How long after wheat dressing is a good time to sow seeds? Will the germination rate be affected aft

Wheat seed dressing has outstanding control effect on the prevention of underground pests, especially wheat budworms, coupled with wheat total erosion, sheath blight and scab caused by the gradual increase in yield, the level of awareness of wheat seed dressing throughout the country is constantly improving. Wheat seed dressing can improve the germination of seeds, promote soil microorganisms, and have a robust function on wheat, and finally achieve the purpose of increasing yield. The purpose of wheat seed dressing is to be an insecticide, pesticide fungicide, conditioning agent or micro-fertilizer, the purpose of insecticides is to acetamiprid, thiamethoxam, high chlorine, etc., pesticide fungicides are tebuconazole, fludioxonil, difenoconazole, etc., <>

Conditioning agents such as micro-fertilizer or chlormequatin. Wheat seed dressing is generally based on the previous land disease situation to choose the appropriate seed dressing agent, when dressing the seeds, let the drug sufficiently adhere to the seeds, after mixing, wheat seeds are more sticky and wet, not suitable for immediate planting, need to be laid to natural ventilation to dry, when drying, it should be noted that the seeds should be laid with a layer of plastic film, can not be directly dried on the cement floor or asphalt road. Generally, the wheat seeds can be planted after drying.

Nowadays, wheat cultivation is almost all mechanical and automatic planting, and there is very little manual sowing; This requires that there is no residue in the wheat seeds, <>

It is stipulated that the wheat seeds are dry and slippery, and they can be smoothly slipped off in the planting bin to ensure the evenness of the wheat seeds sown in the ground; After wheat seed dressing, because of moisture and medicine, wheat seeds will swell, and some will be sticky, which will seriously affect the scale specified in the planting bin, resulting in insufficient wheat seeds sown in the ground, endangering the production of wheat, or because there is sticky agglomeration on the surface of wheat, blocking the pipe of the planting bin, so that the problem of broken ridges occurs in planting. The hazard of wheat germination rate is generally related to the hazard of seed quality and storage standards, in which the more moisture of the seed is stored, the longer the storage time, and the <>

The more harmful it is to the bud rate, the more it can not even bud. However, the wheat in the information you asked about is obviously dried after being mixed with chemical fertilizer, not to mention that your moisture content is less than 12 points, even if the moisture content of wheat is 13-15 points after seed dressing, storage for seven days has no effect on the germination rate. Due to the normal storage premise, the moisture content of the seeds is 13-15%, and it must be stored for at least one month before it will be significantly harmful to the germination rate.

After seed dressing, wheat can be stored casually and infiltrate into the residue, which will also cause some harm to the germination rate, and at the same time, it is also necessary to pay attention to staying away from the fire source to prevent the reduction of the medicinal power of the seed dressing.

Under normal circumstances, it can be sown after about 4 hours, and it is determined according to the actual situation, and 7 days may affect the germination rate.

If it is stored for 7 days, it may affect the emergence rate, and it may also cause the seeds to be difficult to germinate.

Every other day will do. Of course, if it is stored for too long, then the seeds may be inactivated.

The wheat seed in the next year can be germinated, if it is planted in a small area, it is no problem, the wheat seed is different from the corn seed, the wheat seed of the wheat seed subsidiary, you can also use your own wheat to make the wheat seed, the corn seed is a hybrid to obtain the seed company seeds, but in actual life, farmers basically do not use the aged wheat seed, if you plant a large area, you can.

Wheat types: Winter wheat and spring wheat are divided into two types according to the sowing date. Winter wheat is the main source in China.

Winter wheat in the growth process of the ability to resist the cold is very strong, its seedlings can survive the winter, when spring comes, the seedlings divide quickly, squat to grow up, winter wheat grinding powder is very delicious.

Spring wheat has a strong drought resistance, short plants and large ears, and a short growth period, which is suitable for spring sowing, but it is not as delicious as winter wheat flour.

Spring wheat is planted in a very cold place in winter, because the winter is too cold to be sown, so it is planted after the beginning of spring, which is called spring wheat; Winter wheat is planted in slightly warmer places, sown in winter and harvested in summer, for example, spring wheat in northeast China, and winter wheat in North China and its south.

Winter wheat should be sown in autumn and harvested in late spring. In China, it is generally bounded by the Great Wall, with the north as spring wheat and the south as winter wheat.

Corn seeds can still be planted every other year. [Happy].

In order to ensure that corn seeds still have germination power in the next year, it is necessary to meet the appropriate moisture content of the seeds before storage, the temperature (3-4) of the suitable storage environment and the relative humidity of the air, pay attention not to use plastic bags to pack seeds (this will hinder the normal breathing of seeds, causing heat injury, mildew and deterioration), and you can add a little insect control and other medicines. It is usually easy to store in the north, except in the south in a seed cryobank.

Abstract Dear, hello, wheat seeds can be stored for 3-5 days after being mixed with pesticides.

It is affected by the pesticide safety interval. The coating can be left for a longer period of time.

Sowing can be continued the following year.

The effect of the drug is gone. But it's still toxic.

Germination rate decreases.

It has little to do with mixing medicine.

How long can wheat seeds be stored after being mixed with pesticides? Can I continue sowing the second year? Will the germination rate be reduced Professionalism is required.

Hello dear, wheat seeds can be stored for 3-5 days after being mixed with pesticides. It is affected by the pesticide safety interval. The coating can be left for a longer period of time. The second year can continue to sow seeds, and the effect is gone. But it's still toxic. The reduction of germination rate has little to do with the mixture.

Dear, I hope you can be satisfied with my reply, and I look forward to your praise Thank you! Happy every day.

It takes a day after wheat dressing to sow seeds, but the premise is that the agent on the wheat seeds is completely dried, if the agent is not dried, it cannot be sown, so as not to affect the effect of seed dressing. At the same time, when sowing wheat, it is necessary to select humus soil with deep soil and rich nutrients as the base soil for planting.

1. One day later

It only takes one day after the wheat is dressed to sow seeds, provided that the agent on the wheat seeds is completely dry. If the agent does not dry after a day, then it is necessary to continue to dry until the agent is dry. Moreover, wheat seeds can only be stored for a maximum of seven days after seed dressing, otherwise the germination rate of the seeds will decrease, affecting the yield.

2. Select the soil

When sowing wheat, you need to choose humus soil with deep soil layer, good water and fertilizer retention as the base soil, and you need to renovate the soil before planting, and expose it to the sun to clean up the bacteria and pests in the soil, and you can also mix fertilizer into the soil to improve the fertility of the soil.

3. Carry out sowing

When sowing wheat, the seeds can be spread evenly in the soil and the seeds can be covered with soil. After sowing, you can spray non-polluted river water to the wheat field to keep the soil moist, promote the germination and growth of wheat seeds as soon as possible, and also provide full sunlight for wheat and make the plants grow better.

4. Post-management

After waiting for wheat planting to germinate, you can provide it with nitrogen fertilizer, phosphorus and potassium fertilizer as the supplement, improve the growth rate of the plant, and also regularly replenish water for the wheat, so as not to dry up the plant due to lack of water, and can also spray the wheat with sterilization and insecticide to make the plant grow healthily.

Wheat seeds and fertilizers will affect germination rate for half a month from the start of the stove. Urea, in particular, can inhibit young roots and shoots of crops.

Wheat cultivation techniques.

The crop grows well on both acidic and slightly alkaline soils, but the most suitable soil pH is to.

Farming and land preparation.

The land preparation of the crop in the dry land should be based on the deep tillage layer year by year, combined with the application of organic fertilizer, and the improvement of water and fertilizer conservation, and the land preparation should be carried out according to different multiple cropping forms. That is, the previous harvest is earlier, such as spring corn, sorghum, tobacco, etc., which calendar harvest should first be shallow ploughing and stubble, and then deep turning the kang soil, so that the residue rots and accepts the autumn rain, shallow rake after the rain, reduce evaporation; The other category, such as sweet potato, cotton, etc., has a tight harvest time, and if the conventional method is used, it is bound to delay the sowing date, which is one of the important reasons for the low yield of the crop in the southwest region. Therefore, on the one hand, the implementation of loosening soil and moisture between the rows in the previous crop and later period, and then plowing and leveling when planting wheat; On the other hand, it is advocated to dig potatoes, level the ground, fertilize, sow and other continuous operations to ensure that the crop is sown in a timely manner.

High-yield technology. 1. Pay attention to the selection of high-fertilizer and water plots. High-yield and high-quality crop varieties require that soil nutrients must be comprehensive and sufficient in order to meet the needs of high-yield cultivation, so it is advisable to choose plots with high quiet dressing power and good watering conditions, and to increase organic fertilizer and adopt formula fertilization technology.

2. Pay attention to late sowing at the appropriate time, and determine the appropriate basic seedlings according to the characteristics of the variety. It is necessary to prevent excessive sowing volume, resulting in passive post-management.

3. Pay attention to prevent lodging and reapply jointing fertilizer. Some of the high-quality crop varieties promoted are not resistant to lodging, especially for wheat fields with too large groups, a chemical control treatment must be carried out before returning to jointing, and paclobutrazol or wheat yefeng can be sprayed. It is necessary to reapply jointing fertilizer to control the formation of excess falling ears and promote large ears and more grains.

4. Pay attention to watering grouting water, wheat yellow water, and spraying foliar fertilizer to prevent premature aging. Watering grouting water plays an important role in increasing granularity weight and preventing dry and hot air. In dry weather, the use of wheat water is conducive to intercropping and preventing premature aging.

In the first half of May, combined with the prevention and control of pests and diseases, spray 2 to 3 times of foliar fertilizer, such as potassium dihydrogen phosphate, which can reduce the harm of dry and hot air and increase yield.

5. Pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality crops are more susceptible to pests and diseases, such as sheathrody and powdery mildew, and aphids occur earlier and heavier than conventional varieties. It should be prevented and treated as soon as possible according to the forecast.

6. Spray the crop treasure once when the crop has just broken and reached about 60% to 70% before heading and flowering, so as to activate the biological enzyme activity in the crop, promote coordinated growth, enhance the photosynthesis of functional leaves, significantly reduce the empty stubble rate, improve the seed setting rate and 1000-grain weight, so as to achieve the effect of increasing yield.

Under suitable conditions, it is generally about 7 days.

Winter wheat is sown in one month and harvested the following year (mainly south of the Great Wall).

Spring Wheat: Sow after the Spring Festival and harvest in the month (mainly north of the Great Wall).

In recent years, with the global warming, wheat has often grown vigorously before winter and frost damage occurred in winter and early spring when sown according to the previously determined sowing date.

In order to cope with the warming situation, the suitable planting date for winter wheat should be appropriately delayed compared with the suitable planting date in the past, and according to calculations and experiments, the suitable planting date should be from October 8 to 20.

Many winter wheat fields have the problem of large sowing amount to varying degrees, resulting in strong growth before winter and spring, weak stalks, easy lodging, many ears and small ears, easy to premature aging, low yield and other problems.

The suitable sowing amount per mu of sowing and watering land at the appropriate time is kilograms, and the sowing amount per mu is reduced or increased by kilograms in advance or postponed by 1 day outside the suitable sowing period.

Appropriate depth. Strictly grasp the sowing depth of 3-4cm.

Under suitable conditions, it is generally about 7 days.
