Vegetable management before the rainstorm
Dredging channels should be done well to clear the ditch, the ditch, the lumbar ditch, and the ditch. Generally, the ditch is more than 80 cm deep, the ditch is more than 50 cm deep, the back groove is more than 30 cm deep, and the ditch is 20 cm deep. The high to low drop allows the rain to drain in time. Like the spring rain in the south, each block needs to be deep trench (more than 20 cm deep in the trench), narrow (within 90 cm wide), and high sorghum, which is good for drainage. Especially for a field with a large unit area and a length of more than 50 meters, a waist groove must be drawn in the middle, and a trench of 50 cm and a width of 40 cm must be drawn around the field.
Repair and reinforcement of the shed. Rainstorms are often accompanied by squally winds. Before the rainstorm, the shed film should be inspected, and the damaged parts should be repaired. Check whether the laminating line is firm. Be careful to blow the blast from the rupture of the shed film and smash the shed film.
Do a good job of covering the mulch film. The mulch film should be sealed with fine soil to prevent the wind from blowing through the planting hole and rupture the mulch. The side of the block should be sealed with mud to seal the film. Before the film is covered, the face should be made into a turtle shape and slightly flattened and snapped tightly so that the cover film can be pressed against the face to prevent the wind from smashing the film.
Pre-rain prevention. It is necessary to prevent and cure diseases after rain, and high temperature and high humidity are the conditions for some outbreaks of pests and diseases. It can be sprayed once with streptomycin sulfate, thiophanate-methyl or chlorpyrifos cyanide zinc (Kreis).
Vegetable Management after Rainstorm
Timely drainage and timely inspection of the field, found that the ditch is blocked by garbage, or if it is not cleared in time, it should be cleaned up, dredged in time, and drained in time to make the rain live in the field.
Cultivated loose soil After the heavy rain, the exposed vegetables are easy to cause soil compaction. The soil moisture is large and the air is not easy to cause the roots. The soil should be ploughed once in time.
Positive seedlings, replenishing seedlings Rainstorms often cause the plants to fall down or drench the soil around the plants, so that the roots must be exposed, and timely seedlings and seedlings should be added.
Fertilizing water to raise seedlings After the plants have resumed growth, they should be promoted with rare human waste water or urea.
After treatment and treatment of worms and rains, timely use phoxim or trichlorfon, chlorpyrifos, avermectin and other roots or spray to control pests, using procymidone (speed keiling), oxalin, chlorpyrifos, sulfate chain Medicines such as mycin and neomycin are used to control diseases such as gray mold and scab.
Do a good job in the management of the shed. After the heavy rain, the humidity in the greenhouse is also large. When the temperature is high and the humidity is high, the opening and closing management of the shed should be done. In principle, the opening and closing temperature of the newly planted greenhouse is 28 Â°C, that is, the morning is raised to 28 Â°C to open the shed door, and even the skirt is opened. In the afternoon, the skirt is lowered to 28 Â°C to close the skirt and the shed door. After planting the live vegetables, the opening and closing temperature is in principle controlled at 25 Â°C.
