What is the work of resuming production during spring ploughing in 2020? These four tasks should be done well during the epidemic!

Due to the impact of new pneumonia epidemic situation, many areas in order to prevent and control the epidemic situation closed villages and roads, to the current spring ploughing work to bring great pressure, but agricultural production more can not be delayed. So what are the resumption of spring ploughing in 2020? These four tasks should be done well during the epidemic!

I. Desertification and insect control in spring ploughing and resumption of production

The temperature at the beginning of 2020 is higher than that in previous years, and it is also a warm winter. The safe overwintering rate of some pests overwintering as larvae or pupae is higher than that in previous years. Therefore, we should make preparations for insect control. First of all, we should clear weeds and straws where pests overwinter. Therefore, we must clear weeds in the field before the beginning of spring.

II. Harrowing and preserving soil moisture in spring ploughing and resuming production

Last winter, there was more rainfall all over the country, which was conducive to spring sowing and seedling protection this year. However, as we all know, there are many strong winds in spring, and the temperature rises rapidly, so soil moisture is easy to lose. Therefore, we must do a good job in harrowing and preserving soil moisture. When the soil begins to freeze and thaw alternately, it is necessary to seize the time to form a loose soil surface with a solid structure. Generally harrow once every week or so, it is best to harrow 2 to 3 times, so that seedlings can be preserved after sowing.

III. Seed purchase and preparation for spring ploughing and resumption of production

At present, the epidemic situation of pneumonia caused by new coronavirus infection is grim. Prevention plans have been started everywhere. Everyone stays at home without leaving home. At this time, it is the peak period of seed purchase in the field. In order to reduce personnel flow and avoid personnel focus, the seed sales activities expected to be held by enterprises and dealers are cancelled accordingly.

Farmers need to pay attention to the publicity of seed varieties on various platforms, contact dealers in previous years more, and buy the seeds you need in time, especially some relatively tight varieties must contact relevant dealers in advance, in case they miss the opportunity and can't buy the varieties they want.

IV. Selection of fertilizer for spring ploughing and resumption of production

Seed fertilizer is essential in the preparation of sowing process, but how to choose is also very important, so as not to use the wrong fertilizer to cause burning seedlings, the following is not a fertilizer:

1. Corrosive fertilizer: ammonium bicarbonate is volatile and corrosive, easy to smoke seeds and seedlings; calcium superphosphate contains free sulfuric acid and phosphoric acid, which will cause damage to seed germination and seedling growth.

2, toxic fertilizer: urea in the growth process of crops, often produce a small amount of diacid, diacid content if more than 20%, the seeds and seedlings will produce poison. In addition, urea molecules with high nitrogen content penetrate into protein molecules of seeds, denature proteins and poison seed germination and young roots.

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

4, rural common manure: do seed fertilizer, if not decomposed, in the fermentation process release a lot of heat easy to burn roots, release ammonia will burn seedlings. Therefore, organic fertilizer should not be applied before decomposition. After high temperature fermentation and full decomposition, seed fertilizer can be made.

Although the epidemic situation is severe, agricultural production should not be abandoned. As long as prevention and control are well done, the problem of rural resumption will not be too big.
