Fruit corn can be planted in the north. Its cultivation techniques are as follows: fruit corn is suitable for eating a kind of sweet corn, compared with the general sweet corn, its main features are thin skin, juicy, crisp and sweet, can be eaten directly raw, can also be cooked and eaten. Fruit corn and sweet corn are not essentially different, the general sweet corn can be eaten raw, just the taste of the difference between good and bad, good taste is people as fruit corn, so there is no special fruit corn varieties in cultivation. Fruit corn cultivation techniques are similar to sweet corn, generally to grasp the following points: staged sowing: in order to prevent cascading flowers to reduce the quality, fruit corn should be planted in isolation from other types of corn. It can be isolated in planting spacing (more than 300 meters) and flowering period (more than 30 days), or it can be isolated by using barriers such as hillocks, forests and houses. Fruit corn picking period is short, freshness is difficult, staged sowing can be realized in batches picked on the market, generally at the end of March to the beginning of August can be sown, early spring with thermal insulation facilities can also be appropriate in advance, but should be avoided in late May to the middle of June between sowing, sowing in this period of corn flowering and pollination period is encountered in July-August drought weather, easy to cause the plant bald tip, lack of grains or empty stalks. Germination sowing: it is advisable to choose a higher level of soil fertility, sufficient fertilizer and water in the sandy loam soil cultivation of fruit corn, before sowing to fine ground preparation. Fruit corn seed wrinkled, endosperm small, germination rate is low, weak seedlings, in order to strive for seedling Qi, seedling full, seedling strong, whether it is direct seeding or seedling transplanting, it is best to implement the germination seeding. Scientific fertilization: fruit corn leaf spreading, loose, planting density of 3500-4000 plants per mu is appropriate. Fertilizer should be appropriate to apply base fertilizer, early application of seedling fertilizer, heavy application of spike fertilizer, nitrogen, phosphorus and potassium with the application, promote the application of organic fertilizer. Medium fertility of the total amount of fertilizer control in the field of pure nitrogen 15 kg, phosphorus (phosphorus pentoxide) 6 kg, potassium (potassium oxide) 6 kg or so. Fine management: fruit corn seedling growth is weak, late susceptible to pests, so we must do a good job of field management in a timely manner. Seedling to timely check the seedling to make up for the shortage, weed prevention, seedling and mid-term to break off tillers and excess small ears, mid and late to control the corn borer and other pests. The picking period of fruit corn is about 3 days earlier than the general sweet corn, about 20 days after pollination, according to the color of the filaments and field tasting, in time to grasp the best picking period.
