Description

Tuber crop bud inhibitor and preparation method and application thereof
Technical Field
The invention relates to the technical field of crop storage, in particular to a tuber crop bud inhibitor and a preparation method and application thereof.
Background
Tuber crops such as potatoes, sweet potatoes, garlic, onions, ginger and the like after harvesting sprout after a dormancy period of 2-3 months, quality degradation caused by sprouting is the biggest problem existing in the storage period, and the loss caused by sprouting accounts for 20% -25% of the total yield. In addition, toxic substances such as solanine and the like can be generated by the sweet potato after germination, and huge potential safety hazards are brought to consumers. Therefore, the artificial inhibition of sprouting of tubers with shelf life is a key problem to be solved urgently in the storage research field and the processing industry at present.
The use of chemical agents is one of the main means of reducing germination rate at present. The chemical bud inhibitor used in the prior art mainly comprises pendimethalin, butralin, flumetralin, uniconazole, chlorpropham and the like. The chemical agent has the characteristics of low cost, certain effect, high residue, stable structure, difficult decomposition and the like, is easy to accumulate in plants, and further causes potential harm to human bodies. Changing the physical conditions of the storage space is another main means of controlling germination, but controlling germination by physical conditions requires a large investment of funds for the construction of infrastructure, and has high construction, operation and maintenance costs, which is difficult to popularize in farmers.
It has been found that many plants contain active substances with bud inhibiting activity. The plant source active substance has better safety to non-target organisms such as people, livestock, natural enemies and the like, becomes one of hot spots for the research of the bud inhibitor, and has good development and application prospects. However, the bud inhibition effect of the plant active substance is often inferior to that of the chemical agent, so that the plant active substance is often used together with the chemical agent in actual use, and if the plant active substance is used alone, a large amount of the plant active substance is required, otherwise, the ideal bud inhibition effect is difficult to achieve.
Disclosure of Invention

Test example 1
The newly harvested potatoes with identical maturity and size and without mechanical damage of the netherlands are randomly grouped, 10kg of each group is used as a blank control, no treatment is performed on one group, and the rest groups are respectively subjected to bud inhibition treatment by using the tuber crop bud inhibition fumigants prepared in the examples 1-7 and the comparative examples 1-4.
Sealable transparent containers (0.25 m.times.0.25 m.times.0.5 m) were prepared for each group of potatoes, respectively.
The methods of treatment with the tuber crop bud inhibiting fumigants of examples 1 to 7, comparative examples 1 to 4 were: placing the sealable transparent container in an environment with the temperature of 15 ℃ and the humidity of 95% in an opened state, so that the temperature and the humidity in the sealable transparent container reach the temperature of 15 ℃ and the humidity of 95%; potatoes are placed in each group of containers, the containers are immediately sealed after the surfaces of the potatoes are uniformly sprayed with the bud inhibitor (5 milliliters of the bud inhibitor is sprayed per kilogram of potatoes), and the sprouting and spoiling conditions of the potatoes are observed on the 30 th day, the 45 th day and the 60 th day respectively, and the potatoes are compared with a blank which is not sprayed with the bud inhibitor.
The germination rate calculation method comprises the following steps:
germination rate (%) =number of sprouts/total number of sprouts×100
The decay rate calculation method comprises the following steps:
rotting rate (%) =rotting potato weight/total potato weight×100
The test results are as follows:
table 7 experimental results on potato
Test example 2
Fresh ginger with the same maturity and size and without damage is randomly grouped into 10kg each group, one group is blank control, no treatment is carried out, and the other groups are respectively subjected to bud inhibition treatment by using the tuber crop bud inhibition fumigants prepared in the examples 1-7 and the comparative examples 1-4.
Sealable transparent containers (0.25 m.times.0.25 m.times.0.5 m) were prepared for each group of potatoes, respectively.
The methods of treatment with the tuber crop bud inhibiting fumigants of examples 1 to 7, comparative examples 1 to 4 were: placing the sealable transparent container in an environment with the temperature of 15 ℃ and the humidity of 95% in an opened state, so that the temperature and the humidity in the sealable transparent container reach the temperature of 15 ℃ and the humidity of 95%; ginger is placed in each group of containers, the containers are immediately sealed after the germination inhibitor is uniformly sprayed on the surfaces (5 milliliters of germination inhibitor is sprayed on each kilogram of ginger), and the germination and decay conditions of the ginger are observed on 14 days, 21 days and 30 days respectively, and are compared with a blank which is not sprayed with the germination inhibitor.
Table 8 results of experiments on ginger
From the above experimental data of test examples 1 and 2, it can be seen that the germination rate of potatoes in 30 days, 45 days and 60 days is respectively lower than 6.9%, 7.7% and 8.8%, the germination rate of ginger in 14 days, 21 days and 30 days is respectively lower than 1.5%, 3.8% and 4.9%, and the germination rate is lower than 10.6% by using the tuber crop bud-inhibiting fumigant provided by the invention in 1 to 7, which indicates that the germination inhibiting effect of tuber crops in each example is remarkable.
Comparative examples 1 and 2 respectively and independently contain carvacrol or carvone, but after the bud inhibitor obtained in comparative examples 1 and 2 is used, the germination rate and the decay rate are both higher than those of example 2, which shows that carvacrol and carvone have synergistic effect, and the effect of the two is better than that of the carvacrol and carvone which are independently used.
Comparative examples 3 and 4 each replaced carvone or carvacrol with peppermint oil, although peppermint oil is a natural active substance known to have bud inhibition and preservative effects, from the data effect, the bud inhibition agents obtained in comparative examples 3 and 4 are higher in germination rate and decay rate than those obtained in example 2, and it is shown that interaction does not exist between different substances, even though interaction is possible, the interaction is not necessarily synergistic, and ideal effects can be obtained by compounding natural substances which are not inhibited and preserved at will.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the invention.
