1. Early rice mid-till treatment. Use a deadly systemic herbicide to apply pesticide 10-15 days before the seedlings, 150-200 g of “Farmer Le 747â€, and use a broad-spectrum herbicide with contact killing to apply the pesticide 7 days before throwing. 200-250 grams of 20% grams of acre without a trace, is mainly used to prevent weeds between rice fields and fields. Within one week before spraying, maintaining a thin layer of water in the field will help the germination of weeds and soften the soil. When spraying, the fields should be drained, and try to choose sunny days. According to the dosage of the above agent, add 4 kg of ammonium bicarbonate to 60 kg of clear water, and evenly spray the weeds in the field. After 2-5 days of application, the soil is fully backwatered and immersed in paddy fields for 7-10 days until the water layer is naturally dry or the shallow water is drained. If the season allows, immersing the field for a longer time will have better results.
2, late rice free tillage treatment. Early rice should not be cut off prematurely before harvest to keep the soil soft. At the time of harvest, it should not be overripe. It should be suitable for 9 to maintain the freshness of the base of the rice piles. Harvesting should be as low as possible. The height of rice piles should not exceed 15 cm to 10 Below centimeters is appropriate. When the early rice is harvested, avoid the mud from adhering to the rice piles. After harvesting, drain the field water. In the evening of the same day, use 20% of the acre without trace, 200-250 grams of ammonium bicarbonate and 4 kg of ammonium bicarbonate, 60 kg of water, and evenly spray each. Rice piles and fields, field weeds. One day after application, paddy fields were fully backwatered and soaked in paddy fields for 2-4 days. After the water layer was naturally dried or drained, it was transplanted and transplanted. For no-tillage paddy fields that are very tense for the season, shallow water can be transplanted and transplanted after flooding the field for one day. However, this method needs to be carefully performed according to the specific circumstances.
Before throwing and transplanting, if it is found that the plots are too deep for footprints, they can be easily leveled with a farmer's shovel without plowing.
No-tillage paddy soil will not be soft and soft like traditional plowshares. When weeding, weeds and early rice piles may not be completely rotted, but it will not affect the normal growth of rice.
Application
The Double-lumen Endotracheal tube (also called Double-lumen endobronchial tube or DLT) is a type of endotracheal tube which is used in tracheal intubation during thoracic surgery and other medical conditions, to achieve the selective one sided ventilation of either the right or the left lung.
The main disadvantage of right sided tubes concerns the short length of the right main bronchus before giving off the upper lobe bronchus(risk of occusion)
Thus, left-sided tubes are usually preferred, even for right side surgery.
