Problems solved by technology

Because the knowledge of scientific planting and scientific fertilization is not high, and due to the shortage of organic fertilizer sources, in the process of planting and management of different crops, the application of nitrogen, phosphorus, potassium, etc., commonly known as large chemical fertilizers, is generally emphasized in order to increase production. Blindly increase the dosage, and over time, the soil structure will deteriorate, some elements will be excessive, and many elements will be deficient, which will lead to excessive element poisoning and various deficiency diseases of crops
In the cultivation of sweet potatoes, there are phenomena such as vigorous growth of potato seedlings, poor ventilation and light transmission, weakened photosynthesis, only seedlings, no caking, and poor quality of potato pieces; Large chemical fertilizers are not suitable for foliar spraying and topdressing, which will reduce the yield and quality of sweet potatoes
At present, in the cultivation and management of sweet potatoes, most farmers still only pay attention to the application of nitrogen fertilizer, and pay attention to the one-time application of base fertilizer, which leads to the imbalance of nutrient elements, resulting in the lack or excess of nutrient elements, resulting in deficiency or excessive element poisoning, which seriously affects sweet potatoes. growth and yield
In addition, the use of nitrogen fertilizer requires a large amount and high cost. The amount of nitrogen fertilizer used is about 30-50 kg per mu, and the excessive use of nitrogen fertilizer is likely to cause soil pollution, which will cause the deterioration of groundwater sources. Therefore, the country does not advocate the use of large amounts of nitrogen fertilizer.

Embodiment 1

[0033] First crush the granular ferrous sulfate, borax, and calcium nitrate raw materials respectively, pass through a 120-mesh sieve to make powder, then weigh 2 kg of ferrous sulfate powder, 3 kg of borax powder, 1.5 kg of calcium nitrate powder and powdered raw materials Mix 42 kg of urea, 34 kg of potassium dihydrogen phosphate, 12 kg of potassium sulfate, 3 kg of zinc sulfate, 1.5 kg of magnesium sulfate, and 1 kg of copper sulfate, and stir evenly to make sweet potato nutrients. The finished product is measured and divided by 1 kg per bag. Bag sealed packaging. It should be stored in a ventilated and dry place. If caking or deliquescence occurs, it will not affect the fertilizer efficiency.

[0034] The content of each effective nutrient element of sweet potato nutrients prepared according to this formula is: nitrogen, 10%; phosphorus, 11.5%; potassium, 14.5%; zinc, 2.5%; iron, 1.5%; boron, 2%; calcium, 1.2%; Magnesium, 1.2%; Copper, 0.2%.

Embodiment 2

[0036] The weighing amount of raw material powder of each component is: urea 47 kg, potassium dihydrogen phosphate 30 kg, potassium sulfate 16 kg, zinc sulfate 2 kg, ferrous sulfate 1 kg, borax 2.5 kg, calcium nitrate 0.5 kg, magnesium sulfate 0.5 kg, copper sulfate 0.5 kg.

[0037] The content of each effective nutrient element of sweet potato nutrients prepared according to this formula is: nitrogen, 13%; phosphorus, 10%; potassium, 16%; zinc, 1.5%; iron, 1%; boron, 1.5%; calcium, 1%; Magnesium, 1%; Copper, 0.1%.

Embodiment 3

[0039]The weighing amount of raw material powder of each component is: 45 kg of urea, 32 kg of potassium dihydrogen phosphate, 14 kg of potassium sulfate, 2.5 kg of zinc sulfate, 1.5 kg of ferrous sulfate, 2.2 kg of borax, 1 kg of calcium nitrate, magnesium sulfate 1 kg, 0.8 kg of copper sulfate.

[0040] According to the sweet potato nutrients prepared by this formula, the content of each effective nutrient element is respectively: nitrogen, 12%; phosphorus, 11%; potassium, 15%; zinc, 2%; iron, 1.2%; boron, 1.2%; calcium, 1.1%; Magnesium, 1%; Copper, 0.15%.

Abstract

The present invention relates to a sweet potato nutrient for planting sweet potato. Said sweet potato nutrient is made up by adopting urea, potassium dihydrogen phosphate, potassium sulfate, zinc sulfate, ferrous sulfate, borax, calcium nitrate, magnesium sulfate and copper sulfate as raw material through a certain preparation process. It not only can be used as basic fertilizer, additional fertilizer, but also can be used for foliage fertilization.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a sweet potato nutrient for planting sweet potatoes and a preparation method thereof. Background technique [0002] In my country's agricultural planting structure, the economic model of interplanting spring and autumn crops is generally adopted. Because the knowledge of scientific planting and scientific fertilization is not high, and due to the shortage of organic fertilizer sources, in the process of planting and management of different crops, the application of nitrogen, phosphorus, potassium, etc., commonly known as large chemical fertilizers, is generally emphasized in order to increase production. Blindly increase the dosage, and over time, the soil structure will deteriorate, and some elements will be excessive, while many elements will be deficient, which will lead to excessive element poisoning and various deficiency diseases of crops. In the cultivati...
