The application of paclobutrazol in the 3 to 5 leaf stage of direct seed oil rape can control the height of seedlings, promote the thickening of root neck, cultivate strong seedlings, and increase yield. You can use 15% paclobutrazol wettable powder per acre 40 to 50 grams of water and 50 kg of spray. High fertility, early sowing, high density of stubble, easy to form a "high-till seedlings" of the field, with 15% paclobutrazol wettable powder per acre 50 grams is appropriate. For a general level of field, use 15% paclobutrazol wettable powder 40 grams per acre.
The long residual period of paclobutrazol, and the secondary controlled phenomenon of crop growth occur frequently, and it is not appropriate to repeatedly use paclobutrazol for large areas on a regular basis. Uniconazole and paclobutrazol belonged to the same triazole compound, and its activity was 6 to 10 times that of paclobutrazol, and the residual soil was less. The secondary control length of the post-plant was significantly lower than that of paclobutrazol. Live rape 3 to 5 leaf stage, you can use 5% Uniconazole wettable powder 40 ~ 60 grams of water 30 kg spray, control on the promotion, control prosperous.
Rape seedlings without chemically controlled plots can be used at the end of November and early December of rapeseed with 15% paclobutrazol wettable powder per acre, 40-50 g water, 50 kg water per acre, or 5% uniconazole WP per acre. 40-60 grams of water 30 kg spray, promote plant dwarfing and improve the ability of antifreeze. Large and powerful seedlings are sprayed, and small and weak seedlings are sprayed or not sprayed. They control strong growth and keep the seedlings safe for winter.
In addition, potassium is ionized in the plant body. Potassium fertilizer can increase the cell fluid concentration of the crop, lower the freezing point, enhance the antifreeze ability, and be relatively light at the same low temperature. Potassium fertilizer production on the production is generally low, in the current basis per kilogram of potassium oxide increased 6 to 8 kg, sub-basic Miaofei, Feifei twice increase, but also conducive to defense against rape damage.
Greenhouse Seedling Bed
A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
