Buckwheat has a short growth period, strong adaptability, moderate yield, and high nutritional value. It has always been used as a paddy and disaster-relief crop. In order to achieve a good harvest of buckwheat, the following points should be noted:
First, the election site preparation. Buckwheat bogey continuum, the former is best potatoes or glutinous rice dumplings. Buckwheat is a straight root crop, roots are not well developed, and the buds are soft. Therefore, sowing should be carried out before sowing, and fine soil preparation can create good environmental conditions for maintaining seedlings and seedlings.
Second, seed processing. Before sowing, it is necessary to dry the seeds for 2 to 3 days, and then soak seeds in warm water to soak seeds for 15 minutes in a warm water at 35°C to remove the floating pods, and then remove the remaining granules and dry them out. Seed dressing. Seed dressing method: First, take 1~5 kilograms of plant ash to soak in water for 1~2 days. Spray seeds with plant ash liquid one day before sowing, and sprinkle 1 kg of turf liquor with 10 kilograms of seed. The residue of the ash is mixed with the seeds and mixed well. After 3 to 4 hours, the seeds are not agglomerated and they can be sown, which can increase the yield. The second is to use 40% pentachloronitrobenzene powder 0.5 kg seed dressing 50 kg, can control blight, ringworm disease, brown spot and white mold.
Third, pay close attention to rush broadcast. Buckwheat grows in both a cool and cool environment and is frost-free. Seeding is too early and the early growth stage is susceptible to high temperatures; sowing is too late and it is susceptible to frost during the late growth period. The peasants' years of cultivation experience are: early autumn and early autumn, Bai Lu late, and the summer heat sowing is the time.
Fourth, increase fertilization material. Buckwheat is resistant to barren, but proper application of P and K fertilizers can significantly increase yield, but potassium chloride cannot be applied because chlorine ions can cause spot disease and lead to a reduction in yield. Mushi superphosphate 20 kg and urea 6 kg are used as base fertilizers, which are both economical and increase production. When applying, care should be taken to separate the chemical fertilizer from the seed and prevent burning of the seedling.
Fifth, rational close planting. Excessive density of buckwheat can affect production. The production practice has proved that it is appropriate to plant 3.5~4 kilograms per mu, and 14 to 160,000 plants per mu. The depth of sowing is 3~4 cm, and the thickness of earth covering is generally 3 cm. After sowing, if the soil is dry, you can press it again with wooden rakes;
Six, field management. It is necessary to loosen the soil in time to promote growth and development. During the three-leaf period seedlings, the seedlings are distributed evenly. When the seedling height is 9-10 cm, it is cultivated once every 10 days until the budding stage is closed. During the initial flowering period, 0.3% potassium dihydrogen phosphate solution and 0.1% ammonium molybdate or boric acid solution were sprayed. Flowers are pollinated at full flowering time, which is suitable from 8 to 10 o'clock in the morning. The method is to use a rope or a wooden rod to laterally move the plant 2 or 3 times, once every three days. Conditional farmers will store two boxes of bees for every 15 mu during the flowering period. Occurrence of insect pests in a timely manner, timely prevention and control of armyworm, grasshoppers, hook moths and aphids.
Seven, appropriate harvest. Before the frost falls, when 70% of the grains of the whole plant are dark brown, they should seize the time to harvest early and late, and tie or tie them up and place them indoors to let the buckwheat fully mature.
