Many people talk about oranges and oranges separately, but oranges are also a kind of oranges. At present, ice sugar oranges, navel oranges, blood oranges and other varieties are very popular on the market, so if you plant oranges, which varieties of orange seedlings are the best?

What is the best variety of orange saplings?

1. Taroko Blood Orange

The tree potential is moderate, the crown is round, medium, irregular: the fruit is Obovate or short oval, the pedicel has obvious grooves, the single fruit weighs about 150 grams, the fruit is orange-red, smooth; the flesh is dark, all purplish red, crisp, juicy, sweet and sour, rich aroma, nearly seedless, high quality; the fruit matured from January to February the following year, resistant to storage. Taroko Blood Orange, as a late-maturing sweet orange, is an excellent orange variety vigorously promoted in China.

two。 Newhall navel orange

Newhall navel orange is a fresh-selling variety with beautiful appearance, excellent meat quality and good commercial quality. It is native to the United States and is made from the Washington navel orange bud of Duarte, California.

3. Gannan navel orange

Gannan navel orange fruit is large, bright orange, bright, clean and beautiful, with an edible rate of 85%, crisp and tender meat, cinder, sweet and fragrant flavor, and more than 55% fruit juice.

4. Australian finger orange

After grinding the finger orange into a sticky substance, wipe the face every day, which can effectively dispel acne and spots and keep the skin white and delicate.

[4] it is native to Hongjiang City, Hunan Province, with more cultivation in Hunan, and a small amount in Sichuan, Chongqing, Guizhou, Yunnan and Liangguang.

2. Methods of raising orange seedlings

1. Sowing quantity

There are more than 2000 orange seeds per jin. Because the seeds are polyembryonic and may send out 2 or more buds, it is possible to produce more than the number of seedlings per jin of seeds. Of course, this is only possible in theory, but in practice it is subject to various conditions. generally, when sowing in winter, it can grow up to about 2000 seedlings per jin, while sowing in spring can produce 2500 seedlings per jin. This is because overwintering sowing may encounter low temperature chilling injury, affecting the emergence rate and seedling rate. If the overwintering sowing uses the greenhouse facility to raise the seedling, or the small arch greenhouse covers the seedling, it can improve the sowing quality and the emergence rate. The soil quality and management level of the nursery bed have a great impact on the emergence rate. Many nursery households will cause serious losses because of the seedbed and management problems, and the emergence rate may be less than 50%, or even lower.

two。 Sowing at the right time

Orange rootstocks can be sown in autumn, winter and spring, but they should be cautious in summer. The temperature is high and the sunshine is strong in summer, which is easy to cause high temperature damage and affect the normal growth of seedlings. Seed soaking and disinfection should be carried out before sowing. At the same time, soaking seeds for 2 hours can increase the germination rate and reduce seed loss. Fresh seeds can be sown in areas where the average temperature in winter is not low and the frost-free period is long. The fresh seeds can be sown after drying the surface moisture. Sowing fresh seeds in autumn can prolong the growth time and early grafting. Sowing density, 100-150 jin per mu. Many farmers do not pay much attention to sparse sowing and uniform sowing, grab a handful and sow it casually, resulting in uneven density of seeds, which will not only affect the quality of seedlings, but also cause seed waste. In order to sow evenly, sowing should be weighed separately. For example, if a piece of land has a 10-car seedbed, the seeds can be divided into 10 equal parts before sowing, and one part can be sowed in each box, and the first part can be subdivided into 2 equal parts, which can be sowed back and forth twice in the same seedling bed, so it is easy to spread evenly.

3. Post-broadcast management

Greenhouse mulching cultivation can be beneficial to the healthy growth of overwintering seedlings. There are two kinds of plastic greenhouses: steel greenhouse and bamboo greenhouse. In order to improve the temperature of seedling bed, the method of covering small shed in greenhouse and covering plastic film can be adopted to improve the environmental temperature of seedling growth. If there is no facility coverage, after sowing in autumn, winter and spring, it is necessary to cover the plastic film for heat preservation and moisturization to promote its germination and growth. After one year of growth, the general plant height can reach 30ml 50cm, the seedling diameter can reach 4mm; in the second year, the plant height can reach 70Me 80cm, the diameter is about 8mm, the sapling is about 80cm thick and 40cm high is the best transplanting.

To sum up, it is all about orange saplings. You can choose varieties that are suitable for your local planting. I hope it can help you learn.
