Today is the beginning of the winter, the beginning, the beginning, also said that the winter began. Winter is the end of the meaning, there is the meaning of collecting crops after harvesting, and China has made Lidong the beginning of winter.

At present, rapeseed is in the stage of vigorous growth before winter. The transplanted rapeseed is in the 7-10 leaf stage, and the live rapeseed is in the 4-6 leaf stage. Due to the influence of the previous rainy weather, there are different problems in the field, mainly caused by waterlogging, pests, grasses and prosperous. Today we will systematically analyze how to solve these problems if they occur.

Water stain

Because of the rainy and poor furrows in the field, most of the fields have different stains and damages, which are characterized by purple leaves, poor root growth and browning, slow growth or stagnation. In the field management, we will continue to do a good job in clearing the ditch. On the one hand, the field of heavy water damage is sprayed with high-quality foliar fertilizer (Huilongbao, Meijiafu, American Star, Cuilanchun, etc.) plus plant growth regulator (Brassica lactone or Bishui), on the other hand Apply 10 kg of urea to the mu to promote the growth of rapeseed as soon as possible.

Wang Chang

Due to the high density of live rapeseed, coupled with abundant rain and moderate temperature, some fields have a tendency to grow or prosper. For the field with high density, it is necessary to timely release the seedlings. For the long field, the roots can be cultivated or rooted or chemically controlled. Paclobutrazol, uniconazole or calcium arsenate (high tube) can be used, which can control both the control and the antifreeze.

Pest

At present, rapeseed worms and mites are more common in rapeseed fields, and the jumping armor and diseases are lighter. Taking advantage of the current good weather, the field of pests is controlled once, especially the aphids not only affect the normal growth of the vegetable oil, but also cause the virus disease to occur after the year. The cabbage caterpillar can be controlled by sword or 9080 or well-being (controlling aphids when available). The aphids can be controlled by imidacloprid (Amerika) or pymetrozine (granule, peak, double electricity).

Grass damage

Gramineous weeds can be selected with high-efficiency flupirtine (high-efficiency grass) or ketene. Broad-leaved weeds can be treated with herbicide or clopyralid or its compounding agent. It is worth noting that the chlorfenapyr can not be applied after flower bud differentiation. With or without, the herbicide is applied after the 5 leaf stage, otherwise it will cause phytotoxicity.
