What kind of fertilizer does rose use to fertilize?

Rose fertilizer uses nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, calcium fertilizer, magnesium fertilizer, zinc fertilizer, boron fertilizer and other trace element fertilizer. Among them, the largest fertilizers are nitrogen, phosphorus and potassium, and fertilization is applied at 3:1:2 rate as far as possible in the early growth stage and 3:1:3 rate at flowering stage. Field management is mainly organic fertilizer and compound fertilizer, and about 3000-4000 kg of fully mature organic fertilizer is needed per mu.

How to fertilize roses?

The main results are as follows: 1. when planting, it is generally necessary to apply sufficient base fertilizer in the field combined with soil preparation, and the base fertilizer is mainly organic fertilizer and compound fertilizer, so as to improve the sustainable fertility for the growth of roses and meet the needs of plants for trace elements. Generally, 3000-4000 kg of fully mature organic fertilizer is applied per mu. With 30-40 kg of high concentration compound fertilizer, the application of base fertilizer is best after defoliation in autumn, and as soon as possible, it is generally ditched, so that the root system can sprout new roots. so that it can grow vigorously after the beginning of spring next year, and if the base fertilizer is applied too late, it will be disadvantageous to the normal growth of the plant.

2. In addition to applying sufficient basal fertilizer, roses have a great demand for fertility during some growth periods, so they need to apply available fertilizer in time to provide plant growth, usually 3-4 times a year.

The main results are as follows: (1) in the budding stage, when the temperature rises and the underground root system begins to grow and develop, it is necessary to topdressing compound fertilizer to promote the rapid growth of plant branches and leaves.

(2) the flower bud stage, which is the incubation period of the flower bud, sprouts and spreads leaves, and the root growth reaches the peak, which requires a great amount of fertilizer, so it is necessary to apply fertilizer in time.

(3) the full flowering stage, which is the key period of rose, is related to the height of yield and the quality of flowers, but the nutrients of the plant can not meet the needs of growth, so it is necessary to topdressing the available fertilizer in time.

(4) after flowering, the branches and leaves stop growing, the flowers have matured and harvested, the photosynthesis of the plant is still going on, and a large amount of nutrients accumulate in the root system. Whether to top fertilizer or not can be decided according to the plant condition.

The above is the introduction of what kind of fertilizer roses use to fertilize. I hope it will be helpful to you.
