Selection of Super High-yield Wheat Varieties and Cultivation Techniques in Henan Province
Wheat is one of the food crops that our people can survive. Therefore, the selection of wheat varieties and key cultivation techniques are issues that every grain grower is concerned about. Let's take a look at the selection of wheat super high-yield varieties and their key cultivation techniques in Henan Province.
1. Selection
In the process of selecting varieties, Henan Province has a certain high yield potential in the process of wheat planting. Therefore, you can choose Yumai 49 variety, Xinmai 9 variety, Yumai 66 variety, Zhoumai 16 variety, etc. . In different regions, scientific selection should be made according to the situation of the field, planting time, etc. At the same time, in the actual planting process, the amount of seeding should be appropriately increased, and the density should be strictly controlled. For example, the seeding rate should be controlled at about 122 kg/ha, and adjusted according to the actual situation to gradually increase the yield of local wheat to achieve the intended planting purpose. .
2. Cultivate the land
For the growth of wheat crops, land has a more important role. Only when the land has a certain fertility, can the production efficiency and quality be gradually increased, the crop yield can be increased, and the intended planting purpose can be achieved. Therefore, it is necessary to do a good job in soil cultivation, and according to the actual growth requirements of wheat, rationally carry out the medium tillage work, and appropriately add nitrogen fertilizer (12kg/kg soil), quick-acting phosphorus (80mg/kg soil), quick-acting potassium (30mg/kg soil), etc. Gradually increase the content of organic matter in the soil. At the same time, we must pay attention to the management of organic fertilizer, return the straw of corn and wheat to the soil, and improve soil fertility.
3. Seeding measures
In the process of actual sowing, we should formulate a sound management plan according to the requirements of wheat production, clarify the factors of high production and key content, do a good job in fine farming, and establish a special deep-plowing mechanism. During the actual work, the depth of the tillage should be controlled between 24cm and 27cm, the width should be controlled at about 17cm, and the line spacing should be controlled at about 24cm. At the same time, it is necessary to do a good job in testing the soil water content. Only when the water content is above 18.1%, the seeds can be sown.
4. Fertilization measures
Farmers should formulate a sound fertilization plan and apply a reasonable working method to deal with it. On the basis of improving soil fertility, it should be topdressed according to the growth of the seedlings to achieve good treatment. During the actual fertilization, the dosage of organic fertilizer should be controlled at about 45100kg/ha, and the nitrogen fertilizer should be controlled at 250kg~280kg/ha. If the local soil fertility is high, the nitrogen fertilizer should be measured at 75% to improve work balance. In the process of topdressing, it should be rationally treated according to the wheat panicle type, and the advanced topdressing method should be used to carry out all aspects of work, and a special fertilization management mechanism should be established to gradually improve the reliability and effectiveness of the work. For example, in the period of wheat returning to green, rising period, jointing period, etc., nitrogen fertilizer should be used reasonably, and the test work should be done. The dose of nitrogen fertilizer should be controlled according to the test results, so as to improve the reliability and effectiveness of fertilization management.
5. Field management measures
In the process of managing the wheat field, it should be divided into the pre-winter management stage, the spring management stage and the later management stage. According to the local actual situation, a perfect weed management plan and fertilizer and water management plan should be formulated according to the growth index of the seedlings. It carries out strict management and control and gradually improves management efficiency. For the pre-winter management work, since the emergence time of wheat in Henan Province is around December 21 every year, it is necessary to manage the fertilizer and water. In the spring management phase, the time should be controlled from February 11 to April 21 every year. For post-management, the time should be controlled around April 21 every year to improve the reliability and effectiveness of management engineering.
The above is all about today's wheat planting. It is recommended that farmers who need it can pay attention to Hui Nong.
A key box is a special box for storing keys. It is usually made of cold rolled steel. It is a kind of steel office furniture. The biggest difference between it and the ordinary box is that there are many hooks on the key box for hanging the key. Using a key box to store keys can effectively store and classify keys. So that enterprises can be high quality, efficient management.
The wall mounted key box is a secure storage solution designed to hold and organize keys. It typically features a durable metal construction with a lock or combination lock mechanism to prevent unauthorized access. Key boxes come in various sizes and styles, ranging from small boxes that can hold a few keys to larger cabinets that can store hundreds of keys. They are commonly used in commercial buildings, hotels, car rental agencies, and other establishments where multiple keys need to be securely stored and easily accessible. Key boxes help to prevent key loss, theft, and unauthorized access, ensuring the safety and security of the premises.
