Introduction of management techniques of loquat in spring
(1) soil preparation: planting ditches should be dug for loquat orchards in flat land. Generally, the ditches are 0.80m in width and 0.80m in depth. The distance between planting ditches is generally about 3m. The length of planting ditches depends on the size of the garden or the length of the slope. When digging ditches, open the topsoil and core soil, put the topsoil on the upper edge, backfill the topsoil first, and divide it into 3 Mel.

Spring shoot fertilizer should be applied to adult loquat trees in time.
Loquat likes warm and humid climate, blossoms in autumn and winter, and fruit ripens in late spring and early summer. Since last autumn, there has been drought and little rain in Guangdong, so fruit growers should actively water and fertilize loquat, especially adult trees should apply spring shoot fertilizer in time to strive for a bumper harvest this year. First, young tree fertilization (1-3 years) loquat young tree.

How to manage the postharvest loquat
In order to overcome the phenomenon of big and small years caused by poor management of loquat, postharvest management must be strengthened to prepare for a good harvest next year. 1. Strengthen the management of fertilizer and water. (1) from April to May after fruit harvest, the annular ditch under the canopy was applied, and each plant was fertilized with 100 kg of rotten human feces or cattle and pig manure.

Scientific Management of Postharvest Loquat
At present, the basic harvest of loquat is over, and the postharvest production management is directly related to the tree potential growth and next year's fruit. The postharvest production management of loquat should be carried out mainly from three aspects: fertilization, pruning and pest control. Full postharvest fertilizer loquat should be fertilized in time to promote the development of summer shoots, mainly nitrogen fertilizer.

Key points of loquat cultivation techniques in spring and summer in South China
The cultivation and management of loquat in spring and summer in southern China is very important, which has a great influence on the yield and quality of loquat. Only by conscientiously doing a good job in loquat cultivation and management, fertilizing, pest control, flower and fruit thinning and fruit bagging, loquat not only has high yield, good quality, low pesticide residue and low pesticide residue.

Do a good job in postharvest management of loquat to ensure a good harvest in the coming year
Loquat is basically picked in May, and postharvest production management is directly related to tree potential growth and next year's fruit. The postharvest production management of loquat should be carried out mainly from three aspects: fertilization, pruning and pest control. Full postharvest fertilizer loquat should be fertilized in time to promote the development of summer shoots, mainly nitrogen fertilizer.

High yield and good pre-flowering Fertilizer for Loquat
The flowering period of loquat tree is as long as 3 months and blossoms from October to February next year. Generally speaking, the flowering stage of loquat tree is divided into three stages: the first flower blooms from October to November, the fruit is larger, the quality is good, but it is susceptible to cold; the second flower blooms from November to January of the following year, and the fruit quality is inferior to that of the head flower, but it has strong cold resistance and fruit setting rate.

Loquat smart fertilization helps crack prevention and sweetening
Loquat fruit cracking is easy to occur in rainy spring, and reduce sugar accumulation, reduce fruit sugar content, so that fruit taste becomes light and quality is poor. If organic fertilizer, phosphorus potassium fertilizer and calcium fertilizer are applied during this period, it can effectively prevent fruit cracking, promote sugar synthesis and accumulation, and improve the sugar content of fruits.

Orchard disease of mango: bituminous coal disease
Mango flat-beaked leafhopper is also called leaf hopper to damage flower ear and young fruit, resulting in falling flowers and fruit, poor harvest or even loss of harvest, and serious soot disease, but also damage young buds, tender shoots and leaves, causing buds and leaf deformities. It usually occurs more often in the flowering stage, the humidity is high, and the closure of the crown is more likely to cause the worm. Often in Hainan.

Treatment of "empty bosom" of mango
Longicorn beetles belong to Coleoptera and Cerambycidae, which occur in mango producing areas of southern China. By feeding on the branches with larvae, the growth of the damaged plants is weakened, and in serious cases, the damaged branches are easy to be broken by the wind. The insect produces one generation a year, and it overwinters mainly as larvae, and a few pupae or adults can also overwinter in the pores. The following year.

Timely control of loquat yellow caterpillar
Loquat yellow caterpillar adults are commonly known as "inverted butterflies". The larvae eat buds and tender leaves, and when rampant, they also endanger old leaves, tender stem barks, flowers and fruits, and only upper epidermis and veins remain in the injured leaves. The first instar larvae of the insect are clustered. The second year old began to disperse the harm, and the food intake increased greatly after the third year old. This insect is the most common and serious kind of loquat.

Promote the coloring of cherries in the greenhouse
Spraying non-mulching bag and spraying fruit surface can play the role of bagging, will not affect fruit respiration, can also prevent fruit rust and cracking, improve fruit surface coloring and brightness, reduce residual poison and improve quality. Spraying new high-fat membrane on leaves can prevent leaves from being infected with virus, make branches and leaves green and luxuriant, accumulate photosynthetic products and

Planting period and method of Cherry in Spring
At present, the main tree shapes in cherry protected area production are natural happy shape, improved trunk shape, trunk sparse layer shape and slender spindle shape. The natural happy trunk is 30-40 cm high, with 3-5 main branches, 6-7 lateral branches on each main branch, and the angle between the main branch and the trunk is 30-45 degrees. The height of the tree is controlled at 1.5 to 1.8 meters.

Cultivation methods of dwarfing cherry seedlings
The cherry trees are too tall to grow in the greenhouse; it takes 5 to 6 years for natural production to bear fruit and 10 years later to enter the high yield period. The investment return period is long and the management cost is high. After years of exploration, fruit tree experts in China have studied the grafting of big cherry varieties with hairy cherry as rootstock and FL-80 plum as interstock.

Control methods of mango weevil
1. Mango leaf-cut weevil is widely distributed, adults feed on mango tender leaves, causing the leaves to dry up, or females lay eggs on the tender leaves and bite off the tender leaves from the base, affecting plant growth. Control method: during the tender shoot growth period, ① picked up the fallen leaves of the injured plants every 3 days, dried them in the sun and burned them, killing young plants.

Occurrence and control of mango anthracnose
The main results are as follows: 1. the main damage symptoms are mango flowers, fruits and tender shoots. After the young leaves were infected, there were many round brown spots with yellow halo around them, and gradually expanded into round, polygonal or irregular brown spots, and then ruptured and perforated.

Comprehensive control technology of mango soot disease
The main results are as follows: (1) the reason of mango flower and fruit drop is 1. When mango meets low temperature, overcast and rainy weather during flowering and young fruit stage (the temperature is lower than 11.5 ℃) and lasts for a long time, the flower and fruit drop is serious. The flower ear suffers the death, appears a large number of abnormal fruit, aborts the fruit, easy to cause the natural shedding. 2. Diseases and pests harm the pests of mango.
