Experimental example
Selection of planting Density
(1) Plant spacing is unchanged, and row spacing is changed
The oil peony is generally two kinds of peony with purple spot and Paeonia ostii. The mechanized planting adopts wide and narrow rows, wide-row mechanical channels and narrow-row planting belts. If the plant spacing is kept unchanged, a hand machine and a small machine are respectively used, and the single-row planting mode and the double-row planting mode are adopted for comparison, and as can be seen from tables 1-1 to 1-4, the double-row mode has the advantages of more seedlings per mu and higher yield.
TABLE 1-1 Paeonia ostii one-row planting Density and seedling quantity
Table 1-2 Paeonia ostii double row planting Density and seedling amount
TABLE 1-3 Single row planting Density and seedling quantity of Paeonia ostii
TABLE 1-4 double row planting Density and seedling quantity of Paeonia maculata
(2) The row spacing is unchanged, and the plant spacing is changed
The row spacing is kept unchanged, a hand machine and a small machine are respectively used, different plant spacing changes are adopted for comparison, and the tables 1-5 and 1-6 can find that smaller plant spacing can ensure that the seedling consumption per mu is more and the yield is higher.
TABLE 1-5 planting Density and seedling quantity of Paeonia maculata in wide and narrow rows at different plant spacing
Table 1-6 Paeonia ostii at different plant spacing planting densities and seedling amounts
Table 2 example 2 and comparative examples 1, 2 planting pattern number of seedlings that can be planted
Cultivation mode | Comparative example 1 | Comparative example 2 | Example 2 |
Plant spacing/m | 0.5 | 0.5 | 0.5 |
Line spacing/m | 0.8 | 1.2 | 1.2 |
Number of seedlings/plant | 1683 | 1122 | 1496 |
According to the description of table 2, in the mechanized planting mode of the embodiment 2 of the present invention, i.e. double-row planting, although the number of seedlings that can be planted is slightly reduced compared with the number of seedlings planted in a single row in the prior art, a mechanical channel is reserved to facilitate early sowing, middle-period field management, such as fertilization and pesticide spraying, and later harvesting can be combined with the machine, so that the working efficiency is greatly improved, the limitation of shortage of common labor force in rural areas is eliminated, and the yield and seed oil quality of peony seeds for oil can be remarkably improved by timing pesticide spraying and fertilizer application. Compared with the cultivation method in comparative example 2, the number of planted seedlings is obviously increased, land resources are more reasonably utilized, and meanwhile, the double-row cultivation mode can form a group effect, suppress or reduce overgrowth of weeds, indirectly save soil land loss and improve the yield of peony.
The 1496/1122-1=33.33% of the total plant peony seedlings can be planted from the standpoint of the total plant effect and the soil nutrition can be saved. The double-row cultivation and the planting mode of reserving the mechanical channel provided by the invention improve the yield by 33%.
The mechanized planting process adopts a mode of double rows and mechanical channels, so that higher yield can be ensured, and the later mechanized fertilization, mechanized pest control and mechanized seed picking can be ensured. The mechanical channel occupies planting land, the benefit balance points of the land used for the mechanical channel and the planting land are required to be grasped, a good planting mode is adopted, and the land utilization efficiency is improved as much as possible.
According to the embodiment, the mechanical planting method for the oil peonies is provided, the yield is increased by at least 21% by adopting the mechanical planting method, the survival rate of the peonies is improved according to local conditions, the peonies are mechanically planted and maintained and managed in the whole process, and the investment cost of manual labor is greatly reduced. The mechanical work efficiency is high, the mechanical planting cost per mu is about 40 yuan according to the comprehensive cost, and the manual planting cost per mu is about 70 yuan. Under the condition of less and less labor force, mechanical planting is adopted, and the cost can be saved by about 43 percent. And during harvesting, seeds can fall on the ground if the seed setting property of the oil peonies is not timely harvested, so that the oil peonies planted in a large area are negatively influenced.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
