To grow high-yielding buckwheat, you need to master these key cultivation techniques
As a relatively important food crop in China, buckwheat has a wide planting area and market demand in the country. Buckwheat has fairly high nutritional value, so its planting area is still expanding, and the demand for yield is also growing higher and higher. Now how to increase yield has become the main problem facing many farmers. So how should buckwheat be grown for high yields? Let's take a look together below!
1. Fine land preparation
Land preparation is an indispensable task before planting buckwheat. Because buckwheat needs crop rotation, we must first choose soil with sufficient fertility, normal drainage and irrigation, and the previous crop is best legumes. Then we should increase the intensity of land preparation, and shallow hoeing and shallow plowing should not be used. Because if land preparation is improper and the soil becomes too alkaline, it is very unfavorable to the growth of buckwheat. So we should prepare the land finely, improve the soil structure, eliminate harmful substances in the soil, improve soil permeability, create a good growing environment for buckwheat, and increase the seed-setting rate.
2. Reasonable sowing
Buckwheat is generally sown around spring and autumn each year. We should reasonably adjust the sowing time according to different regional environments. For example, if there is a high-cold phenomenon, then the sowing time should be appropriately advanced, and we should try our best to ensure that harvest can be carried out before frost arrives, preventing low temperatures from causing frost damage to buckwheat and reducing yield. The sowing method is generally mainly drilling and dibbling, and reasonable sowing can improve the germination ability of seeds, enhance the root growth ability of seedlings, and reduce lodging. Then control the sowing rate at 3kg/mu, and after sowing, do a good job of covering the seeds, improve the soil's moisture-holding capacity, and promote emergence.
3. Scientific fertilization
Many friends generally choose to lightly prepare the land after harvesting the previous crop and then start sowing, with neither deep plowing nor base fertilizer application. In this way, the nutritional needs of buckwheat growth cannot be fully met. To achieve high yields of buckwheat, sufficient base fertilizer must be applied, and topdressing must be done well. While ensuring sufficient base fertilizer, after the seedlings emerge, topdressing should be combined with intertillage about two times. Then, according to the growth stages of buckwheat, do a good job of topdressing. For example, during important periods such as the flowering stage and seed-setting stage, topdress in time to ensure sufficient nutrition. However, pay attention to the amount of nitrogen fertilizer and other fertilizers, which must never be excessive, to prevent excessive vegetative growth of buckwheat.
4. Artificial pollination
Buckwheat is a cross-pollinated plant. If it relies on self-pollination, the amount of pollen is insufficient, the pollination and seed-setting rate is also very low, and its yield will naturally be relatively low. So when planting buckwheat, we should pay attention to doing a good job of artificial pollination. Improve the pollination and seed-setting rate of buckwheat. When buckwheat enters the full flowering stage, start driving pollen on a sunny morning, lasting about 5 days. Alternatively, bees can be released for pollination. These can effectively improve the seed-setting rate, and as the seed-setting rate rises, its yield will certainly increase as well.
The above is a brief introduction to how to grow buckwheat for high yields. In addition to doing the above four aspects of work well, we should also strengthen management work, which can further increase yield and ensure high yields of buckwheat.
