An Analysis of the Latest Requirements for Navel Orange Growing Conditions
Navel orange is a kind of sweet orange variety of the Rutaceae family, and its planting area in our country is very large. In our country there is a very large planting area, the economic life of the navel orange is very long, the fruit has high nutritional value, and its economic value is relatively high. However, when we plant navel oranges, we need to take the growing environment of the navel orange into consideration. So what environment does planting navel oranges require? Today, the editor has brought you the growing environment for navel oranges. Let's take a look together below!
1. Moisture requirements
When planting navel oranges, the first thing to consider is the moisture requirement. The navel orange fruit itself contains a very large amount of water, so when we plant navel oranges, the soil layer thickness must not be less than 80 cm, and it is best to keep it above 1 m. At the same time, the annual rainfall in the planting area should stay above 1000 mm. When planting, it is not suitable to plant in farmland, because the groundwater level of farmland is very high. In summer, when there is a lot of rain, waterlogging is likely to occur, which is very unfavorable to the growth of navel oranges. If it must be planted in farmland, then deep furrows and high beds should be the main planting method, but it is best to plant on hilly slopes.
2. Soil requirements
The growth ability of the navel orange is very strong, and its requirements for soil are not very strict. Whether it is red soil or alluvial soil and so on, it can adapt normally and can live on most soils. However, differences in soil will have a certain impact on the yield and quality of navel orange fruit. So when we plant navel oranges, we should mainly use soil that is deep, sufficiently fertile, highly permeable, and soft. The soil pH value should be kept at around 6-6.5, so sandy loam soil is best. If red soil is properly improved, it can also be used to plant navel oranges.
3. Climate requirements
The growth of navel oranges still has certain requirements for temperature, and navel oranges are suitable for growing in an environment with an average annual temperature of around 20 degrees. During their growth period, if the temperature is greater than or equal to ten degrees, then the annual accumulated temperature should be kept at around 4600-4700 degrees. The lowest temperature in winter must not be lower than minus five degrees, and by January, the average temperature should be kept above 8 degrees. Then, for air humidity, it should be kept at around 70%-75%. Maintaining a relatively large temperature difference between day and night and a relatively long frost-free period is very favorable to the growth of navel oranges.
4. Orchard site conditions
The orchard site for planting navel oranges should be set up on gentle slopes of around 25 degrees. Ensure sufficient sunlight, deep soil, and normal drainage and irrigation, minimize investment as much as possible, and ensure convenient management. If planting on flat land or in paddy fields, then deep furrows and high beds should be the main planting method to improve drainage capacity. Planting on flat land is relatively convenient to manage, with sufficient water sources, and is very favorable to the development of the navel orange tree roots. However, its ventilation and sunlight are not as good as mountain planting. When building the orchard, pay attention to the groundwater level to avoid waterlogging. In addition, transportation also needs to be taken into consideration.
The above is a brief introduction to the growing environment for navel oranges. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
