Planting time of buckwheat

Buckwheat is a kind of miscellaneous grain with high nutritional value, which can be used to make noodles, sweet potato, cold noodles and other foods. So, when will buckwheat be planted? How do you plant it? The following is to introduce the planting time and method of buckwheat.

1. Planting time of buckwheat

Buckwheat can be sown from the end of March to the beginning of May in spring or from the end of July to early August in autumn. Autumn sowing should be earlier and not delayed. If it is a dry farming area in the north and an alpine mountain once a year, it is appropriate to sow in spring. If it is the winter wheat area of the Yellow River basin, it should be sown in summer. If it is south of the Yangtze River and coastal areas of Central and South China, it is appropriate to sow in autumn. If it is the southwest plateau, it is appropriate to sow in spring or autumn.

2. Planting methods of buckwheat

1. Sowing seeds

There are mainly broadcast, on-demand and broadcast, advocating broadcast. Because sowing and sowing seeds are uneven, it takes too much work to order. Narrow-row strip sowing and wide-row strip sowing are divided according to soil fertility and variety branching habits, with a width of 167cm to 200cm and a sowing area of 13cm to 17cm.

2. Seedling stage management

When sowing in case of drought, it is necessary to suppress and stabilize the soil in time, reduce the gap, and make it virtual and solid on the soil tillage layer, so as to facilitate the rise of groundwater and the germination of seeds. When there is rain or high soil water content after sowing, it will cause surface slabs, large buckwheat cotyledons and poor top soil capacity, and ground hardening will affect seedling emergence. Harrow can be used to break the hardening and loosen the surface.

3. Watering

Buckwheat is a typical dry farming, but its drought resistance is weak in the growth process, and the most water is needed in the flowering and filling stage. In China, spring buckwheat is mostly planted on dry sloping land, lack of irrigation conditions, and buckwheat growth depends on natural precipitation. In the areas with irrigation conditions in spring buckwheat area, in case of drought during flowering and filling period, buckwheat should be irrigated to meet the water requirements of buckwheat in order to ensure the high yield of buckwheat.

4. Fertilization

Buckwheat is a crop that needs a lot of fertilizer. in order to obtain high yield, sufficient fertilizer must be provided. for dry and barren land and alpine mountains, the application of fertilizer, especially nitrogen and phosphorus fertilizer is the basis of high yield of buckwheat. Fertilization should be based on base fertilizer, supplemented by planting fertilizer, topdressing as supplement, organic fertilizer as main, and inorganic fertilizer as auxiliary. The application rate should be scientifically mastered according to soil fertility basis, yield index, fertilizer quality and planting climate characteristics.

5. Ploughing and weeding

Mid-tillage has the effect of loosening soil, increasing soil permeability, storing water and preserving soil moisture, increasing soil temperature, promoting seedling growth, and eliminating the harm of weeds. The times and time of weeding in mid-tillage depend on the area, soil, seedling condition and the number of weeds. The first intertillage weeding was carried out in combination with inter-seedling thinning when the seedlings were 6-7 cm high. The second intertillage was carried out before the ridge closure of buckwheat, combined with topdressing and soil cultivation, with a depth of 3cm to 5cm.
