Embodiment 1～4

[0024] In Examples 1-4, see Table 1 for the distribution ratio of each component of the special seed dressing agent for yam cutting and propagation. The rooting agent, fungicide and plant ash are uniformly mixed by a conventional method to obtain a special seed dressing agent for cutting and propagating yam. After mixing the Chinese yam with the special seed dressing agent according to the aforementioned method, it was directly sown in the field. 20 days after sowing, see the rooting and sprouting of yam Duanzi Figure 1~3 ,From figure 1 It can be seen that after using the seed dressing agent of the present invention, the Chinese yam rooting is early and sprouting is also early (rooting and sprouting are carried out simultaneously), the emergence time is relatively concentrated, the emergence rate is high, and the seedling phase is neat; The yam Duanzi treated with seed dressing mainly takes root, but rarely sprouts, the emergence rate is low, and the seedlings are inconsist...

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...
