Embodiment 1

[0011] Select plots with good drainage and watering conditions, rich in sand and organic matter, free from a large number of grubs, nematodes and other underground pests to plant new varieties of peanuts with high oleic acid. Huayu 19, a new high-oleic peanut variety, was sown on April 30. Covering with black and white plastic film, the middle 30 cm width of the plastic film is white, and the 25 cm plastic film on both sides is black, the thickness of the plastic film is 0.005 mm, and the width of the plastic film is 80 cm. Apply 6500 kg of chicken manure per mu. Apply 10 kg of phosphorus pentoxide, 10 kg of pure nitrogen, and 12 kg of potassium oxide per mu; the ratio of inorganic fertilizer and coated controlled-release fertilizer is 2 / 3. Spray 0.3% potassium dihydrogen phosphate aqueous solution 2 times 6 weeks after flowering, with an interval of 8 days each time. In the later stage of peanut growth, spray 15 grams of Zhuangbaan growth regulator per acre to prevent peanu...

Abstract

The invention discloses a culture method for improving the oleic acid content of peanuts. The method comprises the following steps: selecting a new variety of peanuts with high oleic acid; sowing in an optimum period; covering with a black-and-white plastic film; additionally applying an organic fertilizer, inorganic fertilizer and coated control-releasing fertilizer for mixed use; spraying foliar fertilizer in a later period; and adopting a chemical adjusting method and an irrigation method to increase soil temperature. The method is utilized to plant peanuts so as to improve the per-mu yield of the peanuts by 20-40 kg, improve the oleic acid content of peanuts by 3-10 percent and have favorable economic benefits and social benefits.

Description

technical field [0001] The invention relates to a cultivation method for increasing the oleic acid content of peanuts, belonging to the technical field of peanut cultivation. Background technique [0002] Peanut is an important oil crop and economic crop in my country. During the "Tenth Five-Year Period", the average peanut planting area in my country is about 5 million hectares, and the output is about 14 million tons, ranking first in the world and accounting for more than 40% of the world's total output. Peanut is one of my country's traditional export bulk agricultural products, exported to more than 100 countries and regions, with an annual export volume of 778,000 tons, about more than 600 million US dollars. Over the years, my country's peanuts and peanut products have occupied an important position in the world's peanut export trade. Statistics from the Food and Agriculture Organization of the United Nations (FAO) show that from 2000 to 2005, the total export volum...
