Can corn brassin spraying increase yield? On what basis?

1.The answer, of course, is to increase production.

2.However, there are prerequisites for corn to increase the yield of brassin, which is a plant growth regulator, which can regulate the distribution of crop nutrients, promote the pollination of crops, improve crop stress resistance and photosynthesis ability, but the premise is that crops can absorb enough nutrients, and only in the case of sufficient nutrients, brassinin can play a better role.

Corn spraying with brassinin can increase yield; Because brassinin also has the ability to promote root development, promote yield, improve the cold and drought resistance of crops, and have a certain photosynthesis, it can also increase the green content of plants, so it can increase yield.

Corn spraying brassinin can increase yield; Because spraying brassin, corn can reduce the baldness at the top of corn, increase the number of grains and the total amount of corn, and also increase the total weight of corn, so as to achieve the purpose of increasing yield.

Speaking of brassin, I believe many rural friends should know that brassinin is a regulator to promote the growth of crops, and the main purpose of spraying brassinin on corn is to supplement the corresponding nutrients to the nutrient-deficient parts of corn, promote corn pollination, and can improve the photosynthesis of corn. In this way, the growth of corn can be promoted, so spraying brassin, of course, can increase yield, but spraying brassin, corn also has certain prerequisites.

In the process of corn growth, the premise of spraying brassinin on corn is that corn can absorb sufficient nutrients, and corn must spray some brassins in the case of sufficient nutrients to better improve the quality of corn and achieve the effect of increasing yield. For example, when corn is growing and in the flowering stage, the corn kernel needs to accumulate a lot of nutrients. At this time, brassinin plays a great role, which can regulate the nutrients absorbed by corn through its root system and photosynthesis, and transport them to the corn grains, so as to promote the accumulation of a lot of nutrients in the corn grains, so that the purpose of increasing yield can be achieved.

Therefore, in the process of corn growth, proper spraying of brassinin is very helpful to increase corn yield, but everything is not only good, of course, there are some disadvantages. If we do not spray brassinin properly during the growth period of corn, it will not help the growth of corn in any way. Therefore, when we spray brassin, we must grasp the time of topdressing, the peak period when corn needs a lot of fertilizer is in the period from its big bell mouth to heading, and corn needs a lot of nutrients and water at this time.

Therefore, the best time to spray brassinin on corn is within a week or so before the large flare of corn, and we should also pay attention to the amount when spraying. Although brassinin has a good effect on increasing corn yield, we can not use it unscrupulously, if the amount is used too much, it will also lead to the phenomenon of premature aging and yellow leaves in the late growth stage of corn.

Excessive use of brassinin will cause the plant to grow wildly, and the leaves do not grow fruits.

Too much brassinin in corn is not very harmful. Excessive use of brassinin will cause the plant to grow wildly, and the leaves do not grow fruits. Excessive application of brassinin may cause corn to grow. Excessive application of brassin in maize plants will grow too large and too dense, which will affect maize yield.

Corn seedlings can not be beaten with brassin, otherwise it is easy to cause weak corn seedlings. Brassin can be used when the corn plant grows 10-12 leaves, that is, in the corn flare stage and before the corn tasseling, brassinin can be used 10-20 ml each time, mixed with 50 kg of water for whole field spray.

Dangers of brassin

Excessive use of brassinin will make the plant grow wildly, and there will be a phenomenon of long leaves but no fruits, so it is necessary to use brassinin reasonably according to the requirements.

Corn seedlings can not be beaten with brassin, which is easy to cause weak seedlings. Brassin can be used when the corn plant has 10-12 leaves, i.e. before the corn trumpet stage and before the corn tasseling. When using brassin, we should pay attention to the dosage, not too much and not a small amount, if the dosage is too small, it will not have the desired effect, and the dosage is too large, which may lead to corn leaves without ears, ears without grains.

When spraying brassin, do not use with herbicides.

Plant hormone brassin, also known as brassin, its composition is sterololides, and the plant growth regulators with imitation brassin-like effect on the market are 14-hydroxybrassinsterol-epibrassinolide, 24-epibrassinolide, 28-epibrassinolide, 28-homobrassinolide, amine fresh ester and sodium trinitrate.

Corn spraying brassinin is to increase yield, and it should be about 200 300 catties per mu. When 10 12 leaves of corn, spray the whole field with 10 20ml of brassinolide and 50 kg of water. Brassin has a very obvious effect on maize, which can effectively accelerate the growth of maize and maize jointing, promote root development, reduce maize baldness rate, empty stem rate and empty grain rate, and increase maize maturity 100-grain weight.

This effect is really more, and it is a new type of hormone drug. Brassin is actually a new type of technology, and many people will choose to use it now, because one of the most obvious effects is that it can increase the efficiency of photosynthesis, which can make corn grow better, at least for the roots to become thicker, to make the flowers bloom better when flowering, and to make the fruit fuller when it bears fruit. <>

In the flowering period of brassinin can effectively promote the fertilization of pollen, pollen fertilization is good, then the next results will be better, this is an interlocking growth law, if the flowering period is not good, then the later stage can not be a good fruit.

The reason why corn needs to fight this brassinin is nothing more than to increase the ability of crops to resist cold and drought. Some people grow corn, but their plots are not well hydrated, so playing this brassin, you can make the crops more stable against drought and cold, so that there will be no yellowing or slow root growth. <>

No matter what crops are planted, this disease is susceptible, but if some brassinin is added when corn is planted, the occurrence of this disease can be well reduced. Diseases have always been a headache, but this medicine can reduce the disease, make the crop more resistant to disease, less prone to disease, and thus allow the crop to grow rapidly. <>

However, many people are now playing this hormone brassin, just to increase production. According to the research of relevant people, the injection of this drug can increase the yield by about 30% per mu. Because the lodging resistance will become stronger, the corn will grow faster, and the stalk will be thicker Generally speaking, it will be much thicker than the one that is not beaten, and the corn itself will grow well, then the result will be better.

Of course, it is essential to supplement the top dressing fertilizer here, and the fertilizer is supplemented well, and the absorption is better, so that you can get a greater harvest.

It is a hormone drug, because this can improve the ability of corn to resist cold, and it can also improve its growth rate, and it is not easy to wilt or yellow.

This is a hormone that can improve the quality of the crop and also add some nutrients that can make the plant healthier. This reduces pests and diseases and can also increase yields, which is good for corn.

Yes, in fact, the use of these chemical fertilizers for corn during this period can also make this corn grow better and have a higher yield.

Of course, you can, because they have a very high demand for the same amount during this period, and it can be a good supplement to ensure their production and growth.

Absolutely. These two fertilizers can make corn grow better, and can also increase the yield of corn and improve the lodging resistance of corn.

Of course, it is very good to use fertilizer at this time, and it will also make the corn grow very healthy, and the yield will be very high, and it is best to choose fertilizer around 10 am or after 3 pm.

Of course, the use of brassin and zinc fertilizer will make corn better at enhancing its fertility absorption, and it will also make its root system more developed.

Corn hits brassinin at 10 to 12 leaves. It can make corn jointing fast, thicken and widen the leaves. Improve the ability of corn to resist drought and waterlogging.

Anti-lodging. Improve the quality of corn and reduce the number of empty plants, bald tips, and seeds. Increase the weight of 1000 grains.

Thus increasing yields.

In the growth cycle, corn should be beaten once every 7 to 12 days, which is used to bloom in advance, prolong the flowering period, and improve the quality of the product.

After spraying, it must be able to increase the yield, basically the yield will increase by hundreds of catties, the first point should be sprayed at the beginning of the stage is really good, the second point is to spray again when the corn is halfway up, and the third point is to spray again when the corn is about to receive the fruit.

I think it's okay, and it's best to start spraying in the summer evening, because it's better to digest at this time. Let the corn grow better.
