Sweet orange pomelo tree strong, crown round head type, branch tip apical dominance is obvious, sprouting branching force is strong, branch, leaf morphology close to the Wenzhou mandarin orange, the branch has a small thorns, the climatic period of the Wenzhou mandarin similar to the young and thriving tree with leafy flowering branches accounted for more than 90% of the amount of flowers. The number and length of leafy flowering branches are higher than other varieties of citrus, the longest length of leafy flowering branches reaches more than 35 cm, the number of leaves reaches more than 13, the spring and autumn tips as the main fruiting mother branch, inside and outside the crown of the fruiting branches can be fruiting, from July to late October for the period of fruit expansion, the end of November - the first half of December the fruit is ripe.
(2)Adaptability and Resistance
Sweet orange pomelo has strong resistance to cold, ponkan, huyu, wenzhou mandarin suitable planting area are suitable for planting, cold resistance is stronger than ponkan, can be safely planted in Lishui, wenzhou, quzhou and other places in our province. Sweet orange pomelo is drought-resistant, barren, resistant to pests and diseases, and is suitable for planting in hillside areas.
Two, the main economic traits
(a) less nuclear or nuclear traits
Most of the fruits are nuclear-free, a small number of nuclear fruits about 3-5 seeds per fruit, at present, the nuclear-free single-plant preference is also being carried out, and the causes of its nucleus are also being studied.
(B) fruit character and storage
Fruit flat round, bun-shaped, neat, dignified, uniform fruit 230 grams. Fruit skin orange-yellow, fruit surface is not too smooth, peeling slightly difficult, but easy to hu pomelo. Fruit flesh orange-yellow, soluble solids content of 12% or more, soft and juicy, sweet, clear mouth, taste without acidity, orange and grapefruit aroma, fruit regardless of the size of the edible character is similar. the end of November to the first half of December ripening, single-fruit packaged in film, at room temperature under the conditions of storage to the end of May of the following year, the fruit market supply period in the citrus varieties to show expertise.
(C) early fruit and harvest
Highly connected to the Hovenia rootstock, medium-late maturity Wenzhou mandarin orange and other trees, a large number of results in the second year, the third year of the plant yield of up to 30-50 kilograms, mu yield of more than 3,000 kilograms.
Three, cultivation techniques
1, the choice of terrain conditions: ponkan, hu pomelo, wenzhou mandarin and other varieties of planting area can be planted sweet orange pomelo, to the elevation of 400 meters below, the soil layer is deep and fertile, north-south slopes for the best.
2, planting density and planting: if it is a hillside, to be dug into a wide 2.5 meters above the extent of the band, and then in the middle of the extent of the band to dig planting holes or planting ditch, 60 centimeters deep, 100 centimeters wide, in the planting ditch into the garbage and bar fertilizer or green Ai and other green manure, a layer of fertilizer a layer of soil, the uppermost layer of subsoil and organic fertilizers 15 centimeters apart, so that the root system does not come into contact with the direct fertilizers, each plant with Calcium-magnesium phosphorus fertilizer 0.5 kg and soil mix evenly, covered to the seedling root system, and let the root system layered stretch, tread can be. If planted on a sunny day, water thoroughly. If you take the disk dense planting, then mu planting 150 plants (1. 5 x 3 meters), if you take the forever fixed planting, then mu planting 75 plants ((3 x 3 meters). Every fall from late September to early November and spring from mid-February to the end of March can be planted.
3, fertilizer: with ponkan, wenzhou mandarin and other varieties, compared to the number and quantity of pleas more, because of its flowers, results in a large amount of fruit, fruit and large, consume nutrients are also large. Young trees linked to the spring, summer and autumn tips of the pumping, the year the top of the strong tip of the fertilizer 5-7 times, that is, 3-August monthly Shi once, 9-October stop, to avoid the pumping of the late autumn tips, and then apply a winter fertilizer, depending on the size of the tree per plant year uniformly urea 0. 2-0. 6 kg, potassium sulfate 0. 2-0. 2 kg, urea 0. 2-0. 6 kg. 6 kg, potassium sulfate 0.1-0.3 kg, 0.2 kg of phosphate fertilizer. Fertilization of fruit-bearing trees 4-5 times a year, fruit harvesting fertilizer 1 time, spring pre-bud fertilizer 1 time, strong fruit to promote fertilization 2-3 times, the amount of fertilizer, respectively, 30%, 20%, 50%, mu of 2500-3500 kg of the garden, per mu of annual application of 100 kg of urea, 150 kg of calcium phosphate, 150 kg of potassium sulfate, borax, 150 kg of potassium sulfate, 0.1-0.3 kg of phosphorus fertilizer, 0.2 kg. Potassium sulfate 150 kg, 3 kg of borax, 100 kg of cake fertilizer or bar fertilizer 1000 kg, nitrogen, phosphorus, potassium ratio of 1.0: 0.5: 0.8.
4, flower and fruit management: flower amount of the year without the need to protect the flowers and fruits, flower amount of the year can be used in the year of the small amount of Jiuji 1 gram of dissolved in alcohol mixed with 20-25 kg of water, in the flower Xie 2 / 3 for Fruit preservation, sweet orange grapefruit single fruit weight is large, leaf fruit ratio should be maintained at 40:1 or so is good, excess fruit can be sparse, the first sparse disease and insect fruit, deformed fruit, dense fruit, after the sparse excess fruit, and the proposed sparse fruit after the fulfillment of the bag, in order to produce pollution-free high-quality fruit.
5, branching pruning: due to excessive results caused by the early decline of the tree branches and branches should be short cuts to promote the development of new shoots, in order to ensure that the annual harvest and stable production, too dense branches should be thinned out to stay strong; tree rich and strong fruit trees, cut out some of the interspersed branches, concurrently with the growing branches, serious pests and disease branches, hidden branches can be.
6, pest control: with ponkan, wenzhou mandarin pest control approach is more consistent, to red spider, rusty wall lice, mealybugs, aphids, leaf miner moths, scab disease as the focus of integrated prevention and control, winter with 0.5-1 degrees of stone sulfur compound to do a good job of clearing the garden, March-October based on the occurrence of pests, do a good job! Suitable for scientific control, commonly used pesticides are Bordeaux liquid, tolbutamide, tin, acarbophos, oxalic acid, lexapro, imidacloprid, methomyl and so on. A biological characteristics
(a) growth and fruiting habits
Sweet orange grapefruit tree strong, crown round head type, branch tip apical dominance is obvious, sprouting branching force is strong, branch and leaf morphology close to Wenzhou mandarin orange, branches with small thorns, climatic period with the Wenzhou mandarin similar to the young and thriving tree with leafy branches accounted for more than 90% of the amount of flowers.
