Factors Affecting Summer Corn Yield Per Mu and Key Points of Planting Technology
What factors affect summer corn yield per mu? Please provide an introduction and solutions. The main factors affecting summer corn yield are as follows: Reason one, unreasonable corn planting density: excessive planting density is a fairly prominent problem in current summer corn production. For example, some farmers planting "Nongda 108" leave more than 5,000 plants per 667 sq m (1 mu), about 1/3 more than the suitable density for this variety.
What factors affect summer corn yield per mu? Please provide an introduction and solutions.The main factors affecting summer corn yield are as follows:
Reason one, unreasonable corn planting density:
Excessive planting density is a fairly prominent problem in current summer corn production. For example, some farmers planting "Nongda 108" leave more than 5,000 plants per 667 sq m (1 mu), about 1/3 more than the suitable density for this variety.
Because the density is too high, the growth and development of individual plants are poor, the rate of empty stalks is high, the ear tips of the female ears are severely bare, and lodging occurs to varying degrees, resulting in reduced yield.
Reason two, unscientific fertilization of corn:
In corn fertilization, there is a widespread phenomenon of emphasizing nitrogen fertilizer, neglecting phosphate fertilizer, and ignoring potash fertilizer and micronutrient fertilizers, because crop yield is restricted by the law of the minimum nutrient. Applying too much nitrogen fertilizer alone cannot achieve high yield. On the contrary, excessive nitrogen application can lead to poor lodging resistance and serious pests and diseases, causing yield reductions to varying degrees.
In addition, improper fertilization timing and blind application of certain "corn special fertilizers" with too low content of available nutrients (Note: based on the pure content of nitrogen, phosphorus, and potassium; medium and trace elements should not be counted) will both cause yield declines.
Reason three, untimely watering of corn:
Some farmers have a serious mentality of relying on heaven and waiting for rain. They often do not water the "key water" according to the water requirements of corn, but instead only water "life-saving water" under drought conditions, thus seriously affecting yield.
