There are 20 provinces and municipalities (autonomous regions) with large cultivated area of sunflower in China. Bayannaoer, a city known as "the granary on the plug". Bayannaoer is located in more than 40 degrees north latitude, with the Yellow River Basin flowing through it. The soil is fertile, especially suitable for planting crops and sunflower growth. According to statistics, 45% of the sunflower production in China comes from Inner Mongolia Autonomous Region, while 53% of the sunflower production in Inner Mongolia Autonomous Region comes from Bayannaoer. It can be imagined that the sunflower production in Bayannaoer is quite considerable. This is also the reason why Mengxin Food Co., Ltd. chose here

Methods of sunflower planting and site selection2021-03-05

Sunflower planting site selection method: sunflower cultivation should choose flat land, medium fertility, irrigation and drainage convenience, soil viscosity is relatively small plot. It is not suitable for continuous cropping. Peat soil is suitable for seed reproduction. Seed dressing with new high fat film before sowing can repel underground pests, isolate virus infection and improve seed germination rate

Sowing methods of sunflower2020-12-29

(1) When the soil temperature of 125px is 5 ℃, it can be sown. The basic principles of sowing date selection are as follows: first, according to the occurrence law of saline alkali, the seedlings should be sown early or late to avoid the damage of saline alkali; Second, spring sowing or summer sowing should be carried out according to the growth period of varieties; Thirdly, the sowing date should be adjusted according to the disease regularity to avoid the disease prone season; Fourthly, the sowing date should be adjusted according to the growth characteristics to avoid the high temperature above 28 ℃ during the flowering and filling period. (2) the germination rate and seedling emergence rate of sunflower were lower than those of oil sunflower, and the top soil ability of sunflower was also lower than that of oil sunflower. In order to ensure the number of seedlings, the actual seeding rate should be increased by 10-20% than the calculated seeding rate. The self-regulation ability of sunflower is very strong, the flower disc is small and the grain is small when the planting density is high; The smaller the density, the larger the disk and the larger the grain. Under the premise of ensuring both yield and commodity, 667 square meters of seedlings are protected
