Agronomic requirements for sowing:
Sowing in time: the soil or seedbed is smooth and soft, and the moisture content is appropriate.
Sowing rate: the sowing rate per mu is generally 3-5kg,3000-5500 basic seedlings per mu, actual sowing amount is determined by the characteristics of local varieties.
Row spacing of sowing: equidistance row is generally between 50-70cm.
Planting spacing: required to be 60-70cm.
Depth of sowing: generally required to be 5-6cm,the deepest depth is less than10cm.
Agronomic requirements for fertilizing:
Regular fertilization: The deep application of seed fertilization is 5-8cm under the seed and about 5cm by the seed side.
Techniques of sowing and fertilizing:
The mechanized technology of corn sowing is adopted to complete the operations of deep fertilizer, sowing, covering soil, ridging and pressing at one time.

Harvesting
Recommended products
Transporting mode:
Corn mechanical harvester is a combination of corn mechanization technology , which can be used to harvest , transport, stack, and straw-post treatment and other operations.
The self-propelled corn combine harvester has the advantages of compact structure , perfect performance, high operation efficiency and good operation quality , which is representative in the development trend. At present , the technology of this type of products is gradually developed and mature , which has a wide range of promotion and application.
Agronomic requirements:
Grain loss rate≤2%,kernel loss rate≤3%,grain break rate≤1%,stubble height≤8cm,
moisture content below 20% when corn threshing,straw chopping length≤5cm,
straw throwing uneven rate≤20%.
