How to apply sweet potato? How to make sweet potato high yield fertilization skills

The sweet potato grower Zhang Daye, who has been planting sweet potatoes for several generations at home, has 5 mu of sweet potato land at home, and the yield per mu is more than 8,000 kilograms. I think the output is not bad. The son who came back from the field learned about the incident and told Uncle Zhang that the sweet potato in the classmate’s home was over 10,000 yuan. Uncle Zhang is very depressed. He has worked hard and planted. Every joint is careful. How can he be so big with others? So he started looking for an expert to help him see what is going on, how can he do the same with others? To over 10,000 yuan per mu?

You can't know the fertilization skills that make sweet potato high-yield? When the experts came to the ground, they immediately knew what went wrong. It turned out that Zhang had a problem in the fertilization process. When the fertilizer was applied, there was no fertilization, which caused the roots to not absorb. Well, when the experts saw it, they immediately gave Zhang Uncle a set of fertilization plan, and guaranteed that the output would be no problem, and the yield per mu could be over 10,000.

First, fertilizer water filling

Sweet potato is a potassium-producing crop. During the tuber expansion period, the fertilizer should be used to fill the rhizosphere soil with potassium fertilizer, which meets the needs of potassium in the late sweet potato. Generally, in the end of August, 1% potassium dihydrogen phosphate solution is used for 100-150 kg per mu. For the de-fertilized plot, 100 kg of nitrogen, phosphorus and potassium mixture can be infused and poured along the crack. In the case of persistent dry weather, it is necessary to timely pour the bulge water in a place where conditions are met, but it is not advisable to water the water within 20 days before harvesting to avoid reducing the storability of the roots. In case of autumn, it is necessary to clear the ditch and drain in time to prevent the root rot from causing a reduction in production.

Second, foliar spray fertilizer

In the sweet potato expansion period, the foliar fertilizer is sprayed, and the potassium dihydrogen phosphate solution is used for foliar spraying. Another point is that the sweet potato planted this year has not been turned over as in previous years, but has been carried out to prevent the loss of sweet potato nutrition.

1. For the general field, spray 0.4% to 0.5% of urea and potassium dihydrogen phosphate mixture, spray once every 7 to 10 days, spray a total of 2 to 3 times, spray a fertilizer solution of 70 per acre. ~100 kg, spraying time is suitable for sunny and evening.

2. 0.2% potassium dihydrogen phosphate solution or 2% to 3% superphosphate leaching solution may be sprayed on fields with high growth potential and high fertility level.

3. 0.5% urea solution can be sprayed on the hilly slopes, plain sands or fields with premature aging tendency.

Through the above fertilization method, Zhang Daye's sweet potato has been improved very well. Regardless of the appearance, the growth, the head is better than last year, and Zhang uncle is happy. Therefore, you can also use the above sweet potato fertilization method to ensure that the sweet potato grows much better.
