The 79-year-old Henan farmer wiped his tears with the sprouted wheat in his hand. What effect does rain have on sprouted wheat?

A few days ago, a photo of "an old farmer holding sprouted wheat to wipe his tears" caused great concern 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. People hold the germinated wheat in their hands to wipe their tears, because continuous rainfall has caused wheat germination, which will also lead to at least one-third of wheat production reduction. Looking forward to the stars and the moon, the hard-planted wheat is about to be harvested. I didn't expect this to happen, and everyone will be sad.

So what effect does rain have on the sprouted wheat? Mainly in the following three aspects:

First of all, it is definitely not conducive to wheat pollination and fertilization. Farmers or friends in rural areas may know that wheat heading and flowering is also an important period for fertilization and pollination. 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 and 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. This kind of inferior wheat basically has no market 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 there is continuous rainy weather at the heading stage of wheat, the spores of Gibberella will increase, because the wheat is in flowering stage and the shell is opened, which gives more opportunities for the spread of Gibberella. If the disease resistance of wheat is weak, there will be a large area of infection.

Gibberella is not only extremely harmful, but also if it rains for a long time at heading, many pests and diseases will take advantage of it, such as moths and midges, which will also damage wheat at the early heading stage and reduce the yield and quality to some extent.

The other is to reduce the yield of wheat. I also mentioned in the previous article that long-term rainy weather will lead to wheat yield reduction, 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, reduce the absorption of nutrients, and indirectly lead to the decline of wheat 1000-grain weight, thus reducing production. In this regard, the advice given by relevant professionals is: "When it is sunny, it is necessary to spray potassium dihydrogen phosphate quickly. Generally, 150 ~ 200 grams of 99% potassium dihydrogen phosphate can be used per mu to avoid wheat yield reduction. "

In addition, I would also like to say that this rainfall process in Henan may lead to a 20% reduction in wheat production compared with previous years, and the wheat production in Henan accounts for about 1/4 of the whole country, which will have an impact on national food security. And wheat is 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 public interest.

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

It is not easy for farmers to grow crops, and it is even harder to earn some money. I also call on all sectors of society to give enough attention and help.
