On the Grain Rain solar term, is it better for farmers to have rain or sunny weather? Why?

Grain Rain - Rain produces hundreds of grains. After the solar term, farmers have to enter a busy period. Related agricultural operations include sowing and transplanting seedlings, planting melons and beans, controlling diseases and pests, etc.

Grain Rain is one of the twenty-four solar terms. This year it falls on April 20. In the traditional sense, it presupposes the complete end of the cold wave, and there will be no more days of extremely low temperatures.

So, the continuous rainy weather during the Grain Rain solar term is both a good thing and a bad thing for farmers. Different crops have different growth conditions and encounter different pests and diseases in different phenological stages, so they must be treated separately.

For crops growing normally in the field, continuous rainy weather is not conducive to crop growth, and will bring about the occurrence of diseases such as scab, downy mildew, leaf blight and vine blight. Seriously endangering the safety of crops; however, for transplanted crops, continuous rainy weather is beneficial, as it can improve the survival rate of crops and quickly take root.

By listing common crops below, we can clearly distinguish the impact of Grain Rain. 01. Wheat

Grain Rain means sunny and good weather for wheat farmers in Henan. At this time, the wheat has just entered the flowering stage. After the chaff opens, pathogenic bacteria in the air will enter the chaff together with the rain, causing the occurrence of scab.

Once the chaff is closed, even if sprayed, it is difficult for the fungicide to enter the interior of the chaff to kill the germs.

However, for farmers growing wheat in Hebei and Shandong, Guyu is a good thing. The wheat ears in these two provinces have not yet emerged, and there is still some time before the flowering period. Naturally, there is no need to worry about the occurrence of scab. Enough rain can promote the growth of wheat, and there is no need to worry about drought. 02. Chili pepper

Grain Rain is a good rain for farmers who grow chili peppers. The peppers are about to enter the transplanting period, and they need sufficient moisture in the field to promote the seedlings to take root. The rain in the past few days can provide enough soil moisture to allow the pepper seedlings to take root quickly.

Not only that, after the Grain Rain, a large number of weeds will be unearthed. Farmers can spray herbicides according to their actual conditions and use herbicides when the weeds are young. The weeding effect is higher than that of later weeding. . 03. Tobacco Leaves

Grain Rain is a rare good thing for farmers who grow tobacco leaves. Similar to transplanting peppers, sufficient rain can provide enough moisture for the slow seedlings of tobacco. Without this rain, farmers would still have to water the fields themselves.

In this way, Grain Rain allows farmers to save irrigation costs. Isn’t it a good thing? 04. Peanuts

Grain Rain is a good thing for peanut farmers. Spring peanuts are basically sown in mid-to-late April. Sufficient moisture is needed for germination and seedling emergence. This rainwater falling into the ground can alleviate the drought and provide enough moisture for the peanuts to break through the ground.

If the moisture is insufficient after sowing peanuts, farmers need to spray a shallow layer of water on the soil surface to increase the germination rate of peanuts.

However, if the Grain Rain weather is accompanied by a cold wave, it will be a fatal disaster for the newly sown peanuts, which will cause the seeds to become sown and rotten, causing the peanuts to fail to germinate normally.

Not only that, with the rain of Guyu, many farmers will sow vegetable seeds (beans, fennel, coriander and peas). It only takes about 3 to 5 days for everything to be normal. Once they sprout, there will be no delay in eating fresh vegetables in the summer.

Our country has a vast territory, and there are many types of crops in the growth period during the Grain Rain solar term. I have listed only a few of them, and their effects are completely different, so we cannot simply judge whether rainy days or sunny days are better.
