This pear grows rapidly and yields high yields. It is planted the first year and bears fruit the following year, breaking the tradition of "three peaches, three apricots, four pears, and five years". Generally, a single fruit weighs around 150 grams, with the largest weighing over 350 grams. During the peak fruiting period, the yield per mu is 4000-5000 kilograms, and it can bear fruit continuously for more than 50 years

1. Strange fruit shape: Its fruit is shaped like a mango, kiwi, waist drum, or goose egg, with a ratio of vertical to horizontal diameters of up to 1.5, and a bright orange red color, which is unique both domestically and internationally.

2. Extremely nutritious: Its fruit has a soluble nutrient content of up to 17.6%, which is 3-6% higher than the world-renowned Chinese crispy pear, fragrant pear, and Japan's "Sanshui pear" and "Crystal pear", ranking first among all pears at home and abroad

3. Significant therapeutic effect: After repeated verification by tens of thousands of consumers over the past six years, regular consumption indeed has significant health benefits such as "resolving phlegm and cough, moistening the lungs and cooling the heart, clearing heat and detoxifying, and opening the chest to regulate qi"

6. Early fruiting and high yield: This variety has strong stress resistance, wide adaptability, easy flowering, easy cultivation and good management. It bears fruit in two years and yields in three years. During the peak fruiting period, the yield per mu is 4000-5000 kilograms, and the yield per mu is over 100000 yuan. Except for high-altitude and subtropical climate areas, it can be promoted and planted in most parts of the country

* There are also various ways to consume golden pearl fruit. In addition to fresh and cooked food, juicing and boiling soup are also good ways to consume it. In addition, it can also be made into fruit tea. The method is to take 300 grams of golden pearl fruit, 1000 grams of water, add an appropriate amount of rock sugar, boil for 30 minutes, eat the fruit and drink tea

Production method of Luoning golden pearl fruit

Early fruiting, high yield, and stable production. Plant 110-180 plants per mu, with results in the second year of cultivation and 10-15 kilograms per plant in the third year. During the peak fruiting period, the yield per mu is about 4500 kilograms, and there is no phenomenon of fruit bearing in different years. Mature late and resistant to storage. The fruit matures from late October to early November, and can be stored naturally in indoor boxes until April or May of the following year, which is beneficial for steady market release. Due to the late maturity period and gradually cooler weather, pests and diseases are difficult to erode, and there are almost no diseases such as black stars and stem rot. At the same time, it is not easy to be injured

Except for high cold and subtropical regions, planting is allowed in all other areas of China

Cultivation techniques

(1) Nursery cultivation: Jinzhuguo pear needs to be grafted for seedling cultivation, with Tang pear as the rootstock and layered seeds. The layering time is about 2-3 months, and the seeds should be sown in the first half of March of the following year using about 5 times the amount of wet sand stored at low temperature. Generally, strip sowing is used, with a row spacing of 40-50 centimeters, a planting amount of 1-2 kilograms per mu, and a planting distance of 10-15 centimeters. Starting from June, grafting should be done using the "T-shaped" bud grafting method, and the binding should be untied promptly after grafting. Pay attention to strengthening fertilizer and water management, disease and pest control, and cultivating high-quality seedlings

(II) Planting and Garden Construction: Choose a place with deep soil layers, fertile soil, good texture, sufficient sunlight, drainage conditions, and no environmental pollution to build the garden. Hillside land should be leveled and soil improved. When planting, large holes should be dug, sufficient fertilizer should be applied, water should be permeable, soil should be compacted, and a film should be covered. The planting density is 4 X 5 meters for water and fertilizer fields, and 3 X 4 meters for dry slopes. This variety has strong ability to bear white flowers, but pollination trees should also be arranged during planting

Management Techniques

(1) Trimming and shaping: When planting closely, natural spindle shapes can be used, with a stem height of 50-60 centimeters, a tree height of 3.5 meters, a crown width of 2.5-3 meters, and 12-15 main branches cut and left, with a configuration angle of 70-80 °. When planting sparsely, a small crown sparse layer shape can be used, with a stem height of 50 centimeters, 5-7 main branches, a tree height of 4-4.5 meters, and a crown width of 3.5-4 meters

(II) Soil, fertilizer and water management: The main approach is to increase the application of organic fertilizers, phosphorus and potassium fertilizers, and trace elements. Young trees should appropriately control the supply of nitrogen fertilizers and water to facilitate growth control and promote flower bud formation. Organic fertilizer can be applied in autumn, while topdressing can be applied during the germination and flower bud differentiation stages (at the end of May). Apply 3000-5000 kilograms of organic fertilizer, 10-20 kilograms of urea, 50-100 kilograms of phosphorus fertilizer, and 5-10 kilograms of potassium fertilizer per acre

(II) Disease and pest control: There are mainly branch and leaf pests such as longhorn beetles, aphids, and pear psyllids, as well as fruit pests such as pear weevils, pear bugs, and pear fruit eating insects. Effective prevention and control can be carried out using pesticides such as Miesu Li, Avicen Qing, and Da Gongchen
