It depends on the variety, grain thickness, corn cob size, single grain weight, sparse planting, fertile land, black soil and yellow land, saline-alkali land, salt-free land and so on. There are many reasons for this. It is impossible to talk to a piece of land. The same variety, the same fertilizer, is different in different fields.
Extended data:
Main influencing factors
1, varieties, different varieties, this number will be different, some varieties of corn cob is bigger, the weight will be heavier, the weight of corn kernels will be reduced, on the contrary, some varieties of corn cob is thinner, so the weight of corn kernels will be heavier.
2. It is also related to the planting density. If it is a reasonably densely planted plot, other conditions being the same, ventilation and light transmission will be better, corn kernels will be fuller, and the weight of corn kernels will be heavier if the corresponding kilogram of corn is hit with a stick. On the contrary, if it is a densely planted plot, the corn kernels are not necessarily good.
On the one hand, the seeds are not full, on the other hand, there may be bumps. In this case, a catty of corn with a stick will be lighter.
3. From the perspective of planting management technology, if the field management from seedling stage to harvest stage is very good, corn will grow normally and there will be no baldness and lack of grain. At the same time, the grain is full, the corn grain weight is relatively large, and the final total output will be higher.
On the contrary, the management of weeding, pest control, watering and fertilization in the field has not been done well, and the final result can be imagined that both the content and the total weight of a catty of corn kernels will be reduced.
