I. How many cobs does a corn plant grow

Generally, corn can only produce one or two ears, but certain resources can produce many. Corn generally has 13 - 26 (inaccurate) leaves, and some can bear more than eight ears. Also, if the growing point is destroyed during the pulling stage, several new branches will be sent out, and theoretically the same corn plant, and it's not really certain how many ears it can bear under good fertilizer and water conditions.

There is another situation, some corn seedlings will be like wheat like tillering, will also appear more branches and more ears.

Remove the above situation, commercial corn knot more than three ears, it is not normal.

Two, corn yield new technology

1, timely watering

Corn in the tasseling period this stage is the whole growth period of the most water-consuming stage, accounting for the entire growing period of thirty-five percent. Tasseling period is the critical period of corn in the change of water demand. If the amount of water needed to meet the corn's needs during the tasseling stage is not met, drought and water shortages can lead to significant yield reductions and, in severe cases, even crop failure. The final yield of corn has a great impact, the soil is too dry to timely watering, to avoid the phenomenon of yield reduction due to lack of water.

2, timely fertilization

The corn tasseling period is not only the largest water demand, but also the entire growth period of the largest and strongest fertilizer requirements. But also according to the growth of corn proper fertilization, for example, those corn kernels full, fat corn is generally in is in the spitting time to apply the appropriate nitrogen fertilizer. Because the quality has reached the goal, so the nitrogen fertilizer is applied to promote the fruiting rate of corn and increase the weight of corn kernels for the purpose.

3, medium tillage cultivation

The purpose of medium tillage is to strengthen the soil ventilation and air permeability, and at the same time to cope with the supply of fertilizer and water status and remove weeds in the garden, to promote the growth and development of corn roots. Cultivation is to increase the aerial roots of corn, mid-tillage cultivation can improve the corn's resistance to collapse, because in the fall windy season, corn collapse is very common. So after fertilizing the corn, cultivate the soil as soon as possible to strengthen the corn's resistance to fall.

4, late harvest

Corn can be late harvest, do not have to harvest immediately at maturity, because the late harvest can ensure that the corn is enough to give the corn kernel grouting time. Corn grouting is a measure to increase the weight of corn kernels, increase yield and improve quality. Harvesting corn at the stage of full maturity around the beginning of autumn, when the bracts of corn are found to turn white and dry up, etc. is a sign that the corn kernels have fully matured, and it is the period when the weight of corn kernels is at its highest. Experiments have proved that every three days to delay harvesting, thousand grain weight increased by about ten grams. And does not require any cost.
