The Jilin Provincial Meteorological Observatory predicts that cold air will affect Jilin on the 27th, and temperatures will drop significantly on the 28th. On the 29th, the first frost will appear in most parts of the central and eastern parts of the country, and some areas in the eastern mountainous areas will have frost or frost on the growth of crops. Unfavorable, need to be prevented in advance.
At present, crops in Jilin Province are at the end of filling, and most of the counties (cities) in the central and western regions have entered maturity, and rice has entered maturity, and soybeans have matured or are close to maturity. On the 29th to 30th, the creams in the central and eastern regions will have little effect on the grain crops such as rice and corn that are already ripe, but they will have some impact on the crops that are still in the waxy and greedy land. Temporarily stop. Frost may appear in some parts of the eastern mountainous area, and the top leaves of the crop will die, affecting the maturity of the filling. For the open-air melons and vegetables, fruits and flue-cured tobacco, it will also have certain adverse effects.
Experts suggest that relevant departments and local peasant masses should carry out anti-frost work in time before the frost. For mature rice, it should be harvested in advance to prevent lodging after frost; for the corn field that is greedy, the weeds in the field should be removed in time, the ventilation and light transmission conditions of the farmland should be improved, the crop grouting should be promoted, or the topping and bottoming leaves should be promoted. Precocious measures. Vegetable fields, orchards, etc. take measures such as irrigation to prevent frost. If conditions permit, it is also possible to take measures such as covering and fumigation. For vegetables in the greenhouse, cold insulation measures should be applied to the greenhouse to protect the vegetables from low temperature.
