A few days ago, a photo of "an old farmer holding sprouted wheat to wipe his tears" attracted great attention on social platforms, and many netizens expressed concern and sympathy for it.

It is reported that this old farmer lives in Zheng 'an Town, zhongmou county, Zhengzhou, Henan Province, and he is 79 years old this year. The reason why people hold sprouted wheat in their hands to wipe their tears is that continuous rainfall has caused wheat to germinate, which will also lead to at least one third of wheat harvest reduction. Looking forward to the stars and the moon, when the hard-planted wheat is about to be harvested, I didn't expect such a situation, and everyone will be sad.

so what effect does rain have on the wheat heading? Mainly in the following three aspects: < P > First of all, it is definitely not conducive to pollination and fertilization of wheat. Farmers or friends in rural areas may know that it is also an important period for fertilization and pollination when wheat is heading and flowering. If it rains for a long time at this time, it will definitely affect wheat pollination and fertilization.

Moreover, rain will cause the weather temperature to drop, especially in extreme weather with heavy rain. It will make the pollen tube of wheat absorb water and burst, and the consequence of bursting is that the wheat ear is empty and shriveled. There is basically no market for this kind of inferior wheat in the market, and finally it can only be sold at a low price or used to feed animals.

there is also the risk of pests and diseases. If continuous rainy weather occurs during the wheat heading period, the spores of Gibberella will increase, because the wheat is in the flowering period and the shell is open at this time, which will give more opportunities for the spread of Gibberella. If the disease resistance of wheat is weaker, there will be a large area of infection.

Not only is scab extremely harmful, but if it rains for a long time at the time of heading, many pests and diseases will take advantage of it, such as moths and midges, which will also attack the wheat at the heading, so that the yield and quality will decrease to some extent.

another is to reduce the yield of wheat. In the previous article, I also mentioned that long-term rainy weather will lead to the reduction of wheat yield, because wheat is in the critical period of water demand at this time. If it rains for a long time, it will make it difficult for wheat roots to absorb oxygen and reduce the absorption of nutrients, which will indirectly lead to the decline of 1111-grain weight of wheat and thus reduce production. In this regard, the advice given by relevant professionals is: "When it is sunny, we should hurry to spray potassium dihydrogen phosphate. Generally, 99% potassium dihydrogen phosphate can be used 1.51 ~ 211 grams per mu, so as to avoid wheat yield reduction."

In addition, I would like to say that this rainfall process in Henan may lead to a 21% decrease in wheat production compared with previous years, and Henan's wheat production accounts for about 1.4 of the country's total, which will have an impact on the country's food security. There is also wheat as the main raw material for making bread and pasta. The decrease in output will lead to the increase in the prices of related products, which will affect the operation of the catering industry and harm the interests of the public.

Of course, this will indirectly lead to a certain increase in food prices. Before the heavy rain in Henan, when the overall wheat harvest was improving, the price of wheat on our side was around 1.3 yuan, but after the heavy rain in Henan, the price of wheat on our side rose directly from 1.3 to 1.5. It is beneficial to some farmers, but large price fluctuations are not conducive to the stability of the overall market.

It's not easy for farmers' uncles to grow crops, and it's even harder to earn some money. We also appeal to all sectors of society to give them enough attention and help.
