· How to grow sweet corn? Sweet corn planting technology?

Sweet corn is rich in nutrition, sweet, fresh, crisp, tender, etc., and is favored by consumers of all classes. It is a type different from other corn. Many varieties of sweet corn are found. 


Planting time of sweet corn


Sweet corn can be divided into spring corn and autumn corn, and their planting time is also different. Spring corn is down around the end of April each year, and it can be mature and marketed in mid-to-late August, while autumn corn is. They are sown after closing in mid-July each year, and their maturity time is around mid-to-late October each year. If conditions permit, sweet corn can also be grown in greenhouses in winter.


How to grow sweet corn:


Sweet corn is a type of corn. Because it is relatively sweet, it is mostly presented in western salads. Next, the editor will give you a detailed introduction to the cultivation methods of sweet corn.


It takes about 85 days from the emergence of seedlings to the harvest of fresh ears.


1. Planting method of sweet corn, site selection, soil preparation and fertilization.


· What experience do you have in high-yield cultivation of sweet corn?

Sweet corn has become more popular in recent years and has been planted more frequently. Today, I will share with you what are the experiences of high-yield cultivation of sweet corn?


Those experiences in high-yield cultivation of sweet corn:


Planting in isolation. In order to prevent hybridization with other corn varieties, reduce sweetness and affect quality, sweet corn must be planted in isolation. The isolation area is required to be more than 400 meters, and time difference isolation can also be adopted, and the flowering period is required to differ by more than one month.


Fine seedlings. The seeds of sweet corn are shriveled, the ability to germinate and top soil is poor, the germination rate is low, the growth of seedlings is weak, and the soil requirements are high. Generally, deep turning, rake leveling, and fine crushing are required to make the soil loose and have good moisture content, and to create a suitable soil environment for seed germination and seedling growth. Seeds must be carefully selected to remove insect seeds, bad seeds, and mold seeds. When planting, the soil moisture should be suitable, and the planting should not be too deep, and the soil should be about five centimeters. At the same time, ensure that the depth of the soil is the same, and strive for all seedlings. Apply plantar fertilizer between holes and dilute 5-10 kg of liquid seed dressing with new high-lipid film mother liquor to repel underground pests and isolate virus infection.


Field management. Under the condition of general soil fertility level, phosphorus and potassium fertilizer are applied as base fertilizer at one time. Water management should pay attention to preventing waterlogging in the seedling stage and preventing drought in the middle and late stages. Due to the slow growth of sweet corn seedlings, the seedling period is prone to weeds, so they must be cultivated as soon as possible to eliminate weeds. Prevent corn borer in time from joining to a big bell mouth, use low-toxic pesticides, and use new high-lipid film when spraying, which can reduce pesticide toxins and increase efficacy. Cultivating soil and pressing roots promotes growth, increases yield, and improves sweetness.


· Summary of high-yield technology of northern sweet corn


In recent years, people prefer to eat sweet corn. It has rich nutritional value and is a new food that is particularly nutritious for both fruits and vegetables. Because of its rich nutrition, unique flavor, short growth period, simple cultivation techniques, and high economic value, it has become one of the "three highs" agricultural crops and has a good market prospect. Through practice in recent years, related experiments and demonstrations have been carried out in accordance with the idea of ​​"high-yield and high-quality", and the key technology of sweet corn cultivation has been summarized, which provides a reference for high-yield cultivation of sweet corn.


1. Types of sweet corn


1. Ordinary sweet corn


The sugar content of ordinary sweet corn kernels reaches about 10%, which is twice as high as that of ordinary corn. Ordinary sweet corn grains can accumulate a large amount of water-soluble polysaccharides, which have a relatively small molecular weight, are water-soluble and waxy, and are easily absorbed by the human body. The starch content is only about 35%, which is half that of ordinary corn.


· High-quality and high-yield cultivation techniques for sweet corn

Sweet corn contains very rich nutritional value and is a nutritious food for both fruits and vegetables. Sweet corn is bright and shiny in color, fragrant, sweet, crisp, and can be eaten raw or cooked. Today I will tell you the key techniques of sweet corn cultivation for your reference.


The first is that when we select varieties, we should choose varieties with strong applicability, disease resistance, high yield and high commercial value, and the second is fine soil preparation. Because sweet corn seeds generally have relatively deflated and small grains, they should germinate and emerge from the soil. Ordinary corn seeds are difficult, so it is necessary to cultivate seedlings carefully. When planting sweet corn, there are two points for sowing, one is staged sowing and the other is fine sowing. The field management of sweet corn also accounts for the main part. Thinning, setting seedlings, drought-resistant watering, and prevention and control of diseases and insect pests are all indispensable items. Then, after these attentions are over, harvesting should be done in a timely manner. The sweet corn harvest time is generally 22-28 days after spinning. If it is harvested too early or too late, the harvested sweet corn will not have good taste or nutrition. So everyone must grasp this time. That's all about the cultivation technology of sweet corn today, I hope it will be helpful to everyone.


· Be cautious when using fertilizer for sweet corn


It is understood that sweet corn should be planted in loam with sufficient sunlight, water and fertilizer, and fertile soil, which is more conducive to the growth and development of sweet corn.


According to relevant reports, sweet corn is also called vegetable corn. Sweet corn is composed of endosperm and immature caryopsis. Sweet corn is widely planted because of its high sugar content and long suitable harvest period. Sweet corn should be sown with high-quality, disease-resistant varieties. As the seeds of sweet corn are relatively deflated, germinated, and arched in the soil, agricultural personnel should carefully cultivate seedlings. When planting, the soil should be deep plowed and refurbished, and the soil should be loosened, drained and irrigated. Convenient plots for sowing. After the corn crops are harvested, plow and turn 20 cm-30 cm in time, combined with plowing and apply sufficient sweet corn base fertilizer. Generally, sweet corn is applied with 667 square meters of organic fertilizer 1000-1500 kg and superphosphate 30-40 kg per mu. 20 kg of potassium sulfate, 1-1.5 kg of zinc sulfate or 20 kg of special fertilizer for corn are used as base fertilizer. When planting sweet corn, agricultural personnel should carry out reasonable dense planting to determine the appropriate planting density of sweet corn. Under the general medium fertility soil, it is advisable to sow 4000 plants per 667 square meters.


In order to effectively improve the yield of sweet corn, fertilizer and water management should be strengthened. Fertilization of sweet corn is very important. After the emergence of sweet corn, agricultural personnel should check the seedlings and replenish them in time. When the seedlings are 3-4 leaves, the seedlings should be fixed. The seedlings should ensure that the sweet corn is uniform and consistent. The sweet corn is cultivated and weeded, and the ear-attack fertilizer is applied to ensure the growth and development of the sweet corn plants. Generally, 30kg of urea is topdressed per 667 square meters, and 15kg is top dressed in sweet corn jointing stage and bell mouth stage. Each time sweet corn topdressing should be applied as deep as possible, and each application should be combined with loose soil. During the growth period of sweet corn, sufficient water needs to be added, which is a critical period for sweet corn to be irrigated. When the soil surface is dry, water should be timely to prevent the lack of seeds at the top of sweet corn ears and promote the growth of sweet corn.






The above is the relevant knowledge about the prevention of growing technology and control of sweet corn pests and diseases summarized in the next post  and I hope to help you.
