The market standard price is 125 yuan per bag.
1. Wolft controlled-release fertilizer is a high-end technology fertilizer. It is a national 948 key project and the transformation result of the Science and Technology Leapfrog Plan of the Ministry of Agriculture. It has won five national patents. Its technical level is internationally leading and has filled the gap. Domestic blank.
2. Coat the fertilizer with a high-tech smart film (active polymer) to control the release of fertilizer nutrients and achieve a fertilizer with a nutrient release rate consistent with the crop nutrient demand. . Some high-end quick-acting fertilizers are added to Wolft controlled-release fertilizer (special for corn), which works together quickly and slowly. It releases nutrients synchronously according to the growth needs of corn, ensuring that nutrients are not lost or wasted. They can be replenished when they are in short supply, and there is no excess in the early stage. , no fat loss in the later stage.
3. Advantages of smart film controlled-release fertilizer (special for corn):
1. Increased yield and efficiency
Compared with traditional fertilizers, the fertilizer utilization rate is increased by 0.5-1 times. The corn grows robustly, has a well-developed root system, dark green leaves, strong stems, large ears, no baldness, and many grains. , grain weight, and yield increased significantly.
2. Save labor and time
One-time fertilization, corn is only fertilized once in its life, and there is no need for top dressing, which saves a lot of labor and reduces production costs.
3. Improve crop quality
Nutrient release is in line with the absorption rules of corn. Corn grows well and can provide sufficient nutrients during the maturity period of corn to ensure the optimal maturity of the crop. The grains are plump, the thousand-kernel weight is increased, and the ability of corn to resist drought, disease and lodging is enhanced.
4. Environmental protection and conservation
Due to the protection of the intelligent membrane, the waste of volatilization, leaching and fixation of nitrogen, phosphorus, potassium and other elements is effectively avoided, and the waste of salt, alkali and other elements is significantly improved. The soil is non-toxic, which greatly protects the ecological environment.
IV. Application method and dosage:
Basic application: Experts recommend applying about 30-40 kilograms per mu. The specific dosage can be determined according to local conditions with reference to the actual local soil conditions, and the amount can be increased or decreased appropriately.
1. Pay attention to whether the fertilizer should be applied in trenches or holes. Experts recommend that broadcasting is not recommended to avoid artificial waste of fertilizers; soil should be covered in time after fertilization. The earlier the fertilization time, the more fully utilized the nutrients will be.
2. When applying fertilizer, attention should be paid to keeping a distance of 6-10 cm between the fertilizer particles and the seeds or crop roots to prevent burning of seeds, roots and seedlings.
