Problems solved by technology

Peanuts grown in selenium-deficient soil usually do not meet the selenium-enriched standard, and the acidic soil in the south is more prone to calcium deficiency, resulting in empty shells or not full peanuts, and the corresponding yield is also low, which cannot meet the needs of commercialization
[0003] Through the above analysis, the problems and defects in the prior art are: the selenium content of peanuts planted in selenium-deficient soil is relatively low, and the supplementary effect on human selenium is relatively poor; Plump, low yield of peanuts, unable to meet the needs of commercialization

Embodiment 1

[0053] Embodiment 1: (compound fertilizer reduction, increase the application of calcium magnesium phosphate fertilizer, spray selenium)

[0054] Step 1: Select a field, take a soil sample to detect that the total selenium content is 0.39mg / kg; the exchangeable calcium content is 3.19cmol / kg; the pH value is 6.15.

[0055] Step 2: Deeply plow the land with a tractor, evenly spread 1000kg of fully decomposed farmyard manure per 666.7㎡ in the soil, and use the tractor to rotate and cultivate the ridges. The width of the ridge is 55cm, the width of the ridge is 25cm, and the height of the ridge is 20cm. Row sowing ditch with a depth of about 10cm and a row spacing of about 25cm. Spread 25kg of compound fertilizer and 50kg of calcium magnesium phosphate fertilizer per 666.7㎡ in the sowing ditch, and mix well with the soil.

[0056] Step 3: Designate test plots, each plot is 10㎡, repeat 3 times.

[0057] Step 4, sow with coated peanut seeds, with a plant spacing of about 12 cm, an...

Abstract

The invention belongs to the technical field of crop cultivation, and discloses a high-yield cultivation method of selenium-rich peanuts. The method comprises the following steps: selecting a plot with flat terrain, deep soil layer, soil selenium content of less than or equal to 0.4 mg / kg and convenient irrigation and drainage as a planting area; deeply plowing soil; applying completely decomposedfarmyard manure to the soil, then conducting rotary tillage to loosen and flatten the land, and conducting ridging and row opening; performing compound fertilizer reduction: spreading a compound fertilizer and a calcium magnesium phosphate fertilizer in the seeding furrows, and uniformly mixing the fertilizers with the soil; coating seeds; sowing the seeds; spraying a pre-emergence herbicide after sowing; keeping soil moist; spraying a liquid selenium fertilizer in the flowering and needle setting period and the pod bearing period; and performing pest control. According to the method, the external environment of peanut cultivation is optimized, the growth vigor of peanuts is better, and the yield is higher; and the liquid selenium fertilizer is sprayed in the flowering needle period and the pod bearing period of the peanuts, sufficient supply of a selenium fertilizer in areas with low soil selenium content can be achieved, and the selenium content in the harvested peanuts is increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a high-yield cultivation method for selenium-enriched peanuts. Background technique [0002] At present: Peanut is also known as "longevity fruit". Its fruit is rich in protein, fat, sugar, vitamin A, vitamin B6, vitamin E, vitamin K, and mineral calcium, phosphorus, iron and other nutrients. It contains 8 kinds of nutrients that the human body needs. Essential amino acids and unsaturated fatty acids, including lecithin, choline, carotene, crude fiber and other substances. It can promote the development of human brain cells and enhance memory. Peanut is an important economic crop in my country, which has a wide range of uses and occupies an important position in the national economy. Selenium is one of the essential trace elements for the human body. It has a variety of immune and biological functions. Selenium can improve human immunity. Selenium supplemen...
