How to grow yams
In recent years, with the rise of healthy diet, yam has attracted much attention due to its rich nutritional value and medicinal effects. Many families and farmers have begun to try to grow yams, but they still have questions about their cultivation methods. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you to the cultivation methods of yam in detail and provide structured data for reference.
1. Basic conditions for yam cultivation
Yams are suitable for growing in a warm and humid environment and have certain requirements for soil and climate. The following are the basic conditions for yam cultivation:
| Conditions | Specific requirements |
|---|---|
| climate | The suitable temperature is 20-30℃ and the annual precipitation is 800-1500 mm. |
| soil | Loose, fertile, well-drained sandy loam soil, pH 6.0-7.0 |
| light | At least 6 hours of sunlight a day |
| Crop rotation | Continuous cropping is not suitable and an interval of more than 3 years is required. |
2. Steps of yam cultivation
The cultivation process of yam can be divided into the following steps:
1.Seed selection treatment: Choose healthy and disease-free yam seed blocks. Each block weighs about 50-100 grams and has 1-2 bud eyes. Soak and disinfect with carbendazim before planting.
2.Land preparation and fertilization: Deep plow the soil 30-40 cm, apply 2000-3000 kg of decomposed organic fertilizer and 50 kg of compound fertilizer per acre.
3.Planting method:
| Planting method | Specific operations | Advantages and Disadvantages |
|---|---|---|
| Flat border planting | Dig trenches at 80cm between rows and 30cm between plants, and lay the seed blocks flat. | Easy to manage, average output |
| High ridge planting | The ridge height is 30cm, and the seed blocks are inserted diagonally. | High output, labor intensive |
| trellis cultivation | Set up a 1.5-2m high bracket | Good quality, high cost |
4.Field management:
-moisture management: Keep the soil moist but not waterlogged, and pay attention to drainage during rainy season.
-Top dressing: Apply potassium fertilizer in the middle growth period to promote tuber enlargement.
-Pest and disease control: Mainly used to control anthracnose, root rot, aphids, etc.
3. Harvest and Storage of Yams
The growth period of yam is generally 6-8 months. The key points for harvesting and storage are as follows:
| Project | Technical requirements |
|---|---|
| harvest time | After the above-ground parts have withered and turned yellow, harvest them on sunny days. |
| Harvesting method | Dig carefully to avoid damaging the tubers |
| storage temperature | 10-15℃ is appropriate |
| Storage humidity | Relative humidity 80-85% |
4. Frequently asked questions about yam cultivation
According to recent online discussions, the following are some of the most concerning issues in yam cultivation:
1.Low germination rate: The main reason is poor quality seed blocks or improper storage. It is recommended to choose healthy seed blocks and disinfect them before planting.
2.tuber deformity: Mostly caused by soil compaction or improper fertilization, the soil needs to be improved and organic fertilizer added.
3.The output is not high: It is related to variety selection, cultivation density and management level. It is recommended to choose high-yielding varieties and plant reasonably densely.
5. Market prospects of yam
Judging from recent Internet hot spots, the market demand for yam and its processed products is strong:
| product type | Market characteristics | Price range (yuan/kg) |
|---|---|---|
| Fresh yam | Demand is stable, seasonal fluctuations | 6-15 |
| yam powder | Demand for health food is growing rapidly | 40-80 |
| yam tablets | Snack food market expands | 30-60 |
To sum up, yam cultivation is a highly technical agricultural activity that requires correct planting methods and management techniques. As people's demand for healthy food increases, yam cultivation has good development prospects. I hope that the introduction in this article can help you successfully grow high-quality and high-yielding yams.
