1 .Fumin 985 Maize Seed Introduction
The variety sources of 1 and Fumin 985 maize seeds are M80 1× FM 1 1. Mid-maturing spring maize populations in East China and North China are earlier than the control Xianyu 335 133 days. The seedlings have purple leaf sheaths and green glumes. The number of leaves per plant is 65,438+09, the panicle is tubular, the number of rows per panicle is 65,438+06-65,438+08, the panicle length is 65,438+08.7 cm, the panicle diameter is 5.65,438+0 cm, the panicle axis is red, the grain is half-horse-tooth yellow, and the weight of 100 grains is 36.7 grams.
2. The bulk density of Fumin 985 corn seed is 76 1g/L, the crude fat content is 4. 16%, the crude protein content is/kloc-0.10%, the lysine content is 0.29%, and the crude starch content is 73.3/kloc-0. The key point of cultivation technology is to choose plots with medium fertility or above.
3. This variety conforms to the national maize variety approval standard, and is suitable for planting in the eastern mountainous area of Liaoning Province and parts of northern Liaoning Province in the middle-maturing spring maize area of Northeast China and North China, most parts of Baicheng City, Jilin City and Tonghua City of Jilin Province, parts of Changchun City, Liaoyuan City and Songyuan City, and Chifeng City, Wulanhaote City, Hohhot City, Tongliao City and Baotou City in the first accumulated temperature zone of Heilongjiang Province.
Second, matters needing attention before sowing corn seeds
1. Plot selection: The planting area should be far away from industrial and mining areas and highway environment to avoid the influence of urban pollution and industrial production on corn growth. The plots suitable for corn sowing should have loose soil, deep soil layer and good fertilizer conservation performance, and cannot be planted continuously in the same plot during the planting process, otherwise it will easily lead to the spread of pests and diseases.
2. Scientific land preparation: In the process of land preparation, excessive evaporation of soil moisture should be avoided as much as possible, and no large clods can appear in the raked stratum, and the overall effect should be that the upper part is empty and the lower part is solid. In the season of alternating freezing and thawing, it is necessary to arrange the plots in time so that the surface cracks can be leveled in time, which is beneficial to soil moisture conservation and water improvement.
3. Rational fertilization: In order to ensure sufficient nutrition supply for seeds in the development process, it is necessary to effectively cultivate soil fertility and improve the physical properties of soil by applying base fertilizer, which is beneficial to the root system development of corn seeds.
4. Reasonable close planting: the growth period of corn is short and the water demand is large. Henan and other central plains areas have abundant precipitation and high temperature in summer, so it is more suitable to plant corn twice a year.
