How to grow fruit corn? Corn can be eaten raw, but some varieties are very sweet and delicious, such as fruit corn, juice is more crisp and sweet is its characteristics. Someone asked if fruit corn can be cooked and eaten? Of course, fruit corn is actually a lot of practice, but the main thing to be aware of is the technical point of fruit corn cultivation.
First, isolation cultivation
Fruit corn is genetically controlled by homozygous recessive genes and cannot be smashed with other common corns, otherwise it will lose its unique flavor. It can be separated from other types of corn by more than 300 meters in the cultivation, or it can be staggered for more than 30 days. It can also be isolated by barriers such as houses.
Second, staged sowing
The fruit corn harvesting period is short, and the staged sowing can realize batch picking and listing. Generally, the temperature of 5 cm is transmitted through spring at 12 °C, and the summer is broadcast in mid-July. In the appropriate sowing period, the earlier the sowing, the higher the yield. The cultivation with the mulch cultivation can be sown 5 to 7 days in advance. Avoid sowing in late May to mid-June. This period of corn flowering pollination period is in the drought from July to August, which is easy to cause baldness, lack of grain and empty stalks.
Third, soil preparation and fertilization
Fruit corn has a short growth period. Before ploughing, 667 square meters of fertilized organic fertilizer 2000 kg, compound fertilizer 15 kg, potassium fertilizer 5 kg, deep turn and soil fully mixed. When the spring is combined, the ground is cut, and the land is finely grounded.
Fourth, the seedlings are planted
Fruit corn seed wrinkles, small endosperm, weak top soil, low germination rate, should be sown for 2 to 3 days before sowing, suitable for shallow sowing. The depth of the sowing is 2 to 3 cm, and the soil should not be too deep.
V. Planting density
The density of fruit corn planting should not be too large, and it should be properly planted to facilitate the fullness of the ears, not bald, no grain, and good shape. Generally it is 3500~4000 plants/667 square meters.
6. Field management
1. Check the seedlings in time to eliminate the weeds after emergence.
2.4 leaf stage and time to set seedlings, to weak seedlings, diseased seedlings, stay strong and strong seedlings.
3. In the seedling stage and the mid-growth period, the tillers and excess small ears are removed in time, and one ear in the upper part of the plant is kept to concentrate the nutrients and the ear is fully developed.
4. The fruit corn leaves are flat and the plant type is loose. The base fertilizer should be applied, the seedling fertilizer should be applied early, and the panicle fertilizer should be applied. In the case of sufficient base fertilizer, the “pre-light and heavy†topdressing method is adopted, that is, the light fertilizer is applied and the panicle fertilizer is applied again, and the ratio of the two is 4:6. The field where the base fertilizer is insufficient is the opposite.
5. The head water is properly irrigated late to facilitate the seedlings, promote the root system, and irrigate 4 to 5 times during the whole growth period. Guarantee the water supply of jointing, big bell mouth, tasseling and grouting.
Seven, pest control
Fruit corn seedlings grow weak, and are susceptible to pests in the later stage. It is forbidden to use chemical pesticides, adhere to agricultural control, physical control, biological control, and use biological insecticides to control pests such as corn borer, corn leafhopper, spider mites, and white star flower.
Eight, timely harvest
The harvest time of fruit corn is very important. The harvest has too little grain content, low sugar content and poor flavor. When it is too late, the water is small, the grain is aging, the skin is thick and thick, the mouthfeel is poor, and the commodity value is low. The picking period is about 3 days earlier than the average sweet corn. Generally, it is harvested or processed according to the color of the filament and the field in the field about 20 days after pollination. The raw food must be sold now and sold to ensure the taste.
Nine, benefit analysis
According to the harvested ear 3500 ~ 4000 / 667 square meters, the unit price of 0.5 yuan / piece, the output value of 1750 ~ 2000 yuan / month, the cost of 400 yuan, 667 square meters of net income of 1350 ~ 1600 yuan. Fruit corn stalks are rich in nutrients, fresh and palatable, and are high-quality feed for animal husbandry.
The above is the main point of high-yield planting techniques for fruit and corn. The favorite growers can collect and learn. If you have your own set of planting techniques for fruit corn, welcome to share!
Biological fingerprint safe have the characteristics of uniqueness and stability, without the permission of the highest authority of the manager, any individual without qualified fingerprints can not enter. Therefore, the fingerprint safe relative to other categories of safe, a good solution to the problem of others imitation keys to open the door. If you use a traditional mechanical safe, you may face risks such as having a key made by others or using a special unlocking tool to open the lock.
Traditional Safe Box often require keys or combinations to open, which can be easily lost or forgotten. With a tiger fingerprint safe, you simply need to place your finger on the scanner to open it. This eliminates the need to remember or carry keys or codes, making it more convenient and efficient.
Many tiger fingerprint safes have the ability to store multiple fingerprints in their system. This means that you can grant access to multiple individuals, such as family members or trusted employees, without the need to share keys or combinations. Each person can have their own unique fingerprint registered, ensuring accountability and security.
