What are the key points of applying the alternate planting technique for corn rows of varying widths?

I. Overview of Intercropping Technology of Corn with Wide and Narrow Rows Wide and narrow row alternation is a new and efficient corn planting technology. There are some differences between the wide-row planting method and the traditional corn planting and land preparation methods. The traditional corn planting method is uniform ridge planting, half of the seedlings are sown, and the soil tillage is shallow. This planting technology is to level the land and plant in an alternating wide and narrow way, with single-seed sowing, deep loosening of the soil, and high stubble. Usually, deep soil loosening and fertilizer application are carried out during the widening process at the corn jointing stage. Stubble is left in the autumn harvest period. The height of the stubble is usually about 39cm, and it should be rotated by a rotary tiller. It rots in the soil and turns into a wide line through the fine lines of rotary tillage. Next year, corn can be planted directly in the wide rows of the courtyard, and then a new production capacity is formed. This repeated operation is an alternating row planting technology. II. Advantages of Intercropping Technology of Corn with Wide and Narrow Rows 1. Ensuring Soil Temperature and Humidity When using the wide-row and narrow-row alternating planting technology, in order to ensure that the soil has the appropriate humidity, a plastic film should be covered on the soil to avoid the loss of soil moisture from contact with the atmosphere. In addition, the covering film can also prevent the soil temperature from continuing to rise after sun exposure, causing the evaporated water to condense on the surface of the covering and then flow back to the soil in the form of water droplets, providing sufficient water for the growth of corn. 2. Achieving Rational Utilization of Land Usually, before using the corn wide-row and narrow-row alternating planting technology, the sowing area needs to be divided into narrow-row planting area and wide-row non-planting area, and then the sowing method is divided according to the land conditions of the corn. Sufficient planting time is provided for the non-planting area to lay the foundation for corn planting next year. Therefore, when adopting the narrow-row alternating planting technology, both the land division problem and the corn planting problem should be considered to achieve the recycling of land.

The production process of quick-frozen waxy corn and vacuum-packed corn

Frozen Sweet Corn Production Process Peeling and shaping - Roller brush dry cleaning - High-pressure cleaning - Blanching (approximately 15-25 minutes/time) - Pre-cooling - Ice water cooling - Basket freezing → Packaging → Refrigeration (1) Suitable harvesting period for sweet and glutinous fresh corn. Harvesting is very important. Different varieties have different harvesting periods, and the quality varies greatly depending on the harvesting time of the same variety. The suitable harvesting period for fresh glutinous corn No. 1 is 22-24 days after pollination. The harvested ears should be processed promptly. The entire process from harvesting to completion must be completed within 10 hours. Corn with full grains, yellow or light yellow color, uniform color, no mottled grains, uniform and neat grain size and arrangement, and no serious problems such as bald tips, missing grains, or insect damage should be selected. (2) Cleaning. First, use a hair roller cleaning machine for dry cleaning to remove surface dust from the corn, and then use an air bubble spray cleaning machine to rinse the corn with clean water and remove impurities. (3) Blanching. Blanching is the most crucial step in the processing of tender corn. The temperature and time of blanching must be strictly controlled. Blanching has the following effects: It can inactivate enzymes in the corn tissue. Even low-temperature refrigeration will not inactivate enzymes, which continue to undergo slow physiological and chemical reactions, destroying the nutritional components of the grains; Blanching can also kill some microorganisms and insect eggs, ensuring product hygiene and food safety; The air in the blanched corn kernels is partially expelled, reducing the expansion pressure during ice crystal formation during freezing, increasing resistance to expansion pressure, and correspondingly reducing the degree of oxidation of the raw materials, maintaining the color and nutrition of the product. Boiling water or steam can be used for blanching, at a temperature of 93-100℃, and the blanching time is approximately 15-25 minutes/time. (4) Cooling. The blanched corn kernels should be cooled immediately; otherwise, the residual heat will seriously affect the quality, such as darkening of the color, increased dry matter loss, prolonged freezing time, wasting energy, and providing conditions for microbial growth. Therefore, cooling must be timely and thorough to ensure the color and quality of the product. In order to save water, a segmented cooling method can be used. First, use a spray method to reduce the temperature of the corn kernels at around 90℃ to 25-30℃; then, soak and cool in ice water at 0-5℃ to reduce the temperature of the center of the corn kernels to below 5℃.

Corn mechanical harvesting sets a new record in Northeast China; what did farmers learn in the "field classroom"?

From the corn mechanical grain harvesting technology on-site observation and training meeting held in Tongliao City, Jilin Province from January 12 to 14, it was learned that the per mu yield of a 20-mu high-yield demonstration field in Qianjiadian Town, Korqin District, guided by the corn expert guidance group of the Ministry of Agriculture and Rural Affairs and the cultivation physiology innovation team of the Institute of Crop Sciences, Chinese Academy of Agricultural Sciences, reached 1234.88 kg, setting a new high-yield record for large-scale planting of mechanical grain harvesting of corn in Northeast China; the per mu yield of the 1000-mu demonstration field exceeded 1000 kg, an increase of more than 450 kg compared with the average yield of local farmers. According to calculations by the agricultural technology department, the average net income per mu in the demonstration field was 1529.4 yuan, an increase of 918.9 yuan per mu compared with farmers, greatly enhancing the competitiveness of Tongliao's corn industry and exceeding the commitment to help local farmers increase production and income.

Corn facts that farmers need to know

China is a major producer of livestock and poultry, and corn is the main raw material in their daily diet. Improving the utilization rate of corn is one of the important measures to promote China's livestock and poultry production, save feed resources, and alleviate the shortage of feed in China. The particle size of corn has an important impact on the nutrient metabolism, digestive tract development, and production performance of livestock and poultry. Studies have shown that appropriate crushing of corn can significantly improve feed conversion rate and animal production performance, and is beneficial to feed processing. However, although excessively fine grain feed can increase feed utilization rate and reduce waste, it will also increase processing costs and cause digestive diseases in livestock. In recent years

Problems and countermeasures in corn cultivation techniques, technical knowledge, come and learn!

Problems in corn cultivation: 1. Failure to select suitable varieties. In recent years, although the country has advocated for the vigorous development of agriculture and implemented various agricultural policies benefiting the people, providing farmers with a large amount of technical support, due to the low level of education of most farmers, their awareness of agricultural planting remains in the past, and they cannot effectively utilize modern scientific planting techniques. Especially regarding the selection of corn varieties, some farmers' thinking remains in the past, believing that varieties can be chosen arbitrarily, and as long as sufficient fertilizer is applied later, there will be no major problems. This is a serious mistake. Poor corn seeds, even if a large amount of fertilizer is applied later,
