The latest High-yield Field Management of Maize

Corn is one of the most common food crops in China, and it has been planted widely in China. This stage is the time when the corn leaves are the largest and most, and it is also the best period to determine the weight of corn kernels. The growth and development of this stage determines the final yield and quality. Therefore, in order to achieve high yield, field management at this stage must be strengthened.

1. Timely watering

The heading stage of corn is the most water consuming stage of the whole growing period, accounting for 35% of the whole growing period. Tasseling stage is the critical period for maize to change its water requirement. If there is not enough water to meet the needs of corn at heading stage, drought and water shortage will lead to a significant reduction in corn production, even a serious failure. It has a great impact on the final yield of corn. If the soil is too dry, water it in time to avoid the phenomenon of yield reduction caused by water shortage.

2. Timely topdressing

The heading stage of maize is not only the period of maximum water requirement, but also the period of maximum fertilizer requirement during the whole growth period. However, appropriate fertilization should also be applied according to the growth of corn. For example, those corn grains that are full and fat are generally applied with appropriate nitrogen fertilizer at the time of silking. Since the quality target has been achieved, nitrogen application is intended to promote seed setting and increase kernel weight.

3. Cultivation

The purpose of cultivation is to improve soil ventilation and permeability, to cope with fertilizer supply and weed removal, and to promote the growth and development of corn roots. Cultivation is to increase the aerial roots of corn, intertillage can improve the lodging resistance of corn, because in the autumn windy season, corn lodging is very common. Therefore, after topdressing corn, as soon as possible, cultivate soil, strengthen corn lodging resistance.

4. Late harvest in due course

Corn can be harvested late in time, not immediately at maturity, because late harvesting ensures that corn has enough time for grain filling. Corn grain filling is a measure to increase the weight of corn kernel, increase yield and improve quality. Harvest corn at the stage of full maturity around the beginning of autumn. When the bracts of corn turn white and dry, it represents that the corn kernel is fully mature and the weight of corn kernel is the highest. Experiments have shown that every three days delayed harvest, 1000-grain weight increased by about ten grams. And it doesn't cost anything.

The tasseling period of corn is the most important period of corn. The field management of corn at the tasseling period is the prerequisite to ensure the high yield of corn, and the fertilizer and water required by corn at this stage should be ensured. Of course, we must also prevent and control diseases and insect pests. General diseases and insect pests include stem rot, aphids, etc. Good pest control, corn high yield will be more guaranteed.
