Problems solved by technology

However, according to the local food safety standard of Hubei Province DBS42 / 002-2014 "Selenium Content Requirements for Organic Selenium-Rich Foods", the selenium content of dried fruits cannot reach the standard of 20μg / 100g. Appropriate artificial addition of exogenous selenium is essential for walnut selenium-enriched cultivation

Embodiment 1

[0023] The invention provides a technical scheme: a selenium-enriched walnut cultivation technique, the method comprising the following steps:

[0024] Step 1: terrain judgment: manually observe the topography of the target area for cultivating selenium-enriched walnuts;

[0025] Step 2: Sampling method: Select the soil sampling method according to the terrain conclusion obtained in step 1. If the target area is small, the terrain is flat, and the soil is uniform, choose the quincunx sampling method. If the target area is medium-sized and the terrain is flat If the terrain is basically complete and the soil is not uniform, the checkerboard sampling method is selected. If the target area is small, the terrain is not flat, and the soil is not uniform enough, the serpentine sampling method is used. The terrain in the embodiment is a medium-sized area, flat terrain, basically complete terrain, and uneven soil, and the serpentine sampling method is adopted;

[0026] Step 3: Soil t...

Embodiment 3

[0059] The invention provides a technical scheme: a selenium-enriched walnut cultivation technique, the method comprising the following steps:

[0060] Step 1: terrain judgment: manually observe the topography of the target area for cultivating selenium-enriched walnuts;

[0061] Step 2: Sampling method: Select the soil sampling method according to the terrain conclusion obtained in step 1. If the target area is small, the terrain is flat, and the soil is uniform, choose the quincunx sampling method. If the target area is medium-sized and the terrain is flat If the terrain is basically complete and the soil is not uniform, the checkerboard sampling method is selected. If the target area is small, the terrain is not flat, and the soil is not uniform enough, the serpentine sampling method is used. The topography in the embodiment is a medium-sized area, flat topography, basically complete topography, and the serpentine sampling method is adopted for soil that is not uniform;

Abstract

The invention discloses a selenium-rich walnut cultivation technology. The method includes the steps of 1, terrain judgment, 2, a sampling method, 3, soil detection, 4, selenium fertilizer allocation,5, selenium fertilizer application, 6, timely picking, 7, fruit preservation and 8, management after picking. According to the method, by performing a soil sample test in a target selenium-rich walnut planting region, the selenium content of plant soil is accurately obtained, the content of selenium absorbed by walnut plants is significantly increased by artificial fertilization, and the seleniumcontent of walnut is higher than the local standard.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a selenium-enriched walnut cultivation technology. Background technique [0002] Walnut, also known as walnut, Qiang peach, is a Juglandaceae plant. Together with almonds, cashew nuts and hazelnuts, it is also known as the world-renowned "four major dried fruits". Walnuts are rich in nutrients, containing 15-20 grams of protein per hectogram, more fat, and 10 grams of carbohydrates; Flavin and other multivitamins. Beneficial to the human body. It is one of the nut foods loved by the common people. [0003] Enshi is the "Selenium Capital of the World". As a trace element beneficial to human health, selenium has become the focus of the health food industry in recent years. Enshi Prefecture has a large area of ​​selenium-rich soil, and Enshi City, Badong County, Xuan'en County, etc. The selenium-enriched areas overlap to a certain extent with the main walnut producing are...
