I. Features of the fertilizer applicator
The fertilizer applicator can directly apply chemical fertilizers to the soil below the roots of crops, and can adjust the amount of fertilizer and the depth of fertilizer application according to the different needs of crops . Compared with the current fertilization method of farmers, the use of fertilizer applicators can save more than half of the chemical fertilizer, increase the fertilization rate by about 4 times, and increase the yield by about 15%. Using a fertilizer applicator has the following advantages:
1. Fertilizer saving: using a fertilizer applicator can save more than 40% of chemical fertilizers, and the crop yield will not decrease.
2. Labor saving: no need to bend over, no need to dig soil, chemical fertilizer can be applied to the soil under the roots of crops.
3. Labor saving: one person fertilizing with a fertilizer applicator is faster than 4 people digging a pit to apply fertilizer. 4 acres of land can be applied in one day.
4. Minimal damage to the mulch: After laying the mulch, the mulch over 10 square centimeters should be damaged at least when fertilizing the pit, while the fertiliser only damages 2 square centimeters of the mulch.
5. It can reduce the damage to the root system of the crops caused by the planing pit: the damage to the root system of the crops is small, and the increase in yield is certain.
6. Make the amount of fertilization uniform, the fertilization depth consistent, and the fertilization distance basically the same, which is very beneficial to the growth of crops, and the increase in yield is also certain.
7. Top dressing can be done in advance: using a fertilizer applicator, after the crops are set, you can put chemical fertilizers into the soil at the roots of the crops.
8. It can reduce soil compaction: because the fertilizer is applied to the proper position of the soil below the root of the crop, it is fully absorbed by the crop and there is very little residual chemical fertilizer in the soil, reducing environmental pollution, and the soil is not easy to harden and harden.
Second, the scope of application of the fertilizer applicator
1. Applicable fertilizers: urea, compound fertilizer, diammonium phosphate and other solid granular fertilizers.
2. Suitable crops: crops with a single plant and a large plant spacing, such as corn, cotton, sorghum, sunflower and other food crops, green peppers, beans, tomatoes, eggplants, potatoes and other vegetable crops, cucumbers, watermelons , pumpkin, melon and other melon crops, coffee trees, tea trees, flowers, fruit trees, medicinal materials and other economic crops.
Three, the economic benefits of the fertilizer applicator
Using the fertilizer applicator can save 100 yuan a day:
1,4 Individual digging and fertilizing is not as fast as a fertilizer applicator
If one person fertilizes four acres of land a day, then 3 labors are saved a day. One labor is worth at least 15 yuan, and 3 labors are 45 yuan (farmers ask people to help, either directly calculate the wages, or do not pay wages but have to pay people to eat and drink).
2. It saves half of the fertilizer compared with the traditional fertilization method, and the crops are guaranteed not to reduce the yield.
The saved fertilizer is actually saved from the waste of the previous fertilization method. fertilizers, not cutting corners on crops. One mu of land can easily save 10 kg of chemical fertilizer, and 4 mu of land can save 40 kg. 40 kg of urea is worth 60 yuan. Combined, you can save $105 a day. If you save 40 kilograms of diammonium, it is more than 80 yuan, and the two combined can save more than 120 yuan a day.
3. Rental income
The fertilization period is seasonal. After your own crops are dry in one day, you can rent out the fertilizer applicator. How much does it cost to rent a day? 10 yuan should be fine, right? If you rent it out for 5-10 days a year, you can earn 50-100 yuan.
In summary, the fertilizer applicator has many functions, such as low price, strong practicability, improving yield and fertilizer utilization rate, reducing labor intensity, and reducing pollution, etc. It is completely suitable for the production and operation of households. Activities, especially in water-scarce areas and crops cultivated with plastic film, should be promoted on a large scale.
