T/ANJX 0027-2026 Seen-enriched protein mulberry production technical specification with selenium fortification

Scope

This document specifies the cultivation and management techniques for producing selenium-enriched protein mulberry trees by foliar spraying of organic selenium solution, including the selection of selenium sources, spraying periods, methods, concentrations, and quality control, etc. This document is applicable to the cultivation of protein mulberry trees for the production of selenium-enriched livestock products. Selenium sources and spraying requirements Selenium sources The organic selenium solution used for spraying should be a selenium-enriched specialized foliar fertilizer containing potassium selenium phosphate, which should comply with relevant national registration and safety standards. Spraying periods and concentrations During the growth season of protein mulberry trees (from April to November each year), foliar spraying should be carried out in the following two stages: a) Spraying during the growth period: After the mulberry leaves have fully unfolded, spray an organic selenium solution with a concentration of 180 mg/kg; b) Spraying before harvest: Spray an organic selenium solution with a concentration of 200 mg/kg 15-20 days before harvest. Each stage of spraying should be carried out in two sessions, with an interval of 15 days between them. Spraying methods a) The spraying time should be selected on a cloudy day or after 3 PM on a sunny day; b) The spraying should evenly cover the front and back sides of the leaves; c) If the spray solution is washed away by rainwater within 4 hours after spraying, it should be reapplied promptly; d) A suitable amount of adhesion aids can be added to the selenium solution to improve the absorption efficiency.
