If the wheat is harvested late, will the yield be reduced? Why?

Wheat harvesting is particular, the old saying often "nine ripe, ten harvest, ten ripe, one lost", or "nine percent of the harvest to protect ten percent, ten percent of the harvest lost one percent". They are all saying that the wheat harvest should neither be too early nor too late. There are two processes for wheat to reach maturity, first the wax maturity stage and then the full maturity stage.

At the wax maturity stage, the 1000-grain weight of wheat reaches the maximum, which means that the yield of wheat reaches the maximum value of the whole maturity period. However, if the wax maturity period is exceeded, the specific situation is that the wheat is only eight ripe, both in the past and now. In the past, manual harvesting required baling, and overripe wheat was easy to cause ear loss and threshing, and it was impossible to twist the waist with wheat strips (for baling wheat), so it was indeed too troublesome to harvest at this time, and the loss was not small.

<> fact, late wheat harvest will indeed reduce the yield, and there are two main reasons for the yield reduction, one is that the weight of the wheat grains becomes lighter, and the other is that the wheat grains will fall off if they are too ripe. As for judging the timing of wheat harvesting, an important reference is the weather conditions, if the weather is fine and there is no rain in the next week, you can properly let the wheat dry on the ears of wheat and then harvest, at this time the state should be gentle on the ears of wheat, and the wheat grains will be easy to detach and chew. Basically, you can cut it when it's almost dry, and it's easy to drop grain and reduce yield if it's too long, but if the weather is bad, you can cut it a day or two in advance, and the main reason why you need to dry it at home is that growing grain is not profitable, and even losing money.

The peasants were careful to plant less, to ensure food rations, and the rest of the time, to work to earn money. With the passage of time, the old peasants will grow old, the price of grain will not increase, and more and more land will be discarded.

Because some farmers have chosen wheat varieties with poor resistance to low temperatures, this year's main wheat producing areas in China have encountered low temperatures that have never been seen for decades, and the reason for freezing is the main reason for wheat to suffer from frost damage. The North China Plain is an important wheat producing area in China, and Henan is a province dominated by agricultural production and a major grain-producing province in our country. Due to the lack of groundwater resources in Hebei, the state has controlled the sown area of wheat, and the output has been reduced a lot.

Late wheat harvesting reduces yields. After the wheat maturity stage, the nutrients from the wheat grains will flow back to the straw, resulting in a decrease in grain weight and a yield of 30 to 50 kg per mu.

Yes, because if the wheat is harvested very late, it will cause a waste of resources and lead to a decrease in yield.

If the wheat is harvested late, the yield will indeed be reduced, because this is the time when the weight of the wheat becomes lighter, and the wheat is harvested late, and it will fall off if it is too ripe, so it will be wasted.

Don't think too much, wheat has to grow naturally to be fragrant, it is also a summer cropIt is impossible to make it precocious。Instead of trying to do the wrong thing, it is better to take good care of the wheat so that the yield will increase.

01. Reasonable fertilization makes wheat grow better and yield higher. First of all, there is no way to make wheat mature early, but you canProper fertilization, let the wheat grow better, and the final yield will not disappoint you. However, it is necessary to implement balanced fertilization according to the soil fertility status of the region, combined with the law of fertilizer demand for late-sown wheat, such as the combination of organic fertilizer and inorganic fertilizer, or the four supporting facilities of nitrogen, phosphorus, potassium and micro fertilizer.

In addition, late-sown wheat should be selected to be resistant to late sowing, early maturity, and good yield. When fertilizing, 60 kg of ammonium carbonate, 55 kg of superphosphate, 15 kg of potassium chloride, and 1 kg of zinc fertilizer should be applied per mu. At the same time, actively promote the application of chemical fertilizer deep application technology to improve the utilization rate of chemical fertilizer.

02. Reasonable spraying to control pests and diseases and improve yield. In addition to doing a good job of reasonable fertilization, it is also possibleSpraying pests and diseases, can be added to the wheat field into the potassium dihydrogen phosphate, brassin, foliar fertilizer containing a variety of trace elements, sprayed once every seven to ten days, sprayed three times, sprayed per mu two sprayers 60 kg of water. This method is good for wheat filling, and it can also resist dry and hot winds, allowing the wheat to ripen a week earlier.

However, it should be reminded that wheat cannot be sprayed with ethephon, and ethylene can only be used on cotton and fruit treesCooked。Lest the yield of wheat not increase, but decrease the yield of wheat, then the gains outweigh the losses, and there is no need to do such stupid things.

All in all, the early maturity of wheat is determined by the variety of wheat and the weather of the region, and the wheat in China is generally matured from south to north. For example, Henan Province, the main wheat producing area, began to mature from Xinyang and Nanyang in the southernmost part of Henan and slowly extended to the northern region of HenanIt doesn't have to be high.

Some farmers spray the concentration of "potassium sulfate" in the wheat filling stage, and use 3 ml - 10 ml of 40% ethephon preparation per mu at the wheat rejuvenation stage, because the use of these fertilizers can enhance the lodging resistance and have a certain promotion effect on early maturity in the later stage.

You can add a lot of fertilizer to the wheat after the rain, so that the wheat can ripen quickly, and then speed up the process and increase the light time, so that the yield can be high and not reduced.

Farmers generally add some fertilizers or ripening agents to the wheat, which can make the wheat mature quickly and early, and the yield will not be reduced.

Be sure to pay attention to the temperature, pay attention to the use of fertilizer, so that you can do it well, you must pay attention to the choice of varieties, you can choose some early-maturing varieties, which will not reduce the yield.

Wheat can be sown in a month and a half from the white dew solar term in autumn to the frost solar term, and it can even be planted in winter"Cover in the soil, and the next year in the early spring of seven or nine can also be planted"However, whenever the wheat is planted, even if there is a difference of fifty days between sowing, it will ripen in a uniform fixed time, and it will not exceed four or five days before and after. "Nine ripe, ten harvest, ten ripe, lose one", meaning that wheat cannot wait for ten to mature before harvesting. If the wheat does not lodging, the weather is sunny and there is no rain for half a month, it is okay to postpone the wheat harvest by 2-5 days.

But the wheat lodging is already ten ripe, and the weather is cloudy and rainy, so it can't be postponed, because the wheat lodging is easy to germinate, and there will be no harvest.

It means that if the solar term of the mango seed is in the fourth month of the lunar calendar, it means that the wheat has just begun to be harvested, and it is assumed that if the solar term of the mango seed is in the fifth month of the lunar calendar, the wheat harvest has ended. This year, the solar term of mango seeds is on the 25th day of the fourth month of the lunar calendar, and according to the regular time, wheat should start to enter the harvest stage around the 25th day of the fourth month of the lunar calendar. It is time to harvest the wheat, and the wheat mixed with soil and clay can also be harvested from June 2 to 5, but some plots have lodging due to the wind and rain weather in the previous few days, and the lodging wheat is some blue, and it will be harvested by June at the latest.

Due to the limited photosynthesis of leaves, there will be grains or shells without seeds at the upper and lower ends of the panicle, and the grain weight in the middle will also decrease significantly, and the yield of this kind of wheat field will be reduced by more than 300 catties. On April 23, the wheat had just entered the flowering stage, and lodging had the greatest impact on the yield at this time. Generally more than 400 catties or more.

The harvest took place two or three days later than in a normal year. It is expected that the harvest time of Zhoukou wheat will be around June 5, and this year's overall wheat growth is good, with full grains, and individual lodging or diseased wheat fields. The reduction in production is more serious.

I hope that friends who work outside will pay attention to the wheat harvest time at home and return to their hometowns in time to harvest wheat and plant autumn.

Wheat in the north is generally harvested around July, when the wheat is fully ripe and can be harvested on a sunny day.

The harvest is carried out almost in June, and it mainly depends on the growth of the wheat, which is relatively good, and it can also be harvested in advance.

Harvest on sunny days, as this is when the wheat is quickly dried.

Summary. 3.Compared with mature wheat, there are more growth cycles, and due to climate reasons in the process of wheat ripening, natural disasters are prone to occur, such as strong winds, heavy rain, dryness, hail and other climatic influences, so harvesting immature wheat also safely avoids the impact of natural disasters.

Wait a minute. Wheat is harvested before it is ripe, this is because 1Some people use unripe wheat as green storage, that is, animal-like bifed open and closed feed, which is about 1,500 yuan per mu, which may have more income than low-priced mature wheat.

2.Immature wheat is used as feed and is easy to process, but compared to mature wheat, there is less process of cutting the wheat and drying it. At present, the cost of farming is high.

33.Compared with mature wheat, there are more growth cycles, and in the process of wheat maturity, due to climate reasons, it is easy to have natural socks and reeds, such as the climate effects of Dalu good training, heavy rain, demolition and hail, so harvesting immature wheat also safely avoids the impact of natural disasters.

When I saw that the wheat was harvested before it was ripe, my first reaction was quite surprised, and then it was a pity. The surprise is that if it is not matured into wheat, it cannot be processed into flour and made into various staple foods such as noodles, cakes, cakes, etc. And harvesting before maturity is actually sold as grass as food for livestock, and a small part of the ** may be higher than wheat in the short term, driven by short-term interests, but definitely not a large-scale long-term crop planting.

1. The growth cycle of wheat.

To see whether the wheat is ripe, it also depends on the whole growth cycle of the wheat.

Wheat is divided into winter wheat and spring wheat, and this time it was winter wheat that was harvested. Planting was completed around the end of September to mid-October last year, and the harvest was around June this year.

The growth cycle of wheat is 12, namely, seedling, three-leaf, tillering, overwintering, regreening, rising, jointing, booting, heading, flowering, grain filling, and maturity. From the point of view of time, it is indeed a pity that the wheat harvest is in the middle of the flowering and grain filling period.

After all, the wheat fruit was about to be harvested, but it was harvested early. Hail.

2. The possibility of using immature wheat as feed for livestock.

As a gramineous wheat plant, wheat is also one of the three major cereals, but it can indeed be used as feed for livestock such as cattle and sheep before maturity, commonly known as green storage.

Affected by the economy and the epidemic, the transportation is not very convenient, it is difficult to achieve cross-regional purchase and mobilization of some green storage feed, and in the case of feed shortage in some farms, green plants such as grass from the local will be considered.

There may be an emergency ** to buy, after all, wheat is also a high cost at this time.

3. Other possibilities for unripe wheat to be harvested.

Most of the wheat is grown in the suburbs or in rural areas. However, there are also cases of urban expansion, road construction, and other projects, and the need to occupy wheat fields leads to early harvesting of wheat.

For example, the city is expanding, and the remaining growth cycle of wheat cannot catch up with the construction period. If there is a road that needs to be built immediately, the wheat fields are just within the planned area of the road. Or the wheat is harvested early because there are other resources in the field where the wheat needs to be mined, or other projects are about to start.

4. Why is the harvest of unripe wheat so interesting?

Sometimes I feel that the land and the peasants are far away from me, but in fact, every day of life is inseparable from it, because it is related to your three meals a day and your three hundred and sixty-five days. So when you see the unripe wheat being harvested, it's really heart-wrenching and anxious.

In addition, whether it is the epidemic or other local conflicts, food security is the most stable.

The people live on food. The more ordinary the food, the more basic the guarantee of life. Therefore, the wheat that is not yet ripe really cannot be cut any further, nor can it be harvested more. In ordinary times, you should also keep in mind that who knows that Chinese food is hard work.

Hello early preparation. Wheat is harvested before it is ripe.

It is to make green leaky feed.

Because there are no ripe green barley seedlings sold.

It's a little higher than selling ripe wheat**.

However, this kind of behavior has seriously affected the production of grain.

The relevant departments have stepped in to stop it.

Solutions are being sought.

No, we harvest all the wheat when it is ripe.

Wheat harvesting is particular, the old saying often says "nine perfect, ten percent harvest, ten perfect, one percent lost", in other words, "ninety percent of the harvest is guaranteed ten percent, ten percent of the harvest is lost". It's all about saying that the wheat harvest should not be too early or too late. Experienced farmers are able to manipulate the wheat harvest time, go to the wheat field a few times before the wheat harvest, rub the wheat ears with their hands to carefully check the wheat bran, or pinch the wheat grains with their fingernails, whether they can pinch the wheat bran, or only pinch out the nail marks to distinguish the ripeness.

There are two processes for wheat to mature, the first is the wax ripening period, and then the full ripening period. At the wax maturity stage, the emergence rate of wheat grains reaches the highest value, in other words, the total yield of wheat at this moment reaches the highest value of all ripeness. However, if the wheat is harvested after the wax maturity period and is not harvested until the wheat maturity stage, the grain emergence rate of the wheat will decline, and the yield of the harvest will of course be reduced compared to the harvest at the wax maturity stage.

In addition, when the wheat reaches the ripening stage, all the stems are withered, the volume of the grains becomes smaller, the moisture content decreases, and it shows a hard shape, which is not easy to crush when pressed with fingernails.

When wheat reaches the ripening stage, it can be divided into milk ripening stage, wax maturity stage and full maturity stage. The wax ripening period can be subdivided into three stages: the early wax ripening stage, the middle and late wax ripening stage and the late wax ripening stage. In that way, the best time to harvest wheat is at the later stage of wax ripening, and this can be distinguished in this way, that is, by analyzing the external appearance of the wheat.

At this time, all the wheat plants show pale yellow, the stems still maintain a certain degree of ductility, and the appearance and color of the seeds are the same as the characteristics of the original species.

The net weight of wheat bran becomes lighter, like planting vegetables, there will be a larger volume, this time belongs to the net weight of the larger, and once it is perfected again, the net weight of vegetables and fruits will become lighter and lighter. The same is true for wheat, which will have the best ripeness, at this time the wheat bran is the most round, the more net weight, the more wheat can be harvested at this time. As for how to determine the time of harvesting, if the temperature has been good, eat a bite of wheat immediately, it feels very simple and the particles are already mellow and can be harvested, which is also the best situation for harvesting.
