Problems solved by technology

[0015] However, the rural peanut growers in my country do not know much about the biological basis of peanut cultivation, and they do not know much about the growth characteristics of peanuts in the growth stages such as seed germination, seedling emergence, seedlings, flowering and needle setting, pod setting, and full fruit maturity. , nutritional characteristics, and the law of fertilizer absorption are not well understood, and the blindness of planting peanuts and applying fertilizers leads to low yield per unit area, only about 130-150 kg
Especially under the influence of traditional fertilization methods, when farmers plant peanuts, the types of fertilization and nutrient allocation are extremely unreasonable, and the reasonable combination of nitrogen, phosphorus, potassium, calcium, magnes

Embodiment 1

[0034] For the area north of the Yangtze River, the total nutrient range is 30%-36%, and the weight percentage of the formula is N:P:K=6-8:10-12:14-16. The soil in the north of the Yangtze River is mostly alkaline, and the pH The value is generally greater than 8, so the special fertilizer for peanuts must be acidic, and the PH value should be controlled at 5.0-6.0, which can be achieved by adjusting the ratio of raw materials. The production formula is designed as follows:

[0035] Urea: 40-80 kg Ammonium sulfate: 50-100 kg

[0036] Potassium chloride: 130-150 kg Potassium sulfate: 50-70 kg

[0037] Superphosphate: 200-300 kg Monoammonium phosphate: 80-120 kg

[0038] Ammonium nitrate: 40-50 kg Special filler No. 1: 30-60 kg

[0039] Boron fertilizer: 10 kg Molybdenum fertilizer: 10 kg

[0040] Zinc fertilizer: 20 kg

Embodiment 2

[0042] For the area south of the Yangtze River, the total nutrient range is 25-30%, and the weight percentage of the formula is N:P:K=10-12:6-7:9-10. The soil in the area south of the Yangtze River is mostly acidic, and the general pH value If it is less than 5.5, it is appropriate to control the PH value of peanut fertilizer to 8.0-9.0, which must also be achieved by adjusting the ratio of raw materials. The production formula is designed as follows:

[0043] Urea: 80-120 kg Ammonium sulfate: 50-100 kg

[0044] Potassium chloride: 80-100 kg Potassium sulfate: 30-50 kg

[0045] Superphosphate: 200-300 kg Monoammonium phosphate: 50-80 kg

[0046] Ammonium nitrate: 40-50 kg Special filler No. 1: 60-100 kg

[0047] Boron fertilizer: 10 kg Molybdenum fertilizer: 10 kg

[0048] Zinc fertilizer: 20 kg

[0049] Because peanuts are sulfur-loving and anaerobic crops, too much chloride ions will affect the growth and development of peanuts and the quality of the pulp. At the same t...

Abstract

The present invention relates to a kind of special fertilizer for peanut. When the soil is alkaline, the total nutrient range of said special fertilizer is 30%-36%, and the weight percentage of its formula is N:P:K=6-8:10-12:14-16, and when the soil is acidic, the total nutrient range of said special fertilizer is 25-30%, and the weight percentage of its formula is N:P:K=10-12:6-7:9-10. Said special fertilizer can raise average unit yield of peanut by about 30-40%, and can raise its thousand-grain weight by about 10% and raise its oil content by 6-8%.

Description

technical field [0001] The invention relates to a special fertilizer, in particular to a special fertilizer for peanuts. Background technique [0002] Peanut is an important oil crop in my country, and it is planted in a wide range, from the hot south to the cold north, from the west of Xinjiang to the east coast. Peanuts are widely used. In addition to being used as oil, they also have many uses in food, chemical industry, and medicine. Peanut stems and leaves are rich in nutrients and are excellent feed, and peanut shells are industrial raw materials. Planting peanuts, because they are leguminous plants, root nodules can fix nitrogen and improve soil fertility. [0003] The growth and development stages of peanut go through seed germination, seedling emergence, seedling, flowering and needle setting, pod setting and maturity. Peanut is a leguminous plant, and peanut rhizobia can fix free nitrogen in the soil air for its own nitrogen nutrition. Peanut absorbs nutrients....
