Problems solved by technology

It can be seen that foliar spraying and root fertilization are two conventional ways for crops to supplement selenium. Foliar spraying has the characteristics of fast absorption and high efficiency but is not a slow-acting type. Root fertilization has the characteristics of slow absorption, low efficiency but long-term effect. The reason It is because selenium is solidified in the soil, and the low effective selenium content in the soil makes the root system absorb selenium inefficiently. Therefore, increasing the available selenium content in the soil will greatly increase the selenium content in peanuts

Embodiment 1

[0028] A planting method of selenium-enriched peanuts, comprising the following steps:

[0029] Step 1. Site preparation and ridging: choose sandy loam soil with loose soil, convenient irrigation and drainage, and medium-to-high fertility, and deeply plow and dry the field. Before planting, evenly spread lime per acre to adjust the soil pH. After 10 days of balance, apply 300kg of selenium-containing organic fertilizer per acre , calcium magnesium phosphate fertilizer 50kg, ridges after 10 days of balance;

[0030] Step 2. Seed selection and sowing: From late February to early March every year, sow when the soil temperature at a depth of 4cm from the surface is stable at an average of above 15°C for 5 consecutive days. For sowing, 2 seeds per hole, the sowing density per acre is 18,000 seedlings / mu;

[0031] Step 3. Field management: Spray selenium-containing water-soluble fertilizers at the flowering and pod-setting stages of the peanuts, and evenly spray them on the front a...

Abstract

The invention provides a method for planting selenium-enriched peanuts. The steps include: site preparation and ridge formation, seed selection and sowing, field management, etc.; according to the effective selenium level of the planting soil, 75 kg of lime and 50-60 kg of calcium, magnesium, and phosphate fertilizers are applied per mu, etc. Measures to activate soil effective selenium, base application of selenium-containing organic fertilizer 300-400kg and other measures to increase the effective selenium content in the soil, and at the same time, according to the nutrient demand and nutrient transfer rules of peanuts in different production periods, choose to spray at the needle-setting and pod-setting stages respectively Apply selenium-containing water-soluble fertilizer (selenium content 0.8-1g / mu), thereby improving the selenium content and peanut quality of peanut seeds; the planting method of the present invention has the characteristics of high selenium enrichment efficiency and high utilization rate of selenium element.

Description

technical field [0001] The invention relates to the field of agricultural planting. More specifically, the present invention relates to a method for planting selenium-enriched peanuts. Background technique [0002] Selenium is an essential trace element for humans and animals. It has six biological functions, including improving human immunity, anti-aging, preventing cancer, protecting and repairing vegetative cells, detoxifying and detoxifying, and improving the oxygen-carrying capacity of red blood cells. Selenium deficiency in humans and animals can cause more than 60 kinds of selenium deficiency diseases such as Keshan disease, Kaschin-Beck disease, and cardiovascular disease. According to reports, two-thirds of the world's regions and about 500 to 1 billion people are deficient in selenium, about 72% of counties and cities in my country have selenium deficiency in varying degrees, and one-third of the regions are extremely deficient in selenium. According to the resul...
