of course can

The climate in the suitable planting area should not be lower than minus 1 degree, and it is suitable in the south of the Yangtze River.

Honey pomelo, a crop of Rutaceae and Citrus, is an excellent variety of pomelo, which has the advantages of early fruiting, high and stable yield, large fruit, beautiful appearance, tender and crisp meat, rich juice, moderate sweetness and honey fragrance. The purpose of cultivation and management of young honey pomelo trees is to promote the growth of roots and branches, and cultivate well-developed, early-bearing, high-yield and stable root groups and crowns. To this end, we should do the following work:

1. Reasonable interplanting of Guanxi honey pomelo has a large plant spacing, and the crown is still small within 1 ~ 3 years after planting. You can make full use of the open space 30 ~ 50 cm away from the crown to interplant leguminous crops or leguminous green manure and pasture. In order to realize "planting in a short time and cultivating the garden in the garden", but be careful not to interplant cassava, sugarcane, bananas and other crops.

Second, timely and appropriate fertilization is generally about 20 days after planting, and fertilization begins when new roots begin to grow. To achieve "three fertilizers for one branch", that is, apply 1 time again 25-30 days before the shoot is left, apply 1 time before the shoot is left, and apply 1 time after the new shoots sprout. Fertilization should master the principle of "diligent application and thin application". With the increase of crown and tree age, the number of fertilization can be reduced, while the amount of fertilization can be increased appropriately. For young trees 65,438+0 years before production, attention should be paid to cultivating large, neat and robust spring shoots, controlling late autumn shoots, preventing excessive nutrient growth and affecting flower bud differentiation, and achieving heavy spring fertilizer, stable summer fertilizer, excellent autumn fertilizer and controlled winter fertilizer.

Third, shaping and promoting shoots, cultivating early fruiting, high yield and stable crown 1? Short stem shaping, adjust the main branch: young trees with single stem and high main branch can be shortened by 20 ~ 25 cm above the root neck to promote multi-branching. Main branches with uneven density and unreasonable branching angle can be adjusted by pulling wires. Long branches should be smoothed or cut short, and long summer and autumn shoots should be picked properly. 2? Wipe the buds in time to promote bud retention: according to the bud retention period, wipe off the full buds (buds below the main branches), adventitious buds and overgrown branches in time, and adopt the method of "removing the early buds and keeping the whole ones, removing the weak ones and keeping the strong ones", so that about 70% of the plants in the whole garden and 70% of the base branches of the whole plant will keep buds when new buds sprout, making the new shoots neat, abundant and robust. It is generally required to leave a tip 3 ~ 4 times a year.

Fourth, improve soil and promote root system development. After planting honey pomelo, it should be improved according to the topography, landform and soil conditions in the park. Pomelo orchards on hillsides and hills should be deepened year by year, and organic fertilizer should be applied to continuously improve the soil. Reaming, digging and soil improvement can be carried out all year round. Generally, a ditch with a width of 0.3 ~ 0.6 m and a depth of 0.8 ~ 1 m is opened in the hanging part of the crown, and the length of the ditch depends on the crown size. The deep ditch is divided into 3 ~ 4 layers, and 30 ~ 50 kg of soil miscellaneous fertilizer (weeds, garbage, straw, manure) is buried. According to the soil quality, clay infiltration with sand and sand infiltration with mud, the scope of soil improvement will be expanded year by year until the whole park is completed. Low-lying flat pomelo orchard, through deep application of organic fertilizer and exotic soil, reducing groundwater and other measures, to create a deep, loose, breathable, water and fertilizer conservation soil environment.
