Multi-broadcasting method is adopted, trenches are set in the furrow at a row spacing of 20-30 cm, and the furrow depth is 1.5-2 cm(104 cell seed starting trays). The seeds are mixed with fine sand and evenly spread into the furrow. Therefore, five meters has an important interest in agricultural production and grain composition(4 gallon plant pot).

The content of unsaturated fatty acids in corn oil is as high as 60%, and the nutritional value is very high(plastic flower pots bulk). Growing up to eating corn oil has a good effect on preventing high blood pressure, reasonable irrigation and fertilization techniques.

In the 1970s, the annual planting area of corn in China accounted for 12-16% of the area of grain crops(mushroom growing trays), and the total output accounted for 18-20% of grain crops.
