How to Grow Sweet Corn? The Latest Planting Techniques and Methods Tutorial
Fruit corn is a variety of corn and has a very large market demand in China. Fruit corn can not only be steamed, boiled and eaten in other ways, but can also be eaten raw directly, and it has an extremely sweet taste, making it popular with many people. Nowadays, more and more people want to grow fruit corn, so how should fruit corn be grown? Below, the editor brings you the planting techniques for fruit corn. Let's take a look!
1. Soil selection
Fruit corn cannot self-pollinate, and during the flowering period it also cannot be pollinated with ordinary corn, otherwise its quality will be greatly affected. Therefore, when choosing planting soil, try to avoid having ordinary corn planted nearby. If there is any, keep a distance of at least 300 meters from it and stagger the flowering period with ordinary corn. The soil should have sufficient fertility and strong permeability, then do a good job of land preparation, dig drainage and irrigation ditches, and expose the soil to the sun for ripening. One week before transplanting, apply sufficient base fertilizer, mix it thoroughly with the soil, and then level the soil.

Doing a good job of seed soaking and germination can effectively increase the germination rate of fruit corn seeds. First, we need to soak the seeds in warm water at about 30 degrees for about 5 hours, then take them out and air-dry them. Then wrap them in a wet cloth and place them at a temperature of about 33 degrees for germination. The germination time should be controlled at about 3 days. When more than half of the seeds have sprouted white, they can be sown. When soaking the seeds, be sure to control the germination time well. If the time is too short, the germination effect will be poor and the germination rate will be low. If the time is too long, it will increase the rate of rotten seeds and likewise reduce the germination rate.
3. Sowing and raising seedlings
The germination rate of fruit corn seeds is relatively low, and they are also relatively expensive, so after germination it is best to use seedling pots for raising seedlings. This improves the uniform seedling rate and ensures a full stand. First, apply sufficient base fertilizer in the seedbed. About 7 days before sowing, apply fully decomposed farmyard manure and an appropriate amount of compound fertilizer. Then carefully level and harrow the soil, and sow one seed per nutrient pot. After sowing, cover with about 1 cm of fine soil, then cover with a layer of film to improve heat preservation. After the seedlings emerge, uncover the plastic film, strengthen management, water appropriately, and transplant when the seedlings grow to 3 true leaves.
4. Field management
When transplanting, pay attention to controlling the planting density well to ensure sufficient permeability. When transplanting, apply an appropriate amount of compound fertilizer to each planting hole and then water thoroughly to improve the survival rate of transplanting. After survival, apply an appropriate amount of farmyard manure per mu to meet the nutrients needed for seedling growth. Then do a good job of intertillage and weeding. Field moisture should not be too much, and accumulated water should be drained in time to prevent root rot. When managing the second crop, because the temperature is too high, although the management methods remain unchanged, the time should be appropriately advanced and the amount of fertilizer increased to ensure yield.
The above is a brief introduction to fruit corn planting techniques. The planting techniques for fruit corn are still somewhat different from those for ordinary corn, so everyone should pay more attention to avoid unnecessary losses and affecting planting benefits. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
