New Technology of Transplanting Corn Seedlings
Zhangwu County is located at the southern edge of the Horqin Desert and has suffered a rare spring drought for three consecutive years. The corn preserves seedlings and the farmers' income is reduced. The county's agricultural economic losses are enormous. In view of this situation, we have experimented and researched the new technology of transplanting corn seedlings to achieve no reduction in production and no reduction in corn production in the disaster year.
1. The experimental site is the Agricultural Science and Technology Demonstration Base in Tiger Village, Xinglongshan Township. The variety is Xintiedan No. 10, with a length of 30 meters and 80 rows and a density of 3300 trees per mu.
2. The site selection site will be a flat, leeward plot. In mid-April, the site will be a hoe-shaped hoe, fill the bottom water, and make enough fertilizer for the farmer.
3. Sowing seedlings The treated seeds (skin seeds and pesticide seed dressings) should be sown uniformly in a single grain of 7 cm 7 cm row spacing. The sowing date will be in the middle or late April and timely sowing. After the emergence of two leaves as the soil water poured 1-2 times.
4. Colonization and transplanting When the corn grows to 3 leaves and 1 heart, it can be transplanted and colonized. Before planting, the seedbed will be poured with adequate amount of bottom water, and rooting will be minimized when raising the seedlings. Select cloudy days or morning and evening watering planting, choose Qi, strong seedlings colonization. After planting, the weather conditions were filled with water once. Other management with live field.
5. Analysis of the results Through the centralized and high-quality management at the seedling stage, there was no delay in the seedling stage after transplanting and the birth period was slightly advanced. Transplanting seedlings increased the yield of 107.4 kilograms per mu compared to direct seeding corn. It can be seen that the harvesting of the corn production in the severe drought-stricken areas and timely early planting of the maize have been very difficult. The poor lyrical condition has severely restricted the planting and seedling of the corn. Transplanting seedlings has become an effective new technology.
In recent years, due to the reduction in the price of corn and the increase in the cost of production, many farmer's corn only earns 100 yuan per mu, or even less, and the enthusiasm for production declines. Seedling transplanting technology can alleviate the impact of spring drought, reduce production costs, increase production, increase farmers' income, and promote agricultural development. In summary, there are the following benefits: 1 Maize seedling transplanting is not affected by the spring drought, appropriate early sowing, visible planting can be determined. Through the centralized management of concentrated seedlings and fertilizers, the cultivation of strong seedlings will not be limited by the difference between spring drought and drought, which will lay a good foundation for achieving high and stable production of corn. 2 Maize seedling transplanting technology saves water, saves labor, and saves production, which reduces production costs. Through experiments, seedlings transplanting and transplanting were conducted with less irrigation than direct seedlings at the seedling stage, saving 7 cubic meters of water per mu, saving 2 degrees of electricity use, saving 0.2 labors, and reducing costs by 5 yuan; seedling transplanting was similar to single grain unicast. The amount of 1 kilogram per acre is used. Compared with 3 kilograms of seeds for direct seeding, it can save 2 kilograms of seeds and reduce the seeding cost by 8 yuan. In total, the production cost can be reduced by 13 yuan per acre. 3 Maize seedlings transplant seedlings to raise seedlings, preserve seedlings, increase output, and increase income. Through transplanting seedlings, there can be selective planting, with 3241 seedlings per acre. However, due to spring drought and seeding technology, live seedlings can only protect 639 seedlings per acre. Although the output of single panicle was not as high as that of the direct seeding field, it increased the yield by 19% with density, and increased the income by 75 yuan per mu.
In summary, corn seedling transplanting technology reduces production costs, increases production, achieves high and stable production of corn, increases farmers' income, and largely ends the corn production by days of eating, so it should be in the spring Drought-prone areas are being promoted.
