How is buckwheat grown? Buckwheat efficient planting technology
At present, most people pay more and more attention to the quality of life. For example, in the main food to eat, they advocate health and nutrition. The buckwheat that we introduce today is a food that can meet the basic nutritional needs of human beings and has high medicinal value. First, the cultivation technology of buckwheat 1. Water demand 300~600 ml/year. 2. Temperature Not higher than 32C, frost-free period is more than 100 days. 3. Elevation More than 1500 meters. The growth period of buckwheat is 90-220 days. The growth period is related to the sowing time and the local climatic conditions. Generally, the earlier the planting period, the longer the growth period. The planting requires the local frost-free period to be more than 100 days, the altitude is more than 1500 meters, the precipitation is more than 300mm, and the highest temperature. Not higher than 32 degrees. 4. Planting basic preparation before sowing The bottoming fertilizer + soil preparation needs to determine the sowing time according to the local climatic conditions. It is best to spread the fertilizer (organic or inorganic or mixed) evenly in the ground one week before sowing. The ground soil is 15-20 cm deep, if there is The root or plastic film left by the front sputum should be thoroughly cleaned to avoid affecting sowing and buckwheat growth. It is recommended to determine the amount of base fertilizer according to soil testing conditions. If the soil is relatively poor and there is no soil testing condition, 40-45 kg of sulfur-based compound fertilizer should be applied per mu (required compound fertilizer nitrogen ratio of 15:15:15 or higher). 5. Seeding machinery Using a planter that sows flax crops, the planter can adjust the amount, sowing depth, and row spacing. Seeding with a single leg (human + animal) seeding é•‚. 2-leg or multi-leg seeder with semi-mechanical walking tractor or tractor. The amount of seed per acre is 400g. The line spacing is controlled at 45-50 cm. 6. Seeding depth The sowing depth is 1-2 cm. 7. Seeding method Machine broadcast. Other notes: Before planting, you need to prepare the seed dressing materials, millet or millet. If you need to use the millet, you need to fry in advance. The ratio of seed to seed dressing material is 1 part of seed and 2 parts of millet (millet), or the amount of seeding material should be determined according to the commissioning situation. The amount and sowing are even. Special attention: 3-10 days after sowing, pay close attention to the growth of young shoots or seedlings and the situation of underground pests. If it is seriously harmed by underground pests, it is necessary to consider secondary sowing. 8. Field management (1) Management of fertilizer It is recommended that the base fertilizer be applied at one time without topdressing. If the symptoms of lack of fertilizer are found in the later stage of growth, the nitrogen fertilizer can be applied up to 15 kg per mu. (2) Water management Mainly with drought as the main. 9. Pest Management Underground pests are the main pests in the process of buckwheat planting. Among them, the scarabs are the most serious. The buckwheat seedlings that have just sprouted or unearthed are vulnerable to a variety of underground pests. In severe cases, they can cause the whole army to be destroyed. Understand the situation of underground pests in the plot. If the underground pests are serious, it is necessary to apply pesticides to kill underground pests during planting. Other common pests are cockroaches. When buckwheat grows to 50 cm or more, it starts to damage leaves or inflorescences. The cockroaches are relatively concentrated and often gather on several buckwheat. The easiest way is to observe cockroaches and artificially capture. . Diseases are common with leaf spot disease, and no economic loss has been reported. 10. Valerian After the buckwheat seedling grows to 10 cm, it can be combined with the first seedling to start the first grass. Generally, the buckwheat grows to 50 cm or more and needs hoeing 1-2 times. 11. Miao Miao When the buckwheat seedlings are 10 cm, the seedlings can be started, and the plant spacing requirement is about 25 cm. 12. Petri Since the height of buckwheat can reach more than 2 meters, from the second weeding, it is necessary to consciously cultivate the roots to make the roots more stable and prevent late lodging. 13. Transplanting (replanting) If the seedlings are found to be incomplete after emergence, the seedlings can be transplanted when the seedlings grow to 15-20 cm. The transplanting should be done after the rain or other water supply. 14. Harvesting (1) Mature standards The standard for the ripening of buckwheat is external viewing, the leaves turn yellow and red, the leaves mostly fall off, the dry begins to dry, and the seeds have no moisture after using the nail file. (2) Harvesting method At present, there is no buckwheat harvester in China. It is recommended to use the sickle to harvest manually, cut the buckwheat stalks, or smash the ears by hand. After harvesting, put them in the field or threshing ground to dry, or you can thresh in time. (3) Threshing Use four separate thresher machine to threshing, need to dry in time after threshing. Farmers who do not leave the machine need buckwheat to dry and then manually beat or crush. (4) drying It is best to choose a place away from sand and gravel for drying, so as to avoid sand and stone mixing. (5) Clearance After drying, use a fan to blow off the broken leaves or flats, then you can bag (6) Storage Need a cool, dry, ventilated, no rat. The above is the buckwheat planting technology that Huinong.com has compiled for you. If you feel that it is not bad, please continue to pay attention to this site.
