Is it good to mix wheat varieties? What kind of wheat seed dressing is bad?

The phenomenon of mixed planting of wheat seeds has existed a long time ago, when people did not have the consciousness of good seeds, and when they sowed wheat, they would take some wheat from the grain hoard and plant it. But now, people have realized the importance of high-quality wheat varieties to increase yields, so there is no one who does not pay attention to wheat seeds, and no one will mix wheat seeds.

As for the question raised by the subject, whether the mixed planting of wheat seeds is good or not, there should be no question of whether it is good or not, but the question of whether it is feasible, in fact, the method of mixed planting of wheat seeds is an outdated old way of doing things. It can be seen from the following two aspects:

First, if you just eat it yourself, without considering the yield and purity of the variety, you can mix it. For example, we grow winter wheat here.

As long as the growth cycle of different wheat varieties is the same, they can be mixed and sown at the same time, and they can grow together to flowering and bearing fruit. Since wheat is self-pollinating, it will not have any effect on each other, but there may be uneven wheat straw in the field, which will not look good. The key point is that the mixed wheat varieties must have the same maturity period, if the maturity period is not synchronized, it will affect the harvest.

Of course, this may be the imagination of the subject, and now no one will mix different wheat varieties together for planting.

Second, under normal circumstances, in order to increase wheat yield, improve the purity of seeds, or prepare to sell wheat seeds, farmers must not mix different wheat varieties. The effect of increasing the yield of high-quality wheat varieties is obvious, after farmers buy high-quality wheat varieties, they will generally be planted for two or three consecutive years, and then the high-quality wheat varieties are relatively high, so farmers will not artificially carry out mixed planting. We can say that in the past twenty or thirty years, there has never been such a phenomenon of mixed planting of different varieties of wheat.

To sum up, the question raised by the subject is actually a wheat sowing method that has now been eliminated. In the past, when people did not have the awareness of improved varieties, farmers had mixed planting, that is to say, as long as the wheat growth cycle is the same, different wheat varieties can be mixed planting, and now people realize the importance of improved wheat varieties to increase yield, and have eliminated the old-fashioned planting methods in the past.

Not good, each variety of wheat has its own survival requirements, mixed planting is not easy to master, wheat mixed breeding may also cause cross-breeding, resulting in impure varieties, reduce yield and other problems.

The two kinds of mixed wheat are definitely not good, and different growth nodes will lead to uneven wheat growth areas, which is not conducive to wheat income generation.

I don't think it's good, because it will be very inconvenient when harvesting later, and the two flavors will mix together.

1: The more colorful the seed dressing, the better it is.

The color of the wheat seed dressing only provides a warning for everyone, in order to distinguish whether the seeds have been mixed with the seed coating agent to avoid being eaten by livestock by mistake.

2: The stronger the medicinal taste, the better the medicinal effect.

The stronger the medicinal smell of the seed dressing, the more toxic the pesticide ingredients added in it, if only the pesticide ingredients are used to control pests, it is far from enough.

Three: the larger the seed dressing, the more sufficient the amount of medicine in the bottle, the better the efficacy.

When choosing a commodity, many farmers often like to choose the one with a large amount at the same price, which feels like taking advantage;In fact, I don't think so, often the larger the amount, the lower the efficacy content of the previous foci, in the choice of seed dressing agent still need to look at the formula, we don't want to take advantage of the loss.

Four: the better the film-forming effect, the brighter the better.

In fact, this film-forming agent is a chemical substance, just in order to smoothly lower the seeds under mechanical sowing, that's all, in addition, the film-forming agent will actually affect the water permeability and breathability function of the seed, and the lower part of the low temperature will not promote the early germination of the seed, but will affect the normal germination of the seed.

You can use high-yield wheat seed dressing in all aspects, which can improve the emergence of wheat seeds, the growth of seedlings, improve seed vitality, improve seed germination rate, improve seedling potential, strengthen seedlings, and strengthen seedlingsIt can prevent and control the insect pests that often occur in the wheat seedling stage, underground pests: such as needleworms, mole crickets, grubs, ground tigers, etc.;Pests on the ground: aphids, planthoppers, etc.;Diseases:

Root rot, total erosion, sheath blight, smut, etc.;Promote wheat production.

Hello dear, I am honored to receive your question to keep you waiting, dear, in addition to the first test of the empty source of the wheat dressing agent, it is also advisable to use the special agent registered for wheat dressing. Different crops have different dosages of seed dressing. Cooladou Blind Seed Dressing is difenoconazole, fludioxonil and thiamethoxam suspension, which can well control aphids and underground pests and prevent fungal diseases in the early stage of wheat seed dressing, and can delay the damage of aphids in the later stage, and the damage of aphids is significantly reduced.

Dibendan, (3% difenoconazole), Gaoqiao (65% imidacloprid). Syngenta's latest wheat seed coating agent Coolas, the ternary compound effect is goodThank you for your trust, the above is my reply, I hope it can help you, I wish you a happy life and smooth work, if it is convenient, give a thumbs up, thank you.

It is good to choose the dosage form of seed coating.

1. At present, there are many dosage forms, but wheat dressing should first suspend the dosage form of seed coating.

2. Because the suspension seed coating can be better and uniformly adhered to the seed surface than other agents, and because of the different processing technology, the suspension seed coating usually contains warning colors.

3. It is not only convenient to judge whether the seeds and the agent are mixed evenly, but also to prevent poisoning caused by accidental ingestion, and can also avoid the impact of pesticide damage caused by uneven mixing.

1.Reducing the losses caused by wheat pests Wheat seed dressing generally contains insecticides, which can avoid underground pests and prevent the occurrence of above-ground pests in a large area, which plays a key role in wheat. 2.

Reduce the loss caused by wheat diseases Sheath blight, total erosion, root rot, straw powdery mildew, scattered smut and fishy smut and other diseases occur seriously, which can easily cause yield reduction or even extinction. Xiaoli mu wheat seed dressing is generally compounded with agent, from seed sowing to form a preventive measure, inhibit the infection of Qiliang fungus, reduce the occurrence of disease, so as to obtain the increase in yield. 3.

Robust plants, enhance stress resistance, increase yield Generally, in high-yield fields, the number of ears per mu should be 40-450,000 ears, the number of grains per spike should be 40-50, and the 1000-grain weight should be 40-45 grams. Wheat seed dressing before sowing can effectively regulate the growth of plants, ensure the robustness of plants, and lay the foundation for increasing yield. 4.

Prevention is greater than, early reduction of damage wheat sowing before seed dressing is mainly to play a preventive effect, if insect pests, diseases occur, and then use pesticides, this has caused part of the damage, so advocate wheat sowing before seed dressing, early reduction of damage.
