Pay attention to boron supplement in rapeseed

1. Early application of Spring Fertilizer: In the early spring, topdressing can remedy the inadequacy of winter rapeseed growth and promote more branches and early buds. In particular, the shortage of basal fertilizer and the failure to apply wax fertilizer to rapeseeds are the key to seizing high yields in the early spring. Generally 5-7 kg of urea or 10-15 kg of ammonium bicarbonate.

2, clever application of fertilizer: Rape buds fertilization period should be treated according to rape growth and appearance. For those fields with weak seedlings and poor growing conditions, it is necessary to reapply early, that is, when the height of axillary is about 50 centimeters, mu Shi excrete 15-20 urine, add 5 kg of urea or 45% compound fertilizer 10-15 kg; Growing fields with strong green leaves and dark green leaves must be delayed or less applied.

3, spraying boron on the leaf: rape is very sensitive to boron, and it needs a large amount. In winter and spring, most of China’s winter rapeseeds suffered severe and continuous drought, which had a major impact on the normal growth and development of rapeseed. Because of the continuous drought, the effectiveness of "boron" in soil is greatly reduced, and crop roots cannot be absorbed. As a result, rapeseed plants are deficient in boron, and flowering is not real, resulting in severe reduction in yield. Therefore, special attention should be paid to the application of boron fertilizer to drought-bearing rape. Even if rapeseed fields with boron fertilizers have been applied at the time of sowing or transplanting, foliar spraying of boron is still required during flowering.

Vaccine For Prevention Of Rabies

Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals
