Special seed dressing agent for cutting yam for sowing and breeding

Abstract

The invention relates to a special seed dressing agent for diced yam for sowing and breeding. The seed dressing agent is composed of a rooting agent, a bactericide and plant ash, and the components are calculated by weight percentage: 1-15% of the rooting agent, 30-44% of the bactericide, and 55% of the plant ash. The rooting agent is mixed by vermiculite powder, 6-benzylaminoadenine and naphthaleneacetic acid, and its preparation method is: get 1.5 parts of 6-benzylaminoadenine and 0.5 part of naphthaleneacetic acid with 1 ml volume fraction of 95% After the alcohol is dissolved, add water to make the volume to 100 ml, then fully mix with 98 parts of dry vermiculite powder, and dry at 80°C to constant weight; the fungicide is chlorothalonil. Applying the seed dressing agent of the present invention to yam cutting propagation can not only solve the problem that the yam pieces are easy to rot after sowing, but also the rooting and germination of the yam pieces are carried out simultaneously, the emergence rate is high and uniform, and the prevention and treatment of stem rot and fusarium wilt The effect reaches more than 96%.

Description

technical field [0001] The invention relates to a special seed dressing agent for diced yam for sowing and breeding. Background technique [0002] At present, tuber cutting propagation is the main propagation method in yam production. In the prior art, cutting and propagating yam refers to dividing the seed tubers into yam segments dipped in plant ash for disinfection and then sowing. This method has the advantages of simple operation, labor and time saving, etc., but at the same time, the yam segments are severely rotten and the emergence rate is low. The main reason is that only relying on plant ash disinfection cannot prevent pathogenic microorganisms from infecting the cut surface of yam, so that the disease occurs more severely after sowing. At the same time, because yam has the characteristics of rooting and germination, the rapid growth of roots at the initial stage of sowing inhibits germination, which prolongs the emergence period of yam after sowing, and the seedl...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the deficiencies of the prior art, and aims to provide a special seed dressing agent for sowing and propagation of yam cut into pieces. The seed dressing agent is applied to the yam cut into pieces for sowing and breeding, which can effectively solve the problem of the yam cut surface after sowing. The problem of rot can effectively prevent and control diseases and increase the rate of emergence; and, after using the seed dressing, the rooting and germination of yam dandelion are carried out simultaneously, which can effectively improve the problems of long emergence period and irregular seedling phase of yam dandelion after sowing in the prior art
