Rice high-yield fertilization should be adapted to the field

Reasonable formula fertilization improves the utilization rate of fertilizer, reduces the amount of chemical fertilizer application, protects the farmland ecological environment, maintains the ecological balance, and increases the income of farmers. It plays an extremely important role. Different fertilization methods should be used for fields with different fertility:

First, the ingenious formula

1. High fertility field

The target output is more than 650 kg/mu, and 1000-1200 kg of organic fertilizer per mu is used as the base fertilizer. The recommended formula for single-fertilizer is: 11~13 kg of urea, 15~20 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5), and apply 35~40 kg per mu.

2. Zhongfei Litian

The target output is 600 kg/mu, and the organic fertilizer is applied with 1200~1500 kg per mu as the base fertilizer. The recommended formula for single chemical fertilizer is: 13~15 kg of urea, 20~25 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5) and apply 40~50 kg per mu.

3. Low fertility field

The target output is 550 kg/mu, and 1500~2000 kg of organic fertilizer per mu is used as the base fertilizer. The recommended formula for single chemical fertilizer is: 15~17 kg of urea, 25~30 kg of calcium, and 8 kg of potassium sulfate. It is recommended to use ternary compound fertilizer (14:6:5) and apply 50~55 kg per mu.

Second, rice high-yield formula fertilization method

Organic fertilizer is poured into the soil when plowing the field. 80~90% of the phosphorus and nitrogen fertilizers used as the intermediate fertilizer, and the remaining 10-20% of the nitrogen fertilizers are applied as the split fertilizer or panicle fertilizer, and the potassium fertilizer is applied in the middle growth period (about 45 days after planting); For the mixed fertilizer, the compound fertilizer is used as the middle layer fertilizer once; for the cold soaked zinc deficiency field, 1 kg of zinc sulfate per acre or 0.1~0.2% zinc sulfate solution per acre in the early growth period, spray 2~3 Times, interval 7 to 10 days once. Rice fertilization is a garlic field in the previous crop. After rice transplanting, nitrogen and phosphorus fertilizers are not recommended, and only potassium fertilizer is applied.

Electric Mosquito Swatter

Electric mosquito swatter is a kind of small household appliance products, mainly used to kill mosquitoes, ‌ flies, ‌ moths and other insects. ‌ It through the electronic high voltage technology, the use of 1850V high voltage to effectively destroy these pests, has the advantages of practical, convenient, no chemical pollution, safety and health, so it is widely welcomed, become the summer best-selling small household appliances products. The electric mosquito bat is usually composed of three layers of metal mesh, the outer metal mesh and the middle layer are not directly connected, and maintain a certain distance. When the switch is pressed, the direct current in the battery passes through the oscillation circuit and the boost circuit, eventually reaching a high voltage above 2000 volts. This design allows the mosquito to be waved through the electrostatic field and electrical grid discharge to destroy the insect, without causing harm to the human body. ‌
The main advantages of electric mosquito swatting include:
‌Efficient pest control: can kill a variety of insects in a short time, including mosquitoes, flies and moths.
Safety and health: the use of high voltage electricity instead of chemical agents, to avoid chemical pollution, more environmental protection and safety.
‌Portable and convenient: compact size, easy to carry and use, suitable for home and outdoor use.
No chemical pollution: will not produce harmful chemicals, more friendly to the environment and human body.
The following points should be noted when using an electric mosquito swatter:
‌Avoid using ‌ in humid environment, so as not to affect its high pressure effect.
‌Keep the electric mosquito bat dry ‌ to avoid short circuit or damage caused by moisture.
‌Avoid using ‌ in flammable and explosive environments to prevent accidents.
‌Children should use ‌ under adult supervision to prevent accidental handling or risk of electric shock.
In short, with its high efficiency, safety and environmental protection characteristics, the electric mosquito has become an ideal choice for summer pest control.
