Loquat trees had better not be potted. If the trees are malnourished and lack auxin and micronutrients, the quality of loquat flowers will be poor and the flowers will not bear fruit. Loquat is a subtropical tree, which requires high temperature. Only when the annual average temperature is above 12℃ can it grow normally. In most northern areas such as Shandong, Beijing, Tianjin and Hebei, there will be severe cold weather in winter, which is not suitable for planting loquat trees.
Extended data:
Loquat trees need fertilization three times a year. Generally, farm manure is the main base fertilizer before loquat flowering, and the fertilization amount accounts for 70% of the total fertilization amount in the whole year; The spring fertilizer before the spring shoots of loquat trees begin to grow is mainly nitrogen, phosphorus and potassium compound fertilizer, accounting for 20-30% of the annual fertilization; The summer fertilizer before or after loquat harvest is mainly decomposed organic fertilizer, accounting for 10% of the annual fertilization.
In the first two years of young loquat tree planting, the whole flower spike of loquat tree can be thinned, so that the loquat tree can form the skeleton of crown as soon as possible. If there are too many spikes in loquat trees, the spikes on the long branches and weak branches in the upper trunk of the crown can be thinned out, and the ratio of new shoots to spikes should be kept at 2: 1.
The spikes formed by the top branches of loquat trees are large and numerous, which can remove excessive supporting shaft and buds on the spikes. Spikelet-type varieties generally leave 2-3 supporting shafts in the middle except the base supporting shaft and the top shaft. 2-3 supporting shafts can be left in the big-spike loquat tree, and all the upper supporting shafts are removed.
