting), that is, first times after the first half of topdressing. At this point, the root system of the plant is developed, the absorption capacity is strong, and the leaf photosynthetic rate is the most abundant, and the top dressing should be applied. Every 667m2 application of N, P, K 15% or 10 kg potassium dihydrogen phosphate compound fertilizer; meanwhile, foliar application of Ecuador, receiving composite fruit, such as melon, vegetables, increase the spirit of Wang Ling leaves the intermittent spraying effect is better, to meet the hot pepper stem and leaf growth and fruit rapid expanding needs. The fertilizer, pepper branches accelerate elongation and thickening of the main stem internode 5 ~ 9 cm in length, each section of uniform length, leaf amount, flat leaves, moderate size, green fruit, fruit surface smooth, soon to enter the harvest period.
3, applying CO2 fertilizer
After applying fertilizer second times, the greenhouse has been covered at this time, and the photosynthesis is a little worse, so the greenhouse CO2 fertilizer should be applied. Especially the old shed, shed more pepper to increase photosynthesis, promote the production of CO2, in order to facilitate the growth of fruit trees.
