How many times a year does loquat blossom? How many times do you bear fruit? How can it blossom and bear fruit?

Loquat, also known as Jinwan, is a common cash crop in China. It has the laudatory name of "emperor of fruit". It is very popular because of its beauty, moistening lung and relieving cough. How many times a year does loquat blossom? How many times do you bear fruit? How can it blossom and bear fruit?

Loquat trees generally blossom in the same year and bear fruit in the following year, in which they bloom once a year, usually from October to December, and bear fruit once a year, from May to June of the following year. However, it takes three years for self-sowing, transplanting, grafting and planting of a loquat tree, and after four years of fruiting, 10-40 years is the peak fruit stage, and grafted seedlings are easier to blossom and bear fruit than real seedlings. If the seeds are planted, it will take a long time, at least more than 5 years, and grafted seedlings generally take more than 3 years to blossom and bear fruit.

Planting method:

1. Temperature

Loquat originates from subtropics and requires higher temperature. The annual average temperature of loquat can grow normally when the annual average temperature is more than 12 ℃, but the annual average temperature for economic cultivation should be 15-17 ℃, and there is no cold weather. Loquat flowering in late winter and early spring, low temperature in winter and spring will affect its flowering and fruiting. The temperature of-6 ℃ caused freezing damage to flowering and-3 ℃ to young fruits, and pollen germination above 10 ℃ was the most suitable for pollen germination at about 20 ℃. However, when the air temperature or ground temperature is more than 30 ℃, the growth of branches, leaves and roots is slow and poor, and the fruit is exposed to a high temperature of 35 ℃ 7-15 days before picking, which is easy to cause sunburn injury and even lose edible value.

2. Soil

Loquat has loose requirements on soil and wide adaptability. General soil can grow and bear fruit, but loose soil with more sand or gravel grows better. Loquat planting should choose flat, deep, loose, fertile and high-yield dry land rich in organic matter over the years, and soil pH6.0 is the most suitable. Water must be considered to ensure that the orchard can be irrigated from November of each year to May of the following year, and the transportation and transportation are convenient. It is not suitable to choose land which is low and flat and prone to stagnant water. Ploughing more than 30cm should be done before planting.

3. Planting time

Those with irrigation conditions should be planted from February to March, and those without irrigation conditions should be planted in mid-June (early rainy season). The climate is warm, loquat trees grow fast, the planting density should be 60-70 plants / mu, the plant-row spacing density is 3m × 4m or 3m × 3.5m, melon and fruit can be planted for 3 years, and thinning is carried out after a certain number of years, which is beneficial to management and early high yield.

4. Planting method

From September to October of the year before planting, the planting pits of deep 60cm, mouth width 80cm and bottom width 70cm were excavated while the soil was wet, and the topsoil and subsoil were stacked separately at the same time. In each planting pit, 30kg farm manure or sugar paste, 0.8kg calcium magnesium phosphate fertilizer were applied as base fertilizer, mixed with topsoil, and then all the original subsoil was backfilled. The backfilling work must be completed 2 months before the planting of loquat seedlings, so that the base fertilizer is fully mature and the filling soil is solid. Transplanting seedlings should be disease-free, thick green leaves, well-developed roots, graft interface thickness above lcm, interface healing well, 45~50cm above interface (preferably branched). When planting, the root neck of the seedling should be flat on the ground, not too deep, and part of the leaves and twigs should be cut off to reduce evaporation. When planting, let the fine soil fully contact with the root system, compacting the soil around the root, each plant must be irrigated with about 20L fixed root water, and then cover a layer of fine soil after the water seeps down. Dry at 45-50cm off the ground.
