Problems solved by technology

This approach has a certain effect on reducing the damage of drought to maize emergence, but the effect is still unsatisfactory under severe drought conditions
The reason is that the seeds are planted on the top of the wet soil, the contact surface with the wet soil is small, and the water absorption speed is slow. Under the conditions of high temperature and drought, the evaporation of soil water is large, often causing the soil to dry before the seeds absorb enough water. Seeds can't germinate normally or germination is suspended, and the phenomenon of "dry seed" or "dry bud" will appear, resulting in a decrease in field emergence rate, lack of seedlings and broken ridges, affecting corn yield

Embodiment Construction

[0016] Press sowing test of corn with water: In mid-June 2013, corn was sown in the field under the condition of drought. Press sowing with water and sowing without pressing with water. The method of pressing and sowing with water is to open a sowing ditch in the field, pour enough water, plant the corn seeds in the ditch, press the seeds into the soil with a wooden stick, and then cover the soil with 3cm. The method of sowing with water without pressing is to open a sowing ditch in the field, pour enough water, plant the corn seeds in the ditch, and then cover the soil with 3cm. 200 seeds were sown per treatment, repeated 3 times. After 10 days, the seedling emergence rate was counted, and the emergence rate of the treatment with water and pressing was 85.5%, while the emergence rate of the treatment of watering without pressing was 71.1%. At the same time, it was found that the emergence of the former was uniform, while the size of the latter was quite different.

Abstract

The invention discloses a method for sowing corn by pressing with water. The method particularly includes during field sowing of the corn, sufficiently watering a sowing trench (hole), pressing seeds into wet soil, and earthing. Compared with a method without pressing with water, the method has the advantages of being high in emergency rate and uniform in seedling.

Description

technical field [0001] A method for sowing corn by pressing with water, relating to the field of corn sowing technology, more specifically, a method for pressing corn seeds into the soil after sowing the seeds on the basis of the method of sowing corn with water, and then covering them with soil . Background technique [0002] Summer corn is the main corn production mode in the central and eastern regions of my country, accounting for more than 95% of the corn production area in this region. The sowing period of summer maize coincides with the season when the temperature rises rapidly in early summer. Many years are often accompanied by drought and little rain, which is extremely unfavorable for maize sowing and seedling preservation. In order to alleviate the threat of drought, some people adopt the method of sowing with water to resist drought sowing. The method is to water the ditch or the hole after opening the sowing ditch or the hole, then sow the corn seeds, and then...
