What are the control methods for loquat trunk rot disease?
In recent years, loquat trunk rot disease has occurred especially severely in some places, posing a serious threat to loquat production. According to surveys, the varieties Luoyangqing and Dahongpao are the most susceptible to the disease. In the early stage of the disease, the base of the main trunk rots first, and then it gradually develops upward along the branches and trunk,

What are the key technical points for post-harvest pest and disease control in loquat?
Currently, most loquat fruit has been harvested. In addition to strengthening fertilizer and water management, pest and disease control is also an important prerequisite for ensuring whether the fruit trees can grow and develop normally and flower and bear fruit later. The main pests and diseases after loquat harvest include leaf spot disease, pear psylla, mites, aphids, etc.,

In loquat cultivation, autumn and winter management is key
Loquat is a fruit that comes to market in spring in our province, with a high market price and good returns. Loquat generally blooms in autumn and winter, with a flowering period of about 90 days. Because flowering and fruiting consume a large amount of nutrients, and because it is prone to freezing damage in winter, strengthening autumn and winter management of loquat is the guarantee of obtaining high quality and high yield

How should loquat be fertilized when grown? A detailed explanation of scientific fertilization methods for loquat
Loquat is an evergreen fruit tree that grows and bears fruit year-round without dormancy, so it requires more fertilizer than deciduous fruit trees. Fruiting trees in particular require more potassium. The types, amounts and timing of loquat fertilization should be combined with soil fertility, tree age, plant vigor, and the different growth stages of shoots and roots

Detailed Guide to the Key Cultivation and Management Points for Mature Loquat Trees
I. Rational Fertilization 1. Flower-promoting fertilizer. Apply in September before flower buds appear, to promote good flowering. Mainly use slow-release organic fertilizer: oil cake + human manure and urine + compound fertilizer. 2. Young fruit fertilizer. Apply in February to March after fruit thinning, to plump up the spring shoots and grow the young fruits. Apply quick-acting nitrogen, phosphorus, and potassium compound fertilizer + human manure

Detailed Explanation of Key Techniques for Spring Planting of Loquat
(1) Land preparation: When building a loquat orchard on flat land, planting trenches should be dug, generally 0.80--1.0 m wide and about 0.80 m deep. The distance between planting trenches is generally about 3 m, and the length of the planting trenches depends on the size of the orchard site or the length of the slope. When digging the trenches, keep the topsoil and subsoil separate, placing the topsoil on the upper side. When backfilling, first backfill the topsoil, and use 3--4 layers to bury and press in straw, rice straw, farmyard manure, phosphate fertilizer, etc. Generally, base fertilizer is applied 1--2 months before planting.</p><p>Loquat has wide adaptability to soil. Generally, sandy or gravelly loam can be used for cultivation, but soil with deep soil layers, loose texture, high humus content, strong water and fertilizer retention, and which is not prone to waterlogging is best. If the soil is too clayey, some sandy soil can be mixed in. If the soil is relatively acidic, lime should be appropriately increased in combination with fertilization to improve the soil. Sloping land must be terraced into contour bench terraces. Mountain soil is relatively barren, so large holes and heavy fertilizer must be used for cultivation. Each planting hole should be 1 m long and 1 m wide, and 0.8--1.0 m deep. At the same time, each hole should be backfilled in 3--4 layers with more than 50 kg of barnyard manure, green manure, etc., 0.8--1 kg of phosphate fertilizer, and 1 kg of quicklime. The fertilizer must be fully mixed with the soil. Farmyard manure should be placed in the bottom layer to facilitate root absorption. Phosphate fertilizer and lime should be placed in separate layers and must not be mixed. Wait until the fertilizer has decomposed and the soil has settled after loosening before planting. (2) Select excellent strong seedlings: Variety selection should follow the principle of "matching species to site", and at the same time require grafted varieties with relatively large fruit, generally around 50 g, thick flesh, sweet taste, high yield, and strong disease resistance. (3) Planting time: Plant before the spring shoots sprout in spring, generally around March in spring. If too late, it affects the emergence of spring shoots. When the soil is too wet or the wind speed is too high, it is not suitable for planting. (4) Planting density: Close planting is generally determined according to the cultivated variety, soil fertility, terrain, etc. Usually, barren sloping land is planted more densely than fertile, deep flat land, and weak trees are planted more densely than vigorous trees. The plant-row spacing is generally 2 x 3 m, with 111 plants per 667 sq m. It can also be 2 x 3.5 m or 2.5 x 3.5 m. (5) Rational arrangement of pollinizer trees and appropriate variety combination: Loquat is mostly self-pollinated, but some varieties show self-incompatibility. Therefore, in the same orchard, 2--3 varieties should be cultivated, but the varieties are required to have similar full-bloom periods to facilitate pollination. Generally, for every 2 rows of the main cultivated variety, plant 1 row of pollinizer variety, with a ratio of 2:1. Bee release during the flowering period can also be combined to increase the pollination rate. Loquat orchards should combine early-, mid-, and late-maturing varieties, so that different maturity periods can meet market supply and demand. Generally, early-, mid-, and late-maturing varieties are combined at 1--3:5--6:2--4. (6) Rational planting: Transplanting seedlings with soil generally gives a high survival rate. If transplanted without soil, the roots should be dipped in mud slurry. When planting, place the seedling at the center of the planting point and distribute the root system evenly in the hole, then fill in soil layer by layer so that the root system fully contacts the soil. While filling, firm the soil, water with root-setting water, cover with soil again to near the graft union, water again with root-setting water so that the soil and loquat root system fully contact, then fill with soil again. Generally, the backfilled soil is about 10--20 cm higher than the ground surface. Around each loquat seedling, make an earth ring about 5 cm high to facilitate watering, fertilizing, or intercepting precipitation. (7) Trunk determination: The trunk height is determined at 30--40 cm above the graft union. The branches above it should retain a length of about 20 cm. Select and retain 3 plump buds above the trunk height and train them as main branches, with each main branch facing 120 degrees apart. </p>
