Embodiment 1
[0028] A planting method for improving anthocyanins in black rice, comprising the following steps:
[0029] (1) Seed treatment period: sun-dry the black rice seeds for disinfection, dry them in the sun for 2 days at 8:00-18:00 on a sunny day, and turn them every 1 hour. The solution is soaked at normal temperature for 48h, and the amount of sodium selenate used per 100g of dry black rice seeds is 1.3mg. The sodium selenate solution submerges the rice seeds and is 10cm higher than the rice seeds. After taking it out, it accelerates germination and sows;
[0030] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 16:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5500mL, and then ventilate and harden the seedling;
[0031] (3) Paddy field management: According to the conventional planting density and method, plant the seedlings in the paddy field, spray 100mg / L sodium selenate so...
Embodiment 2
[0035] A planting method for improving anthocyanins in black rice, comprising the following steps:
[0036] (1) Seed treatment period: Sun-dry the black rice seeds for disinfection, dry them in the sun for 3 days at 8:00-18:00 on a sunny day, turn them over every 1 hour, the thickness of the seeds when they are dried is 8-15cm, and then use sodium selenate The solution is soaked at normal temperature for 48 hours, and the amount of sodium selenate used per 100 g of dry black rice seeds is 1.5 mg. The sodium selenate solution submerges the rice seeds and is 10 cm higher than the rice seeds. After taking it out, it accelerates germination and sows;
[0037] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 18:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5000mL, and then ventilate and harden the seedling;
[0038] (3) Paddy field management: According to the conventional plant...
Embodiment 3
[0042] A planting method for improving anthocyanins in black rice, comprising the following steps:
[0043] (1) Seed treatment period: sun-dry the black rice seeds for disinfection, dry them in the sun for 2 days at 8:00-18:00 on a sunny day, and turn them every 1 hour. The solution is soaked at normal temperature for 48h, and the amount of sodium selenate used per 100g of dry black rice seeds is 1.4mg. The sodium selenate solution submerges the rice seeds and is 10cm higher than the rice seeds. After taking it out, it accelerates germination and sows;
[0044] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 17:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5300mL, and then ventilate and harden the seedling;
[0045] (3) Paddy field management: According to the conventional planting density and method, plant the seedlings in the paddy field, spray 100mg / L sodium selenate so...
