The wintering of rapeseed is heavy in the anti-freezing of strong seedlings?
The overwintering of rapeseed is important in anti-freezing of strong seedlings: Because of seedlings and fertilizers: rapeseed seedlings are very important for improving the quality of the seedlings and enhancing the ability to resist freezing. When the rapeseed is transplanted, the base fertilizer and the growing land can be used without any application. The growth is stable and less applied, but there is no adequate application for late planting and late-fertilization, and the current weak growth of weak seedlings and dead seedlings (only about 3 leaves, And the rapeseed field with stems and leaves, or uneven growth, should be applied as soon as possible. Fertilization is mainly based on organic fertilizer, and the plants with thin plants can increase the application of urea by 5 to 10 kg per mu to promote the transformation of the seedlings and strive for the wintering of the seedlings. Clearing the ditch: Waterlogging is an important obstacle to the high yield of rapeseed. For undigging fields, it is necessary to seize the favorable opportunity to open up the inner and outer ditch of the field, improve the ability of drainage and sedimentation, avoid the freezing and thawing alternation, and increase the freezing damage. It is necessary to deepen and unblock the unsupported fields, especially to open the horizontal and vertical ditch, connect the ditch head, keep the ditch unblocked, ensure the drainage is smooth, and the rain stops the field to prevent serious rain and rain in winter and spring. Water stains. When ditching and clearing the ditch, the ditch should be evenly covered in the roots of the rapeseed. In particular, the roots and necks of the "high-legged seedlings" should be buried in the soil to avoid seedlings and seedlings. In addition to the warming up: to the grass damage to the standard field, to seize the favorable opportunity of warm and warm, select the drug as soon as possible. Generally, grasses with weeds of more than 50 plants per square foot and broadleaf weeds of more than 10 plants per square foot must be removed. Master the daily average temperature above 5 °C to improve the elimination effect and avoid phytotoxicity. Rape field grass weeds can be selected with high-efficiency flupirtine or flupirin and other broad-leaved weeds, such as swine fever, bovine bristles, etc., can be used for herbicide control, single and dicotyledon weeds. Mixed fields can be mixed with the above drugs or selected with their compounding agents, or combined with winter and spring ploughing. Covering anti-freeze: The sorghum transplanting rapeseed should do a good job of loosening the roots of winter and spring, and keeping the roots warm and antifreeze. Straw mulching is used to combine straw returning with winter cover of rapeseed field, generally covering 150-200 kg of straw per acre to enhance the cold tolerance of rapeseed. In the 3-leaf stage, the paeonia seedlings that have not been used for paclobutrazol control and early sowing, should be warmed up before the winter, with 15% paclobutrazol WP 60-70 g and 30-50 kg spray. , greening, antifreeze effect.
