Fertilizer and water management of bonsai plum seedlings
Plum seedlings Organic fertilizer in bonsai soil is far from meeting its growth and development needs, so fertilizer and water management must be strengthened during the growth period. Fertilization should be mainly organic fertilizer and chemical fertilizers should be applied reasonably. Mix the rotten organic fertilizer into the pot; apply quick-acting nitrogen fertilizer once before germination or flowering, and water each plant about 1 kilogram to promote neat and flowering. At the end of the peak period, spray 0.3% urea or 0.2% potassium dihydrogen phosphate once every 10-15 days, spray 2-3 times continuously to promote the expansion of young fruits and accelerate the growth of new shoots.
0 From late June to early July is the flower bud differentiation period. Dilute fertilizer and water can be applied, once every 10 days, 2 to 3 times in a row, to promote flower bud differentiation and improve fruit setting rate. When the growth is vigorous from August to September, in order to control the growth of new shoots, the use of nitrogen fertilizer should be stopped, mainly phosphorus and potassium fertilizer , and thin fertilizer should be applied frequently. The moisture of the plum seedling bonsai should be properly controlled and watered once a day. The watering time should be carried out in the morning and evening to avoid high temperatures at noon. Master the principle of "no watering without drying, watering thoroughly". Leaf spray can be performed in high temperature seasons to increase air humidity and reduce blade temperature. Apply decomposed organic fertilizer after the leaves fall. Watering should be strictly controlled during the dormant period, and the soil in the pot should not be too dry.
