Fertilizer specially for peanut

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....

AI Technical Summary

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, magnesium, sulfur and trace elements is ignored, resulting in a serious imbalance of soil nutrients, which leads to the growth of peanuts Poor nutrient supply at each stage of development, less number of flowering needles, low seed setting rate, increased empty shell rate, and decreased thousand-grain weight. Not only is it difficult to increase the yield, but the quality and taste of peanut pulp are also deteriorated, and the oil content is also reduced.

Although there are special compound fertilizers for peanuts on the market, there are few types of fertilizers that are targeted according to the soil of different regions and the law of peanut fertilizer absorption, which do not meet the requirements of balanced fertilization and formula fertilization, so they are not suitable for peanut planting needs
