Will continuous rainy weather affect wheat yield? Can topdressing be done in rainy days?

A small amount of urea can be used to supplement the fertilizer-deficient land, but it can be adapted to local conditions to prevent greed and yield reduction. But it's better than no rain. The biggest difficulty in farming now is drought and no rain. If the water conservancy can't keep up, the wheat yield will definitely be bad. This is a critical period when fertilizer and water are needed. This spring rain is perfect. Good rain knows the season! It also provides nutrient solution for wheat on the hillside where irrigation is inconvenient. In short, it is very beneficial for wheat growth to rain now!

Rapeseed needs a lot of water and fertilizer at the end of flowering and granulation. But in this season, water is a fatal disease and reduced production. Spring rain is as expensive as oil, and continuous rain at this time is most beneficial to wheat production. Spray once every 7 days to ensure prevention and control. Within the range of 1, do not use pesticides in case of windy weather or rain. Too much rain will collapse, which is not conducive to the development of roots, and there will be rotten roots, which can not provide nutrients well.

It is beneficial to increase the segregation of wheat in dry land, alleviate drought and topdressing. For well-isolated irrigated land and fertile wheat, the climate is abnormal, and cold air does not play by common sense. Anyway, the rain and snow in spring are gifts for farmers, and the southern part is mainly rice. The high humidity will cause the high incidence of rice virus, including vegetables. I don't know, am I right? Shrimp seedlings propagated in autumn are sold in shrimp paddy field in early spring, and the superposition of spring seedlings and autumn seedlings will produce uncertainty.

Slow growth or even stop growth, so that seeds rot in the soil, resulting in uneven germination, secondary sowing, increasing the burden on farmers; But I don't have a very professional investigation on whether this will affect crops, but I personally feel that this will have a big impact on crops. Then the situation of late spring cold also has great decisive factors for the completion of agriculture, such as tillage, sowing, germination and growth cycle. Any object has its own law of motion, but it is beyond people's vision. Yes, rape has been growing well for a long time, and wheat has also been affected. It has been raining continuously, and about 30% of the output has been lost. Alas, farmers are suffering!
