Buckwheat has a short growing period (only 70--80 days), strong adaptability, high nutritional value, and has always been used as an excellent crop for filling, disaster relief, and filling up. Production experience shows that the following four points should be taken when planting good buckwheat:
The first is timely sowing. Buckwheat has the characteristics of "early sowing three days without seeding and late sowing with three days of Xiasha". Practice has proved that the sowing time of autumn quinoa is "early autumn and early autumn, Bai Lu late, the Department of Justice is the time."èž The larger wheat leaves and the slim roots should be sown in the soil after being soaked in warm water 30--40 degrees Celsius for 10 minutes behind the smashed soil rakes and squat flats. Seed 5 kg per 667 square meters and cover with 3 cm of shallow soil. about. In this way, not only can increase the germination rate, promote early emergence, growth and orderliness.
The second is to increase fertilizer material. Increasing phosphorus and potassium fertilizers in buckwheat can significantly increase yield. According to the characteristics of the growth period of autumn buckwheat, the base fertilizer should be the main, 667-1000 m of pig manure per 667 m2, 15-20 kg of phosphate fertilizer, 30 kg of vegetation ash.
The third is to grasp the field management. Barley fields should be open to prevent waterlogging. After sowing, in case of drought, it is necessary to moisten the irrigation to ensure the whole seedlings. If there is no irrigation condition, dilute manure water should be poured in the morning and evening before the emergence, and the fertilizer should be increased and the seedlings should be improved. Buckwheat seedlings grow slowly and prone to weeds. When the seedling height is 6--8 cm, it should be cultivated and weeded, and the weak seedlings should be removed. The second cultivator before flowering, and the shallow soil culture, to promote root development. In flowering to fruiting period, every 667 m2 is sprayed with 0.5 kg urea, 200 g of potassium dihydrogen phosphate, and dissolved in 60 kg of water to spray 1--2 times to prevent premature defertilization.
The fourth is auxiliary pollination. Buckwheat in the natural state, the seed-bearing rate does not exceed 20%. Therefore, bees should be stocked during flowering to pollinate or artificial pollination should be conducted 2 to 3 times. Artificial pollination method is to use a nylon rope, two people each holding one end, so that the rope gently dragged over the top of the plant, in order to vibrate the flowering branches, promote pollen drift, in order to vibrate the flowering branches, promote pollen drift, pollination.
