[0003] Chinese patent CN201310098363.9 discloses a method for close-planting corn with two rows and three plants in an extra-large ridge. This method can increase the yield per mu by 244 kg, but this method requires spraying of plant growth regulators, inter-cultivation, etc. in the middle, and the steps are cumbersome; Moreover, in the existing dense planting method, the emergence rate after sowing is low, the seedlings need to be replenished, and the phenomenon of non-bonding is easy to occur in the later stage.

Embodiment 1

[0025] A kind of method that dense planting improves corn yield, comprises the following steps:

[0026] (1) Select corn seeds with plump grains, consistent size, no injuries, and complete germs. First, soak the corn seeds in an aqueous solution of hexamethylenetetramine with a mass fraction of 5% (hexamethylenetetramine The aqueous solution should cover the seeds by about 2cm), during the soaking process, add 0.1mol phytic acid dropwise to each L of hexamethylenetetramine aqueous solution, stir evenly after the dropwise addition, soak for 10 hours, remove and dry the surface water; Put the dried seeds over the rice paste (just hang a layer of rice paste evenly on the corn kernel seeds), and then dress the seeds in the vinegar vinegar residue powder (just stick a layer of vinegar vinegar residue powder evenly on the surface of the corn kernel seeds , the thickness of the vinegar residue powder is about 1mm), and the pretreated corn seeds are used for later use;

Abstract

The invention relates to a method for improving corn output through condensed planting, and belongs to the technical field of agriculture. The method is implemented through steps of firstly, immersing corn seeds in hexamine solution, and dropwise adding phytic acid during the immersing process; after dropwise adding, stirring evenly and immersing for 8-10 hours; draining and drying to remove surface moisture; preparing the dried seeds to be rice paste; and then blending seeds in acid-sludge powder of table vinegar and obtaining the pre-treated corn seeds for future use; deeply loosening soil and then ridging, wherein the ridge direction is 25 degrees on the magnetic south by west, and the ridge is in the shape of trapezoid; then monoseeding at one side of the trapezoid ridge; after seedling, performing the regular farm field management. Through changing the ridge in due south and north directions to an oblique ridge, the ridge is fully ventilated and light-transmitted to reach the best illumination; meanwhile, the method improves the corn fertilization rate, increases the seed number of insemination and development, reduces the empty seed; meanwhile, the cluster is fast in development speed, output is high and quality is good.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for increasing corn yield through dense planting. Background technique [0002] Corn is one of the most important food crops in the world. The planting area and total output of corn in my country are second only to wheat and rice, and rank first in autumn grain crops. It is a high-yield crop. Corn kernels are rich in nutrients. In cities and rural areas in developed areas, corn is the main raw material for coarse grains and one of the raw materials for the food industry. In addition to eating, corn kernels and straw are also high-quality feed, which are widely used and used in large quantities. [0003] Chinese patent CN201310098363.9 discloses a method for close-planting corn with two rows and three plants in an extra-large ridge. This method can increase the yield per mu by 244 kg, but this method requires spraying of plant growth regulators, inter-cul...
