Advantages and disadvantages of cotton machine sowing

Last Updated: 2024/11/06, In recent years, cotton sowing in Ninghe County has always been maintained at about 300000 mu, accounting for more than 50% of the arable land. Since the introduction of experimental and demonstration machine sowing technology in 2002, the popularized use area has reached more than 70% this year, injecting new vitality into cotton production in Ninghe County. The main methods are as follows: first, carry out machine ploughing, winter irrigation or spring irrigation, preserve soil moisture before sowing, flatten the soil with sowing seeds, then spray herbicides on the surface, and then sow seeds with a seeder: ditching, fertilizing, sowing, soil mulching, film mulching, and running water operation.

In recent years, cotton sowing in Ninghe County has always been maintained at about 300000 mu, accounting for more than 50% of the arable land.

The main methods are as follows: first, carry out machine ploughing, winter irrigation or spring irrigation, preserve soil moisture before sowing, flatten the soil with sowing seeds, then spray herbicides on the surface, and then sow seeds with a seeder: ditching, fertilizing, sowing, soil mulching, film mulching, and running water operations. finish at once (the seeds must be light seeds).

According to our investigation and experience, machine broadcasting mainly has the following advantages:

The main results are as follows: 1. As the trial amount of seeds and chemical fertilizers can be regulated, the effects of uniform sowing and fertilization, high speed and good quality can be achieved.

2. Save labor and reduce labor intensity: one seeder uses a hand belt, and three people (including robot hands) can sow more than 20 mu a day, which is 15 times that of manual mulching and sowing, especially for continuous operation, and the sowing efficiency is higher. It is very suitable for the popularization and application of farmers and large contractors with large sowing area and less labor.

This year, through our cotton seedling stage in-depth machine sowing plot survey, but also found a disadvantageous side: where the ground is uneven, lack of soil moisture, the emergence of land is not all uneven. The problem is: to adopt machine sowing, winter irrigation or spring irrigation must sow soil moisture in advance, but in recent years, most of our county is rotary tillage and shallow ploughing layer, the field water holding capacity is small, the effect of soil moisture conservation is poor, and the time is short, so it is difficult to sow enough moisture in the appropriate period. therefore, it is difficult to produce whole seedlings in high-lying and uneven land, resulting in the phenomenon of missing seedlings and broken ridges.

In short, we believe that the advantages of machine sowing outweigh the disadvantages. As long as the soil moisture is sufficient and the sowing quality is ensured, the whole seedling can be sowed at one time.
