A brief discussion on the maintenance and Management of several kinds of Flower Bud differentiation

As we all know, flower bud differentiation usually goes through two stages: physiological differentiation stage and morphological differentiation stage. In the process of flower bud differentiation, light, humidity, water and fertilizer play a very important role in flower bud differentiation, so how to manage it? Let's briefly talk about the main points of the management of the following kinds of flowers in this period.

Chimonanthus mume

The main results are as follows: (1) after flowering in April, sufficient base fertilizer should be applied, preferably mixed organic fertilizer of fermented rotten chicken manure and calcium superphosphate.

(2) June to August is the flower bud differentiation and budding stage of Chimonanthus mume, which is an important period of conservation. Nitrogen, phosphorus and potassium compound fertilizers dominated by phosphorus should be applied once or twice, and attention should be paid to loosening the soil, weeding and preventing the soil from being too wet.

(3) after defoliation in autumn, topdressing should be applied once or twice to make the buds full and the flowers fragrant.

Chrysanthemum

The main results are as follows: (1) the vegetative growth stage of chrysanthemum is spring and summer. At this time, adequate light and the supply of nitrogen and potassium-rich fertilizers should be guaranteed to make the branches and leaves luxuriant and the root system developed.

(2) in the reproductive growth stage, flower bud differentiation begins in mid-late August. During the growth of flower buds, the hours of light should be limited and more phosphorus-containing fertilizers should be applied.

(3) after the Beginning of Autumn, chrysanthemum should gradually increase the amount and times of fertilizer application so as to dwarf its plants and improve disease resistance.

Camellia

The main results are as follows: (1) from March to April, most camellias bloom and a large amount of nutrients are consumed. At this time, nitrogen fertilizer should be applied mainly to restore tree potential, promote new roots and grow new buds.

(2) the new branches matured from May to June and began to enter the stage of flower bud differentiation, and phosphate fertilizer was the main topdressing from April to June to meet the needs of plant seedling pregnancy.

(3) Bud appearance does not mean that all flowers bloom. Buds grow on the plant for seven to eight months before they blossom. Dead buds and buds often appear. From July to August, the concentration of phosphorus-based bud protection fertilizer should be light.

(4) the camellia entered the second growth peak from October to November, the bud expanded rapidly and began to blossom, and the topdressing was mainly phosphorus and potassium fertilizer.

Osmanthus fragrans

The main results are as follows: (1) New shoots sprout and grow from February to March in early spring, semi-Lignification in June, and flower bud differentiation in August, thin fertilizer mainly composed of phosphorus and potassium should be applied once or twice to promote flower bud differentiation and bud pregnancy. The organic fertilizer should be fermented and ripened, and the concentration of chemical fertilizer should not be too high. Urea is 0.5%, calcium superphosphate is 2%, and should be poured evenly into the soil.

(2) after the flower fades, it is necessary to apply rotten organic fertilizer.

(3) the mixed fertilizer of soybean cake and superphosphate should be applied in winter to ensure the growth of new shoots and the nutrition of flower bud differentiation in the coming year, which is the key to the number of sweet-scented osmanthus flowers.

In different growth and development stages of flowers and plants, it is best to carry out balanced fertilization and special fertilizer to meet the nutritional needs of flowers and promote them to produce ideal flowers.
