What should we do if it rains after the latest cotton sowing?

After sowing, the overcast and rainy weather in the seedling stage of cotton will not only lead to seed emergence rate and seedling uniformity, but also affect the seedling growth quality of cotton and reduce the yield. Raining after cotton sowing is a headache, so what should we do when it rains after sowing? Let's take a look at the remedies.

1. Sowing with plastic film meets rain

For the planting method covered with plastic film, the stagnant water on the film should be cleaned up in time after rain. at this time, because the plastic film sowing line is generally lower than the ridge, the stagnant water on the film will accumulate on the sowing line after rainfall. If there is too much water, the film can not bear the pressure, leading to the rupture of the plastic film, a large number of Rain Water will flow into the sowing line, too much humidity under the film will cause cotton rot, or cause disease. In addition, the accumulation of water in the plastic film will affect the light transmittance and temperature of the plastic film, so the technology on the plastic film should be cleaned in time after rainfall, and at the same time, the shallow hoe should be ploughed between the film to break the consolidated soil and increase the soil temperature, which is beneficial to seed germination.

2. Sowing in the open field meets rain

If it is the case of sowing in the open field, the first thing to do after rain is ploughing and loosening the soil, breaking the soil consolidation and helping the seeds to break the soil and emerge seedlings. The depth of intertillage should also be treated differently. If the seeds are still sprouting, the depth of hoing should not exceed the depth of sowing, so as not to hoe the seeds directly out of the ground or move the position of the seeds, affecting the emergence of seedlings. If it is already sprouting and rooting and is about to break the soil, you can hoe some deeply, but you can't hurt the young roots, so as not to affect the growth of seedlings or cause dead seedlings.

3. According to the amount of rain

If it is a small amount of rainfall, it will not form runoff on the surface, there is no need for shell-breaking yield, seeds can rely on their own normal emergence. If it is a small amount of hard, it can be distinguished according to the sowing time after rainfall, and within three days of sowing, the wooden or iron drum with nail teeth can be slightly rolled to break the soil consolidation condition; if sowing within 5-6, the edged wooden or iron drum can be used to slightly crush the soil consolidation condition; and if sowing for more than a week, artificial seedling release should be adopted to break the soil consolidation so as not to hurt the buds.

The above is the introduction of what to do in case of rain after cotton sowing. I hope it can help you. If you want to know more about it, please follow us.
