What are the tasks for spring plowing and resuming production? Do these 4 tasks well during the 2020 pandemic

Due to the impact of the novel coronavirus pneumonia pandemic, many areas have sealed off villages and roads to prevent and control the pandemic, putting enormous pressure on the current spring plowing work, but agricultural production must not be delayed even more. So what are the tasks for resuming production during spring plowing in 2020? During the pandemic, these 4 tasks must be done well!

1. Clearing weeds and preventing pests as part of spring plowing and production resumption

The temperature at the start of 2020 was higher than in previous years, and it was another warm winter. The safe overwintering rate of some pests that overwinter as larvae or pupae was higher than in previous years, so preparations for pest prevention must be made. We should first clear away places where pests overwinter, such as weeds and straw, so before spring begins we must clear the weeds in the fields and around their edges.

2. Harrowing and raking to preserve soil moisture as part of spring plowing and production resumption

Last winter there was more rainfall than usual across the country, which is good for preserving seedlings in this year's spring sowing. But as everyone knows, spring has strong and frequent winds, and combined with the relatively rapid rise in temperature, soil moisture is easily lost, so everyone must do a good job of harrowing and raking to preserve soil moisture. When the soil begins to alternate between freezing and thawing, seize the time to harrow and rake while the surface is still frozen, forming a structure with a loose surface layer and a firm lower layer. Generally, harrow and rake once about every week, preferably 2 to 3 times, so that a full stand of seedlings can be ensured after sowing.

3. Purchasing and preparing seeds as part of spring plowing and production resumption

The current novel coronavirus pneumonia pandemic situation is severe, and all areas have activated prevention plans. Everyone is staying at home and not going out, yet this is also the peak period for purchasing field seeds. In order to reduce the flow of people and avoid gatherings, seed sales events that companies and dealers had planned to hold have also been canceled.

Farmer friends need to pay attention to publicity about seed varieties on various platforms, stay in contact with previous years' dealers, and purchase the seeds you need in time. Especially for some relatively scarce varieties, be sure to contact the relevant dealers in advance to avoid missing the opportunity and being unable to buy the varieties you want.

4. Choosing seed fertilizer as part of spring plowing and production resumption

Seed fertilizer is essential when preparing to sow, but how to choose it is also very important, so as to avoid using the wrong fertilizer and causing seedling burn. The following are fertilizers that cannot be used as seed fertilizer:

1. Corrosive fertilizers: Ammonium bicarbonate is volatile and corrosive and easily burns seeds and seedlings; superphosphate contains free sulfuric acid and phosphoric acid, which can harm seed germination and seedling growth. Generally, neither is suitable as seed fertilizer.

2. Toxic fertilizers: During crop growth, urea often produces a small amount of biuret, and if the biuret content exceeds 20%, it will be toxic to seeds and seedlings. In addition, urea molecules with high nitrogen content penetrate into the protein molecules of seeds, causing protein denaturation and harming seed germination and young roots.

3. Fertilizers containing harmful ions: Chemical fertilizers containing chloride ions, such as potassium chloride, will produce water-soluble chlorides after being applied to the soil, which is unfavorable for seed germination and seedling growth and easily burns seeds and seedlings. Nitrate ions contained in fertilizers such as ammonium nitrate and potassium nitrate are toxic to seed germination.

4. Barnyard manure commonly used in rural areas: If used as seed fertilizer and not decomposed, it releases a large amount of heat energy during fermentation, which easily burns the root system, while the ammonia gas released scorches seedlings. Therefore, undecomposed organic fertilizer should not be applied; only after being piled and composted for high-temperature fermentation and fully decomposed can it be used as seed fertilizer.

Although the pandemic is severe, agricultural production must not be abandoned. As long as prevention and control are done well, the problem of rural production resumption will not be too great.
