3. Reasonable top dressing
In the middle 7 th month, reasonable topdressing is needed; 20ml (500 times of water) of brassinolide with the mass fraction of 0.01 percent, and after 50kg of monopotassium phosphate is added with 50kg of water, carrying out leaf surface spraying treatment, wherein the spraying treatment is carried out once every 2 weeks for 4 times in total, and the spraying treatment is generally carried out in the morning and evening, so that high-temperature evaporation can be reduced;
applying 10kg of potassium sulfate compound fertilizer and 2.5kg of mineral potassium fulvate per mu, wherein the potassium content of potassium sulfate is 48%, the fulvic acid content in the mineral potassium fulvate is 40%, and the application is performed once every month for 3 times continuously.
4. "leafing" treatment
The bulbil konjak generally has a 'leafy' phenomenon in the last 8-9 months, and the leafy phenomenon seriously consumes the nutrients of the underground bulb. Therefore, when the second and third leaves start to push up the soil, the leaves are manually cut off. 10g of 20% by mass of thiediazole copper is mixed with 30kg of water, the wound and the whole plant are sprayed, and the thiediazole copper is continuously sprayed for 3 times every 1 week to prevent and treat the diseases.
The above examples 1 to 3 are specific examples of the present invention, and taking example 1 as an example, it was found that the amorphophallus bulbifer has the characteristics of vigorous "single-leaf growth" (as shown in fig. 1), increased number of leaf surface bulbels (as shown in fig. 2), increased weight of single leaf surface fruits (as shown in fig. 3), prolonged growth period of the whole specific amorphophallus bulbifer by 25 days, increased number of leaf surface corms by 4-5 times, increased weight by 2-3 times, and increased weight of underground corms (as shown in fig. 4), and effectively solved the problems of small number of aerial corms and poor quality of the amorphophallus bulbifer.
TABLE 1 Effect of illumination time on the growth potential of amorphophallus bulbifer plants
| Shading treatment | Plant height (m) | Diameter of petiole (cm) | Bulb weight (kg) |
| All-weather shady (6 dot-18 dot) | 1.85±0.23 | 4.12±0.39 | 2.55±0.38 |
| Timing shade (10 dot-17 dot) | 1.61±0.19 | 3.86±0.45 | 2.96±0.27 |
As can be seen from Table 1, the illumination time has a great influence on the production of konjak plants, and the proper reduction of the shading time has an obvious effect on the growth of the plants and the enlargement of the bulbs.
TABLE 2 influence of growth regulators on the growth potential of amorphophallus bulbifer plants
As can be seen from Table 2, the growth of amorphophallus bulbifer and the enlargement of bulb were significantly different with the growth regulators at different concentrations. Wherein, the 18 percent chlocholene naphthylacetic acid wettable powder-Discapeg-Shuangfeng 50 times of the dilution effect is best.
Comparative example 1
Comparative example 1 provides a method for producing seed tubers, the specific steps being the same as in example 1, except that:
replacing 18 percent of chlorocholineacetic acid with 0.1 percent of S-abscisic acid 50 times of diluent.
Comparative example 2
Comparative example 2 provides a method for producing seed tubers, the specific steps being the same as those of example 1, except that:
replacing 18 percent of chlorocholic naphthylacetic acid with 50 times of prohexadione calcium diluent with the mass fraction of 5 percent.
Comparative example 3
Comparative example 3 provides a method for producing seed tubers, the specific steps being the same as those of example 1, except that:
the 18 percent of chlorochole naphthalene acetic acid is replaced by a diluent with the mass fraction of 50 times that of the Naese ziqi.
Comparative example 4
Comparative example 4 provides a method for producing seed tubers, the specific steps being the same as those of example 1, except that:
the multi-leaf removing treatment is not carried out, and the additional fertilizer and the multi-leaf growth are kept in the growth period.
TABLE 3 influence of leafy removal and topdressing treatment on the growth of amorphophallus bulbifer
| Different treatment | Number of leaf surface corms | Leaf surface corm weight g | Underground bulb weight (kg) |
| Comparative example 4 | 3-7 | 3.64±2.45 | 3.05±0.26 |
| Top dressing and multi-leaf removing | 18-25 | 7.15±1.98 | 3.45±0.31 |
As can be seen from Table 3, the control group (CK) of no top dressing and leafy growth in the growing period was found to have an obvious effect on the formation of leaf surface bulbs with the top dressing and the "leafy removal" treatment, the number of leaf surface bulbs increased by 4-5 times and the weight of leaf surface bulbs increased by 2-3 times.
TABLE 4 influence of different growth regulators on the growth potential of amorphophallus bulbifer plants
As can be seen from Table 4, the difference of the different growth regulators on the growth of the amorphophallus bulbifer plants is significant, and compared with the comparison documents 1-3, the 18% chlocholene naphthalene acetic acid used in example 1 of the present invention has the best effect in controlling the plant height, increasing the petiole diameter and increasing the bulb expansion.
