1. Which variety of red orange is better?
Red-orange causal meat is named after its blood-like color. It belongs to navel orange in essence, and has developed many flavors such as Taroko red orange, China red navel orange and rose red orange.
Taruko 1
It is cultivated by the offspring of nucellar system of Taroko navel orange. The fruit usually ripens in the last ten days of 65438+ 10. As a late-maturing sweet orange, it is an important fine variety to be popularized.
2. Moro people
Moro navel orange is a new member of navel orange family, among which the color is bright, the flesh is deep purple and the peel is orange-red.
3. Shan Zhi is hardworking
Sangji industrious red orange was discovered in Spain on 1929, with red skin, few seeds and sweet and soft flesh. Sangji industrious blood orange and Moro red orange have similar characteristics. It ripens in February, but if it is not harvested, it can stay in the tree until April and will not fall until the end of May. The orange peel is compact, with light yellow and reddish color. The pulp is orange with many bloody stripes.
4, rose red orange
Rose-red orange, also known as Rose-fragrant orange, has an obovate or short oval fruit with obvious furrows on its stalks. The single fruit weighs 200-250g, which is the larger crystal system in red orange. The fruit is smooth, and the peel and pulp are blood red when ripe. Fruit usually ripens in late October.
5, ruby blood orange
Also known as Ruby Red Orange, Safflower Orange and Hongbao Orange. Mediterranean countries mainly produce it, and China has cultivated it.
6. Red Evening Orange
Red Evening Orange was introduced for the "948" project. This variety has pink to red flesh, uniform color, special flavor in peel and pleasant flavor when peeling oranges. Excellent quality, good commodity, nearly round fruit, average single fruit weight of about 200-300 grams, high fruit setting rate, early production period, good storage resistance, and cold storage period of more than 4 months. As a new special variety, this variety has great popularization value.
Second, how can blood oranges be planted to achieve high yield?
1. Dig a fertilization pit with a length of 1 ~ 1.2m, a width of 40 ~ 50cm and a depth of 40 ~ 50cm at the outer edge of the fruit pit, and apply 20 ~ 30kg of green manure and weeds, pig manure and phosphate fertilizer10 ~/kloc-0 to each plant. Combined with deep application of organic fertilizer, deep tillage and soil improvement are carried out 1~2 times a year, and the deep tillage position is continuously rotated, and the deep tillage task of the whole garden is completed in 3~4 years.
2. Planting green manure in the open space between rows for two seasons, ploughing and weeding in the tree tray for 3~4 times every year, and covering the tree tray in the high temperature and dry season. In rainy season, the flat orchard should be ditched and drained.
3, 1~3-year-old trees, the purpose of fertilization is to enhance the vegetative growth of trees, promote the emergence of strong branches, and make them expand rapidly to form high-yield trees. The principle of fertilization is: apply fertilizer frequently and thinly, eat less and eat more meals, give priority to nitrogen fertilizer, and properly cooperate with phosphorus and potassium fertilizer. Spraying with 10~20% decomposed chaff manure (or biogas slurry) and 0. 1~0.3% urea or 0. 1~0.3% compound fertilizer every 15~20 days/time.
Apply "one branch and three fertilizers" to each new shoot, that is, fertilizer before germination (before germination 10 day), fertilizer for attacking shoots (when new shoots spread leaves) and fertilizer for strengthening shoots (after leaves turn green). Strive to shoot strong branches 3~4 times a year/kloc-0. Every time new shoots turn green, foliar fertilizers such as Lv Wang 1 1000 times or 0.2% potassium dihydrogen phosphate are added in combination with pests to promote the senescence of new shoots.
Plastics: In summer, citrus should adopt natural round-headed trees. Cut off the top of the trunk at a height of 30-40 cm and fix the trunk. After the new buds germinate, select 3-4 main branches with strong growth and uniform distribution, and the opening angle of the main branches is 40-45 degrees. There are 2-3 auxiliary main branches on each main branch, forming a good crown skeleton with strong bearing capacity.
Pruning: bud wiping and shoot control. When 1 batch of young trees planted in that year are mature, it is necessary to erase the scattered new shoots released early during the summer and autumn, so that the new shoots can be released evenly, so that the new shoots can be neat and robust, and the harm of liriomyza sativae and aphids can be reduced.
In the first half of May and July, strong fruit fertilizer was applied, mainly nitrogen and potassium combined with phosphorus fertilizer, accounting for about 35% of the whole year; Fruit fertilizer, weak trees and trees with more fruits should be applied before harvest, and base fertilizer should be applied to trees with less fruits after harvest, accounting for about 35% of the whole year. Organic fertilizer can be applied during this period. You can also apply it twice a year. After the fruit is picked, base fertilizer is applied before the spring shoots germinate. Apply organic fertilizer and half of chemical fertilizer at the same time throughout the year, and the remaining half of chemical fertilizer will be applied after the fruit is stable in July.
