What are the cultivation techniques of fresh waxy corn? What are the precautions when planting?

Glutinous corn, commonly known as sticky corn, is rich in nutrients such as lysine and vitamins necessary for human body, and contains calcium, phosphorus, iron, selenium and other elements. Moreover, waxy corn cultivation cycle is short, economic benefits are high, and it is favored by farmers and processing enterprises. So what is the cultivation technology of fresh glutinous corn? What are the precautions when planting?

1. What are the cultivation techniques of waxy corn?

1. Isolated planting

Waxy corn belongs to recessive gene control. If it is "flying flower" of other types of corn, it will become non-waxy. The following methods can be adopted for isolation planting:

(1) Spatial isolation: a distance of more than 350 meters.

(2) Barrier isolation: use obstacles such as mountains, forests and houses.

(3) Time isolation: Spring sowing is 30 days apart.

2. Seeding at the right time

Generally, waxy corn is sown in the middle and late November, 2 rows per ridge, row spacing 25--30cm, 2--3 seeds per hole, 3500--4000 waxy corn plants per mu. Pay attention to the film edge pressure should not be too much, in order to maximize the maintenance of film surface width, expand lighting surface, improve the utilization rate of plastic film.

3. Field management

Timely drainage irrigation, reasonable topdressing. According to waxy corn growth conditions, soil moisture, timely irrigation. Water in time in case of drought and drain in time in case of waterlogging. At jointing stage and big bellmouth stage, top dressing is carried out in combination with irrigation, furrows or holes are dug at the place 10cm away from waxy corn plants, and urea is applied 16- 18kg per mu. To meet the zinc requirement of maize, zinc sulfate 100- 150 g mixed with water 50kg was sprayed on leaves 1- 2 times to prevent white mosaic disease.

II. What are the precautions for planting fresh glutinous corn?

1. Select good seeds

It is better to select hybrid varieties suitable for local natural conditions and cultivation conditions, plant varieties according to market needs, pay attention to the planting of early, medium and late maturing varieties, prolong the supply time on the market, and meet the needs of the market and processing plants.

2. Planting in isolation from ordinary waxy corn

When waxy corn crosses with common corn, it will cause the waxy corn seeds to lose their waxy nature and reduce their commercial value. Therefore, waxy corn planting must be isolated from other corn planting, generally should maintain a distance of more than 200 meters. The other is to sow in stages with other corn, and the flowering period of corn should be separated by more than 15 days.

3, need reasonable density planting

Early-maturing waxy corn plant especially short, should be about 4000 plants per mu, middle-maturing varieties should be about 3500 plants, late-maturing varieties should be about 3200 plants.

4. Pay attention to increasing the application of organic fertilizer

Waxy corn fertilization technology should pay attention to increase organic fertilizer, balanced application of nitrogen, phosphorus and potassium fertilizer, topdressing should be based on available nitrogen and potassium topdressing.

5. Harvest time should be grasped

The harvest time of spring sowing waxy corn was 26~28 days after pollination, and that of autumn sowing waxy corn was 35 days after pollination. Harvesting too early or too late is not conducive to the best commercial value of waxy corn. Harvesting too early, the kernel is not strong, the taste is not good, and harvesting too late lacks fresh sweet taste.
