1, rational close planting. According to the physiological characteristics of the varieties, a reasonable planting density is adopted so that the corn groups have good ventilation and light transmission conditions, so that the individual corn can get a good development and the occurrence of corn baldness can be reduced.
2, re-appropriate attacking panicle fertilizer. Corn dressing should be based on the principle of light weight, medium weight and full complement. When corn grows to about 15 leaves, 10 kg of urea or 10 to 15 kg of ammonium nitrate can be applied with watering. From corn heading to grain filling stage, 0.25 kg of potassium dihydrogen phosphate and 0.5 kg of urea are used for 40-50 kg of water per acre and sprayed on the leaves in the afternoon for extra-root fertilization, which can significantly reduce bald head.
3, to male. After detasseling, the consumption of water and nutrients was reduced, causing the ear to grow thick and full. At the same time, the upper air and light transmission conditions of corn were improved, photosynthetic efficiency was improved, and the damage of corn borer was reduced. The time of detasseling should be appropriate when tassels have just been removed from the parietal lobe. The number of detassels can be emasculated by an interlace or septum. Not too much, otherwise it will cause poor pollination, resulting in empty ears, especially in the 4 to 5 lines around the corn field should not be emasculated.
4. Artificially assisted pollination. Artificial pollination should be carried out during the period of Taro Powder, usually 2 to 3 times. The time should be around 10 a.m. The method is two people pulling a rope, walking along the lines, so that the rope moves the tassels swinging, or pollen pollen is attached to the ear of the flower on the head, gently shaking, so that the pollen grains evenly fall on the filaments.
5, cut short filaments. After the female silk of maize has exposed the loquat leaves, the pollen is pollinated on the falling silk. After the female flowers are pollinated, the filaments are shriveled. But often due to uneven filaments, the upper part of the late drawing, some filaments continue to grow without pollen, until 10 to 15 cm long. As the filaments are too long, they cover each other and affect the pollination of the underlying filaments. Therefore, the filaments should be cut short, leaving only 1.5 to 2 cm, making the filaments like bread-like or horseshoe-shaped, short and long before the former, favorable pollination, can reduce baldness.
With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.
The content of sarcosine in beef is higher than any other food, and it is particularly effective for growing muscle and strengthening strength. In the first few seconds of training, sarcosine is the source of muscle fuel, effectively supplementing adenosine triphosphate, allowing training to last longer.
