Corn spring planting technical guidance
Since the spring of this year, the temperatures in the northeastern region have been higher than normal, especially since the recent warmer temperatures have been rising. It is expected that the sowing date will be ahead of schedule. In view of the current conditions of the northeast weather and the actual corn production, the corn expert steering group of the Ministry of Agriculture and the National Agricultural Technology Extension Service Center proposed corn seedling springing technology with the focus on "early spring soil preparation, timely grabbing of early planting, and striving for complete seedlings". . The first is to prepare the land for grabs and prepare for spring broadcasts. Most areas in the northeastern part of the Northeast have more precipitation, and the area of ​​wet landfills and unscheduled autumn soil preparations is higher than normal. Due to the rapid temperature rise in spring and accelerated soil defrosting, it is expected that the time for soil defrosting will be earlier than that of previous years, and the time for spring soil preparation will be shortened, and the agriculture will be tight and the task will be heavy. At the same time, the hot and cold changes in the spring weather are fierce and the recovery is not stable. All localities must pay close attention to weather changes, prepare as early as possible, prepare for early broadcast, and create favorable conditions for appropriate sowing. The second is a scientific layout, and it is strictly forbidden to plant in other areas. According to the local natural ecological conditions and corn production level, suitable varieties suitable for maturity, high yield and stable yield, and rapid dehydration at the end of the season should be selected as the best maize varieties approved by the national or provincial level according to local conditions (refer to the leading maize varieties promoted by the Ministry of Agriculture in 2014). Maize varieties of different types and ripening periods in the same producing area should be properly matched to avoid planting long-growing varieties. Prevent species from being planted in different regions to ensure safe maturity and increase corn yield and grain quality. The third is selected varieties, timely robberies early broadcast. Since last winter, high temperatures are conducive to the wintering of germs and pests (eggs). It is necessary to directly use coated seeds or seed coating to prevent seedling pests and diseases. For lands with good lyricism or bottoms, the use of mechanical precision seeding techniques to plant seedlings, give full play to the advantages of fast machine operations, speed up the sowing schedule, to ensure that the sowing within the best sowing date. For the poorly-conditioned plots in the traditional drought-stricken areas, drought-resistant sowing techniques such as “seed waterâ€, mulching, drip irrigation under the membrane, etc. were adopted, and sowing was conducted at the appropriate time. For low-lying land and low-temperature and multi-humidity lands, drainage shall be timely and riddled with scattered shallow lands. We will strive to complete the planting before May 20th to improve the quality of sowing, and strive to broadcast all seedlings. The fourth is the rational close planting to strengthen seedling management. According to the characteristics of varieties and the local conditions, soil fertility, fertilization level and management level, comprehensively determine the appropriate planting density and construct a reasonable population structure. The general soil fertility is higher, and the selected variety is a dense-resistant variety. The suitable planting density is 4000~4500 per mu. Timely seedlings will be established to promote the early development of roots and plants, and to achieve complete seedlings, Miao Qi, uniform seedlings, seedlings strong, lay a good foundation for high yield and stable production of corn.
