Continued low temperature and rainy weather is not conducive to the growth and development of rapeseed. The agricultural department of Hunan Province recently introduced technical measures to guide farmers to grasp the late cultivation of rapeseed, reduce the adverse effects of low temperature and rainy weather, and seize the high yield and good harvest of rapeseed, while at the same time fighting for the early rice production.

Since the beginning of this year, Hunan Province has suffered from long-term low-temperature and rainy weather, which has led to weak growth and slow growth of rapeseed in some areas. According to the forecast of the meteorological department, from March to April this year, the number of low temperature and rainy days will still be more than normal.
Technical measures introduced by the agricultural sector include:
Strengthen the clearing of the ditch. It is necessary to clean up the "three ditch" (cavity, lumbar ditch and furrow) of the rapeseed field in time. For the shallower and poorly drained fields of the “three ditchâ€, it is necessary to increase the depth of the “three ditch†to ensure the smooth flow of the ditch, prevent water accumulation in the field, reduce the humidity in the field, improve the permeability of the soil, and reduce the water stain on the rapeseed. harm.
Pu Shi foliar fertilizer. In order to promote the growth and development of plants, increase the weight of 1000-grain, it is necessary to apply fertilized fertilizer such as boron fertilizer and potassium dihydrogen phosphate in the rapeseed to the initial flowering stage. For rapeseed that has been shown to be deficient in boron, it is necessary to increase the amount of boron fertilizer and the number of sprays. It is not advisable to apply nitrogen fertilizer to the bottom of the fertilizer, the seedlings, and the seedlings, so as not to cause lodging and affect the yield of rapeseed.
Control pests and diseases. At present, we must focus on strengthening the prevention and control of diseases such as sclerotinia and aphids. Before the onset of Sclerotinia sclerotiorum, it is necessary to use carbendazim, thiophanate-methyl and mancozeb to prevent and cure Sclerotium disease. For the field where the mites are harmful, it is necessary to use the sputum and anti-Suiwei drugs for prevention and treatment.
Harvest at the right time. In the later stage of rapeseed growth, some old leaves and yellow leaves should be removed to increase the ventilation and light transmission of plants, and accelerate the development of plants. Using the characteristics of rapeseed with ripening, the three-cooked rapeseed can be cut down by the rapeseed about 5 days before the ripening, moved out of the field, let it be cooked and threshed, and the field is released for early rice production, which will win time for early rice production.
