What are the key points of buckwheat cultivation techniques?
Buckwheat has a short growth period, generally maturing in 60-80 days. The key points of high-yield buckwheat cultivation techniques are: 1. Fine land preparation. Buckwheat seedlings have weak emergence ability, so attention should be paid to fine land preparation to create an environment conducive to seedling growth and development, so as to ensure full stands and strong seedlings. 2. High-quality sowing. Buckwheat is sown around the Start of Autumn...
Buckwheat has a short growth period, generally maturing in 60-80 days. The key points of high-yield buckwheat cultivation techniques are:
1. Fine land preparation. Buckwheat seedlings have weak emergence ability, so attention should be paid to fine land preparation to create an environment conducive to seedling growth and development, so as to ensure full stands and strong seedlings.
2. High-quality sowing. Buckwheat is sown around the Start of Autumn; sweet buckwheat can be sown up to the End of Heat, with a sowing rate of 3.5 kg per mu. Do not use old seed kept from the previous year. Before sowing, seeds can be soaked in warm water at 30°C-40°C for 10-15 minutes before sowing, which has a significant effect on earlier emergence and on strong seedlings.
3. Skillful fertilization. Buckwheat has a short growth period, so base fertilizer should be the main focus, applying sufficient basal fertilizer, applying topdressing early, and applying phosphorus and potassium fertilizer appropriately. Topdressing should be applied according to seedling condition, and should not be applied too much or too late, so as to avoid delaying flowering and seed setting and causing lodging later. During the flowering period, foliar topdressing with potassium dihydrogen phosphate, or trace elements such as boron, molybdenum and manganese, has a clear yield-increasing effect.
4. Scientific management. When seedlings are 7-10 cm tall, thin them in time in combination with intertillage and weeding. The second intertillage should be combined with earthing up to promote the development of adventitious roots. Intertillage and weeding must be completed before flowering.
5. Pay attention to drought resistance and drainage of waterlogging.
6. Timely harvest.
