Carrot pit storage to prevent rotten to start from the source
Recently, some farmers reported that the carrots in the pits had rotten cellars and asked how to prevent them. The author believes that the prevention of the incidence of carrot cellar storage should start from the source. 1. Chemical seed dressing. Seeds with seed weight of 0.3% of 70% mancozeb or 75% chlorothalonil were used before seeding. This method can prevent diseases such as black spot, black rot, and soft rot from the source and lay a good foundation for the storage of carrots. 2. Minimize soil moisture. In some years, especially around August 15th of the lunar calendar, rainfall continued during the late stages of carrot growth, resulting in a large area of ​​low-lying water. If the water is not removed in time, continuous soaking is sufficient to cause cracking, multiple roots, and even rot in the carrots. At the same time, various pathogens also multiply. At the time of harvesting, pathogens are also brought into the pits. When the temperature and humidity in the pits are appropriate, they will multiply into pathogens of mouse manure. The destructive power of this pathogen often causes the radish in the whole pit to rot, completely destroying the fruits of the farmers' labor. To this end, vegetable growers should conduct field management based on weather forecast information. Do not blindly water. 3. Before entering the pit, handle it carefully. Before carrots enter the pit, the following points should be made in the process of removing the tops: First, it is better to cut more and cut more; second is to find that the black heart is not removed into the cellar on the spot; the third is to keep small without cracking. The fourth is to make the carrots harvested as much as possible to receive strong sunlight, the time should not be less than one and a half hours. 4. The specifications of the pit should be appropriate. Digging pits try to choose east-west direction; the width does not exceed 1 meter, the depth is 83 centimeters, and the upper and lower limit does not exceed 2 centimeters; the amount of lime powder should be scattered in the bottom of the pit to kill pathogens; the thickness of carrots should not exceed 40 centimeters. In order to cover the soil by stages, the temperature in the pit is always maintained at 0°C to 3°C. At least 3 times of soil should be covered in general years, and a height of 10 centimeters should be set aside so that the special cold can be covered with earth again.
