Seven measures to increase the yield of Maize

The main results are as follows: 1. Correctly select improved varieties and hybrids with high yield potential to sow at the right time and plant according to the land.

2. To improve the sowing quality, use the new single-grain on-demand machine and appropriately increase the sowing rate to ensure that the seedlings are uniform, complete and strong.

3. Improve the lighting conditions within the population.

First, reasonable close planting should be carried out according to the characteristics of varieties, soil fertility and cultivation level, and second, strip interplanting and interplanting should be adopted to improve the light conditions in the middle and upper parts of the population.

4. Strengthen fertilizer and water management and adhere to the fertilization principle of "applying sufficient base fertilizer, light seedling fertilizer, skillfully applying stalk fertilizer, attacking ear fertilizer, and applying grain fertilizer", so as to achieve the combined application of nitrogen, phosphorus, potassium, organic and inorganic fertilizers, in order to meet the overall nutrient demand of maize at each growth stage.

5. Timely irrigation and drainage corn trumpet mouth stage and silking stage is the critical period of water demand. In case of drought, the corn should be watered in time to maintain the field capacity of 70% to 80%, so as to promote the differentiation of female and male ears and the formation and development of male ear pollen. At the same time, the flowering and fruiting period of spring corn is in the rainy season, and extreme abnormal weather such as torrential rain is very easy to occur, and stagnant water should be eliminated in time to promote the normal growth of corn.

6. Artificial assisted pollination and interrow emasculated artificial pollination is an effective measure to meet the pollen needs of female panicles and reduce baldness and grain deficiency. Castration can reduce nutrient consumption, promote male and female coordination, reduce borer damage and increase yield, but it is not suitable for continuous rain or high temperature.

7. pay attention to the control of diseases and insect pests in the middle and later stages of corn, we should timely do a good job in the comprehensive control of diseases and insect pests such as large and small spot, sheath blight, corn borer, aphids and so on, so as to ensure the normal growth and development of corn ears.

In corn production, to achieve the above seven points, we can effectively prevent corn empty stalk, baldness, grain deficiency, so as to achieve the goal of high yield.
