Study on Mechanical Testing of Corn Sprouting

Corn sowing machine sowing is through the selection of a suitable sowing machine soaking, germination, drying corn seeds sown to the appropriate soil, to achieve corn seeding, germination sowing and rooting treatment, to increase the purpose of increasing corn production. Embryonic bud refers to that the radicle length grows about 1cm. Embryonic bud refers to the germinated sprouting outcrop. The seed treatment is to pick out the ungerminated seeds from the germinated corn seeds and dry them for 4~5h to adapt to the long-extracted embryos at room temperature. Roots, so that it does not affect the machine broadcast; rooting treatment is through the airing or sowing, so that the seeds have grown out of the radish or fall off brittle fracture.
Corn germination through root-cutting treatment has played a dominant role in seed germination of the radicles, each seed can increase two or three fibrous roots; improve drought resistance at the seedling stage, is conducive to corn seedlings; gang nutrients, reproductive growth at the same time, to meet the corn The demand for increased water and fertilizer will accelerate the growth rate, give full play to the green function of plant leaves, effectively use natural resources such as light, water and fertilizers, promote the growth of corn plants, prevent the growth of corn seedlings, plant weakness, resistance to lodging, grain Falling and other phenomena occur. Throughout the growing period, plant traits were better than those in the control group. Plant height, ear height were reduced by 6~9cm and 3~8cm. The length of bald tip was reduced by about 0.3cm, the number of rows of grains was increased by 0.5~1.5, and the number of spikelets increased by 30 grains. , Thousand kernel weight and production increased by about 3%.
Pregerminating sowing machine sowing 5 days earlier than ordinary dry sowing machine, the growth period is 2~3 days ahead of schedule, field growth period is shortened by 1~2 days, and the accumulated temperature is about 100°C. At the same time, it can reduce pests and diseases, and it is suitable for the current planting of fertility. The high-yield maize with a temperature of about 2500°C and a temperature of about 100 days has created the conditions for the summer maize iron-seedling machine. It basically solved the problems of short-term growth and insufficient accumulation of temperature in two-year-old flat cropping corn, which could not complete maturation and affect material accumulation. This will lead to a reduction in production, and at the same time, it will also solve the problem of wheat and corn crops intercropping that do not allow corn seeding, wheat harvesting to damage corn seedlings, and wheat harvesting in autumn.
Corn germination machine sowing can achieve closed sowing, drought protection, seedling fertilizer application, to achieve mechanization of corn sowing, improve the quality of sowing, standard corn spacing, plant spacing, to achieve a reasonable close planting, ensure scientific and reasonable corn high-yield group structure, in order to achieve corn The harvest has laid a foundation for the corn pregermination machine to standardize the corn spacing, which is conducive to the realization of corn harvest mechanization and the promotion of agricultural mechanization.
Finally, it should be pointed out that the pre-emergence corn seed is different from the dry seed which has not been subjected to the germination treatment and the seeder currently used needs to be further improved.
