It is very important for wheat to be harvested and seeded. Let's talk about how wheat is mixed. Everyone knows that planting crops, Miao Qi and Miao Zhuang are the foundation of high yield, and there is also the saying that "Miao is good for half a year." In order to achieve Miao Qi, Miao Zhuang, fine land preparation, proper shallow sowing and timely sowing are all important. It is also necessary to ignore the nutrition of seedlings and prevent pests and diseases. This requires seed dressing measures.
Seed dressing is a measure in which fertilizers, pesticides, and wheat seeds are mixed in a certain ratio, and then repeatedly mixed, and finally the fertilizer and the agent are uniformly attached to the surface of the seed. Because the seeds are in the dormant stage of the crop, and the most easy to concentrate on treatment, no matter whether it is mixed with fertilizer or mixed medicine, it is the least used, the simplest operation and the most obvious effect. For pests and diseases that rely on seed transmission, seed dressing is almost the only prevention and control measure, which not only eliminates the seed bacteria, but also protects the seedlings from infestation.
The specific method can be repeatedly turned on the ground with a raft, or can be shaken back and forth with a plastic bag, or treated with a specially made "mixer". In some areas, the breeding stations or agricultural technology stations have been equipped with seed coating equipment, which can be said to be the highest level of seed dressing. There are also some medicinal agents that can be sprayed onto the seeds with a small amount of water, sprayed and squirted, then stuffed, or even soaked with fertilizer or syrup. Soaking seeds and seed dressing, all the same, can make the seeds "with fertilizer and medicine."
Here is a special talk about wheat seed dressing. For local pests and diseases, fungicides, insecticides, growth stimulating hormones, etc. may be used alone or in combination, depending on the specific circumstances.
When wheat is planted, it can be mixed with triazolone wettable powder or seed coating at a ratio of 0.03% by weight of dry seeds, which can effectively control various diseases such as stripe rust, leaf rust, powdery mildew, sheath blight, smut, white stalk and so on. It also has a certain stimulating effect on wheat growth.
Underground pests such as wheat golden worms can be seeded with 50% phoxim emulsifiable concentrate and 48% chlorpyrifos (Lesburn) in a ratio of 1:40:400 for medicament, water and seeds.
In some high-yield areas of wheat, if 50% of chlormequat 250 grams, 5 kg of water, stir evenly sprayed on 50 kg of wheat, and then piled up for 4 hours, until the liquid is fully absorbed by the wheat seeds, sow, Can reduce wheat lodging.
