How to grow olives
Olive is a fruit tree with high economic value, and its fruits can be used to extract oil or be eaten directly. In recent years, with the popularity of healthy diets, the demand for olive oil has continued to increase, and olive cultivation has also become a hot topic. This article will introduce the methods of growing olives in detail, and combine it with the hot topics and hot content on the Internet in the past 10 days to provide a reference for growers.
1. Basic conditions for olive cultivation
Olives are suitable for growing in warm and dry climate conditions and do not have high soil requirements, but loose, well-drained sandy loam is preferred. The following are the basic conditions for olive cultivation:
| Conditions | request |
|---|---|
| climate | The annual average temperature is 15-20℃, and the lowest temperature in winter is not lower than -7℃ |
| soil | pH value 6.5-8.5, well drained, rich in organic matter |
| light | The duration of sunshine throughout the year is no less than 2,000 hours |
| Moisture | Annual precipitation is 500-800mm, avoid water accumulation |
2. Steps of growing olives
1.Seed selection and seedling cultivation
Choose olive varieties suitable for local climatic conditions, such as 'Foao', 'Laixing', etc. Seedlings can be propagated by seeds or cuttings, among which propagation by cuttings is more common and has a higher survival rate.
| Reproduction method | Advantages | Disadvantages |
|---|---|---|
| seed propagation | Low cost and suitable for large-scale seedling cultivation | The growth cycle is long and the varieties are easy to mutate. |
| Propagation by cuttings | Maintain variety characteristics and grow quickly | High technical requirements and high cost |
2.Land preparation and planting
Before planting, the land needs to be plowed deeply and sufficient base fertilizer applied. The appropriate planting time is spring or autumn, the spacing between rows is generally 5m×5m, and 25-30 plants are planted per acre.
3.Field management
Olive tree management includes watering, fertilizing, pruning and pest control. Olives are drought-tolerant, but water supply is required during the fruit expansion period. Fertilization is mainly based on organic fertilizers, with a small amount of chemical fertilizers. Pruning mainly removes diseased and weak branches and overly dense branches to keep the crown of the tree ventilated and light-transparent.
| management measures | Specific operations |
|---|---|
| watering | Water once a week during the seedling stage, and for adult trees depending on weather conditions. |
| fertilize | Apply organic fertilizer every spring, and topdress phosphorus and potassium fertilizer during the fruit expansion period. |
| pruning | Prune diseased and weak branches in winter and thin out overly dense branches in summer |
| Pest and disease control | Common diseases include anthrax and insect pests include olive fruit fly, which requires timely spraying |
4.Harvesting and processing
Olive fruits generally mature from October to December, so they need to be handled with care during harvesting to avoid damage. The harvested fruits can be used for oil extraction or pickling.
3. The combination of hot topics in the past 10 days and olive cultivation
1.Impact of climate change on olive cultivation
Recently, global climate change has become a hot topic. Frequent extreme weather events pose new challenges to olive cultivation. Growers need to pay attention to local weather forecasts and take disaster prevention measures in advance.
2.The rise of organic farming
As consumer demand for healthy food increases, organic olive cultivation is gaining attention. The use of organic fertilizers and biological control technology can improve the quality and market competitiveness of olives.
3.Application of smart agricultural technology
Smart irrigation systems and drone monitoring technology are gradually being applied to olive cultivation, helping growers improve management efficiency and reduce production costs.
4. Summary
Olive cultivation is a long-term investment that requires growers to master scientific cultivation techniques and adjust production strategies based on market demand. With proper seed selection, careful management and keeping up with industry hot spots, olive farming can become a lucrative business.
