Is fruit corn genetically modified? Is the planting benefit good? What cultivation techniques do you need to master?

Fruit corn is a kind of super sweet corn suitable for eating raw. Its thin skin breaks as soon as it bites, and its fragrant juice overflows its teeth and cheeks. It is especially sweet and crisp when eaten raw and cooked, like fruit, so it is called "fruit corn". Is fruit corn genetically modified? Is the planting benefit good? What cultivation techniques do you need to master?

Is fruit corn genetically modified?

Fruit corn is not genetically modified food. It is a kind of natural sweet corn, which is called fruit corn because it tastes sweet and crisp. Sweet corn existed as early as 1779.

The so-called concept of transgenic is to add the genes of one species to another. This phenomenon already exists in nature, but human beings rely on this technology to make changes.

The introduction of insect resistance and herbicide resistance through transgenic technology can improve the adaptability of fruit maize in the field, so as to increase the yield of maize, reduce the harm to the environment due to pesticide spraying, and reduce the labor intensity of farmers' field management. In this way, the cultivated fruit corn becomes "genetically modified corn", although its sweet traits have nothing to do with transgenic technology.'

Second, is the planting benefit of fruit corn good?

The growing period of fruit corn is short, and the growing period of fruit corn is only 70-85 days from sowing to maturity, which is the same as ordinary corn in management, but reduces the labor such as threshing and drying in the later stage.

Delicious, beauty and health care fresh fruit corn is rich in linoleic acid, which has a good preventive effect on hyperlipidemia, hypertension and diabetes; it is rich in vitamin E and has a good cosmetic effect; it is rich in cellulose and improves digestive function. Glutamic acid has a good health effect on the brain; glutathione is recognized as an anticancer substance and can prevent the production of cancer cells to a certain extent.

The planting efficiency is high, and the yield of open-market fruit corn is similar to that of ordinary corn, but the price is 2 to 3 times higher than that of ordinary corn. Autumn cabbage, radish and scallions can be planted in the next crop of fruit and corn, and the income can be increased by more than several hundred yuan per mu. The green corn stalk after harvest is also the best raw material for cattle and sheep feed.

3. Cultivation techniques of fruit corn

1. Soaking seeds to accelerate germination

Fruit corn seeds are more expensive, soaking seeds to accelerate germination can increase germination rate, save seeds and reduce agricultural cost. The method of soaking seeds to promote germination: soak the seeds in 25-28 ℃ warm water for 4-5 hours, pick them up and drain, wrap them with wet towels, place them in the incubator of 32-34 ℃, accelerate germination for 30-36 hours, and sow seeds after the seeds are exposed to white.

2. Cultivate strong seedlings

The seed of fruit corn is withered, and the emergence rate of direct seeding is very low, which is not only a waste of seeds, but also not conducive to full seedling, whole seedling and uniform seedling, which has an impact on future management, harvest and yield. Therefore, the cultivation of fruit corn must be raised in a nutrition bowl. The nursery bed should be fully fertilized with a load of human and animal manure per 3-meter-long seedbed one week before sowing, 500 grams of high-efficiency compound fertilizer and ammonium bicarbonate, and should be fully tipped and refined after fertilization.

3. Daejeon site selection and preparation

Fruit corn is a cross-pollinated crop, the florescence can not meet with conventional waxy corn or feed corn, otherwise flour can affect the quality. Distance interval and childbearing interval are generally used.

4. Transplanting specifications and quality

Fruit corn is planted in wide and narrow rows in the field, with a wide row of 1.2-1.4m, a narrow row of 0.5m-0.6m, a plant spacing of 30-35cm, and about 2800 plants per mu, which is too dense and is prone to bald grains.

5. Scientific management

10 kg of ammonium bicarbonate plus 20 kilograms of human and animal manure per mu was used as seedling fertilizer, 10 kg of urea or 20 kg of ammonium bicarbonate was applied as jointing fertilizer per mu before jointing, and 20 kg of high efficiency compound fertilizer + 10 kg urea was applied as spike and grain fertilizer before male flower extraction.
