Paddy field turning green manure
It is not too early or too late to turn over tillage at the right time. Generally, the ploughing is carried out according to the following two points: one is to look at the growth of green manure, and it is most suitable for ploughing in the flowering period; the second is to look at the target field, and plow the ploughing 10 to 15 days before sowing in the field or transplanting in the field. If the ploughing is too late, it may be It will produce a large amount of toxic substances such as hydrogen sulfide due to green manure decay, which will affect the normal growth and development of seedlings and produce black root dead seedlings.
The shallow water turns over the shallow water, the humidity is small, the oxygen is high, the temperature is high, the microbial activity is strong, and the green manure will decompose quickly and decay quickly. Therefore, green manure should be ploughed in shallow water, and it should not be allowed to be exposed to the sun after ploughing, otherwise it will reduce the fertilizer efficiency and it is difficult to rot.
It is advisable to apply 2,000 to 2,500 kilograms of green manure per mu of paddy field. If the yield of green manure is high, it can be cut into other fields. If the tillage is too late or the fresh grass is dry, 20 to 30 kilograms of lime powder should be applied per acre to accelerate the decay of green manure. However, the amount of lime should not be excessive, so as to avoid soil compaction and excessive alkalinity and affect rice growth.

As customers have higher and higher requirements for animal reproduction and animal disease diagnosis and treatment, traditional diagnostic methods such as visual inspection, stethoscope listening, thermometer inspection, and percussion and hammering can no longer meet the needs of animal husbandry production and veterinary clinics. Today, B-ultrasound is playing a big role in human medical diagnosis, and in the future, B-ultrasound will also play a role in animal medicine. We should promote the use of veterinary ultrasound scanner step by step according to the actual situation, popularize the knowledge of the use of veterinary ultrasound scanner, take this as an opportunity, and use it as a ladder to improve the level of veterinary practice in our country.
