Broadcast sowing planting method for millets

Abstract

The invention discloses a broadcast sowing planting method for millets. The broadcast sowing mode is adopted to sow two kinds of seed-grains at the same field simultaneously. A seed-grain I having resistance to weed killer A and having higher seedling plants at 3-4 leaf stage and a seed-grain II having no resistance to weed killer A and having shorter seedling plants at 3-4 leaf stage are selected and are pelletized respectively; then the processed two seed-grains are well mixed and sowed through broadcast sowers at a sowing density of 400 to 500 plants per square meter; waiting until the grain seedlings grow to 3-4 leaf stage, using the weed killer A to remove the grain seedlings of seed-grain II and keep the seed-grain I for continuous growth; waiting until the seed-grain I turn mature and harvesting. The method for sowing millets has changed the traditional planting mode; through selecting two kinds of seed-grains for broadcast sowing, the problems such as irrigation ears and surface soil hardening leading to dead seedlings caused by rainfall in rainy season are eased; dead seedlings caused by sunburn and earth surface transpiration are reduced; when the grain seedlings grow to 3 to 4 leaf stage, unwanted grain seedlings are killed and the yield of kept grain seedlings can be substantially increased.

Description

technical field [0001] The invention relates to the technical field of millet planting, in particular to a method for sowing and planting millet. Background technique [0002] The sowing method is one of the crop cultivation measures. Common methods include sowing, drilling, on-demand, etc. The appropriateness of sowing directly affects the growth and yield of crops. Sowing, that is, spreading seeds evenly on the surface of the field, is an ancient and extensive sowing method, which is simple and labor-saving, but it is inconvenient for intertillage and weeding in the later stage; Drilling, that is, sowing seeds in rows into the soil layer, the sowing depth is relatively consistent, and the seeds are in the row The distribution is relatively uniform, which is convenient for inter-row intertillage, weeding, fertilization and other management measures and mechanical operations. [0003] Millet, that is, millet, is a small and semi-dense crop, with a thousand-grain weight of a...

Problems solved by technology

Since millet is sown in summer, in order to save irrigation water, the sowing period is often adjusted so that the growth period overlaps with the rainy season. However, the torrential rain after sowing will easily cause the soil surface to harden, and the young shoots cannot reach the ground and curl up in the ground; or the seedlings have just emerged from the ground. Soon after the torrential rain, the mud was poured into the heart of the cat's ear leaf, causing the death of the seedlings; after the rain, it was sunny, and the seedlings after being unearthed could not resist the high temperature on the surface, resulting in burning seedlings; or because the seedlings were short and grew slowly, they were affected by the surface High temperature roasting leads to dead seedlings; therefore it is difficult to increase the yield of millet
