Corn Pollination Time and Methods
Here you will find detailed information about corn pollination time and methods, provided by our network. Please read the introduction below.
Corn Pollination Time and Methods
It is best to pollinate corn between 8-10 am when the tassels will open to release pollen. The female flowers should be bagged before the corn silk emerges from the ear, then shake the container near the male corn to drop the pollen into it. After collecting the pollen, screen it to remove the anthers, glumes, and other debris. Once screened, sprinkle the pollen onto the corn silk to complete the artificial pollination.
Corn Pollination Methods
Corn is not self-pollinating but cross-pollinating. Under normal conditions, the male tassels emerge and release pollen first, followed by the female ears, which rapidly complete silk emergence and pollen reception a few days later. After cross-pollination, the silk separates from the ovary wall within 2-3 days. Therefore, when shaking the ear, if a large amount of silk falls off, it indicates successful pollination. If the silk remains tightly attached to the ear, it means pollination has not occurred or was unsuccessful. The characteristic of successful corn pollination is allowing the pollen to fall naturally in the field onto the silk, completing the artificial pollination.Optimal Corn Pollination Time
Cover the open tassels with bags the day before pollination. The female flowers should be bagged before the corn silk emerges from the ear. When the silk is 1-2 cm out, collect the pollen from the male flowers and sprinkle it onto the silk, then close the bags. It is best to pollinate between 8-10 am after the dew has dried.Corn Pollination Methods
Artificial pollination of corn involves manually collecting pollen and applying it to unpollinated silk to increase kernel numbers, especially in dense plantings or poor weather during the pollen release period. How to artificially pollinate corn: collect pollen manually, then apply it. The specific method is to find a container, place it near the male corn, gently shake to drop the pollen into the container, screen the collected pollen to remove anthers, glumes, and other debris, and once screened, sprinkle the pollen onto the corn silk to complete artificial pollination.Declaration: The content "Corn Pollination Time and Methods" is compiled by flower enthusiasts.

Sweet Corn Disease and Pest Control Methods and Techniques
In the early stages of leaf spot disease in sweet corn, you can spray Carbendazim or Thiophanate-methyl. For sheath blight, you can spray Validamycin. It is important to maintain good ventilation in the environment, promptly prune diseased and pest-infested branches and leaves to prevent the spread of pathogens. Corn borers can be controlled with Karate EC, Chlorpyrifos, or Dichlorvos sprays. Early application is recommended. Aphids can be controlled with Pyridaben or Dichlorvos sprays.
Common Diseases in Sweet Corn Cultivation
1. Northern Corn Leaf Blight: Also known as stripe disease, sooty stripe disease, blight, and leaf spot disease, it damages leaf growth and occurs in various regions of our country, causing significant harm.
2. Southern Corn Leaf Blight: It can occur from seedling stage to maturity, damaging leaf growth. Sometimes the stem and ear are also affected. The lesions are small and numerous, initially appearing as water-soaked spots that expand into oval lesions with red halos. In some cases, ear rot and black seeds may occur.
3. Corn Rust: Corn rust mainly damages leaves, particularly the upper and middle parts. The lesions appear as faint yellow spots on the leaf surface, which gradually become raised and expand. In later stages, circular black protrusions grow on the lesions.
Major Insect Pests in Sweet Corn Cultivation
1. Corn Borer: It can damage the growth of the above-ground parts of corn. The female moth lays eggs on the back of corn leaves, initiating damage. It can also be carried by wind to neighboring plants, causing cross-infection.
2. Armyworm: Armyworm is a polyphagous, migratory, and outbreak-prone pest. Its occurrence is closely related to temperature and humidity. Higher air humidity favors egg laying by the adult moth. Under alternating cloudy and sunny, high-temperature, and rainy conditions, not only is egg laying favored, but it also benefits the development of larvae.
3. Corn Aphid: It mainly sucks the sap from corn, hindering growth and transmitting various viruses. Its secretions can adhere to pollen, affecting pollination. Moreover, it can transmit viral diseases, leading to varying degrees of yield loss.
Disease and Pest Control in Sweet Corn
1. Diseases: In the early stages of leaf spot disease, you can spray Carbendazim, Thiophanate-methyl, or Mancozeb. For sheath blight, you can spray Validamycin. It is important to maintain good ventilation in the environment, promptly prune diseased and pest-infested branches and leaves to prevent the spread of pathogens.
2. Pests: Corn borers can be controlled with Chlorfluazuron suspension concentrate or high-efficiency BT wettable powder sprays, or by mixing Carbaryl wettable powder with fine soil to create poisoned soil. Alternatively, you can use Karate EC, Chlorpyrifos, or Dichlorvos for ear irrigation or spraying. Attention should be paid to the dosage and application time of the pesticides, with early application recommended. Aphids can be controlled with Pyridaben or Dichlorvos sprays.
Growing Environment and Conditions for Corn
Corn prefers a warm growing environment, requiring high temperatures and sufficient sunlight. However, it is important to avoid excessive sunlight exposure, as it can hinder growth. Corn is commonly found in northeastern and northern China, requiring temperatures between 10-35 degrees Celsius for growth.

Corn prefers a warm growing environment, requiring high temperatures and sufficient sunlight. However, it is important to avoid excessive sunlight exposure, as it can hinder growth. Corn is commonly found in northeastern and northern China.
Corn Growing ConditionsCorn requires high temperatures for growth. When planting, it is best to use loose and fertile soil, and watering should be moderate to avoid waterlogging.
Corn Growing TemperatureCorn requires temperatures between 10-35 degrees Celsius for growth. The temperature should be maintained around 15 degrees Celsius during germination to avoid hindering growth.
Growing Process of Corn
Corn requires a suitable temperature environment for growth. After planting, it will germinate in about a week and require sunlight. After about two months, it will develop silk and produce male pollen. After flowering, it will begin to fruit, requiring sufficient water.
Suitable Soil for Corn Cultivation
Corn has no strict requirements for soil conditions and can be grown in various types of soil. However, deep, well-structured, fertile, nutrient-rich, loose, well-drained, and neutral soil with coordinated water, fertilizer, air, and heat is the most suitable for cultivation. Sandy loam, black calcium soil, and chestnut soil with rich organic matter are preferred.
Requirements for Corn Cultivation Soil
Corn is a warm-season crop that requires sufficient temperature for germination and fruiting. It has no strict requirements for soil conditions and can be grown in various types of soil. However, deep, well-structured, fertile, nutrient-rich, loose, well-drained, and neutral soil with coordinated water, fertilizer, air, and heat is the most suitable for cultivation.
Generally, corn is best suited for cultivation in loose, deep, and rich organic matter soil such as black calcium soil, chestnut soil, and sandy loam.
Soil for Corn Cultivation
Corn has a wide adaptability to soil and requires fertile soil with good drainage and aeration. It can also be combined with some organic soil or organic fertilizer.
1. Sandy Soil
Heavy clay soil has poor drainage and aeration, leading to soil compaction and slow growth. Sandy soil, on the other hand, is loose and well-drained, resulting in high seedling emergence and rapid seedling growth. However, it has poor water and fertilizer retention, affecting growth in later stages.
2. Organic Soil
High-yielding corn requires a large amount of nutrients. Therefore, it is best to choose soil rich in nutrients for its growth.
Preparation of Nutrient Soil for Corn
You can mix 2 parts coarse sand, 2 parts loam, 1 part perlite, and 1 part red ochre powder and mix thoroughly; or you can prepare some river sand and ordinary garden soil, mixing them in a 2:1 or 3:1 ratio. This soil has high permeability and is suitable for corn growth.
