Quinoa is widely cultivated in the north of Shanxi Province. It is a very old crop planted in alpine mountains. It is also the main food crop for farmers in Jinbei. Buckwheat straw is also a good forage for livestock. The following describes the high-yield cultivation techniques of dryland buckwheat.
   Choose excellent varieties. Excellent varieties are the main route of high yield. It is necessary to promote and lay out fine varieties according to local conditions, and according to the characteristics of dry land, select varieties with drought tolerance, disease resistance, cold resistance and high yield potential.
   Autumn machinery deep ploughing. After the harvest of the big autumn crop, the machine is deeply ploughed, and the land of the chestnut soil is shallow and the depth of the chestnut soil is about 15 cm. It is advisable to cultivate 20-25 cm in depth on the beach and in the wetland . At the same time, in the early Spring, the best effect of the suppression of the top of the roof, to reach the ground without a pull, on the virtual and real, play a role in protecting the soil.
   The crop is down. The main rotation methods are: dry slope: potato - flax - pea - buckwheat - potato 4 years of rotation .
   Dry land: soybean - buckwheat - flax - potato three-year rotation system.
   Sowing at the right time. Whether the sowing time is appropriate has a greater impact on the yield of buckwheat. General naked oats sown from early May, has been extended to the end of May, early-maturing varieties of the latest special can be delayed until late June.
   The sowing depth is generally about 5 cm, and the early sowing should be appropriate and deeper. The late sowing should be appropriate and shallow, and the drought and rain and the bad mood should be appropriate.
   The group structure is reasonable. Dryland buckwheat should determine the number of panicles to be reached based on soil fertility and yield targets. In general , 10 kg of seed is planted, and 250,000 to 300,000 seedlings per mu . In the land with higher fertility, the amount of sowing can be increased by 112 kg.
   Scientific fertilization. Quality manure applied per acre 1500 kg, 5 kg of DAP and sowing seeds mixed together, to take the rain jointing stage dressing, generally acres to recover 10 kg of urea.    Â
