Black peanut planting method

Abstract

The invention relates to a black peanut planting method comprising a plurality of steps such as plot selection; land preparation and fertilization; ridging; disease, pest and weed controlling; reasonable close planting; field management; and timely harvesting. With the black peanut planting method provided by the invention, disease and pest infection and premature aging phenomena can be effectively avoided; stem and leaf functioning period and photosynthesis are prolonged; root system absorption capacity is enhanced; dry matter accumulation is promoted; fruit-setting rate is high; and yield is finally increased.

Description

technical field [0001] The invention relates to a method for planting black peanuts. Background technique [0002] Black peanuts are also known as selenium-enriched black peanuts, black-grained peanuts, and Qingrengu peanuts. Black peanut is a new variety that contains calcium, potassium, copper, zinc, iron, selenium, manganese, 8 kinds of vitamins and 19 kinds of amino acids needed by the human body, and is also rich in selenium, iron, zinc and other trace elements and melanin . Compared with red peanuts, black peanuts have 5% higher crude protein content, 23.9% higher arginine content, 19% higher potassium content, 48% higher zinc content, and 101% higher selenium content. Analysis of the effectiveness of 10 kinds of amino acids with higher content in black peanuts: black peanuts are rich in 18 kinds of amino acids, the total amount of amino acids is 27.57%, second only to black soybeans, and the proportion of essential amino acids accounts for 22.90%. The advantage of ...

Problems solved by technology

[0003] During the planting of black peanuts, it is often found that there are pests such as grubs, mole crickets, and needleworms on the plants, which directly affect the growth of the plants; secondly, in the middle and late stages of black peanut planting, they are most susceptible to leaf spot, rust and leaf spot disease and other diseases, the leaves are diseased, and the nutrients cannot be effectively transported to the roots, which affects the results; in addition, the black peanuts also have premature aging, the top leaves are easy to fall off, and the stems and leaves are prematurely withered, which weakens the absorption capacity of the root system and eventually leads to consequences. It makes the fruiting rate of black peanuts low and affects the yield
