When should buckwheat be planted and dug out?

Allium is a perennial herb belonging to the genus Allium of the Amaryllis family. Its edible part is mainly its bulb, which is usually used for pickling or cooked food. It tastes spicy, tender and refreshing, with a unique fragrance, similar to both leeks and garlic. So when should leeks be planted and dug out? Let’s take a look below.

1. When should buckwheat be planted and dug out?

Buckwheat is suitable for planting in autumn, specifically from mid-September to late October. The temperature is suitable at this time, which is conducive to the growth of radish. In northern regions, sowing or transplanting can also be carried out in spring from March to April. Chinese garlic sprouts are usually harvested from late May to June of the following year. The specific time varies depending on the planting time and growth conditions.

2. The growth environment of buckwheat

Growth environment requirements

The goldenrod prefers a cool climate, and the optimal growth temperature is 15-19℃. It has low light requirements and is shade-tolerant, but requires longer light exposure time when the bulbs develop. In addition, buckwheat is not drought-tolerant or water-tolerant, and the soil needs to be kept moist during its growth period. It is best cultivated in loose, fertile, well-drained sandy loam.

3. Key points of cultivation technology of buckwheat

1. Soil selection and treatment

Avoid continuous cropping with lily crops, and choose sandy loam or rice fields for crop rotation. Combine land preparation with base fertilizer application, with organic fertilizer as the main ingredient, and apply 1,000 kg of decomposed human and animal manure plus 10 kg of triple compound fertilizer per mu. After land preparation, make ridges 85 cm wide and furrows 20 cm wide.

2. Variety selection

Choose varieties that are disease-resistant, high-quality, high-yielding, stress-resistant and widely adaptable, such as long-stalked leek and large-leaf leek. Choose bulbs that are free of pests, diseases, wounds, and root rot for seeds.

3. Sowing and planting

With a spacing of 15 cm between plants, place the buckwheat heads diagonally in the planting ditch and cover them with 2 cm thick fine soil. Generally, 10,000 to 12,000 buckwheat heads are planted per mu, with 2 buckwheat heads planted in each hole, and the seed rate per mu is about 90 kg. After sowing, water thoroughly to facilitate germination.

4. Fertilizer and water management

On the basis of applying sufficient base fertilizer, pay attention to the application of seedling-promoting fertilizer, pre-winter fertilizer and spring fertilizer. The soil needs to be kept moist during the growth period of buckwheat. Water should be replenished in time in case of drought, and care should be taken to prevent waterlogging in the fields during the rainy season.

5. Harvesting and seed saving

Young buckwheat heads for fresh consumption can be harvested from January to April, when the plants are fully grown and have a fresh and tender texture. For seed preservation, the plants can be left until the end of August or early September, when the aboveground part of the buckwheat heads withers and can be dug up.

4. High-yield planting and management techniques for buckwheat

1. Reasonable crop rotation and soil treatment

Implement water-land crop rotation to reduce the sources of pest and disease infection. For perennial dryland, soil treatment should be carried out by spreading 20 to 25 kg of lime per mu in combination with land preparation.

2. Scientific topdressing and irrigation

Start applying fertilizer after seedlings emerge, once every 15 to 20 days. Keep the soil moist during the growing season and water every 3 to 5 days if there is no rain. Pay attention to drainage after heavy rain to prevent long-term flooding.

3. Field management

After the main tillers of buckwheat emerge from the soil, combine inter-row cultivation and weeding with shallow soil loosening to promote uniform seedlings and stump division. The seedlings should be transplanted with soil in places where there are no stumps. Attention should be paid to drought resistance and frost prevention in winter.

5. The deliciousness and health value of buckwheat

Buckwheat is not only easy to grow, but also delicious. It can be used for stir-frying, making soup, and pickling vegetables to increase the flavor of the dishes. Pickled buckwheat pickles are especially popular among people. They have a strong buckwheat aroma and a sweet and sour taste. In addition, Chinese buckwheat has the effects of detoxification and promoting bowel movement, and has a good health care effect on the stomach and intestines.

Mastering the planting method and optimal planting time of buckwheat is the key to obtaining high-yield and high-quality buckwheat. Through reasonable cultivation management and scientific topdressing irrigation, you can easily harvest delicious buckwheat and enjoy its unique flavor and health value.
