The management after sowing is performed according to a conventional management method of the konjak.
TABLE 1 influence of coating agent of selenium-enriched rhizoma Amorphophalli on the yield and quality of Amimor 128
As can be seen from table 1, after the selenium-rich konjac coating agent is treated, the whole-powder selenium content and the refined-powder selenium content of the anmagic 128 are significantly increased, so the selenium-rich konjac can be stably produced by adopting the selenium-rich konjac coating technology.
Example 2
1. Seed taro selection: selecting seed konjac with the weight of konjac of 100g to 250 g to produce commercial konjac. The selected corm must have the typical characters of the floret konjak, has no disease spots, no damage, no insect mouth and no frostbite, and is not the floret konjak.
2. Pre-treatment of seed taro: and (3) paving the konjak bulb selected in the step (1) on the ground, preparing 200 times of 1.26% Xinjunan acetate aqueous solution, and uniformly spraying the Xinjunan acetate aqueous solution on the konjak bulb until the surface of the konjak bulb is wet.
3. Preparation of a coating agent: 30kg of selenium fertilizer (produced by Jiangsu Tianniang agricultural science and technology Limited company, jiangsu, with the selenium content of 9500 mg/kg) is weighed, 7kg of plant ash, 15kg of fine yellow mud, 100g of selenium-enriched lactobacillus-lactobacillus acidophilus 08001 (from the important dairy laboratory of northeast agriculture university), 200g of microbial additive TM-10 (produced by Nanjing Jiuirun science and technology Limited company), 2000ml of wood vinegar are added, 25L of water is added, and the mixture is stirred and mixed by hand to form the seed taro coating agent.
4. Coating: and (3) taking out the seed taro pretreated in the step (2), lightly putting the seed taro into a container filled with the coating agent in the step (3), and rolling until the seed ball is completely coated with the coating agent.
5. And (3) airing: and (4) taking out the coated seed balls in the step (4), and carefully placing the seeds in a ventilated place for airing.
6. Soil treatment: at 10 days before planting, 1kg of 85% trichloroisocyanuric acid is used per mu of land, mixed with 10kg of fine soil, uniformly spread on the ground surface, immediately subjected to rotary tillage and soil turning, and the soil humidity is kept, so that the sterilization and disinfection effects can be achieved.
7. Sowing: during sowing, after the corm is placed, high-selenium cordyceps militaris culture medium waste (the application amount of sodium selenite is 200 mg/kg) is scattered around the corm to serve as a selenium-rich organic fertilizer raw material, and 60 g/pit is used for further supplementing a selenium source in the growing period of the corm.
TABLE 2 influence of selenium-rich coating agent treatment on the selenium content of each organ of amorphophallus konjac in the leaf expanding period
As can be seen from table 2, in the leaf-spreading period of amorphophallus konjac, after the treatment with the selenium-rich konjac coating agent, the selenium content in the leaves, the petioles and the corms of amorphophallus konjac is significantly increased. Wherein the selenium content in the leaves, the petioles and the corms is that the corms are larger than the petioles and larger than the leaves in sequence, and is respectively 0.3214, 0.7110 and 1.1326mg/kg. It can be seen that the selenium in the coating agent is efficiently absorbed and utilized by the konjak under the action of the selenium-rich lactic acid bacteria.
The embodiment of the invention provides a coating agent for producing selenium-rich konjak and a prepared coated seed, wherein the coating agent comprises the following raw materials in parts by weight: 25 to 30 portions of selenium fertilizer, 5 to 7 portions of plant ash, 10 to 15 portions of yellow mud, 0.08 to 0.15 portion of selenium-enriched lactobacillus, 100.16 to 0.30g of microbial assistant TM-, 1 to 2 portions of wood vinegar and 20 to 26 portions of water. The coating agent can provide a large amount of absorbable selenium sources for the konjac while simply, conveniently and efficiently sterilizing the konjac seeds. By adding the selenium-rich lactic acid bacteria and the microbial assistant, inorganic selenium in the selenium fertilizer can be rapidly accumulated and converted into nano selenium and organic selenium, so that konjak can be conveniently absorbed and utilized. The occurrence of the soft rot of the konjak can be effectively prevented by adding the plant ash and the wood vinegar. By the corresponding planting method, the selenium content in the konjac can be effectively improved, and the standardized and large-scale production of the selenium-rich konjac is facilitated.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
