Before planting, it is required to dig a 1-meter-deep and 1-meter-wide planting ditch(seed starter trays). The average application amount of high-quality basal fertilizer per mu is more than 6000 Jin. After covering the soil, golden pear is planted. It is necessary to select strong seedlings with complete root system, no diseases and insect pests(200 cell seed trays wholesale), no mechanical damage, and to irrigate them after planting, and to apply base fertilizer to deeply transform the soil every year.(cheap plastic 2x4 grow tray wholesale suppliers)
After falling leaves in autumn every year(square nursery pots), 4000 Jin of high-quality basal fertilizer is applied to each mu by deep ploughing, and the first time before germination, nitrogen fertilizer is mainly applied. For the second time, from the post anthesis to the flower bud differentiation, the multi-element compound fertilizer was mainly used, and for the third time(200 cell seedling trays wholesale), the potassium fertilizer was mainly used in the fruit expansion period, with appropriate P fertilizer.
In May of each year(plastic nursery pots manufacturers), 0.3% urea solution was used as the main fertilizer in the early stage, 0.2% ~ 0.3% potassium dihydrogen phosphate was used as the main fertilizer in the later stage, and less or no basic fertilizer was applied in autumn. Three to four times of combined fertilization and watering were before germination and flowering, long-term shoot growth, after fruit harvest and before soil freezing(32 cell seedling trays wholesale).

(cheap plastic 2x4 grow tray wholesale suppliers)In the year of watering, 70-80 cm should be reserved for fixed stem(seedling trays wholesale), 3-4 suitable buds with an interval of about 10 cm should be selected under the cutting mouth to stop eye injury, and the sprouted branches on the main branch should be stopped slowly(1 gallon nursery pots wholesale).
