In the recent stage, the rain in the southern region has been concentrated and concentrated in a relatively short period of time, resulting in serious water accumulation in some lower depressions, causing greater losses and adverse effects on local vegetable production. In response to the specific circumstances of the disaster relief, the disaster-reducing vegetable fields should promptly take remedial measures:
1. Timely drainage and flood control, and improve the field irrigation and drainage system. The soil of the vegetable field after the disaster relief is poor in air permeability, and the root of the plant is deficient in oxygen, which is prone to rooting. Therefore, it is necessary to drain the water in time after the rain. Farmers in open field should release all drains and reduce the time of water accumulation. If the water in the greenhouse is large and the water is deep, pump drainage should be adopted to reduce the occurrence of vegetable roots; It will produce high temperature and high humidity environment conditions, and the well water can be poured in time to reduce the ground temperature and reduce the generation of hot and humid air flow and reduce the occurrence of diseases.
2. Strengthen field and fertilizer management. For vegetables that are affected by heavy rain and flooded, timely correct and correct the leaves, rinse off the leaf surface sludge, remove the dead yellow leaves, diseased leaves, diseased fruit, timely tillage, timely topdressing or foliar application of foliar fertilizer such as potassium dihydrogen phosphate Promote the growth of vegetables. Pay attention to the ventilation of the vegetables in the greenhouse, and pay attention to proper shading after the rain. It can cover the shading net on the shed film to reduce evaporation and prevent the plant from wilting caused by physiological water loss.
3. Do a good job in pest control. After the rain, the humidity in the field is large, and the plant is damaged by the wind and rain, and the disease resistance is weakened. It is necessary to strengthen the prevention of various vegetable diseases and insect pests caused by high temperature and high humidity environment.
4. Repair and rebuild the collapsed greenhouse as soon as possible, and prepare for the early stage preparation of autumn and winter fruit and vegetable. Short-term strong winds cause some sheds to collapse and damage. The steel frame and cement racks should be strengthened and repaired as soon as possible. For the upcoming autumn and winter vegetable seedlings, the seeds, mulch, fertilizer and other materials such as tomatoes and sweet peppers should be prepared well. The breeding time of cantaloupe, cucumber and other varieties is in the middle of August, and preparations are made in advance to ensure the smooth development of nursery work.
5. Flooded plots will be rushed to harvest and harvest in time. For mature vegetables, timely harvest and reduce losses; for vegetable fields with long flooding time, most plant deaths or severely affecting yield, we should make arrangements to plant heat-resistant and fast-growing leafy vegetables; The nursery base should be planted, re-emerged as soon as possible, and strive for agricultural time to ensure the smooth production of autumn vegetables.
