loquat
The fruit is spherical or oblong, 2-5 cm in diameter, yellow or orange, with rusty fur outside, which falls off quickly; Seed 1-5, spherical or oblate, diameter 1- 1.5 cm, brown, shiny, and the seed coat is papery. Flowering 10- 12, fruiting in May-June. [ 1-2]?
Mature loquat fruits are also hung on the tree in bundles, each fruit is 3-5 cm long and is round, oval or long "pipa-shaped". The surface of loquat is covered with fluff. When immature, it is turquoise, hard and fragrant. After maturity, the skin is generally light yellow, and some are dark and close to orange-red. The pulp is soft and juicy, mainly divided into white and orange; It is called "white sand" (white loquat) and "red sand". Among them, white sand tastes sweet and the fruit shape is small; Red sand is relatively acidic or quite acidic and relatively large. Each loquat fruit has five ovaries, one to five of which develop into brown seeds, while the artificially cultivated seedless varieties have no seeds.

Soil requirements
1, loquat planting should choose high-yield dry land cultivated over the years with flat, deep, loose, fertile soil layer and rich organic matter, with soil pH of pH6.0 as the most suitable, and water source must be considered in land selection, so as to ensure that the orchard can be irrigated from June1/kloc-0 to May of the following year, with convenient transportation. It is not advisable to choose low-lying land that is easy to accumulate water. Before planting, plough deeply for more than 30cm.
2, irrigation conditions should be planted in February ~ March; No irrigation conditions should be planted in mid-June (early rainy season).
3. The climate is warm, and loquat trees grow fast. The planting density is 960.5 plants /h and the plant spacing is 3m×3.5m It can be put into production after three years of planting. Thinning after a certain number of years is beneficial to management and early high yield.
4. In September ~ 65438+1October of the year before planting, while the soil is wet, dig a planting pit with a depth of 60cm, a mouth width of 80cm and a bottom width of 70cm, and pile the topsoil and subsoil separately. 30kg farmyard manure or sugar mud and 0.8kg calcium magnesium phosphate fertilizer are applied to each planting pit as base fertilizer, which is mixed with topsoil and applied to the planting hole, and then the original subsoil is completely backfilled. Backfilling work must be completed two months before planting loquat seedlings, so that the base fertilizer can be fully decomposed and filled.
Transplanted seedlings should be free of pests and diseases, with dark green leaves and developed roots. The joint thickness should be above lcm, and the joint should heal well, 45 ~ 50 cm above the joint (preferably with branches). When planting, the root neck of seedlings should be flush with the ground, not too deep, and some leaves and branches should be cut off to reduce evaporation.
When planting, let the fine soil fully contact with the root system and compact the soil around the root system. Each plant must be watered with about 20L fixed root water, and then covered with a layer of fine soil after the water seeps down. Dry at 45 ~ 50 cm above the ground.
