With the advancement of science and technology, human beings are more and more accurate in predicting weather development. With a little click on the Internet, you can check the weather conditions within half a month. Seeing the weather forecast is the basic skill of the vegetable farmers. Anyone will look at it and adjust the vegetable management according to the weather forecast. But not everyone can use the weather forecast.
Facility vegetable production has already stepped out of the stage of “depending on the weather†and has become more and more resistant to bad weather. However, the impact of the weather on the growth of vegetables is all-round, and the impact will only weaken, but it will not disappear.
In recent years, the area of ​​greenhouse vegetables has become larger and larger, and the price of vegetables is not optimistic. Especially when the weather is smooth, the level of cultivation of vegetable farmers can obtain similar yields. Only in bad weather will there be a very significant difference, and the gap between production and efficiency is at this stage. For example, in early August, the price of loofah was still more than 5 yuan per catty. By the end of August, the price of loofah fell to less than 1 yuan, and the price was different.
How to increase the production of vegetables in bad weather is the most concerned issue for vegetable farmers. It depends on whether the farmers will use the weather forecast. Pests and diseases are the primary problem affecting yield and quality
Weather forecasts can be divided into medium and long-term weather forecasts and short-term weather forecasts by time. Needless to say, the short-term weather forecast can be inquired at any time. Farmers can arrange farm operations according to this. Watering, spraying and disease prevention should be prepared according to the weather forecast. In case of heavy rain, strong wind, cold wave and strong cold air activity, snow disaster, continuous Yin When the weather is bad, it is necessary to prepare in advance to prevent large losses caused by bad weather.
Here, we focus on the medium and long-term weather forecast, which is the annual, quarterly, and monthly weather trend forecast. For example, at the beginning of this year, meteorologists predicted that there was more rainfall in the northern region. As a result, the rains in the flood season were frequent in July and August, and the rainfall significantly exceeded. In the same period of last year, there was even a cloudy weather.
Long-term weather forecasts are important, but vegetable farmers are mostly lacking in understanding. Knowing the weather forecast for the growing season of the sorghum vegetables, the vegetable farmers can predict the growth of the vegetables and the occurrence of pests and diseases, and prevent them in advance. If there are many sunny days, the disease will be less, the vegetables will grow faster, the pesticides will be used less, and the fertilizers will be used more. On the rainy days, the diseases will be more, the vegetables will grow slowly, the medicines will be used more, and the amount of fertilizer will be greatly reduced.
Understand the long-term local weather forecast, but also pay attention to the long-term forecast of other main vegetable producing areas. For example, there are more rainfall in the north this year, more rainfall in the south, which is extremely unfavorable for vegetable production. The output of southern vegetables is obviously declining, so it needs to be transported from the north, vegetable prices. It will be better. Concerned about the long-term weather forecast of various places, vegetable farmers can make more accurate judgments on the market and subsequent growth of the vegetable market, adjust the mouthwash, and prepare for the highest efficiency.
