Embodiment 1
[0021] This embodiment provides a method for complexing potassium fulvic acid to strengthen rice seed selenium nutrient enrichment, and the specific steps are as follows:
[0022] Step 1. Bag the rice seeds: put the sun-dried rice seeds into special high-permeable germination-promoting mesh bags, and the quantity of seeds loaded should not exceed 65% of the maximum capacity of the seed bags. Each seed bag contains 15-20kg of rice seeds, The bag should not be too big, it should be sealed for later use;
[0023] Step 2. Displacement placement layer by layer: Put the bagged rice seeds into the seed bag backing plate in the permeable container according to the layers. Oxygen, water, heat;
[0024] Step 3. Soak the seeds to accelerate germination until the seeds germinate and reach the state of broken chest:
[0025] According to the number of rice seeds to be nutrient enriched and strengthened, on the principle of 10-15cm higher than the top edge of the seed bag in the water-per...
Embodiment 2
[0032] In this embodiment, the method for enriching selenium nutrition in rice seeds by complexation with potassium fulvic acid is used to enrich the selenium nutrition in Longyang No. 20 rice seeds. The specific methods are as follows:
[0033] Step 1. Bag the rice seeds: Put the rice seeds of Longyang No. 20 into special high-water-permeable germination-promoting net bags. The quantity of seeds is 55% of the maximum capacity of the seed bags. Each seed bag contains 15kg of rice seeds. The seed bag should not be too large, and it should be sealed for later use;
[0034] Step 2. Displacement placement layer by layer: Put the bagged rice seeds into the seed bag backing plate in the permeable container according to the layers. Oxygen, water, heat;
[0035] Step 3. Soak the seeds until the rice seeds germinate and reach the broken chest state:
[0036] According to the number of rice seeds to be nutrient-enriched and strengthened, on the principle of 15cm higher than the top ed...
Embodiment 3
[0042] In this embodiment, the method for enriching selenium nutrition in rice seeds by complexation with potassium fulvic acid is used to enrich the selenium nutrition in Nongxiangdao No. 7 rice seeds. The specific methods are as follows:
[0043] Step 1. Pack rice seeds into bags: Put the sun-dried Nongxiangdao No. 7 rice seeds into special high-permeable germination-promoting mesh bags. The number of seeds packed is 60% of the maximum capacity of the seed bag, and each seed bag contains 20kg of rice seeds. , the seed bag should not be too large, and it should be sealed for later use;
[0044] Step 2. Displacement placement layer by layer: Put the bagged rice seeds into the seed bag backing plate in the permeable container according to the layers. Oxygen, water, heat;
[0045] Step 3. Soak the seeds until the rice seeds germinate and reach the broken chest state:
[0046] According to the number of rice seeds to be nutrient-enriched and strengthened, on the principle of 10...
