Corn sowing should pay attention to four issues
1. The variety and quantity of fertilizers that are planted with fertilizers should be strictly controlled. Currently used corn planters and fertilizers are only about 5 centimeters apart from the feet and underneath. Fertilizers sown should be selected with high-quality compound fertilizers or diammonium plus fertilizers. Potash, as far as possible without urea. The total amount of fertilization does not exceed 20-25 kg/mu, preventing the phenomenon of burning after watering and heavy rainfall. In recent years, there have been occasions where seed burning has been caused by planting fertilizers, and farmers’ friends should pay close attention.
2. The time for watering should be strictly controlled: "The spring battle day, the summer battle time." Early harvesting of wheat after harvest has a lot of benefits for the growth and high yield of maize, but if the water is not watered in time within 3-4 days after sowing, the seeds will have the risk of “budsâ€, especially those Although the lyrical condition is slightly poor, it can make the seeds germinate, but it is not enough to make the land where the seeds sprout. Every year, because of the "sprouts," re-seeding and planting are also happening from time to time. Therefore, farmers should sow as early as possible according to the conditions of their plots and local water sources.
3. Chemical seed dressing In recent years, the occurrence of pests and diseases in corn seedlings has been aggravated and species have increased. Some corn seeds of seed companies have not been coated, and some corn seeds purchased by farmers are not sunburned or seeded. , Caused by the seed pests and Other underground pests lead to lack of seedlings broken ridge. Due to the large amount of wheat straw in the field after the wheat machinery was harvested, the wheat ridge was severely covered and the seedlings and seedlings were very troublesome. Therefore, the farmers' friends purchased the coated seeds of the regular enterprises when they purchased the seeds. Good seed coating agents contain both pesticides and fungicides as well as some regulators that stimulate seed germination. If the purchased corn seed is uncoated, it can be used to prevent diseases such as underground pests, seedling blight, etc., as well as insect pests of Laodelphax striatellus, thrips, etc., by using a large-formulated chemical seed dressing. Imidacloprid 20 g, 50% phoxim EC 100 Kejia 4 to 5 pounds of water mixed with 100 pounds of corn, heap stuffy 4-6 hours, slightly dried and mixed with 100 grams of 50% carbendazim after sowing.
4. Scientific use of herbicides and collocation of insecticide corn are susceptible to damage by the insect pests before and after sowing. Currently used herbicides such as B, A, and Metolachlor are used in production, as well as Yu Nongle and Ji Yu. Post-emergence herbicides should not be used in combination with organophosphorus pesticides, and should be used for more than 7 days even if they are used at intervals. Otherwise, they are likely to cause phytotoxicity and reduce weeding effects. In order to achieve multi-injection, reduce the number of field applications, and achieve the purpose of weeding and killing insects, herbicides and fenvalerate, marjoram and other pyrethroids can be mixed and sprayed. When using a pre-emerged closed herbicide spray, care should be taken to reverse the flow and increase the amount of water used. Because the wheat population in wheat fields this year is higher than in previous years, wheat ridges are thick and the amount of wheat straw in the fields is very large. Enough water to ensure the integrity of the film layer and weeding, pest control effect.
5XZ series Gravity Separator (Air blowing type)
Introduction:
1. This Blow Type Specific Gravity Cleaning Machine is to produce proportion segregation phenomenon under stress of aerodynamic and vibration friction of graininess material.
2. By adjusting wind pressure, amplitude and other parameters, larger proportion material will sink down and move bottom to up under stress of vibration friction; smaller proportion material moves up to bottom.
3. This machine is to remove blighted seed, budding seed, damaged seed (by insect), rotten seed, deteriorated seed, moldy seed, non-viable seed, seed with black powder sick and light impurities from wheat, corn, paddy, sunflower seed, melon seed, legume, etc.
4. At the same time, there is an angle on the right of vibration surface; the stone can be separated.
This machine is according to segregation phenomenon of granule and density under fluidization process, for achieve materials delaminating and mutual exchange, at the same time the wind pressure and amplitude need be adjusted. Specific Gravity Separator is used to classify materials according to density or specific gravity. This is important when seed and/or impurities are similar in size but different in density. The separator uses a vibrating perforated deck that can be tilted in two directions at various pitches. Air moving through the perforated deck separates the seed and any impurities by weight as the deck oscillates.
