It is time to see sowing autumn wheat. Wheat seed processing is often overlooked by many farmers. Dealing with wheat seeds plays an important role in its growth. It is the key to pest resistance, and it is also an important measure to increase production. .
There are four methods for wheat seed processing
Insect repellent treatment method can be used for wheat ground pests such as earthworms, cockroaches, and needles, etc., can be used 1605 emulsion seed dressing, stuffy for 4 to 6 hours; or with phoxim emulsion seed dressing, stuffy stuffy more than 4 hours.
Drought treatment method Add 3 kg of crushed superphosphate to 50 kg of clean water, stir thoroughly with a wooden stick, and then stand and pour the supernatant into another container, that is, 6% of the superphosphate leachate, then add 50 Boric acid stir, that is, a mixture of phosphorus and boron. The phosphorus-boron mixture was sprayed at 10% of the dry weight of the seeds, and the seeds were turned while spraying. Each seed was required to be evenly soaked in the solution.
Plant growth regulator treatment method soaked with flourodine soaked per kilogram of wheat seed 1 ml stock solution plus 2 kilograms of water diluted mix, submerge the seeds for 8 to 24 hours, remove the seeds dry to sow. Seed soaking in this method can enhance drought resistance, cold resistance, disease resistance, and increase wheat growth potential and vitality.
The micro-fertilizer treatment method is insensitive to zinc, but the yield increase is significant after application. The seed dressing is applied at a rate of 5 to 6 grams of zinc sulfate per kilogram of seed. The zinc sulfate is weighed, dissolved in a small amount of water, sprayed on the wheat seeds, and sprayed while stirring. A small amount of wheat seeds is mixed well for a few times.
Identify the germination rate and make five measurements
The soil was measured in two portions of wheat, 100 grains each. Choose a fertile loose soil with good water retention performance. Turn the soil to a level of 30 square centimeters, open two small furrows, and dig the depth about 3 centimeters. Spread the two wheat seeds evenly into the two furrows and cover the soil. After 7 days, the rate of budding can be calculated by digging out the wheat seeds.
The bricks were measured in two portions of wheat, 100 grains each. First use the bricks to mark the area on the flattened soil, spread the two wheat varieties in the area of ​​the two bricks, and press the bricks. Penetrate the bricks, pour the bricks once a day and keep them moist. Check the germination rate after 3 days.
Fine sand was measured by taking 2 varieties of wheat, with 50 grains each. The wet sand was placed in two pots. Two grains of wheat were sowed separately into two pots of sand. The depth of sowing was about 3 cm. After that, the humidity of the fine sand was kept. After 7 days, the seeds were plucked and the germination rate was calculated.
Wet towels were measured on 2 kinds of wheat seeds, 50 tablets each. The wheat seeds were first soaked in water for 24 hours, then 2 wheat varieties were placed on two wet towels and the wheat seeds were rolled in wet towels. Keep the towels moist every day and measure the germination rate after 7 days.
Toilet paper was measured by taking 2 types of wheat seeds, 50 tablets each. First wet the toilet paper and lay it flat in the vessel. Put the wheat seed on the toilet paper, put a layer on it, and cover a layer of toilet paper until the wheat seeds are finished. After the toilet paper is kept moist every day, the germination rate is calculated after 7 days.
Wheat dressing, to avoid the three errors
The better the color of the seed coating agent after seed dressing, the better the color is to serve as a warning. It is to distinguish whether the seed is mixed with the seed coating agent so that the seeds of the seed coating agent mixed with the pesticide are not mistaken by humans, livestock and poultry. food. Therefore, the depth of color has nothing to do with the quality of seed coating agents.
The more concentrated pesticide coating agent, the better the efficacy of pesticides, indicating that the added pesticide is highly toxic, which in itself is undesirable. If you only rely on seed dressings and pesticides to prevent and control underground pests, it is a cup of water. For lands with severe underground pests, the best method is to rotate crops or mix insecticides in chemical fertilizers. It cannot rely solely on seed coating agents.
Large bottles of seed dressings are more affordable, and the amount of medicine is effective enough. Many farmers choose seed dressing agents. The same price is more for large bottles. It feels that the large bottles have more full doses and the effect will be better. This is only a psychological effect, the effectiveness of pesticides depends on the content and dose of active ingredients, seed dressings are often low in effective ingredients will compensate for the lack of active ingredients in dose.
Fruit powder is a solid powder obtained by beating, filtering, spray and drying fresh fruit. It is bright in color and delicious in taste. It is a good helper of food additives and nutritional supplements
