Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention, and are best understood by reference to the accompanying drawings in which:
FIG. 1 is a view of the root of Sedum plumbizincicola before the bactericide of the embodiment of the present invention is sprayed and sterilized;
FIG. 2 is a view of the root of Sedum plumbizincicola after being sprayed and sterilized with the bactericide of the embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.
The method for preventing and treating the root rot of the Sedum plumbizincicola under the high-temperature rainy weather comprises the steps of weighing raw materials according to a formula proportion, wherein the using amount of pyraclostrobin bactericide is 30-40 g/mu, the using amount of bacillus subtilis bactericide is 20-30 g/mu, and the pyraclostrobin bactericide and the bacillus subtilis bactericide form a mixed bactericide which is diluted and then sprayed on Sedum plumbizincicola plants.
Wherein the content of the active ingredients of the pyraclostrobin in the pyraclostrobin bactericide is 25%, and the content of the active ingredients of the bacillus subtilis bactericide is as follows: 1000 billion spores/gram.
A bactericide for preventing and treating root rot and yield reduction of sedum plumbizincicola in high-temperature rainy days is prepared from the following raw materials in parts by weight: 30-40 g/mu, bacillus subtilis fungicide: 20-30 g/mu, wherein the content of the active ingredients of the pyraclostrobin in the pyraclostrobin bactericide is 25%, and the content of the active ingredients of the bacillus subtilis bactericide is as follows: 1000 billion spores/gram.
In this embodiment, the formulation of the mixed bactericide is a suspension or wettable powder.
After the mixed bactericide is sprayed for the first time, the growth condition and the field water accumulation condition of the sedum plumbizincicola plants are observed, when the sedum plumbizincicola plants have the root rot phenomenon again, the using amount of the mixed bactericide sprayed for the second time is the same as the first using amount, the spraying times of the sedum plumbizincicola plants by using the mixed bactericide for each season are not more than two times, and the middle safety interval period is 15 days.
Generally, after planting the Sedum plumbizincicola, spraying the pyraclostrobin and bacillus subtilis mixed bactericide at the beginning of high-temperature rainy days to prevent root rot of the Sedum plumbizincicola. The mixed bactericide can not be used together with other pesticides and other substances, and after the bactericide is sprayed every time, the field ponding condition is closely concerned according to the weather condition, so that the water drainage in the field is kept smooth, and the best pesticide effect is ensured.
Taking a cadmium (Cd) polluted farmland in Hunan Tan City of Hunan province as an example (as shown in figure 1), 11 months in 2017, transplanting the Sedum plumbizincicola.
Before 4 middle ten days in 2018 and before the rainy season comes, selecting sunny evening, mixing and diluting according to the use amounts of 40 g pyraclostrobin bactericide and 30 g bacillus subtilis bactericide per mu, spraying the bactericide on the field sedum plumbizincicola plants, and preventing the sedum plumbizincicola from root rot in high-temperature rainy days.
In 5-month middle ten days in 2018, as shown in fig. 2, compared with a field block which is not sprayed with a bactericide, the probability of occurrence of root rot is greatly reduced, the problem of root rot of rhodiola rosea in 90% of area is effectively prevented and treated, and the growth vigor is good. However, after the temperature rises and precipitation increases, the root rot phenomenon still occurs because part of the land is unsmooth in drainage and much in accumulated water, so that the bactericide is sprayed to the area of the Sedum plumbizincicola for the second time, the bactericide is still the mixed liquid of pyraclostrobin and bacillus subtilis, and the using amount is the same as that of the bactericide for the first time.
And 7 months in 2018, harvesting when the biomass of the sedum plumbizincicola reaches the maximum. The harvested Sedum plumbizincicola is used for continuously transplanting and expanding the repair area, part of the Sedum plumbizincicola is harvested and then is uniformly dehydrated and reduced, and then is incinerated and subjected to harmless treatment.
The field test result shows that the mixed bactericide of pyraclostrobin and bacillus subtilis is sprayed in summer in the south in high-temperature rainy days, so that the root rot problem of the sedum plumbizincicola can be effectively prevented and relieved. Compared with the contrast, after the bactericide is sprayed, the root rot phenomenon is obviously reduced, the sedum plumbizincicola grows vigorously, and the biomass of the sedum plumbizincicola and the repair efficiency of heavy metals are effectively improved. For plots with good drainage conditions, the root rot phenomenon of the sedum plumbizincicola can be effectively prevented and treated by spraying once; for plots with unsmooth drainage and serious water accumulation, after the sedum plumbizincicola is planted, the problem of root rot and yield reduction of the sedum plumbizincicola can be well solved only by spraying the bactericide twice.
